AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE FORT WORTH TX
1008 AM CDT TUE MAR 20 2012

.AVIATION...
THE MAIN AREA OF RAIN HAS ENDED AT THE METROPLEX AIRPORTS...AND
WILL BE ENDING AT WACO IN THE NEXT HOUR. VFR CONDITIONS HAVE ALREADY
RETURNED TO MOST OF THE METROPLEX SITES...AND CONTINUED IMPROVEMENTS
ARE EXPECTED AT THE REMAINING SITES AND WACO IN THE NEXT HOUR OR TWO.
ISOLATED THUNDERSTORMS MAY REDEVELOP MID TO LATE AFTERNOON AS THE
UPPER LEVEL LOW APPROACHES...BUT THE CHANCES AT THE AIRPORTS IS
TOO LOW TO MENTION AT THIS TIME. NORTHEAST WINDS IN THE METROPLEX
AND NORTHWEST WINDS AT WACO SHOULD BECOME SOUTHWEST AROUND MIDDAY.

58

.../PREVIOUS AVIATION DISCUSSION/...
/12Z TAFS/

CONCERNS...LIGHTNING AND MVFR CIGS EARLY IN TAF PERIOD.

PERSISTENT (BUT ONLY OCCASIONAL) LIGHTNING NECESSITATED ANOTHER
AIRPORT WEATHER WARNING (NOW THROUGH 10 AM). BACK EDGE OF THE
PRECIP HAS ENTERED FWD CWA...AND EXPECT LIGHT RAIN TO TAPER OFF BY
MIDDAY.

WINDS...
COMMERCIAL AIRPORTS MAY BE ABLE TO RETURN TO SOUTH FLOW AROUND
MIDDAY.

CLOUDS...
LOW DECKS WILL EVACUATE WHEN RAIN ENDS. SOME POTENTIAL FOR MVFR
CIGS WEDNESDAY MORNING...BUT MOISTURE WILL BE QUITE THIN WITH
SOUTHWESTERLY FLOW ABOVE IT WITHIN A MILE OF THE SURFACE.

.UPDATE...
BACK EDGE OF PRECIPITATION HAS ACCELERATED OVER THE LAST COUPLE OF
HOURS AND SHOULD CONTINUE TO MOVE EAST INTO EARLY AFTERNOON. HAVE
ADJUSTED POPS ACCORDINGLY AND WILL CANCEL THE FLASH FLOOD WATCH
OVER THE WESTERN COUNTIES WHERE RAIN HAS ENDED. UPPER LEVEL LOW
CONTINUES TO SPIN ACROSS WEST TEXAS AND FORECAST SOUNDINGS FOR
LATER THIS AFTERNOON DO INDICATE SOME AVAILABLE ELEVATED
INSTABILITY. HIGH RESOLUTION GUIDANCE SUGGESTS THAT SOME ISOLATED
THUNDERSTORMS MAY DEVELOP LATER THIS AFTERNOON CLOSER TO THE CORE
OF THE UPPER LOW. WILL MAINTAIN SOME 20 POPS ACROSS MUCH OF THE
AREA FOR ISOLATED THUNDERSTORMS. GIVEN THE STEEP LAPSE
RATES...MARGINALLY SEVERE HAIL WILL BE POSSIBLE WITH ANY STORMS
THAT DO DEVELOP THIS AFTERNOON.

DUNN

&&

.PREV DISCUSSION... /ISSUED 404 AM CDT TUE MAR 20 2012/
RAIN AND THUNDERSTORMS WILL CONTINUE ACROSS NORTH TEXAS THIS
MORNING AS LARGE SCALE LIFT REMAINS OVER THE REGION. PRECIPITATION
WILL END FROM WEST TO EAST THIS AFTERNOON AS DRIER AIR MOVES IN
FROM THE WEST. WE HAVE DECIDED TO LEAVE THE FLASH FLOOD WATCH IN
EFFECT THROUGH 700 PM THIS EVENING SINCE ALL AREAS ARE SATURATED AND
ANY ADDITIONAL PRECIPITATION COULD RESULT IN FLOODING PROBLEMS.
THE UPPER LOW WILL MOVE INTO WEST TEXAS TODAY...LIFT NORTHWARD
INTO OKLAHOMA TONIGHT...AND THEN BECOME NEARLY STATIONARY
WEDNESDAY THROUGH THURSDAY. SOME ELEVATED SHOWERS AND ISOLATED
THUNDERSTORMS WILL BE POSSIBLE WEDNESDAY...ESPECIALLY ACROSS THE
NORTHERN AND EASTERN COUNTIES. THE UPPER LOW WILL FINALLY BEGIN TO
PULL OUT OF THE REGION THURSDAY NIGHT AND UPPER LEVEL HIGH
PRESSURE WILL BUILD IN FROM THE WEST. THEREFORE...EXPECT
DECREASING CLOUDS AND WARMER TEMPERATURES ON THE WEEKEND. THE
UPPER RIDGE AXIS SHOULD SHIFT EAST OF NORTH TEXAS SUNDAY NIGHT
WHILE AN UPPER TROUGH DEEPENS ON THE WEST COAST. THIS PATTERN WILL
RESULT IN SURFACE LEE TROUGHING AND A RETURN OF LOW LEVEL MOISTURE
TO NORTH TEXAS. IT DOES NOT APPEAR THAT NORTH TEXAS WILL RECEIVE
ANY SIGNIFICANT PRECIPITATION WITH THIS NEXT LOW PRESSURE SYSTEM
EARLY NEXT WEEK.
