Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 347 PM EDT Thu Oct 29 2020 Valid 00Z Fri Oct 30 2020 - 00Z Sun Nov 01 2020 ...Heavy rain and gusty winds associated with Post-Tropical Cyclone Zeta to diminish overnight... ...Another round of showers is expected for the northern Mid-Atlantic early on Friday as well as light snowfall across the Interior Northeast and New England... ...A low pressure system will bring precipitation to the Pacific Northwest on Friday and gusty winds to the Northern Rockies/Plains through Saturday... After bringing heavy rain and damaging winds from the central Gulf Coast region to the Mid-Atlantic, Post-Tropical Cyclone Zeta is bolting off the East Coast this evening. Heavy rain and lingering gusty winds will still be possible from the Delmarva Peninsula to Cape Code tonight. Meanwhile, another system will be right on its heels and responsible for continued showers and a wintry mix across portions of the Interior Northeast and New England through midday Friday. This upper-level low following behind Zeta's remnants is the same system that left portions of Oklahoma and Texas cleaning up from heavy snow and an extremely impactful early-season ice storm a few days ago. This go-around will be a lot less impressive, as snowfall amounts across Upstate New York and New England are forecast to remain around 1 to 3 inches. At long last, much more tranquil, but still rather chilly weather will return to the eastern half of country just in time for Halloween as the entire storm complex exits into the Atlantic. Across the western U.S., a low pressure system will track onshore and inland across British Columbia on Friday. This will lead to relatively light precipitation for parts of Washington and Oregon. The center of the energetic system is then forecast to track throughout far southern Canada Friday, before arriving north of Lake Superior on Saturday night. A lack of moisture will result in little to no precipitation for the northern Rockies and northern Plains Friday into early Saturday as an associated cold front swings through. The biggest threat with the passing cold front will be gusty winds from the Northern Rockies to the Northern Plains. A High Wind Watch has been issued across portions of northwest Montana, as winds could gust up to 60 mph and make travel difficult for high profile vehicles. These winds will also lead to elevated fire weather across the Northern Rockies. Snell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
