SPC 0700Z Day 2 Outlook
Day 2 Convective Outlook NWS Storm Prediction Center Norman OK 1210 AM CST Tue Jan 20 2026 Valid 211200Z - 221200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorm are possible Wednesday and Wednesday night across portions of southeast Texas and Louisiana. ...Synopsis... Broad upper troughing will envelop much of the CONUS on Wednesday. An upper shortwave trough embedded within the large-scale trough will pivot east across the south-central to southeast states on Wednesday into early Thursday. As this occurs, some minor modified Gulf moisture will impinge on southeast TX into LA/MS ahead of a southward sagging cold front. This will support minor destabilization (MUCAPE around 100-300 J/kg) from southeast TX into LA. Cool temperatures aloft and modest large-scale ascent may be sufficient for isolated weak thunderstorm activity late Wednesday afternoon into the nighttime hours. Severe storms are not expected. ..Leitman.. 01/20/2026
