.PREV DISCUSSION... /ISSUED 616 PM CDT WED MAR 28 2012/

DISCUSSION...SEE AVIATION SECTION BELOW.

AVIATION...VFR CONDITIONS ARE PRESENT ACROSS MUCH OF S TX ALONG
WITH AN AREA OF THUNDERSTORMS LOCATED N OF WHITSETT TO CUERO. THIS
CONVECTION IS NOT ANTICIPATED TO MV INTO VCT AREA BUT HAVE
INCLUDED A 2 HR TEMPO DUE TO THE PROXIMITY OF THE STORMS. FARTHER S
AND W...A FEW WEAK SHRA'S PERSIST BUT ARE EXPECTED TO DIMINISH
THRU THE EVENING. CONDITIONS ARE EXPECTED TO DETERIORATE ACROSS S
TX AS ONGOING CONVECTION IN MEX MVS E AND IS EXPECTED TO MV ACROSS
S TX LATE TONIGHT THRU THU. BEST CHC OF TSRA'S LATE TONIGHT INTO
EARLY THU MORNING WILL BE LRD AND ALI...WITH VCT BEING LATER IN
THE MORNING. CRP IS THE LEAST LIKELY TO SEE CONVECTION. HAVE
INCLUDED A VCTS FOR THU MORNING FOR VCT AND CRP GIVEN THAT IT'S
LATER IN THE PERIOD AND LESS CERTAINTY. AS FOR CIGS AND/OR
VSBYS...AM EXPECTING MVFR CONDITIONS TO DVLP BY LATE EVENING FOR
VCT AND THEN THE REST OF THE AREA WILL BE GENERALLY VFR EXCEPT IN
AND AROUND CONVECTION WHERE CONDITIONS COULD DROP AS LOW AS LIFR
BRIEFLY.

PREV DISCUSSION... /ISSUED 314 PM CDT WED MAR 28 2012/

SHORT TERM...RAIN CHANCES WILL BE IMPROVING THE NEXT COUPLE DAYS
AS A WEAKNESS PERSISTS IN THE FLOW ALOFT AND MOISTURE VALUES
REMAIN HIGH. PWATS HAVE INCREASED TO 1.60 INCHES OVER MOST OF
SOUTH TEXAS WITH A LARGE VORT MAX PIVOTING FROM THE WESTERN HILL
COUNTRY INTO THE NORTHERN COASTAL BEND. THE EASTERN MOST SPOKE OF
THIS VORT MAX WAS ENHANCING CONVECTION OVER THE NORTHEAST COASTAL
BEND ATTM WHERE THE ATMOSPHERE HAS RECOVERED FROM THE MORNING MCS.
EXPECT THIS ACTIVITY TO PERSIST THROUGH EARLY EVENING WITH ANOTHER
ROUND DEVELOPING OVER THE BRUSH COUNTRY LATE TONIGHT AS THE NEXT
S/W APPROACHES FROM CENTRAL MEXICO. INCREASED POPS TO GOOD CHANCE
THURSDAY AND THURSDAY NIGHT AS A STEADY STREAM OF S/W'S ARE
PROGGED TO MOVE THROUGH THE AREA EMBEDDED WITHIN THE SUBTROPICAL
JET. SEVERAL ROUNDS OF CONVECTION ARE ANTICIPATED DURING THIS
TIME...HOWEVER TIMING AND LOCATION OF CONVECTION IS DIFFICULT TO
FCST. NOT EXECTING SEVERE WEATHER DUE TO WEAK SHEAR...ALTHOUGH A
FEW PULSE STORMS ARE NOT OUT OF THE QUESTION GIVEN DECENT
INSTABILITY. TRENDED OVERNIGHT LOWS SLIGHTLY COOLER DUE TO
POTENTIAL FOR RAIN COOLED AIR.

LONG TERM (THURSDAY NIGHT THROUGH WEDNESDAY)... MODELS...ESPECIALLY
GFS ARE STILL INDICATING LINGERING PRECIP THROUGH FRIDAY AFTER THE
PASSAGE OF A SHORTWAVE ON THURSDAY. HAVE KEPT 20 TO 40 POPS IN FOR
FRIDAY AND LOWER POPS FRIDAY NIGHT. GFS IS INDICATING ANOTHER MCS
POTENTIALLY COMING OUT OF MEXICO OVERNIGHT THURSDAY NIGHT WITH A
FAVORABLE THETA E RIDGE FOR SUPPORT...HOWEVER MOISTURE FLUX
CONVERGENCE AND TEMPERATURE ADVECTION AT 850 SEEM SOMEWHAT LOW. NAM
NOT REALLY INDICATING THIS POTENTIAL MCS AT ALL. MAY END UP LOWERING
THESE POPS IN TIME IF OTHER MODELS DON/T START INDICATING BETTER
PRECIP CHANCES. WEEKEND LOOKS TO WARM UP A BIT ACROSS THE AREA WITH
HIGH TEMPS INTO THE MID 90S WEST BY SUNDAY AND MONDAY. MEX GUIDANCE
HAS BEEN A BIT WARMER FOR LAREDO...BUT SEEMS LIKE MOS GUIDANCE HAS
FREQUENTLY BEEN TOO HIGH FOR THIS AREA THROUGH THE WINTER AND
SPRING. A COLD FRONT IS SHOWING UP IN MODELS FOR EARLY NEXT WEEK.
GFS MUCH MORE PROGRESSIVE WITH THE FRONT THAN EARLIER MODELS HAD
INDICATED...PAST RUNS WERE STALLING THE FRONT OVER THE AREA WHILE
ECMWF BRINGS IT THROUGH. 12Z RUNS NOW THE GFS PUSHES IT THROUGH MUCH
MORE QUICKLY THAN PREVIOUSLY. WITH THE ECMWF BEING MUCH MORE
CONSISTENT WITH THE FRONT THAN THE GFS HAVE CHOSEN TO FOLLOW PRETTY
CLOSELY TO THAT FOR NOW. WILL CERTAINLY MAKE ADJUSTMENTS AS WE GET
CLOSER WITH THE TIMING. AT THIS TIME IT DOESN/T LOOK LIKE A
SIGNIFICANTLY STRONG FRONT AND HAVE NOT INDICATED A STRONG CHANGE IN
TEMPERATURES BEHIND THE FRONT...AND ONLY MODERATE WINDS.
