arkansas winter forecast 2022

Part I: Month-to-month variability. This winter is indeed looking like a snowy one across most of the northern tier of the contiguous United States, but AccuWeather senior meteorologist Paul Pastelok says, there is more to the forecast than just snowstorms. Our forecasts are not direct predictions of rain/snow. MonthlyandDailyvalues for the Arctic Oscillation Index are available from NOAA's Climate Prediction Center. The current season (2022-23) AWSSI can be found here. Climate in Arkansas Arkansas, Arkansas gets 51 inches of rain, on average, per year. Webinar for the NWS Central Region, February 2017. for the Upper Mississippi River Valley Could the upcoming flu season spell trouble for the US? Consequently, locations in the mid-latitudes are more likely to experience outbreaks of frigid, polar air during winters when the AO is negative. Includes Daily Risk of Precipitation, High/Low/Average Temperatures, Heating/Cooling Degree Days and Growing Degree Days, Transition Day Start or End of a Risky Period. Specifically, the lingering water vapor from the January eruption could indirectly help to fortify the polar vortex over the North Pole, preventing it from dipping down across North America. Schools NOAA's Climate Prediction Center (CPC) forecastfor the upcoming winter months of December-February: While a weak to moderate La Nia is expected to impact the weather across much of the United States, its impacts in the Upper Mississippi River Valley can be highly variable with both temperatures and precipitation. However, no two La Nia winters will have identical precipitation patterns. Lets dig a little deeper and look at some of the characteristics within these two convective phases (Figure 3). Central and Southern California still have a chance to receive beneficial rainfall and mountain snow this winter, but the storms are likely to hold off until after the start of 2023. December 31, 2014. Atmospheric angular momentum is related to ENSO and also shows the impact of tropical forcing on tornado activity (Gensini and Marinaro, 2016). 2000, Cassou, 2008, Lin et al. La Nina means that the eastern equatorial Pacific sea-surface temperatures are colder than normal. Please select one of the following: is slightly favored across the Upper Mississippi River Valley. Pastelok and his team of long-range forecasters are predicting a "triple dip La Nia," as it is the third winter in a row that La Nia will shape the weather patterns across the U.S. Theseries of maps to the right shows temperature patterns across the continental United States compared to the 1981-2010 average for every winter seasonDecember through Februarysince 1950 that coincided with La Nia conditions in the equatorial Pacific Ocean. The MJO consists of two parts, orphases: one is the enhanced rainfall (orconvective) phase and the other is the suppressed rainfall phase. In the northern Plains, this can result in AccuWeather RealFeel Temperatures plummeting toward 50 degrees below zero. Last day with 1 inch of snow on the ground The longest La Nia lasted 33 months. Positive values indicate increased activity, and negative values indicate decreased activity compared to the long-term average (1979-2015). Arctic Oscillation) may be at play and is worth further investigation. On Jan. 15, 2022, the Hunga Tonga-Hunga Haapai volcano, an underwater volcano located about 2,200 miles northeast of Sydney, Australia, erupted in grand fashion, sending a significant plume of gas, ash and water vapor high into Earths atmosphere. Lewiston, ME: Every year since 1818, the Farmers' Almanac provides an extended weather forecast that helps people plan ahead. "The last two Februarys have featured significant cold waves for the central and southern Plains," Pastelok said. Winter Forecast 2022 to 2023 The Old Farmer's Almanac Winter Forecast for U.S. Winter has arrived! The question How severe was this winter? does not have a simple answer. 2: animation). Hospitals / Nursing Homes Although 2022 couldn't come close to the robust number of deals announced in 2021, it was on par with previous years with more than 1,070 VC-backed startups Derek Groff, ASA en LinkedIn: Forecast: Startup M&A Could Pick Up In 2023 As Fundraising Tightens Further Science / Research Temperatures 48 / 33 Rainy Days 5 Snowy Days 2 Dry Days 24 Rainfall 2.72 in Sun Hours 8.6 The North Atlantic Oscillation (NAO) index is based on the surface sea-level pressure difference between the Subtropical (Azores) High and the Subpolar Low. Over Indonesia, there is more rising air motion and lower surface pressure. The Euro precipitation forecast outlines the major areas of concern with our snowfall outlook. The new storm track during the second half of the winter will focus on the eastern Plains and mid-Mississippi Valley, but bouts of heavy snow, and even blizzard conditions, cannot be ruled out on the northern and western sides of these storms. The MJO can produce impacts similar to those of ENSO, but which appear only in weekly averages before changing, rather than persisting and therefore appearing in seasonal averages as is the case for ENSO. These winters averaged 48.9"of snow which was4.2"less than the 1991-2020 normal of 53.1". Climate Variability: Madden-Julian Oscillation (MJO), Author:Jon Gottschalck Warmer and drier winters are more likely during La Nia over more southern states, and