SPC 1730Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1030 AM CST Fri Nov 26 2021 Valid 271200Z - 281200Z ...NO THUNDERSTORM AREAS FORECAST... ...SUMMARY... Thunderstorms are not forecast across the contiguous United States on Saturday. ...Synopsis and Discussion... Within the southern stream of the mid-level westerlies, a shortwave trough is forecast to move eastward from north-central Mexico across much of TX on Saturday. Some modest low/mid-level moisture should return northward across parts of TX ahead of this feature, with a broad swath of light to moderate precipitation likely occurring associated with the ascent preceding the upper trough/low. However, more substantial low-level moisture is expected to remain confined to the western Gulf of Mexico to the south of a remnant front. Consensus of latest guidance suggests that any elevated instability that may develop with the light to moderate precipitation over TX should remain too shallow/meager to support a meaningful chance of lightning flashes. Accordingly, thunderstorm chances are being held at less than 10% for Saturday across the CONUS. ..Gleason.. 11/26/2021 Read more LIVE: spc.noaa.gov
