Subj : DAY2SVR: Nws Storm Prediction Center Norman Ok To : wx-storm@lists.illinois.edu From : COD Weather Processor Date : Wed Jul 30 2025 06:05:01 ACUS02 KWNS 300602 SWODY2 SPC AC 300601 Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 0101 AM CDT Wed Jul 30 2025 Valid 311200Z - 011200Z ....THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS OF THE COLORADO/WYOMING FRONT RANGE AND THE MID-ATLANTIC... ....SUMMARY... A few strong storms capable of large hail and damaging wind gusts are possible in portions of the Colorado/Wyoming Front Range and storms capable of damaging wind gusts are possible in the Mid-Atlantic. ....Synopsis... Upper-level ridging is forecast to strengthen across the central CONUS on Thursday. A large trough across southeast Canada will shift southeast across the Northeast with moderate mid-level flow overspreading the Mid-Atlantic. A surface cold front will extend from the Mid-Atlantic to the Southern Plains and then into the central High Plains. ....Central High Plains... Moderate to potentially strong instability is forecast to develop across the central High Plains with very steep mid-level lapse rates. Moderately strong mid/upper-level flow will provide ample shear. Therefore, as storms develop across the higher terrain and intensify as they encounter the greater instability east of the Mountains, they are also expected to become more organized, with the potential for some supercell structures. The steep mid-level lapse rates, relatively low freezing level, and favorably located buoyancy within the hail growth zone will all support the potential for isolated large hail. In addition, a deeply mixed boundary layer will also support some damaging wind gusts. ....Mid-Atlantic... Hot conditions are forecast ahead of a surface front in the Mid-Atlantic with temperatures in the mid 90s and dewpoints in the mid 60s. This will result in moderate to strong instability by early afternoon. Storms are expected to develop along the front by early afternoon and organize into a broken line. Isolated damaging wind gusts are possible from these storms during the afternoon to early evening due to a combination of a deeply mixed boundary layer and high moisture content (2+" PWAT). ...Bentley.. 07/30/2025 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
