Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 300 PM EST Sun Nov 08 2020 Valid 00Z Mon Nov 09 2020 - 00Z Wed Nov 11 2020 ...Heavy snow over parts of the Rocky Mountains and Northern Plains... ...Heavy rain and strong winds to impact southern Florida as Tropical Storm Eta approaches... ...Record or near record warmth continues over the Midwest and Northeast/Mid-Atlantic; record cold expected across California and Great Basin... Western U. S. storm moves into Canada as associated front moves to the Great Lakes to Western Gulf Coast by Tuesday evening. The storm will produce heavy snow and blizzard conditions across North-Central Montana into Monday as strong low pressure over North Dakota slowly lifts into the Canadian Prairies. An additional 8 or more inches of snow is likely through Monday morning across far North-Central Montana, including the city of Havre. Local storm total snow amounts in excess of 24 inches are likely. North to northwest winds of 20 to 30 mph with gusts of 40 to 60 mph will continue into tonight before easing into Monday. These blizzard conditions will continue to cause considerable blowing and drifting snow and reduce visibilities below one-quarter mile at times across central and northern Montana into Monday. Travel conditions will remain treacherous into Monday from the heavy snow and considerable blowing and drifting snow. Additionally, cold air will continue to filter into the western U.S. behind this system as high pressure builds over the Pacific Northwest. This cold airmass may lead to record breaking temperatures over parts of California and Nevada through Monday. While, record breaking heat is expected to expand over the Midwest, Northeast and Mid-Atlantic through Tuesday as high pressure along the east coast and the approaching low pressure system in the Plains are expected to pull warm air northward. High temperatures are likely to be between 30 and 40 degrees above average for parts of the Midwest and Northeast through Tuesday. The increased pressure gradient along the foothills of the Central Rockies, caused by the crossing of the previously mentioned area of low pressure, will generate strong wind leading to an Elevated Fire Risk for that area through Monday. Tropical Storm Eta moves closer to the Florida Peninsula as heavy rain, thunderstorms and strong wind continue over parts of the state. The WPC has issued a Moderate risk of excessive rainfall over the southeastern coast of the Florida Peninsula on Monday into Tuesday morning. The heavy rain associated with Tropical Storm Eta and easterly flow off the Atlantic will produce numerous areas of flash flooding and some of the flooding may be significant. In addition, many streams may flood, potentially affecting large rivers. 4 to 8 inches of rain is expected to fall across south Florida by Tuesday morning. Strong winds may produce coastal flooding and storm surge across southern Florida through Tuesday evening. Ziegenfelder Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
