Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 256 AM EST Thu Feb 21 2019 Valid 12Z Thu Feb 21 2019 - 12Z Sat Feb 23 2019 ...Heavy rain continues across the Southeast through Friday and heavy snow expected for the southern Rockies... Wet weather is forecast to continue through the end of the week across much of the Gulf Coast region and the Southeast U.S. given the presence of a stationary front that remains anchored in place. Multiple rounds of showers and thunderstorms are expected to progress from southwest to northeast and result in 2 to locally 4 inches of rain in a corridor from Louisiana to Kentucky, and flood watches remain in effect for many of these areas. The overall weather pattern is quite similar to the past couple of days except that temperatures are a little warmer with much less expected in terms of any wintry weather on the north side of the precipitation. Ongoing river flooding will also continue to be problematic. Areas of dense fog over parts of the Deep South are expected Thursday morning as higher humidity advects northward from the Gulf of Mexico. Temperatures will continue to be below average across much of the western U.S. and across the northern plains as a broad upper level trough continues to govern the weather pattern. A strong upper level system is forecast to slowly churn across the Southwest on Thursday and then exit across the southern plains by Friday evening. This will bring very heavy snow to the higher elevations of the Southwest and Southern Rockies, with the Mogollon Rim of Arizona and the San Juan mountains of Colorado getting hammered with 1 to 3 feet of snow! Additional snowfall is expected from eastern Colorado to Minnesota along a developing front, but these amounts are expected to be light to moderate compared to the event over the southern Rockies. D.
