Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 238 AM EST Sun Feb 07 2021 Valid 12Z Sun Feb 07 2021 - 12Z Tue Feb 09 2021 ...Fast-moving coastal storm to bring accumulating snow from the Mid-Atlantic to southern New England today... ...Consistent light snow to persist across the Northern Rockies and Central Plains before moving east into the Midwest and Ohio Valley by Monday... ...Prolonged period of life-threatening wind chills to continue for the foreseeable future throughout the Northern Plains and portions of the Midwest... A low pressure system taking shape along the Southeast coastline this morning is set to race up the East Coast today and bring potentially hazardous winter weather for several major cities from the Mid-Atlantic to New England. Snow is already falling across portions of the southern and central Appalachians, including western North Carolina and southwest Virginia. A mix of rain and snow is forecast to move north throughout the day today and bring a few inches of snow from Washington D.C. to New York City. Farther northeast, upwards of 6 to 8 inches of snow could fall across far southern New England, including Cape Cod. Even though temperatures are right around the freezing mark for the more highly populated regions in the Northeast, snowfall intensity could be heavy at times and rapidly reduce visibility. This could potentially make travel difficult at times. Wintry precipiation will be quick to exit and come to an end across eastern Maine early Monday morning. Meanwhile, showers and isolated severe thunderstorms will be a concern across central and southern Florida today ahead of an approaching cold front. The Storm Prediction Center has issued a Marginal Risk for severe thunderstorms across the region due to the threat of damaging wind gusts and isolated tornadoes. Snowfall is also making headlines across the Northern Rockies and Central Plains as light-to-moderate snow impacts the region. A wave of low pressure is expected to move along a stationary front today across the Northern Rockies and enter the Central Plains by Monday. Continued snowy conditions will add an additional foot of snow across the mountainous terrain of northwest Wyoming, western Montana, and northern Idaho. Winter Storm Warnings and Winter Weather Advisories remain in effect for this area. Light snow is also expected to swing through portions of Nebraska today, before moving eastward across the Midwest and Ohio Valley on Monday. Although snowfall accumulations will be on the lighter side, temperatures well below freezing could make for slippery road conditions regardless. Speaking of cold temperatures, the Northern Plains and Midwest will be in for another day of brutal wind chills as arctic air remains locked across the region for the foreseeable future. High temperatures 20 to 30 degrees below normal will be found from the Canadian border to Oklahoma, extending as far east as northern Indiana and as far west as Montana through Tuesday. Many northern locations will struggle to see temperatures above zero, with wind chills as cold as -50 degrees. Wind Chill Warnings and Wind Chill Advisories have been issued for many of these locations. While this cold is definitely anomalous, only a few daily low temperature records are forecast to fall over the next few days.
