Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 338 AM EDT Thu May 30 2024 Valid 12Z Thu May 30 2024 - 12Z Sat Jun 01 2024 ...More active weather across the mid sections of the nation, with additional rounds of thunderstorms, heavy rains, flash flooding and severe weather... ...Heat to continue across the Southwest to South Texas and much of Florida, while building across the inland valleys of California... ...Cooler than average temperatures for the Plains and large portions of the eastern U.S. through early this weekend... A tumultuous weather pattern sparking several rounds of robust thunderstorms is set to continue throughout much of the central and south-central United States. The atmospheric ingredients in play for the next serving of severe weather include an upper trough with embedded shortwaves crossing the Rockies today, multiple frontal boundaries draped across the Great Plains, and ample atmospheric moisture content lifting northward from the western Gulf of Mexico. Additionally, a reemerging dryline over the southern High Plains will help spark strong storms this afternoon that are forecast to progress eastward tonight over the southern Plains. These thunderstorms may contain large hail and damaging wind gusts, with the locations most likely impacted including the Texas Panhandle and parts of west Texas. A broader threat for isolated severe weather stretches throughout a majority of the central and southern Plains. Intense rainfall rates are also possible and can lead to flash flooding where storm motions are slow. Currently, the scattered flash flood threat includes much of the central/southern Plains and ArkLaTex region. The active weather and clusters of redeveloping thunderstorms are then forecast to gradually slide eastward on Friday as an area of low pressure pushes across the Red River Valley of the South. Additional chances for damaging wind gusts and large hail exists across central and eastern Texas, as well as into the Lower Mississippi Valley. Flash flooding also remains a concern for the last day of May across the southern Plains and Lower Mississippi Valley. Wet weather is anticipated to expand to start the weekend, but with less focus for severe weather as thunderstorm chances stretch from the Ohio/Tennessee valleys to the Great Plains. Storminess over the central U.S. will keep high temperatures below average to end the week, while a potent high pressure system over the Lower Great Lakes and Ohio Valley also offers refreshing afternoon temperatures in the 70s for large sections of the Eastern United States. Summer heat will be continue to be found across the Southwest and Southern Tier. Muggy highs into the mid-90s are forecast across the central/southern Florida Peninsula until a cold front enters on Saturday and offers some much needed relief in the form of persistent northeasterly flow. Upper 90s and low 100s are anticipated to stretch from the Southwest to far western and southern Texas through the weekend. Heat will actually build further north into the Great Basin and interior California valleys as well, but not quite warm enough to approach daily records. If spending time outdoors in these regions, be sure to follow proper heat safety. Snell Graphics available at https://www.wpc.ncep.noaa.gov/basicwx/basicwx_ndfd.php
