Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 356 PM EST Tue Nov 10 2020 Valid 00Z Wed Nov 11 2020 - 00Z Fri Nov 13 2020 ...Wintry precipitation across the upper Midwest and severe thunderstorms possible from the Midwest to the Great Lakes through tonight.. ...Another day of record breaking warmth expected for the eastern U.S. as heavy rain and some thunderstorms arrive on Wednesday and continue into parts of Thursday... ...Heavy mountain snow moving into the Pacific Northwest and northern Rockies... The anomalously warm weather across the eastern U.S. will continue for one more day as rain and some thunderstorms are expected to quickly move through the area Wednesday into Wednesday night. A few inches of rain is possible from the central Appalachians eastward into much of the Mid-Atlantic during the next couple of days which could lead to areas of flash flooding. The cold front responsible for this round of heavy rainfall will bring an end to the record warmth across the eastern U.S. by Thursday; but readings will remain above normal especially over the Southeast where the front is forecast to become stationary. Before the cold front reaches the East Coast, a low pressure system tracking up along the front towards the Great Lakes is currently spreading a swath of wintry precipitation across the upper Midwest where up to 6 inches of snow with locally higher amounts expected tonight into Wednesday morning as the storm moves further into Canada. Meanwhile, severe thunderstorms are possible from the Midwest to the Great Lakes through tonight as the trailing cold front sweeps across. The front will move across New England on Thursday where some showers and thunderstorms can be expected. Meanwhile, an active pattern over the northeastern Pacific will spread mountain snow and lower- elevation rain across the Pacific Northwest into the northern Rockies for the days to come. More than a foot of heavy snow could fall over the higher elevations of the Cascades and northern Rockies. The precipitation should begin to taper off on Thursday. However, the next surge of moisture is forecast to reach the Pacific Northwest coast later on Thursday. Last but not least, tropical storm Eta has been moving very slowly over the southeastern Gulf of Mexico today. The latest forecast from the National Hurricane Center (NHC) indicates that Eta could soon begin to track more quickly in the general direction of the northeastern Gulf of Mexico. Residents from the west coast of Florida into the Florida Panhandle should keep abreast of the latest forecasts of Eta from the NHC during the next couple of days.
