Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 231 PM EDT Mon Apr 24 2017 Valid 00Z Tue Apr 25 2017 - 00Z Thu Apr 27 2017 ...Heavy rain across the eastern U.S. and storms across the central U.S. through midweek... A complex low pressure system situated near the Southeast coast will cause widespread heavy rain across the Carolinas and into Virginia through early Tuesday. Another low tracking northward from the Bahamas will merge with this system, supplying additional moisture and thus heavier rainfall. This surface low and its accompanying upper low is forecast to weaken some as it heads to the Northeast U.S. by midweek, but still will be capable of producing areas of heavy rain from the Mid-Atlantic to New England. Flash flooding will be possible where training convection occurs, especially over eastern North Carolina going through early Tuesday. Across the central U.S., a well-defined frontal zone is expected to become established from the Upper Midwest to Texas. Two surface lows are expected along this boundary, with one over the Upper Midwest, and the other over the southern Plains. Multiple rounds of severe weather are possible near the front and ahead of the dryline over western Texas. Winter weather is still upon us for the higher elevations of the northwestern U.S. through Wednesday, including the Cascades and the northern/central Rockies. A Pacific front moving onshore Tuesday night will likely produce an enhanced band of precipitation with it across the Pacific Northwest. Temperatures will continue to be below normal across the north-central part of the nation. Hamrick Graphics available at
