DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1010 AM CST TUE MAR 06 2012
VALID 061630Z - 071200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS...
A VIGOROUS UPPER TROUGH IS DIGGING S-SEWD FROM THE PAC NW TOWARDS
THE WRN GREAT BASIN...WITH AN ACCOMPANYING COLD FRONT MOVING ACROSS
SRN NV/CNTRL UT LATE THIS AFTERNOON. LARGE-SCALE ASCENT ACCOMPANYING
THE UPPER TROUGH SHOULD CONTINUE TO SUPPORT DEVELOPING SHOWERS
ALONG/AHEAD OF THE SEWD PROGRESSING COLD FRONT. HOWEVER...MEAGER
BUOYANCY OWING TO A COOL/DRY BOUNDARY LAYER SHOULD LEAD TO MINIMAL
POTENTIAL FOR LIGHTNING...ALTHOUGH A FEW ISOLATED STRIKES CANNOT BE
RULED OUT.
MEANWHILE...MODEST MOISTURE RETURN IS UNDERWAY OVER THE WRN/CNTRL
GULF COAST INTO THE SRN PLAINS...BUT WITH A MODIFIED AIR MASS
PRESENT OVER THE GULF...DEW POINTS ARE EXPECTED TO REMAIN IN THE 50S
F ACROSS N TX/OK. STRONG CAPPING ASSOCIATED WITH AN EML WILL
PRECLUDE ANY TSTM POTENTIAL OVER THE SRN/CNTRL PLAINS THIS PERIOD.
GRADUAL MOISTENING OVER S FL WILL OCCUR OVERNIGHT WITHIN A
PERSISTENT ELY LOW-LEVEL FLOW REGIME...BUT WEAK INSTABILITY /OWING
TO POOR MIDLEVEL LAPSE RATES/ WILL LIMIT LIGHTNING POTENTIAL.
