779 FXUS01 KWBC 011958 PMDSPD Short Range Forecast Discussion NWS Weather Prediction Center College Park MD 357 PM EDT Fri May 01 2026 Valid 00Z Sat May 02 2026 - 00Z Mon May 04 2026 ...Severe thunderstorms, including the threat for damaging winds and tornadoes, expected across northern Florida and adjacent portions of the Southeast on Saturday... ...Much below-average temperatures and widespread frost and freeze concerns will persist across the eastern and southern U.S. through this weekend... ...Record warmth possible across the Pacific northwest on Sunday... The heavy rainfall that battered Texas and the Lower Mississippi Valley through Friday will continue to wind down early tonight as the stalled frontal boundary finally sags southward into the Gulf, aided by a building surface high pressure. Attention then shifts to the Southeast, where a coastal low developing along the existing stationary boundary will become the dominant weather feature through the weekend. As an approaching upper-level trough helps nudge the front southward and eastward across the region Saturday, a robust surge of warm air from the Gulf will fuel rounds of showers and thunderstorms across northern Florida. Some storms could produce damaging wind gusts and isolated tornadoes, particularly across northeast Florida. The Storm Prediction Center has issued a slight risk (level 2/5) of severe thunderstorms for this region. The coastal low will continue to intensify as it tracks northeastward toward the Carolinas into Saturday evening, spreading rain into the Mid-Atlantic and coastal portions of the Northeast through early Sunday. Meanwhile, much below-average temperatures will remain locked in across much of the eastern and southern U.S. Widespread frost and freeze headlines are in effect across areas spanning the Great Lakes, the Ohio and Tennessee Valleys, the interior Northeast, and the central Plains. Some locations across the southern Rockies and Southern Plains will remain as much as 20 to 30 degrees below seasonal averages through the weekend. In sharp contrast, above-average temperatures will continue to build across the West. The Pacific Northwest will see temperatures surge well above normal this weekend, with record high temperatures possible on Sunday. Warm and dry conditions across the High Plains and interior West will also support elevated fire weather conditions, particularly Saturday into Sunday across portions of Nebraska and Wyoming where low relative humidity and gusty winds are expected.
