Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 221 PM EDT Mon Apr 29 2019 Valid 00Z Tue Apr 30 2019 - 00Z Thu May 02 2019 ...Active weather pattern continues across the middle of the country... ...Severe thunderstorms and flash flooding possible in the Central U.S. through Wednesday... The weather pattern will remain unsettled from the Upper Midwest and Plains into the central Rockies. A front stretching across the same region will move very little in the next few days. Multiple waves of low pressure are expected along this front and will result in areas of enhanced precipitation. The heaviest rain is likely from Oklahoma to Michigan, with some locations receiving several inches of rain by Wednesday afternoon. There will also be an increased threat of flash flooding in this same corridor, where multiple rounds of thunderstorms are expected. These waves of thunderstorms may produce some severe weather, particularly over the southern Plains -- North Texas, Oklahoma and Eastern Kansas -- and into the Ozarks of Missouri and Arkansas. Further west in the Central Rockies, heavy snow is expected with the potential for over 1 foot of accumulation in the higher mountain ranges. The ranges most likely to receive heavy snowfall are in Western Colorado, Wyoming, and central Utah. Some snow is also likely across the western High Plains from western Nebraska to eastern Montana. To the north and west of the stationary front, temperatures will remain below average across the northern tier of the nation and Intermountain West through the beginning of the week. The greatest temperature departures from average will be across the northern High Plains. Warmer than average readings are expected south of the front, particularly in the Southeast.
