Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 354 PM EDT Wed Apr 25 2018 Valid 00Z Thu Apr 26 2018 - 00Z Sat Apr 28 2018 ...Moderate to locally heavy rainfall to spread across the Deep South and into the Mid-Atlantic... Rainfall moving through the Northeast this afternoon will continue pressing northward, coming to an end on Thursday as the surface low and associated upper level system races northward into Canada. Behind this, another system is spreading rain and thunderstorms across the middle Mississippi Valley and into the Southern Plains, as an area of low pressure develops in the lower Mississippi Valley along the attendant cold front. As this surface low tracks east and eventually northeast Thursday and Friday, moderate to locally heavy rainfall with embedded thunderstorms will move across the Deep South and into the Mid-Atlantic. Behind this front, temperatures will be on the cooler side, with afternoon highs on Thursday and Friday near 10 degrees below normal across the Gulf Coast states and into parts of the Tennessee Valley. Elsewhere across the country, things should be mostly quiet as surface high pressure dominates across the central states. Some light and scattered rain showers may be possible along the northern part of the cold front as it moves eastward through the Great Lakes and eventually into the Northeast, and another round of precipitation looks to enter the west coast by the end of the work week ahead of a large upper level system out in the Pacific.
