DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0748 PM CDT FRI APR 01 2011
VALID 020100Z - 021200Z
...NO SVR TSTM AREAS FORECAST...
...E TX AND NW LA...
HIGH-BASED CONVECTION HAS BEEN TRYING TO DEEPEN ACROSS NE TX
ALONG/AHEAD OF A TRIPLE POINT/DRYLINE AS A MINOR IMPULSE EMBEDDED IN
FAST WNW FLOW ARRIVES. 00Z FWD SOUNDING SUGGESTED THAT WHILE THE
BOUNDARY LAYER MIXED/DRIED CONSIDERABLY DURING THE HEATING CYCLE...A
THIN LAYER OF MOISTURE WAS SAMPLED AROUND 730 MB. ASCENT AND THE
MEAGER MOISTURE MAY YET BE SUFFICIENT FOR A COUPLE OF TSTMS E AND SE
OF THE DFW METROPLEX THIS EVENING. BEFORE THE BOUNDARY LAYER COOLS
SIGNIFICANTLY...SUB-CLOUD LAYERS WILL BE RELATIVELY DRY AND GUSTY
WINDS /ISOLD SVR/ MAY ACCOMPANY ANY SUSTAINED STORM. OTHERWISE...
ACTIVITY WILL WEAKEN AND STREAM EWD INTO PARTS OF LA OVERNIGHT.
...MIDWEST/MID-OH VALLEY...
COMBINATION OF VERY STEEP LAPSE RATES /MINUS 30 DEG C AT H5/ AND
PWATS JUST BELOW ONE-HALF OF AN INCH HAVE CONTRIBUTED TO
DIURNALLY-ENHANCED CONVECTION/TSTMS ACROSS THE REGION. ACTIVITY
SHOULD DIMINISH THROUGH THE EVENING WITH LOSS OF INSOLATION. UNTIL
THEN...SMALL HAIL AND GUSTY WINDS MAY ACCOMPANY A COUPLE OF STORMS.
