Area forecast discussion, Mar 31, 3:41 AM CDT, 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
341 AM CDT SAT MAR 31 2007

.AVIATION...
MVFR CIGS REMAIN IN DALLAS...BUT WEST WIND SHOULD PUSH LOW CLOUDS
ON EAST VERY SOON. VFR CONDITIONS EXPECTED FOR REMAINDER OF DAY AND
EVENING.    84

&&

.DISCUSSION...
341 AM
TODAY WILL BE A DAY OF DRYING OUT ACROSS NORTH TEXAS AFTER AN
EXTENDED PERIOD OF HEAVY RAIN...FLOODING...AND SEVERE WEATHER.
WILL KEEP THE FLASH FLOOD WATCH IN EFFECT THROUGH 6 AM DUE TO
THE FINAL LINE OF STORMS CURRENTLY MOVING THROUGH ABOUT THE
SOUTHEASTERN HALF OF THE AREA. WILL ALSO KEEP SHORT FUSED FLOOD
WARNINGS GOING THROUGH SUNRISE ACROSS MANY NORTH TEXAS COUNTIES AS
HIGH WATER IS SURE TO LINGER FOR SEVERAL HOURS BEHIND EXITING
STORMS. THE CLEARING LINE IS PROGRESSING EAST ABOUT 25 MPH AND
SHOULD CLEAR THE CWA BY MID MORNING. DRIER AIR BEHIND THE COLD
FRONT WILL DROP DEW POINTS INTO THE 40S AND 50S TODAY UNDER A
MOSTLY SUNNY SKY.

TONIGHT WILL BE MUCH COOLER THAN WE HAVE SEEN IN THE PAST COUPLE
OF WEEKS WITH LOWS IN THE UPPER 40S TO MID 50S. HOWEVER...TEMPS
WILL REBOUND QUICKLY SUNDAY AS SURFACE WINDS TURN TO THE SOUTHWEST.
WILL UNDERCUT GUIDANCE A BIT SUNDAY DUE TO SLOWER WARMING OF
SATURATED SOILS.

THE UPPER PATTERN WILL BECOME MORE PROGRESSIVE THROUGH THE WEEK
WITH A FEW WEAK WAVES ROTATING THROUGH WEST/NORTHWEST FLOW. THE
FIRST SHORT WAVE WILL MOVE ACROSS THE REGION MONDAY AFTERNOON
THROUGH TUESDAY MORNING AND BRING A CHANCE OF SHOWERS AND
THUNDERSTORMS TO MAINLY THE SOUTHERN ZONES. THE SECOND WAVE WILL
QUICKLY MOVE ACROSS THE REGION TUESDAY EVENING THROUGH EARLY
WEDNESDAY. ALTHOUGH THE WAVE WILL BE WEAK...LIFT WILL BE ENHANCED
BY THE PASSAGE OF A COLD FRONT SO WILL INCLUDE SCATTERED SHOWERS
AND THUNDERSTORMS IN THE FORECAST.

GFS CONTINUES TO BRING IN SOME LOW POPS/QPFS TO NORTH TEXAS THURSDAY
NIGHT/FRIDAY WITH A SECONDARY COLD FRONT...BUT WILL WAIT FOR SOME
MODEL CONTINUITY BEFORE ADDING POPS TO THE FORECAST.