this is exactly where seasonal snowfall tends to be reduced (4). this winter's forecast for the northern half of the United States is expected to be colder than average with more snow than usual in . AccuWeather's team of long-range forecasters, led by Senior Meteorologist Paul Pastelok, has made its annual prediction for the upcoming winter season, giving people all across the country time. Even when it does snow during the week, the impacts on daily routines may not be the same as they were a few years ago. Equal chance display areas where confidence is low, so there is an equal chance of it being among the warmest third, near-normal, or among the coldest third. | Arctic Arkansas, Tips to save money this winter season | Arctic Arkansas. River Stages Several times a year the MJO is a strong contributor to various extreme events in the United States, including Arctic air outbreaks during the winter months across the central and eastern portions of the United States. | Arctic Arkansas, RELATED: Tips to save money this winter season | Arctic Arkansas. Meanwhile, Rochester has had 10 near-normal, 7 among the wettest third, and 7 among the driest third. Last year, there were several snow events across the region that blanketed some southern cities. The best opportunity for snow or wintry precipitation across the interior Southeast will arrive in January and early February with one or two snowfall events possible in this timeframe. However, these figures are based on about 20 different La Nia episodes, many of them from the 1950s, 1960s, and 1970s, and we have not removed the longer-term trends from the temperature and precipitation data used here. Weak LaNias (41% chance for this winter) tend to favor colder- and near-normal winters. Instead, it's the water temperature in the Gulf of Mexico and along the Atlantic Seaboard that has meteorologists' attention. Other climate phenomena, such as the Arctic Oscillation or the Madden Julian Oscillation, as well as the random nature of weather, can also play a large part in how winter turns out. Every year the Farmer's Almanac releases their prediction for the upcoming winter, and the forecast for 2022-23 is looking like a very wet and cold winter. This once-in-a-lifetime eruption was so powerful that it sent shockwaves around the world and caused the amount of water vapor in the stratosphere to increase by around 5%, according to a recent report by The Associated Press. Figure 1: Difference from average rainfall for all MJO events from 1979-2012 for November-March for the eight phases described in the text. Will it be a snowy one? $13.99 buys a year's worth of wisdom in the palm of your hands, online community access and a 2023 Farmers' Almanac ! During La Nia, the surface winds across the entire tropical Pacific are stronger than usual, and most of the tropical Pacific Ocean is cooler than average. However, tornado and severe weather activity is more variable (noisier and harder to predict) than ordinary weather (think temperature and precipitation), and any ENSO signal is harder to see. As students were heading back to the classroom for the start of the new school year, New York City School Chancellor David C. Banks announced that there will be no snow days during the 2022-2023 academic year, NBC News reported. Meanwhile, there have been more near-normal winters (6) than either colder (3) or warmer (4) than normalat Rochester. In general, the stronger the La Nia, the more reliable the impacts on the United States. Figure by climate.gov; data from the authors. In the enhanced convective phase, winds at the surface converge, and the air is pushed up throughout the atmosphere. Precipitation Reports When forecasting the weather, it is nearly impossible to accurately predict anything more than a week away. Generalized Walker Circulation (December-February) anomaly during La Nia events, overlaid on a map of average sea surface temperature anomalies. "But we can see some moderate systems and occasionally one bigger period where it does get hit hard in the Northwest.". Despite the weather pattern shaping up in a similar matter as it has the past two years, Pastelok warns that this winter "will be a little different from last year, as far as the primary storm track across the West Coast.". Instead of cooling the surface, the reaction could be more warming. Abstract | Full Text | PDF (2545 KB). The location of the convective phases is often grouped into geographically based stages that climate scientists number 1-8 as shown in Figure 1. In New England, for example, higher frequencies of coastal storms known as "Nor'easters" are linked to AO's negative phase. As of Tuesday, Sept. 20, 74% of the western U.S. was experiencing at least a moderate drought, 18% was experiencing extreme drought, and there were pockets of exceptional drought -- the most severe of drought categories -- in California's San Joaquin Valley, central Oregon and central Utah. Drought is expected to impact the middle and lower Mississippi Valley this winter. But will there be more snow? Favorable things for a colder-than-normal winter. Brutal Cold or Terrible Torch? AccuWeather's approach to concocting the winter forecast, one of its most highly-anticipated seasonal outlooks, is a bit different: The process involves a team of veteran long-range forecasters analyzing computer models, looking at how previous winters have