SPC 0830Z Day 3 Outlook
Day 3 Convective Outlook NWS Storm Prediction Center Norman OK 0215 AM CST Tue Jan 07 2025 Valid 091200Z - 101200Z ...NO SEVERE THUNDERSTORM AREAS FORECAST... ...SUMMARY... Isolated thunderstorms may develop from Thursday into Thursday night from parts of central Texas to the Texas Coastal Plain and into far southwest Louisiana, but no severe threat is expected. ...DISCUSSION... At mid-levels, a positively tilted trough will move through the central and southwestern U.S. on Thursday, as southwest flow remains over much of the south-central and southeastern U.S. Ahead of the system across parts of the southern Plains, warm advection will take place in the mid-levels, with a very cold airmass at the lower levels. Forecast soundings Thursday morning suggest that MUCAPE could be in the 100 to 200 J/kg range in parts of Texas from the Hill Country to the Coastal Plain. This could be enough for isolated thunderstorm development. During the afternoon and evening, the chance for storms could increase some as a low to mid-level jet strengthens. The greatest chance for storms could be along the middle Texas coast overnight where a moist airmass is forecast to impinge upon the coast. Instability is expected to be too limited for a severe threat. ..Broyles.. 01/07/2025
