   ACUS03 KWNS 240729 SWODY3 SPC AC 240729 Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0229 AM CDT Sat May 24 2025 Valid 261200Z - 271200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF THE SOUTHERN PLAINS... ...SUMMARY... A severe threat is expected on Monday across parts of the southern Plains, with large hail and wind damage as the primary threats. Marginally severe storms will also be possible outside the Slight Risk area from the southern Plains into the Southeast. ...Southern Plains... At mid-levels, a shortwave trough is forecast to move into the southern and central High Plains on Monday, as southwest flow persists over much of the south-central U.S. Early in the day, warm-advection-related convection is expected to be ongoing at the start of the period over parts of the southern Plains. Morning storms will hamper destabilization in some areas, especially further north into parts of Oklahoma and the Ozarks. The effective cold front could be located near the Red River extending eastward into the Ark-La-Tex. To the south, model forecasts suggest that strong instability will develop by midday. As surface heating takes place, and low-level convergence increases near the front, scattered thunderstorm initiation is expected in the afternoon. Model forecasts suggest that storm coverage will increase in the afternoon, developing southward across parts of north and central Texas. The ECMWF has been relatively consistent with scenario from run to run. Forecast soundings from the ECMWF at 00Z/Monday within parts of this unstable airmass have 0-6 km shear above 30 knots with 700-500 mb lapse rates near 8 C/km. Since deep-layer shear is forecast to be marginal for supercells, a mixed mode would be expected. Near instability maxima, supercells could form and have a large hail threat. In other areas where instability is lessened, short line segments with severe gusts would be favored. ...Southeast... A west-southwesterly mid-level flow pattern is expected over the Southeast. At the surface, a moist airmass is forecast from the lower Mississippi Valley eastward to the southern Atlantic Seaboard. As surface temperatures warm across this airmass during the day, moderate instability is expected to develop in some areas. Thunderstorms appear likely to form along pre-existing boundaries and along focused zones of low-level convergence. Although deep-layer shear is forecast to be relatively weak, low-level lapse rates will likely become steep in areas that heat up the most. This should support marginally severe wind gusts with multicells that become locally intense. ..Broyles.. 05/24/2025 $$ |
