Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 252 AM EST Fri Nov 15 2019 Valid 12Z Fri Nov 15 2019 - 12Z Sun Nov 17 2019 ...Temperatures across the eastern U.S. will recover during the next couple of days but they will remain below average... ...Rain along the Gulf Coast will head to the Southeast by the weekend with increasing winds... ...Good chance of snows across the Great Lakes through Friday while rain moves onshore into the Pacific Northwest... Scattered to widespread rain is expected to spread from the eastern Gulf Coast/Southeast northward into the Carolinas and Mid-Atlantic over the next couple of days. Strong moisture convergence will setup along a frontal boundary where a surface low quickly strengthens off the East Coast. This will allow focused moderate to heavy, longer duration rainfall, as well as blustery winds along the coast-- especially from South Carolina to the Del-Mar-VA region. At this time, this poses a Marginal Risk for excessive rainfall. Concern for high surf/waves and coastal flooding may also increase with the proximity of the system to the coast. High pressure tracking from the Plains into the Ohio Valley in the wake of a cold front will keep cooler, yet not as frigid, air over portions of the East Coast. Many locations will have below average temperatures. Multiple weak cold fronts will pass through the Great Lakes region into the weekend, which will keep light snow a possibility across the Great Lakes and interior portions of the Northeast. Behind the front, a strong high pressure associated with deep cold Arctic air will provide another chance of temps 15-20 degrees below on Saturday for extreme northern New York, Vermont and New Hampshire. Showers over the Pacific Northwest will transition to high elevation snow across portions of Idaho and Montana Friday in Saturday as disturbance crosses the Pacific Northwest and Northern Rockies into southern Canada. This will bring snow along with a wintry mix to spread into the Upper Midwest and Great Lakes by Saturday evening. Campbell Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
