Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 320 PM EDT Wed May 29 2019 Valid 00Z Thu May 30 2019 - 00Z Sat Jun 01 2019 ...Record heat to continue across portions of the Southeast... ...Strong to severe storms and flooding rains for parts of the Plains, mid Mississippi and Ohio valleys and the Mid-Atlantic region... Well-above normal temperatures are forecast to continue today and Thursday for portions of the Mid-Atlantic and Southeast. Daytime temperatures reaching into the upper 90s to low 100s are expected to set several new records from the Carolinas to northern Florida. In addition to the heat, dry and windy conditions are raising fire weather concerns as well, with a Red Flag Warning in effect through Thursday for the South Carolina Midlands. On Friday, a cold front approaching from the east is forecast to bring showers and storms with some relief from the heat. This front currently extends from the lower Missouri valley back into the southern Plains. Very moist and unstable air ahead of the front is supporting the development of widespread showers and storms this afternoon from northern Texas to southern Missouri. It is likely that some storms will become severe, with tornado and severe thunderstorm watches now being raised across the region. The Storm Prediction Center is highlighting the area with an Enhanced Risk area for severe weather through tonight. In addition to the severe thunderstorm risk, excessive rainfall is a significant concern as well. Heavy rains falling on saturated soils will result in rapid runoff and exacerbate the flooding conditions that are already occurring across the area. The Weather Prediction Center is maintaining a Moderate Risk for excessive through the overnight hours from northeastern Texas to the Ozark region. Meanwhile, a slow moving boundary extending from the northern Mid-Atlantic region back through the Ohio valley is once again providing the focus for developing strong to severe storms. Here also severe thunderstorm watches have been raised, as storms are expected to continue in the evening hours. Additional storms can be expected on Thursday as the front sinks slowly south across the northern Mid-Atlantic, central Appalachians and the Ohio valley. Father west, average to below-normal daytime temperatures are forecast to continue into the latter part of the week across much of Southwest, Great Basin, central and southern Rockies and High Plains. Above normal temperatures are expected to continue from the Northwest to the northern Plains. Pereira Graphics available at www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
