DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0256 PM CDT SUN OCT 02 2011
VALID 022000Z - 031200Z
...NO SVR TSTM AREAS FORECAST...
...SYNOPSIS/FORECAST...
FEW CHANGES TO THE PRIOR CONVECTIVE OUTLOOK...CONSULT DISCUSSION
BELOW. A FEW STORMS COULD PRODUCE STRONG/GUSTY WINDS THIS AFTERNOON
WITHIN A MODEST BUOYANCY/WELL-MIXED THERMODYNAMIC ENVIRONMENT ACROSS
SOUTHERN/CENTRAL MT AND/OR NORTHERN WY. HOWEVER...ANY SUCH THREAT
SHOULD REMAIN RATHER LOCALIZED/MARGINAL IN NATURE.
..GUYER.. 10/02/2011
.PREV DISCUSSION... /ISSUED 1121 AM CDT SUN OCT 02 2011/
...SYNOPSIS/FCST...
DEEP-LAYER CYCLONE WILL REMAIN STATIONARY OVER THE MID-ATLC STATES
THROUGH TONIGHT. THE SFC CDFNT TIED TO THE SYSTEM HAS MOVED WELL E
OVER THE ATLC AND SWD INTO THE SRN GULF OF MEXICO...SHUNTING THE
PRIMARY LLVL THETA-E AXIS AWAY FROM LAND. NUMEROUS PV FILAMENTS
ROTATING AROUND THE UPR LOW WILL PERIODICALLY ENHANCE THE WARM
CONVEYOR BELT WRAPPING ACROSS CNTRL/NRN NEW ENGLAND. FCST SOUNDINGS
SHOW THAT MRGL MUCAPE WILL BE IN PLACE FOR PSBL ISOLD NON-SVR TSTMS
THIS AFTN/TONIGHT.
MEANWHILE...SCTD TSTMS WILL BE POSSIBLE TODAY AND TONIGHT
ACROSS MUCH OF THE INTERMOUNTAIN W. THESE WILL BE ASSOCIATED WITH A
LEADING BAND OF ASCENT DOWNSTREAM FROM ERN PAC TROUGH AND
SUBTROPICAL DISTURBANCES EJECTING ENE FROM NW MEX AND THE SWRN
STATES. SMALL HAIL AND GUSTY WINDS COULD OCCUR WITH THE
STORMS...PARTICULARLY OVER PARTS OF SWRN MT/WRN WY AMIDST STRONGER
DEEP LAYER SHEAR...BUT THE OVERALL SVR THREAT WILL REMAIN LOW OWING
TO MEAGER MOISTURE/INSTABILITY.
