Valid 12Z Wed Feb 17 2021–12Z Fri Feb 19 2021

The dangerous Arctic blast over the Nation’s Heartland begins to moderate in the coming days. While that means the number of record cold maximum and minimum temperatures will not be as common (the bulk of which occurring in the South Central U.S.), temperatures themselves will still remain 20 to 35 degrees below normal throughout the Plains, Mississippi Valley, and lower Great Lakes. orning lows in the single digits or below zero look to continue both today and Thursday in parts of the Great Plains. Bitterly cold temperatures have pushed east into the Mid-Atlantic and Northeast ahead of the impending winter storm that arrives Thursday morning.

High temperatures will struggle to eclipse the freezing mark both today and Thursday in these regions. The warmest location in the country is the state of Florida where highs look to soar into the 80s on Thursday. https://www.wpc.ncep.noaa.gov/discussions/hpcdiscussions.php?disc=pmdspd

Bitter cold has pushed east into the Mid-Atlantic and Northeast ahead of the impending winter storm that arrives Thursday morning. High temperatures will struggle to eclipse the freezing mark both today and Thursday in these regions.

Out West, after a day of tranquil weather on Wednesday, a Pacific storm system ushers in another round of valley/coastal rain and mountain snow on Thursday. Locally heavy rainfall is possible in far northwestern California and far southwestern Oregon on Thursday. Meanwhile, the Cascades are likely to receive another foot of snow with heavy snow working its way into the northern Rockies Thursday night and continuing into Friday morning.
