NWS STORM PREDICTION CENTER NORMAN OK
1020 AM CDT FRI MAY 14 2010
AREAS AFFECTED...W CNTRL THROUGH NWRN TX
CONCERNING...HEAVY RAINFALL
VALID 141520Z - 141815Z
VERY HEAVY RAIN WITH RATES LOCALLY FROM 1.5 TO 2+ INCHES PER HOUR
WILL REMAIN LIKELY FROM PARTS OF N-CNTRL THROUGH NW TX NEXT FEW
HOURS. HEAVY RAIN THREAT MAY EVENTUALLY SPREAD INTO PORTIONS OF THE
DALLAS-FORT WORTH METRO AREA BY LATE MORNING OR EARLY AFTERNOON.
A QUASI-STATIONARY FRONT EXTENDS FROM NRN AR SWWD TROUGH N-CNTRL AND
NWRN TX INTO FAR WRN TX. BROAD ZONE OF 30-35 KT SLY BOUNDARY LAYER
FLOW IS TRANSPORTING HIGHER THETA-E AIR NWD FROM THE MODERATELY
UNSTABLE WARM SECTOR THAT IS IN PLACE ACROSS CNTRL AND ERN TX. THIS
PROCESS SHOULD SUSTAIN THUNDERSTORM DEVELOPMENT OVER NRN TX AS MOIST
PARCELS ARE LIFTED TO THEIR LFCS IN VICINITY OF CONSOLIDATED
FRONT/OUTFLOW BOUNDARY. A SLOW SEWD PROPAGATION OF THE CONVECTION IS
OCCURRING OVER N-CNTRL TX WHERE THE FRONT IS BEING ENHANCED BY
CONVECTIVE OUTFLOW...AND THIS MAY RESULT IN THE ZONE OF HEAVY RAIN
REACHING THE DALLAS-FORT WORTH AREA BY MID-DAY. HIGH PRECIPITABLE
WATER OF 1.5-1.75 INCHES AND TENDENCY FOR STORMS TO TRAIN NEWD ALONG
THE SLOW MOVING BOUNDARY WILL CONTRIBUTE TO RAINFALL RATES LOCALLY
UP TO 2 INCHES PER HOUR.
