Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 216 PM EST Tue Dec 01 2020 Valid 00Z Wed Dec 02 2020 - 00Z Fri Dec 04 2020 ...Light to moderate snow continues overnight downwind of the Lower Great Lakes... ...Freeze Warnings in effect across much of the Southeast and northern Florida tonight... ...Heavy snow possible across portions of Kansas and Oklahoma late Wednesday into early Thursday... A powerful low pressure system that brought 2 to 4 inches of rain across New England and upwards of a foot of snow to northeast Ohio will be slow to exit the region. Light snow combined with lake-enhanced snow bands will produce an additional 2 to 4 inches of snow downwind from the Lower Great Lakes tonight. Any leftover wintry precipitation and gusty winds should wane by Thursday morning. The other area of impactful precipitation though the next couple of days is located from the central/southern Plains to the western/central Gulf Coast. An upper-level low pressure system situated over Oklahoma on Wednesday will lead to colder air filtering to the surface and the potential for heavy snow across southern Kansas and western Oklahoma. Snow is expected to begin Wednesday afternoon and last until Thursday morning. Widespread snowfall amounts of 4 to 8 inches are possible. Further southeast, heavy rain will be the biggest concern as a cold front interacts with an influx of moisture along the western Gulf Coast. Total rainfall amounts of 1 to 3 inches could cause isolated flooding concerns for areas that recently experienced heavy rain over this past weekend. By Thursday, the heavy rain threat shifts eastward to the central Gulf Coast. In coincidence with the first day of Meteorological Winter, much of the Southeast and even northern Florida will experience temperatures well below average for this time of year. Freeze warnings are in effect for tonight and Wednesday morning. Temperatures aren't expected to dip below freezing across central and southern Florida, but places such as Melbourne and Fort Myers could break record low temperatures on Wednesday. Finally, elevated to critical fire risk is expected across southern California through the workweek. This is due to offshore flow and increasingly windy conditions caused by a strong high pressure system building into the Great Basin and Rockies.
