Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 245 AM EST Mon Feb 08 2021 Valid 12Z Mon Feb 08 2021 - 12Z Wed Feb 10 2021 ...Bitterly cold temperatures and dangerous wind chills to persist across the north-central United States... ...Two rounds of light snowfall and freezing rain to impact areas from the Central/Southern Plains to Northeast... Residents across the Northern Plains and Upper Midwest will start off the work week with continued below average temperatures and brutal wind chills. Wind Chill Advisories and Warnings remain in effect from Montana to the U.P. of Michigan. Wind chill values well below zero and as low as -50 degrees could be experienced at times across this region. While not as extreme, this cold airmass stretches as far south as Oklahoma and as far east as the Ohio Valley. Widespread temperatures 20 to 30 degrees below average can found across these areas thanks to a strong high pressure system and constant flow of bitter arctic air from southwest Canada. Unfortunately, these below average temperatures don't appear to moderate or exit in the foreseeable future. Looking for some mid-winter warmth? Much of the Southeast and south-central U.S. will enjoy above average temperatures through Wednesday. With cold air in place across the northern U.S. and a stalled frontal boundary bisecting the middle of the country, multiple rounds of wintry precipiation are expected from the Southern/Central Plains to the Northeast. Starting with today, light snowfall is expected to continue across the Northern Rockies and add to the recent fresh snowpack that has accumulated over the last several days. Winter Weather Advisories and Avalanche Warnings are in effect across much of the mountainous terrain in Montana and northern Idaho. Light snow will also be found across the Central Plains and Midwest today as a wave of low pressure develops along the frontal boundary and moves toward the Northeast by Tuesday. Generally around 2 to 4 inches of snow can be expected for these locations, with higher amounts up to 6 inches possible across the Northeast. A mix of sleet, snow, and freezing rain will be possible across northeast Oklahoma and southern Missouri through tonight as well. By Wednesday morning another round of wintry weather is expected to develop across similar regions from the southern Plains to Midwest. More impactful freezing rain accretion will be possible and this time stretch from northeast Oklahoma to northern Kentucky. Snell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
