720 FXUS01 KWBC 071936 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 335 PM EDT Tue Jul 07 2026 Valid 00Z Wed Jul 08 2026 - 00Z Fri Jul 10 2026 ...Strong to Severe Thunderstorms Expected from the Northern to Central Plains and Upper Midwest... ...Dangerous Heat Continues Across the Southeast and Southwest... ...Elevated to Critical Fire Weather Threat Across Portions of the West... A slow-moving frontal boundary extending across the northern Plains into the upper Midwest will be the focus for showers and thunderstorms developing later today and continuing into the overnight hours. Some of these storms are expected to become strong to severe, with large hail and damaging winds possible, especially from the Montana and Wyoming High Plains eastward into southern Minnesota. On Wednesday, the severe weather threat shifts farther south and east, with the greatest potential for severe thunderstorms extending from the upper Great Lakes southwestward into the central Plains. In addition to severe wind and hail, locally heavy rainfall may lead to areas of flash flooding. By Thursday, the front pushes east of the Great Lakes while lingering across the central Plains, supporting another round of showers and thunderstorms, including the potential for additional severe weather. Isolated severe thunderstorms are also possible along a stalled frontal boundary extending from Virginia and North Carolina westward into the Ohio and Tennessee Valleys. Across the Southeast, hot and humid conditions will persist and likely intensify through midweek. Above-normal temperatures, high humidity, and warm overnight lows will continue to increase the risk of heat-related illnesses, especially for those without access to adequate cooling or hydration. Temperatures will also remain above normal across portions of the Southwest, where Excessive Heat Warnings and Heat Advisories remain in effect across parts of Arizona and southern California. Mostly dry conditions are expected west of the Rockies. Dry fuels, low relative humidity, and gusty winds will support elevated to locally critical fire weather conditions across portions of the Cascades, Sierra Nevada, Great Basin, and Four Corners region through midweek.
