Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 331 AM EDT Wed May 1 2019 Valid 12Z Wed May 1 2019 - 12Z Fri May 3 2019 ...Active weather pattern continues across the Plains and the Midwest... The weather pattern will continue to be unsettled across much of the southern Plains and extending northeastward across the Midwest and Ohio Valley through the middle of the week. A slow moving frontal boundary will persist from the Great Lakes region to Texas, and multiple waves of low pressure are expected along this front and will result in areas of enhanced rainfall. The heaviest rain is likely from central Texas to southern Illinois, with widespread 1 to 3 inch amounts expected. There is an increased threat of flash flooding across northern Texas and extending over the ArkLaTex region, where multiple rounds of thunderstorms are expected, and WPC has a Moderate Risk of excessive rainfall near the Greater Dallas/Fort Worth metro area on Wednesday. The threat of severe weather is also present across this same general area based on SPC forecasts, with intense storms likely developing in the vicinity of the front and near the surface low. The heavy snow that has been ongoing across the Rockies is expected to decrease in coverage and intensity on Wednesday as the forcing for ascent weakens along with drier air. Temperatures will continue to remain below average across the northern tier of the nation through the middle of the week, with a slow moderating trend by the end of the week. Warmer than normal readings are expected from Texas to the Southeast U.S. and Mid-Atlantic region, which will remain south of the frontal boundaries. Widespread highs in the 80s to low 90s are possible during the time, making it feel more like late June for many areas. D. Hamrick Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
