   Day 2 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   1158 PM CST Tue Dec 05 2017

   Valid 071200Z - 081200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   No thunderstorms are expected on Thursday.

   ...Synopsis...
   A deep upper trough will cover much of the CONUS at the beginning of
   the period with upper ridging in place along the West Coast. This
   highly amplified pattern will persist, and perhaps deepen, as it
   gradually shifts eastward during the day. By 12Z Friday, expansive
   upper ridging will likely be centered over northern CA/southern OR
   and positively tilted upper troughing will extend from the Hudson
   Bay into northern Mexico. 

   At the surface, strong high pressure will expand
   eastward/southeastward into the middle/lower MS Valley and
   Southeast, helping the dry, cold, and stable continental airmass
   remain in control of the sensible weather across the majority of the
   CONUS. The only exception is from south TX northeastward into the
   Carolina where some showers are possible within the warm-air
   advection zone north of the decaying front. However, moist profiles
   and resulting poor lapse rates will temper instability, keeping
   lightning potential very low.
