DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1141 AM CDT WED MAR 13 2013
VALID 141200Z - 151200Z
...NO TSTM AREAS FORECAST...
...SYNOPSIS/FORECAST...
NEGLIGIBLE TSTM POTENTIAL ACROSS MUCH OF THE CONUS DURING THE
PERIOD. THE LONE EXCEPTION WILL BE FROM PARTS OF IL TO ERN TN DURING
THE DAY ON THU IN ASSOCIATION WITH A CLIPPER-TYPE IMPULSE
PROGRESSING SEWD FROM THE UPPER MS VALLEY TO THE SRN APPALACHIANS.
HERE...SOME 09Z SREF MEMBERS DEPICT SCANT ELEVATED BUOYANCY WHICH
COULD YIELD A FEW LIGHTNING STRIKES WITHIN THE ZONE OF STRONGEST
ISENTROPIC LIFT. FORECAST SOUNDINGS SUGGEST PW VALUES NEAR 0.6 IN
WILL BE NECESSARY FOR THIS TO OCCUR...WHICH CORRESPONDS TO THE SREF
MEAN PW 36-H FORECAST. HOWEVER...THE 3-H SREF MEAN PW WAS TOO HIGH
COMPARED TO RAOBS/GPS PW DATA AT 12Z THIS MORNING OVER THE CNTRL/SRN
PLAINS. GIVEN WLY LOW-LEVEL TRAJECTORIES AHEAD OF THE SEWD-TRACKING
MID-LEVEL IMPULSE AND CURRENT PW VALUES AOB A HALF INCH...MOISTURE
RETURN WILL PROBABLY REMAIN INSUFFICIENT TO WARRANT AN APPRECIABLE
TSTM RISK TOMORROW.
