Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 357 PM EDT Sat Apr 01 2017 Valid 00Z Sun Apr 02 2017 - 00Z Tue Apr 04 2017 ...Threats of severe weather and flash flooding will impact areas from the southern Plains to the Southeast... ...Snow will taper off New England by Sunday... ...An increase in snow will occur through the Rockies... The deepening low pressure system that is beginning to move off the New England coast will continue bringing snow through most of today and into Saturday night. By Sunday morning, the low will move farther away from the coast and snow will completely taper off. A front moving across West Texas will be the primary driver for both the severe weather and flash flooding in the southern U.S. over the next few days. The front currently moving toward central Texas will combine with a warm front lifting north from the Gulf of Mexico by late Saturday. This will bring plenty of moisture and instability across Texas. A slight risk for severe weather and flash flooding will be present along the Big Bend northward toward the Red River Valley through Saturday night as the front pushes eastward. By Sunday, the warm front will continue to lift north as the cold front moves toward southeast Texas. The Storm Prediction Center has most of southeast Texas, including Houston, in addition to the Lower Mississippi Valley in a moderate risk of severe weather (please check www.spc.ncep.noaa.gov for more information). There will also be a slight risk for flash flooding across these areas. The front will continue its eastward trek across the Southeast through Sunday night and into Monday--and once again brings with it the risk of severe weather and flash flooding. A cold front that will drop through the Intermountain West and Rockies will bring an increase of precipitation across the area beginning on Sunday. Higher elevation snow can be expected on Sunday mostly in the northern Rockies. As the front progresses southward on Monday, precipitation will occur throughout the Central Great Basin and Central Rockies--including with higher elevation snow.
