Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 439 AM EDT Mon Jul 29 2013 Valid 12Z Mon Jul 29 2013 - 12Z Wed Jul 31 2013 ...Storms carrying a threat for flash flooding and severe weather are expected to move through Kansas and Missouri... Conditions should continue to dry out over the Northeast and Mid-Atlantic states on Monday as a cold front exits off the Eastern Seaboard. The same air-mass that brought record breaking low temperatures to portions of the Midwest and Ohio Valley this weekend will fill in behind the front...lowering dew points and making for a comfortable start to the work week. The southern portion of the boundary will be slower to push off the coast...leading to additional days of scattered showers and thunderstorms across Florida and up into the Carolinas. The tail end of the boundary departing the Atlantic coast is expected to stall out and raise havoc across the Central Plains and Middle Mississippi Valley the next few days. Moisture pumping northward over the boundary will continue to fuel an organized area of storms that has already broken out over Kansas. These storms...which will carry a threat of both flash flooding and severe weather...should slowly progress eastward over Missouri on Monday and eventually into the Ohio Valley on Tuesday. Elsewhere across the Nation...a cold front crossing the northern tier will trigger some scattered convection as it pushes through the Dakotas and Minnesota. Another day of late afternoon/early evening thunderstorms are expected across the Central Great Basin and Rockies on Monday...but then storms should become less numerous on Tuesday.
