The AWSSI is not limited to meteorological winter (December February) but is intended to capture winter weather from its earliest occurrence to its last. Figure by climate.gov; data from the authors. La Nias can be highly variable with precipitation. AccuWeather long-range forecasters are predicting that 40 to 50 inches will accumulate in the city, around the average snowfall amount of 49.2 inches. There has been a fair amount of variability in the winter temperature and precipitation patterns during La Nia, but also that there are some clear tendencies for above or below normal temperature or precipitation in some regions. Meanwhile, drier-than-normal conditions are seen across central South America. Meanwhile, there have been more near-normal winters (6) than either colder (3) or warmer (4) than normalat Rochester. MonthlyandDailyvalues for the Arctic Oscillation Index are available from NOAA's Climate Prediction Center. The AWSSI has been processed for 52 locations across the continental U.S. to provide a variety of locations in different climate regimes for analysis. "But we can see some moderate systems and occasionally one bigger period where it does get hit hard in the Northwest.". The Accumulated Winter Season Severity Index (AWSSI) was developed to objectively quantify and describe the relative severity of the winter season. 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. Arctic Oscillation) may be at play and is worth further investigation. For temperature, theres a strong tendency for temperatures to be below average across some of the West and North, particularly in the Northern Plains, with a weaker signal for above-average temperatures in the Southeast, as shown in the image below. An overturned tree sits in front of a tornado-damaged home in Mayfield, Ky., on Dec. 11, 2021. 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 North Atlantic Oscillation (NAO) index is based on the surface sea-level pressure difference between the Subtropical (Azores) High and the Subpolar Low. Seasonal (May-July) averages of Gulf of Mexico SST can be predicted with some skill (Jung and Kirtman, 2016). 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.

Winter precipitation differences from average (inches) during La Nia winters dating back to 1950. United States Snow, Arkansas Long Range Weather Forecast 30 days and beyond. Rainfall increases over Indonesia (where waters remain warm) and decreases over the central tropical Pacific (which is cool). varies on a week-to-week basis). "The water temperatures are going to have a big impact going forward this season," Pastelok said. "Unfortunately, we have bad news as far as the drought goes in parts of California, Nevada and the Southwest," Pastelok said. River Stages 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. Hot Chocolate Warning In The East and South Note eastward shifting of shaded areas with each successive numbered phase as you view the figure from top to bottom. 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. SkyWarn However, if it does rain/snow during the month, expect most of it to occur on higher risk days. Try searching for a city, zip code or point of interest. Journal of Applied Meteorology and Climatology, Vol. 3], reflecting the stationary pattern of below-average temperatures across the eastern Pacific Ocean[Fig. Plan for hazardous to dangerous travel overnight and a slower than normal Thursday morning commute. Indeed, historic tornado outbreaks in1974,2008,and2011started during La Nia conditions. As the calendar turned to December, the storm track shifted northward, directing the rain and mountain snow toward Washington and British Columbia, Canada. Follow Us On Social Media, Weather Safety CPC 2022-23 U.S. Winter Outlook: The following video highlights from NOAA's 2022-2023 Winter Outlook that provide seasonal predictions for temperature, precipitation, and drought. 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. Based on climate analysis (3) from this new snow dataset, we see that La Nia favors increased snowfall over the Northwest and the northern Rockies, as well as in the upper Midwest Great Lakes region. Science, 293, 85-89. J. Atmos. Huntsville, Alabama, measured 5.2 inches of snow last winter, more than double the annual average of 2.4 inches. There is a 76% chance of La Nia during the Northern Hemisphere winter (December-February) 2022-23, with a transition to ENSO-neutral favored in February-April 2023 (57% chance). April 27, 2017. On average, the winter tends to be 1-2 degrees warmer December through February. Very few winters have been in the coldest third over the past decade (optimal climate normal). Thus, the mid-latitudes of North America, Europe, Siberia, and East Asia generally see fewer cold air outbreaks than usual during the positive phase of the AO. In the northern Plains, this can result in AccuWeather RealFeel Temperatures plummeting toward 50 degrees below zero.

The Arkansas weather forecast often changes dramatically due to surrounding weather influences. 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. Our overall forecast: -More warm days than cold days, overall warmer than average -More total snow, but fewer. His unchanging location is associated with the persistent changes intropical rainfalland winds that we havepreviously describedas being linked to ENSO.

However, as is evident in these maps, there is a great deal of variability even among strong La Nia events. where snowfall is greater than average and brown shows where snowfall is less than average. By However, no two La Nia winters will have identical temperature and precipitation patterns across the United States. Residents across the Northeast and Midwest will experience a few winter previews in November and December as waves of cold air dive down from Canada, but the biggest blasts of cold air will hold off until later in the winter.
