   DAY 2 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1230 AM CST SUN JAN 25 2015

   VALID 261200Z - 271200Z

   ...NO TSTM AREAS FORECAST...

   ...SUMMARY...
   THE RISK FOR THUNDERSTORMS APPEARS NEGLIGIBLE ON MONDAY AND MONDAY
   NIGHT.

   ...SYNOPSIS...
   A SHORTWAVE TROUGH WILL EXIT THE S ATLANTIC COAST MON MORNING
   WHILE AN UPSTREAM IMPULSE RAPIDLY PROGRESSES FROM THE UPPER MS
   VALLEY TOWARDS THE SRN APPALACHIANS. THIS WILL EFFECTIVELY YIELD A
   BROAD UPPER TROUGH OVER THE EAST...AS A HIGHLY AMPLIFIED RIDGE
   BECOMES CENTERED FROM THE SRN HIGH PLAINS TO THE NORTHWEST. CLOSED
   MID-LEVEL LOW W OF BAJA CA SHOULD SLOWLY FILL AS IT APPROACHES THE
   SRN CA COAST MON NIGHT.

   ...DISCUSSION...
   SOME MODIFICATION TO THE CONTINENTAL AIR MASS OVER THE NRN GULF
   /CURRENTLY CHARACTERIZED BY 40S SURFACE DEW POINTS/ WILL OCCUR IN
   ASSOCIATION WITH THE LEAD SHORTWAVE TROUGH SHIFTING OFF THE S
   ATLANTIC COAST. ALTHOUGH SHOWERS ARE POSSIBLE OVER LAND...SUFFICIENT
   BUOYANCY FOR TSTMS SHOULD BE CONFINED TO THE GULF STREAM. IN THE
   SOUTHWEST...MID-LEVEL LAPSE RATES WILL STEEPEN ACROSS SRN CA MON
   NIGHT JUST AHEAD OF THE MID-LEVEL LOW. HOWEVER...BUOYANCY SHOULD
   REMAIN MINIMAL WITH MUCAPE AOB 100 J/KG...PRECLUDING TSTM
   PROBABILITIES AOA 10 PERCENT.
