DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0118 AM CST THU NOV 26 2009
VALID 281200Z - 291200Z
...SYNOPSIS/FCST...
POSITIVE-TILT LARGE SCALE TROUGH WILL CONTINUE TO EVOLVE OVER THE
WRN TWO-THIRDS OF THE COUNTRY EARLY THIS WEEKEND. THE TROUGH WILL
MAINTAIN A SPLIT CHARACTERISTIC WITH THE NRN WAVE CONTINUING EWD
ACROSS THE NRN PLAINS/UPR GRTLKS. STRONGER SRN BRANCH WILL CONTINUE
DIGGING INTO NRN BAJA/NWRN SONORA ON SATURDAY WITH A MUCH WEAKER
IMPULSE MIGRATING EWD THROUGH THE TN VLY/GULF CST REGION.
TSTM PROBABILITIES WILL BE CONFINED TO PARTS OF THE INTERMOUNTAIN
WEST...GRT BASIN AND DESERT SW ON SATURDAY. HIGHEST CHANCES WILL
EXIST WITHIN LEFT-EXIT REGION OF A 130 KT H25 JET FROM PARTS OF SRN
CA ENE INTO AZ FROM SATURDAY MORNING INTO THE EARLY EVENING.
ALTHOUGH LLVL MOISTURE WILL LIKELY BE LIMITED...SUFFICIENT FORCING
AND SUBSEQUENT MOISTENING OF THE H7-H5 LAYER WILL CONTRIBUTE TO A
COUPLE HUNDRED J PER KG OF MUCAPE AND THE POTENTIAL RISK FOR WDLY
SCTD TSTMS. SOME THREAT MAY CONTINUE INTO SATURDAY NIGHT ACROSS
SRN/ERN AZ. DESPITE INCREASING WIND FIELDS AND SHEAR...LACK OF
SUFFICIENT MOISTURE SHOULD KEEP SVR TSTM PROBABILITIES LOW.
