DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0228 AM CDT FRI MAR 27 2015

VALID 291200Z - 301200Z

...NO SVR TSTM AREAS FORECAST...

...SUMMARY...
ISOLATED TO SCATTERED THUNDERSTORMS WILL BE POSSIBLE SUNDAY
EVENING/NIGHT FROM PARTS OF THE SOUTHERN GREAT PLAINS TO THE
MID/DEEP SOUTH.

...SYNOPSIS...
A SHORTWAVE TROUGH SHOULD PROGRESS E/SE AND BECOME CENTERED FROM
ONTARIO ACROSS THE CNTRL GREAT LAKES BY EARLY MON. A SRN-STREAM
UPPER JET SHOULD DEVELOP FROM THE GULF OF CA TO THE SRN GREAT PLAINS
AHEAD OF A WEAK IMPULSE APPROACHING BAJA CA. AT THE SURFACE...A COLD
FRONT SHOULD SLOW ITS SEWD PROGRESSION IN THE MID/DEEP SOUTH AND SRN
GREAT PLAINS BY SUN NIGHT.

...SRN GREAT PLAINS TO THE MID/DEEP SOUTH...
MOISTURE RETURN WILL COMMENCE ON D2 OVER THE FAR WRN GULF AND BECOME
INCREASINGLY PERVASIVE INTO D3. WITH THIS OCCURRING BENEATH A STOUT
EML...MLCIN WILL LIKELY BE LARGE AND SHOULD PRECLUDE SURFACE-BASED
TSTM DEVELOPMENT. ONE EXCEPTION MIGHT BE ALONG THE TRIPLE-POINT NEAR
N-CNTRL TX...BUT CONFIDENCE IS TOO LOW TO WARRANT SEVERE
PROBABILITIES THIS OUTLOOK. OTHERWISE...LOWER-LEVEL WAA ALONG/N OF
THE FRONT IN A FAVORABLE LEFT-EXIT REGION OF THE SRN-STREAM UPPER
JET SHOULD FOSTER ELEVATED CONVECTION SUN EVENING/NIGHT. STRONGER
MID-LEVEL W/NWLYS SHOULD BE DISPLACED E/NE FROM WHERE WEAK BUOYANCY
IS MOST LIKELY ON THE FRINGE OF THE EML. GIVEN THIS SETUP...A RISK
FOR MARGINAL HAIL MAY EVENTUALLY BE WARRANTED.
