726 FXUS01 KWBC 291815 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 215 PM EDT Wed May 29 2024 Valid 00Z Thu May 30 2024 - 00Z 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 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... No let up to the recent very active weather pattern across the mid section of the nation over the next few days. Heavy rains, flash flooding and severe weather that has been focusing across the Southern Plains over the past two days will be re-focusing farther to the north Wednesday evening across the Northern to Central High Plains ahead of a strong cold front pushing eastward across this area. This thunderstorm activity has the potential to produce severe weather, heavy rains and isolated flash flooding overnight into early Thursday across the Northern to Central High Plains as the thunderstorms push eastward. By late Thursday afternoon, strong southern stream mid to upper level disturbances are expected to push into the Southern Plains, initiating another round of active and potentially impactful thunderstorms. Additional heavy rains, flash flooding and severe weather are possible across a large portion of the Southern Plains from North Texas, across much of Oklahoma, Kansas, southern Nebraska and eastern Colorado. No big changes expected to the recent heat across Southwest to South Texas and across much of Florida, with much above average temperatures expected to persist across these regions over the next few days. There will continue to be the potential for record high afternoon temperatures across portions of central to Southwest Florida Thursday and Friday along with record high morning low temperatures across the Florida Keys Thursday and Friday mornings. Hot temperatures also expected to be expanding across the interior valleys of California over the next two days with high temperatures reaching the middle to upper 90s. These temperatures, however, will remain below record values for these dates. In contrast to the above mentioned hot temperatures, cooler than average temperatures are forecast across much of the Plains due to the ongoing wet weather and cloud cover. Cooler than average temperatures are also expected to persist large portions of the eastern U.S. from the Lower Lakes, through the Appalachians, Mid-Atlantic and Southeast.
