DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1130 AM CDT SAT SEP 04 2010
VALID 041630Z - 051200Z
...NO SVR TSTM AREAS FORECAST...
...WRN/CENTRAL MT AREA THIS AFTERNOON/EVENING...
A MIDLEVEL SHORTWAVE TROUGH OVER BC/WA WILL AMPLIFY SEWD OVER THE
NRN ROCKIES AS AN ASSOCIATED COLD FRONT MOVES SEWD ACROSS MT THIS
AFTERNOON THROUGH TONIGHT. THE MIDLEVEL TROUGH IS PRECEDED BY A
NARROW PLUME OF MIDLEVEL MOISTURE ACROSS NRN ID/WRN MT...AND
MODIFIED REGIONAL SOUNDINGS INDICATE THE POTENTIAL FOR AT LEAST WEAK
INSTABILITY AND DEEP INVERTED-V PROFILES THIS AFTERNOON AHEAD OF THE
FRONT. THESE PROFILES WILL SUPPORT HIGH-BASED THUNDERSTORMS WITH
THE POTENTIAL TO PRODUCE STRONG/ISOLATED DAMAGING GUSTS THIS
AFTERNOON/EVENING ACROSS WRN/CENTRAL MT AS MIDLEVEL FLOW INCREASES.
THE PRIMARY LIMITING FACTOR FOR A MORE ROBUST DAMAGING WIND THREAT
IS WEAK INSTABILITY.
...ELSEWHERE ACROSS THE CONUS...
DEEP DRYING IN THE WAKE OF A DEEP MIDLEVEL TROUGH OVER THE LOWER
GREAT LAKES/NEW ENGLAND...AND AN ASSOCIATED COLD FRONT MOVING OVER
THE NRN GULF OF MEXICO...WILL LIMIT THUNDERSTORM POTENTIAL ACROSS
THE MAJORITY OF THE CONUS. THE PRIMARY EXCEPTION WILL BE NEAR THE
SLOW-MOVING FRONT ACROSS S TX AND FL...WITHIN THE REMAINING TROPICAL
MOISTURE PLUME.
