Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 359 AM EDT Mon Sep 17 2018 Valid 12Z Mon Sep 17 2018 - 12Z Wed Sep 19 2018 ...The threat of flash flooding will shift to the central Appalachians, Mid-Atlantic and Northeast today... ...Significant river flooding will continue across North Carolina... As Florence continues to weaken, it will move north today toward the Mid-Atlantic today. Moderate to rainfall is expected to develop across the portions of the northern Mid-Atlantic and Northeast today. However, ongoing heavy rainfall across the mountains in Virginia and West Virginia could lead to flash flooding. Landslides will also continue to be a hazard for the central Appalachians. Additionally, moderate rainfall will also linger across central and western North Carolina. Consequently, the central Appalachians northward into the northern Mid-Atlantic and Northeast are under a moderate risk of flash flooding with a slight risk of flash flooding for portions of western and central North Carolina. Significant river flooding is still ongoing across parts of central and eastern North Carolina. By Tuesday, the heavy rain along with the remnants of Florence will spread from the Northeast to coastal New England. Some of this precipitation could produce flash flooding; thus, a slight risk of excessive rainfall has been issued for portions of New England. By Wednesday, all precipitation will finally exit off the East Coast. Farther west, a slow moving frontal boundary will provide focus for showers and thunderstorms to develop across the northern Plains on Monday afternoon and will move into the Upper Midwest late Monday night into Tuesday. The boundary is expected to stall, and these storms will also linger through Wednesday across the northern Plains and Upper Midwest. A slight risk of flash flooding will be possible for parts of these regions through the short term period along with a marginal risk for severe weather today and Tuesday.
