Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 357 PM EDT Mon Jun 25 2018 Valid 00Z Tue Jun 26 2018 - 00Z Thu Jun 28 2018 ...Severe weather and heavy rainfall are possible for parts of the Plains, Mississippi Valley, and Midwest... ...Storms expected to continue for the Carolinas... ...Hot and dry for the Central Great Basin, Southwest, and into the Rockies and Plains... A low pressure system located over the Central Plains will move slowly eastward over the next few days. The low and its associated fronts will cause rain and thunderstorms for the Plains and Mississippi Valley on Monday, and into the Ohio Valley and Great Lakes region on Tuesday. Heavy rain is possible where storms could be slow-moving, and there is a slight risk of flash flooding in portions of the Plains to Mississippi Valley Monday night, and east into the Midwest on Tuesday. Additionally, severe thunderstorms are possible in the Middle Mississippi Valley on Monday night and Tuesday. As a surface low and stationary front linger over the Carolinas, more rounds of thunderstorms are likely there. Plenty of moisture and instability will lead to continued chances of heavy rain, flash flooding, and severe weather on Monday night in particular. Scattered showers and thunderstorms are forecast for the Tennessee Valley and into the Southern Appalachians. 1 to 2 inches of rain could fall in the higher elevations of the Appalachians as the mountains help enhance the rainfall. Temperature-wise, hot summer weather is expected to continue for the Southwest, Central Great Basin, and into the Central and Southern Rockies. On Tuesday and Wednesday, high temperatures will be 5-15 degrees above average in those areas. Temperatures are forecast to reach 100 degrees in the Central Plains on Wednesday after cooler temperatures on Monday. Cooler than normal temperatures will persist in the Carolinas on Tuesday with the clouds and rain, and the Mid-Atlantic to Northeast are expected to remain slightly below average as well.
