AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
406 AM CDT TUE MAY 1 2012

.DISCUSSION...
ONGOING LINE OF THUNDERSTORMS CONTINUES AN OVERALL WEAKENING TREND
AS IT MOVES INTO LESS FAVORABLE ENVIRONMENT FARTHER EAST. OK
COUNTIES HAVE BEEN DROPPED FRONT SEVERE THUNDERSTORM WATCH AND AR
PORTION WILL EXPIRE AT 5 AM. STORMS SHOULD CLEAR THE FORECAST
AREA BY 12Z...WILL TAKE A FINAL LOOK AT RADAR TRENDS TO DETERMINE
EARLY FIRST PERIOD POPS. POTENTIAL FOR ADDITIONAL DEVELOPMENT NOT
CLEAR...BUT A FEW RESIDUAL BOUNDARIES LEFT OVER FROM LATEST ROUND
OF CONVECTION WILL BE POTENTIAL FOCUS. WARMING MID LEVEL TEMPS
WILL LEAD TO INCREASING CAP AND THUS...OVERALL CHANCE WILL BE LOW.

REMAINDER OF THE FORECAST PERIOD WILL BE MARKED BY A BUILDING
UPPER LEVEL RIDGE OVER THE SOUTHERN STATES. PERSISTENT DRY LINE
FEATURE WILL REMAIN OVER THE HIGH PLANS FOR THE NEXT FEW DAYS AT
LEAST AND THERE REMAINS A VERY SMALL THREAT OF ANY DRY LINE STORMS
MAKING A RUN EAST WED/THU AS STEERING FLOW REMAINS WSW...LESS THAN
20 PERCENT CHANCE. WARM AND HUMID AIRMASS WILL BECOME ENTRENCHED
OVER THE AREA AND SOME MODELS SHOW A WEAK SUBTROPICAL IMPULSE
LIFTING NE ACROSS TX BY THE WEEKEND. WILL KEEP THE FORECAST DRY
BUT THIS COULD LEAD TO AT LEAST ISOLATED STORMS. ECMWF AND GFS AT
ODDS NEXT WEEK REGARDING POTENTIAL COLD FRONT.
