Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 357 PM EDT Tue Apr 25 2017 Valid 00Z Wed Apr 26 2017 - 00Z Fri Apr 28 2017 ...Heavy rain and storms for the central U.S., and snow for the Rocky Mountains... A low pressure system situated near the Mid-Atlantic coast will continue to weaken over the next two days as it heads to the Northeast U.S., but still will be capable of producing areas of moderate to heavy rain from the northern Mid-Atlantic to New England. After this system departs, a major warming trend is expected for the end of the week, with highs well into the 80s for many areas, along with noticeable levels of humidity. 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 Thursday, 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 www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