played out and using their own personal experience to determine if it's going to be a snowy winter, if and when the polar vortex will unleash Arctic air across North America and whether it will be a good season for skiers. The US average is 205 sunny days. The green shading denotes conditions favorable for large-scale enhanced rainfall, and the brown shading shows conditions unfavorable for rainfall. However, in the last week, the low-level trade winds weakened in association with sub-seasonal tropical variability. Image Credit: Climate Impacts Group, University of Washington. (2012) and Allen et al. If you're planning to visit Arkansas in the near future, we highly recommend that you review the 14 day weather forecast for Arkansas before you arrive. The precipitation pattern, presented above, shows negative anomalies (indicating below-normal rainfall) across the entire southern part of the country with a weaker signal of above-average precipitation in the Ohio Valley and in the Pacific Northwest and the northern Rockies. That provides a significantly different picture, with the average of the latest events much warmer than the earlier ones. April 27, 2017. The AWSSI is not limited to meteorological winter (December February) but is intended to capture winter weather from its earliest occurrence to its last. 80% of La Nia brings warmer than normal conditions to Arkansas. The volcano spewed an unprecedented amount of debris high into Earth's atmosphere which, as Pastelok will explain, could still be having an effect on the weather on a global scale. View detailed forecast, WeatherTAB 2023. From the abundance of acorns in the fall to the bushiness of squirrel tails, there are many fanciful forecasting techniques have been used over the years as a means to glean a glimpse of what the weather will be like in the upcoming winter. Midwest La Nia Seasonal Snow Departures (24 Winters since 1949-50), Author:Midwestern Regional Climate Center. Severe weather as a whole decreases across the U.S. during the winter months, but it can still be disastrous across the Southeast during this time of year. J. Other climate phenomena, such as the Arctic Oscillation or the Madden Julian Oscillation, as well as the random nature of weather, can also play a large part in how winter turns out. This allows a comparison of the relative contribution of each to the total score. This failure of the typical pattern occurs because La Nia is never the only thing that influences the climate over the United States during the winter. Winter brings many ups and downs. In much of the U.S., La Nia conditions are associated with increases in these environmental factors and in tornado and hail reports. Snowfall for the season as a whole is likely to be below normal for most of the central Appalachians, Ohio Valley and interior mid-Atlantic, but precipitation could end up above normal with a few all-rain events likely to unfold throughout the winter. This year, with the extreme summer weather conditions broiling the country, and the growing concern over the rising costs of heating oil, Farmers' Almanac is releasing its winter weather forecast earlier than ever. During this time, we see good potential for heavy snow that may reach as far south as Texas and Oklahoma . Baldwin, 2002: Atmospheric Processes Governing the Northern Hemisphere Annular Mode/North Atlantic Oscillation. Such rising air motion in the atmosphere tends to increase condensation and rainfall. Since 1900, this has only happened 4 times. Follow Us On Social Media, Weather Safety The seasonal data is then subject to quality control, and seasons missing data that would contribute 5% or more of the seasons AWSSI are removed. Use commonly available datamax/min temperature, snowfall, and snow depth or precipitation, Create a historical database of AWSSI for any location with daily temperature, snow, and precipitation data, Allow comparisons of season-to-season severity at one location in the context of the climatology of that location or between locations, Use as a baseline to scale subjective impacts such as those to snow removal, commerce, and transportation, Does not include wind (e.g. In the South and Southeast, where the signal is strongest, we see a clear shift in activity with the ENSO phase, but with a tremendous range of variability, meaning some El Nio years still have high severe weather activity, and some La Nia years are relatively inactive. Given the northward shift of the storm track, relatively cold and wet conditions are favored over the northern Rockies and northern Plains, resulting in the enhancement of snowfall. Locally,wetter-than-normal (not just a hundredth of an inch wetterthan normal, but among the wettestthird of the winters from 1991-2020)is slightly favored across the Upper Mississippi River Valley. The global Winter Sports industry report provides top-notch qualitative and quantitative information including: Market size (2017-2021 value and 2022 forecast). Mayfly Tracking, Latest Overall we are expecting much of western Arkansas to receive 6-12 inches of snow by mid March. Zhou S., M. LHeureux, S. Weaver, and A. Kumar, 2012: A composite study of MJO influence on the surface air temperature and precipitation over the Continental United States. Res. 8, August 2015: 1693-1712. Meanwhile, drier-than-normal conditions are seen across central South America. 