   DAY 2 CONVECTIVE OUTLOOK  
   NWS STORM PREDICTION CENTER NORMAN OK
   1235 AM CDT THU OCT 30 2014

   VALID 311200Z - 011200Z

   ...NO SVR TSTM AREAS FORECAST...

   ...SUMMARY...
   ISOLATED THUNDERSTORMS WILL BE POSSIBLE ACROSS PARTS OF THE FOUR
   CORNERS AND PACIFIC COAST STATES...ALONG WITH SOUTH
   TEXAS...SOUTHEAST FLORIDA...THE CAROLINAS...AND GREAT LAKES.

   ...DISCUSSION...
   A HIGHLY AMPLIFIED UPPER-LEVEL PATTERN IS ANTICIPATED ON FRI WITH
   BROAD TROUGHS IN THE EAST AND WEST...AND A RIDGE SHIFTING FROM THE
   ROCKIES TO THE GREAT PLAINS. A POTENT SHORTWAVE IMPULSE WILL DIVE SE
   FROM THE UPPER GREAT LAKES TO THE SC AREA BY 12Z/SAT. COLD MID-LEVEL
   TEMPERATURES MAY SUPPORT SPORADIC LIGHTNING STRIKES AMIDST MINIMAL
   BUOYANCY OVER PARTS OF THE GREAT LAKES AND THE CAROLINAS. 

   A STOUT SURFACE ANTICYCLONE WILL BUILD INTO THE UPPER MIDWEST IN THE
   WAKE OF THE POWERFUL SHORTWAVE IMPULSE. THIS WILL YIELD A
   STABILIZING CP AIR MASS ENVELOPING THE GULF COAST STATES. DEEP S TX
   AND FAR SE FL WILL HAVE EARLY-PERIOD TSTM POTENTIAL AHEAD OF THIS
   INTRUSION.

   IN THE WEST...A PLUME OF RICHER 700-MB DEW POINTS WILL BE DRAWN N
   FROM CHIHUAHUA/SONORA DOWNSTREAM OF THE UPPER-LEVEL TROUGH ENTERING
   THE PACIFIC COAST STATES. MEAGER BUOYANCY WITH STEEP MID-LEVEL LAPSE
   RATES SHOULD SUPPORT A FEW STORMS. IN CLOSER PROXIMITY TO THE
   TROUGH...SCANT BUOYANCY MIGHT RESULT IN SPORADIC LIGHTNING STRIKES
   WITHIN PREDOMINANT SHOWERY CONVECTION. FAST MID-LEVEL FLOW AND COOL
   THERMODYNAMIC PROFILES COULD AID IN SMALL HAIL WITHIN THE STRONGEST
   UPDRAFTS.
