How bad is winter 2022-2023 be? Our weather forecast can give you a great sense of what weather to expect in Arkansas in January 2023. Clark said that in some instances, remote learning could be a possibility in the event of inclement weather, according to LocalToday. The clash of cold air with lingering warmth could spark an out-of-season severe weather event in the Midwest or Ohio Valley late in November or in December. The AWSSI is calculated for each season from 19501951 to 20122013. Also, there is a tendency toward below-average snowfall over the mid-Atlantic, New England, and northern and central Plains, which is not seen during weak La Nia. The firm predicts temperatures that are normal to slightly below normal. 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. Splitting La Nia events into strength reveals some interesting differences worth investigating further. Notice how the shading returns to the same location on the order of about 45 days. Gulf of Mexico sea surface temperature is close to the part of the U.S. most strongly impacted by severe weather: warm Gulf of Mexico surface water in spring enhances low-level moisture transport and southerly flow and is associated with enhanced US tornado and hail activity (Molina et al., 2016). However, because temperature also plays an important role in snowfall, some predictability is likely nonetheless. There will be a few chances for Arkansas to pick up some of this cold air. Figure 1: Difference from average rainfall for all MJO events from 1979-2012 for November-March for the eight phases described in the text. View detailed forecast, WeatherTAB 2023. Courtesy of the Farmer's Almanac. From the AGU monograph on the North Atlantic Oscillation, 293, 85-89. Take a look at the official winter predictions with a summary from The 2023 Old Farmer's Almanac. Its fairly trivial to break the sample size in half and compare the temperature patterns for the older half to the more recent half. In 2012, a tornado outbreak across Louisiana, Mississippi and Alabama on Christmas Day spun up 34 twisters and 84 damaging wind reports and cut power to families as they tried to celebrate the holiday with their friends and families. Forecasting,29, 2338. The Farmers' Almanac, which has made weather predictions for the U.S. since 1818, has released its 2022-2023 winter forecast. 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. Outside of that region, New England is one of the only areas east of the Rocky Mountains where snowfall could end up being above normal. 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). This winter, AccuWeather is predicting that Washington, D.C., will experience accumulating snow on only three to five days throughout the season with total accumulations amounting to 6 to 10 inches, just below the average of 13.7 inches. NOAA Climate.gov image using data fromESRLandNCEI. Posted: Oct 15, 2021 / 05:14 PM CDT. Descriptive categories were assigned to each quintile as follows: CONUS AWSSI during La Nia (23 Winters since 1954-55), The Accumulated Winter Season Severity Index (AWSSI) 2009, Zhou et al., 2012, Riddle et al., 2013, Johnson et al., 2014). Dynamical climate models are suggesting wetter-than-normal across much ofWisconsin. This allows a comparison of the relative contribution of each to the total score. 60-70% of La Nia winters in the past have brought more snowfall to Arkansas. Last winter, Boston finished the season with 54 inches of snow with 23.5 inches falling during a blizzard on Jan. 29. 2]. The Farmers Almanac's 2022 - 2023 extended winter forecast for Arkansas calls for a "Chilly near normal precipitation" winter. 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. Brian Lada, AccuWeather meteorologist and staff writer, Published Sep 28, 2022 2:35 PM CET Animated map showing accumulated hourly precipitation from atmospheric rivers for Dec. 25th at 4 p.m. Pacific through January 4 at 12 p.m . Whatever your #DressCode, there are 3 ITEMS I recommend every While increased tornado activity is generally associated with La Nina conditions, blaming this years high activity on the weak La Nina conditions would be exaggerating the strength of the historical relationship (footnote 2). This will be the general track for storm systems this season. Unlock advanced, hyperlocal severe weather alerts when yousubscribe to Premium+on theAccuWeather app. Out of the 6 moderateLa Nias, 4 have been among the coldest third, and 2 were near-normal. Storm Summaries Around the same time that the coldest air of the season freezes the Plains, AccuWeather meteorologists say, the overall track of storm systems across the U.S. could change. The changes in spring (March-May) are similar to those during winter, but somewhat weaker. The more vigorous storm track and slight tilt toward colder temperatures over the northern tier of the U.S. during La Nia modestly increase the chance of a relatively snowy winter. As disruptive as the storms may be to travel and the normal daily routines of millions of people across the region, any precipitation, both liquid and frozen, will be welcomed across the central Plains. Pastelok added that if the water in the Gulf of Mexico and along the Atlantic coast remain warmer than usual, there is the chance for a "potentially big system" to develop during the second half of the winter that could impact the East Coast.

Below are the temperature, precipitation, and snow data for La Crosse, WI, and Rochester, MN. An Accumulated Winter Season Severity Index. 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. At the top of the atmosphere, the winds reverse (i.e., diverge). Thus, the AO can have a strong influence on weather and climate in major population centers in North America, Europe, and Asia, especially during winter. Meanwhile, drier-than-normal conditions are seen across central South America. And some impacts are more reliable than others. The CPC winter temperature forecasts to the right show the most likely outcome where there is greater confidence, but this is not the only possible outcome. The National Oceanic and Atmospheric Administration has issued a 90-day forecast for anticipated winter weather around the Pacific Northwest between December of 2022 and March 2023.

Mayes Boustead, Steven D. Hilberg, Martha D. Shulski, and Kenneth G. Hubbard. 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. 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.