1: The tornado environment index (TEI) and hail environment index (HEI) are functions of monthly averages of convective precipitation, convective available potential energy, and storm-relative helicity. During the years of 2022, 2023, and 2024, an event like no other struck the ENTIRE United States, unleashing total chaos upon the country. Note eastward shifting of shaded areas with each successive numbered phase as you view the figure from top to bottom. Differences between the two periods for the precipitation composites are much smaller and therefore are not shown here. Our weather forecast can give you a great sense of what weather to expect in Arkansas in January 2023. Overall, La Nina conditions are associated with enhanced U.S. tornado activity, but more detailed aspects of ENSO may also be relevant (Lee et al., 2012). The bulk of accumulation will occur by daybreak Thursday with 1 to 2" per hour rates common. United States Snow, Arkansas Long Range Weather Forecast 30 days and beyond. Preparedness The most obvious reflection of the phase of this oscillation is the north-to-south location of the storm-steering, mid-latitude jet stream. They often noticed regular oscillations in winds (as defined from departures from average) between Singapore and Canton Island in the west-central equatorial Pacific (Madden and Julian, 1971; 1972; Zhang, 2005). 6]. WRN Ambassadors, Additional Information The anticipated winter pattern will not necessarily mean a parade of non-stop storms for Washington, Oregon and Idaho, as Pastelok explained that the primary storm track will focus more on western Canada. The NAO index is obtained by projecting the NAO loading pattern to the daily anomaly 500 millibar height field over 0-90N. In general, the stronger the La Nia, the more reliable the impacts on the United States. Equal chance display areas where confidence is low, so there is an equal chance of it being among the wettest third, near-normal, or among the driest third. Accumulations of the temperature and snow components of the index are computed separately and then added together for the total index. Favorable things for a wetter-than-normal winter. As the calendar turned to December, the storm track shifted northward, directing the rain and mountain snow toward Washington and British Columbia, Canada. This video and related map images can also be accessed at https://www.noaa.gov/news-release/us-winter-outlook-warmer-drier-south-with-ongoing-la-nina. AccuWeather meteorologists are predicting that most of the contiguous U.S. will experience a mild start to winter, but some of the warmest weather throughout December could be focused on the central Plains. Thompson, D.W.J., and J.M. "There is a chance once again on this third La Nia winter, that cold air reaches this region." Central Arkansas can expect to see slightly warmer and wetter than average conditions. La Nia refers to abnormally cold water temperatures across the central and eastern equatorial waters (5N-5S, 120-170W)] of the Pacific Ocean. However, because temperature also plays an important role in snowfall, some predictability is likely nonetheless. Strongest Stratospheric Cooling on Record - 2022 (Southern Hemisphere) Full Report - here 3. In the maps, the CPC forecasts show the probability of the favored categoryonly when there is a favored category;otherwise, they show EC (equal chances). You can expect to have about 11 days with temperatures under 32F, or 38% of time. For example, 9 of the 11 strong and moderate events show wetter-than-average conditions in the Pacific Northwestthough the intensity of the anomaly varieswhich is most winters, but not all. When La Nia develops across the tropical central/eastern Pacific Ocean, it can affect areas thousands of miles away, including the United States. Precipitation tends to be below-average across the southern tier of the United States and wetter than average across the Pacific Northwest and Ohio Valley. The MJO becomes organized during late March through May as the green shading covers one half of the planet, and brown shades the other half all along as these areas move west to east with time. Forecast Discussion Every day can be drastically different than the next. Spells of colder weather during the early part of the ski season could help the resorts that are able to generate their own snow. This tends to bring a jet stream that dives southeast across the Rockies and into the central U.S. and Great Lakes, before wrapping back northeast into New England. WeatherTAB helps you plan activities on days with the least risk of rain. Little Rock, AR Winter Weather Forecast | AccuWeather Snow and Ice Outlook There are currently no active snow events at this location. Last January, accumulating snow was observed on just four days throughout the month, amounting to 12.3 inches. The Farmers' Almanac released their winter weather outlook, and Oklahoma is predicted to have chilly, snowy conditions throughout the season. The snowfall totals will be boosted by a few nor'easters, with January and March bringing the highest chances of powerful coastal snowstorms. THV11 weather forecast | Dec. 31, 2022. Stronger cold fronts? Passing clouds. To first order, the green shading areas correspond to the extent of the enhanced convective phase of the MJO and the brown shading areas correspond to the extent of the suppressed convective phase of the MJO.
