560 FXUS01 KWBC 070801 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 400 AM EDT Sat Jun 07 2025 Valid 12Z Sat Jun 07 2025 - 12Z Mon Jun 09 2025 ...Severe weather expected from the southern Plains to the Carolinas Saturday and across portions of the Central and Eastern U.S. on Sunday... ...Heavy showers capable of producing scattered flash flooding expected across portions of the Mid-South and southern New England Saturday... ...Significant heat continues across the Gulf Coast states and builds in the West through the weekend... Deep moisture and strong surface heating along a wavy frontal boundary will set the stage for numerous clusters of strong to severe thunderstorms from the southern Plains eastward to the Carolinas today. These clusters of storms will have the potential to produce swaths of damaging wind gusts, particularly from the Mid-South to the southern Appalachians. To highlight this threat, the Storm Prediction Center has issued a broad Slight Risk (level 2/5) that stretches from south-central Oklahoma and northeast Texas to the Carolinas. The Storm Prediction Center has also outlined a targeted Enhanced Risk (level 3/5), mainly for portions of eastern Oklahoma, central Arkansas, southern Tennessee, northern Mississippi, northern Alabama, and northern Georgia. While strong and damaging winds are the primary concerns from today`s storms, large hail and an isolated tornado or two cannot be ruled out. On Sunday, the risk of severe weather will generally remain across similar parts of the central and eastern U.S.; however, severe thunderstorms will be the most likely across southern Oklahoma, northern Texas, and the Ark-La-Tex late Sunday afternoon and evening. A few tornadoes, destructive wind gusts of 80-100 mph, and very large hail are the greatest threats with these storms. Accordingly, the Storm Prediction Center has issued an Enhanced Risk (level 3/5) to highlight this potential. In addition to severe weather hazards, the clusters of thunderstorms that develop along the wavy frontal boundary will also be efficient rainfall producers. Given plenty of moisture to work with and the potential for storms to repeatedly track over the same areas multiple times, scattered instances of flash flooding will be a concern, particularly across the Mid-South. Storms will also be capable of downpours across parts of southern New England as well. A Slight Risk (level 2/4) is forecast for both areas to account for this favorable heavy rainfall setup. On Sunday, similar to the greatest severe weather risk area, the highest flash flood threat will shift to the southern Plains, where additional complexes of drenching strong to severe thunderstorms are likely to move through. Dangerous heat will continue through the weekend across the Gulf Coast states where oppressive humidity ahead of a slow-moving frontal boundary will combine with temperatures in the mid to upper 90s to create a large area of Major to Extreme HeatRisk. Building heat will also be on the rise across interior portions of the West, especially the Pacific Northwest, where high temperatures nearing the triple digits will threaten records Sunday into Monday. Farther south across the lower desert valleys of the Southwest, high temperatures well into the 100s to 110s will make for a scorching weekend with little relief in sight.
