Day 3 Convective Outlook
NWS Storm Prediction Center Norman OK
1255 AM CST Tue Dec 05 2017
Valid 071200Z - 081200Z
...NO THUNDERSTORM AREAS FORECAST...
No thunderstorms are expected on Thursday.
Strongly amplified upper pattern, characterized by western CONUS
ridging and central/eastern CONUS troughing, will gradually shift
eastward throughout the period, while maintaining significant
amplification. At the surface, expansive high pressure will remain
largely in place, extending from the Pacific Northwest
eastward/southeastward to the MS Valley. Some showers are possible
within the warm-air advection north of a decaying cold front, from
south TX into southern GA and northern FL. However, limited
instability and elevated nature to these showers will likely inhibit
thunderstorm development. No thunderstorm activity is expected
elsewhere across the CONUS.
