Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 244 PM EST Tue Jan 21 2020 Valid 00Z Wed Jan 22 2020 - 00Z Fri Jan 24 2020 ...Rain and higher elevation snow from the Pacific Northwest to the northern and central Rockies... ...Wintry mix to develop from portions of the Southern Plains to the Upper Great Lakes starting tonight... ...Freeze Warnings and Wind Chill Advisories are in effect across Florida... Unsettled weather will be found across much of the western U.S. this week as two upper level systems move in from the Pacific. A strong cold front is currently bringing coastal rain and mountain snow to the Pacific Northwest, with snow moving into interior sections of the West as the cold front advances eastward Wednesday. Not much of a break is expected for the Pacific Northwest as another system will approach on Wednesday, which will bring more rain/snow to the region. Two-day storm total snowfall amounts are expected to be highest in the Washington and Oregon Cascades, where one to two feet can be expected and even higher in the northern Washington Cascades. A weaker upper level system is tracking through the Southwest this evening with mountain snow and lower elevation rain. This system will eject out into the Southern Plains with mostly rain breaking out across Texas, but with a mixture of rain and snow found across Oklahoma tonight into Wednesday morning. Additional wintry weather will extend northward into the Missouri Valley along with light ice accumulations. Snow accumulations should stay on the light side, with two to four inches from northeast Kansas into the Upper Great Lakes through Thursday night. Cold weather will remain east of the Mississippi tonight, with low temperature departures running roughly 10 to 20 degrees below average. Thanks to high pressure across the Mid-Atlantic and a potent low pressure system to the east, Florida will be particularly cold. Wind chill values in the teens and 20s will be felt across central and northern portions of the state tonight into Wednesday morning. Some moderation will occur on Wednesday along and west of the Appalachian Mountains. However, below average temperatures will remain across eastern Texas/Oklahoma into the Lower Mississippi Valley in association with the storm system approaching from the west mentioned earlier. However, up north a warmer trend is anticipated from the northern High Plains spreading east into the Great Lakes region for Wednesday. High temperature departures for Wednesday will run a good 10 to 20 degrees above average from eastern Montana and Wyoming into and across the Upper Mississippi Valley.
