AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
638 AM CDT SUN MAY 1 2011
.DISCUSSION...SEE AVIATION SECTION FOR 12Z TAFS.
&&
.AVIATION...12Z CRP SOUNDING SHOWS A STRONG 55 KNOTS SOUTHERLY LOW
LEVEL JET OVER THE REGION. ONLY SPORADIC MVFR CIGS OCCURRING NORTH
OF I-37 AS DRIER BOUNDARY LAYER AIR MOVING INT FROM THE SOUTH. THESE
CIGS SHOULD LIFT OR DIMINISH BY 15Z. MAIN EMPHASIS WILL BE ON THE
WIND TODAY AND THE FRONT LATE TONIGHT. LOW LEVEL WIND SHEAR WILL BE
IN THE ALI/CRP/VCT TAFS UNTIL 15Z. VERY STRONG SOUTH-SOUTHEAST WINDS
WILL OCCUR AT ALI/CRP/VCT WITH GUSTS NEAR 40 KNOTS POSSIBLE AT CRP.
THE COLD FRONT WILL APPROACH THE REGION TONIGHT WITH THE WINDS
QUICKLY TAPERING OFF THIS EVENING. THE FRONT WILL MOVE INTO THE
COT AREA AROUND 07Z MONDAY...LRD AND VCT AROUND 09Z...ALI AT 11Z
AND CRP AROUND 13Z MONDAY. CIGS WILL LOWER TO LOW MVFR/IFR FOR
THE COASTAL PLAINS OVERNIGHT WITH THE APPROACH AND PASSAGE OF THE
FRONT. ISOLATED SHOWERS WILL BE POSSIBLE WITH THE FRONT BUT FOR
NOW RAIN CHANCE NOT HIGH ENOUGH TO PUT IN THE TAFS.
&&
.PREV DISCUSSION... /ISSUED 444 AM CDT SUN MAY 1 2011/
SHORT TERM (TODAY THROUGH MONDAY)...THERE WILL BE BIG CHANGES FROM
TODAY AND MONDAY. ONE MORE DAY OF VERY WARM AND WINDY CONDITIONS FOR
SOUTH TEXAS. THE GRADIENT BETWEEN A LOW PRESSURE AREA NEAR THE
HILL COUNTRY AND HIGH PRESSURE OVER THE GULF HAS PRODUCED A VERY
STRONG LOW LEVEL JET ALONG THE COAST THIS MORNING. KCRP VAD WIND
PROFILE SEEMS TO BE OVERESTIMATING THE JET...AROUND 70 KNOTS AT 2
KFT...WHILE GUIDANCE SHOWS THE JET AROUND 55 KNOTS AT 925H. THIS
JET AXIS WILL BE SLOW TO MOVE EAST TODAY. ISSUED A WIND ADVISORY
FOR THE COASTAL BEND AND VICTORIA CROSSROADS WITH THE EXCEPT OF
ARANSAS WHERE MARINE AFFECTS MAY KEEP WIND SPEEDS JUST BELOW
ADVISORY LEVEL.
STILL HAVE CONCERNS THAT MID LEVEL TEMPS WILL KEEP ADEQUATE
CONVECTIVE INHIBITION OVER THE REGION THIS AFTERNOON. BUT MOISTURE
HOLDS OVER THE EASTERN PORTIONS OF THE BRUSH COUNTRY THROUGH THIS
AFTERNOON. THERE WILL BE MODEST LOW LEVEL CONVERGENCE FORMING WEST
OF BEEVILLE ALONG WITH THE POSSIBILITY OF A WEAK SHORT WAVE TROUGH
MOVING NORTHEAST OUT OF MEXICO AHEAD OF THE MAIN UPPER TROUGH OVER
THE SOUTHERN ROCKIES. WILL SHOW A SLIGHT CHANCE OF THUNDERSTORMS
THIS AFTERNOON BETWEEN COTULLA AND BEEVILLE BUT MORE CONDITIONAL.
WILL KEEP LOW CHANCE POPS ACROSS THE NORTHERN COUNTIES TONIGHT
NEAR REGION OF STRONG LOW LEVEL WARM AIR ADVECTION AND PROXIMITY
TO WEAKER CAP.
BIG CHANCE FOR BUST ON TEMPERATURES WITH RESPECT ON TIMING OF THE
FRONT LATE TONIGHT INTO MONDAY. DISREGARDED THE NAM AS TOO STRONG
WITH THE COOLING BEHIND THE FRONT AND TOO FAST. A COMPROMISE BETWEEN
THE 00Z GFS AND SREF WAS USED FOR TIMING WITH THE FRONT. THE UPPER
TROUGH OVER THE SOUTHERN ROCKIES WILL BE MOVING INTO THE SOUTHERN
PLAINS MONDAY. THE FRONT IS EXPECTED TO ENTER THE FORECAST AREA
OVERNIGHT AND PUSH INTO THE GULF WATERS BEFORE 18Z MONDAY. WILL
ONLY SHOW A LOW END CHANCE POP FOR ELEVATED CONVECTION BEHIND THE
FRONT AS THE STRONGER ENERGY IS STILL TO THE NORTH ON MONDAY. BUT
WITH CLOUD COVER...EXPECT TEMPERATURES WILL BE MUCH COOLER.
MARINE (TODAY THROUGH MONDAY)...STRONG ONSHORE FLOW WILL CONTINUE
OVER THE WATERS WITH THE VERY STRONG LOW LEVEL JET REMAINING OVER
THE COASTAL WATERS. EXPECT THE WINDS TO DIMINISH OVER THE BAYS BY
EARLY THIS EVENING AS THE GRADIENT FINALLY WEAKENS WITH THE APPROACH
OF THE COLD FRONT. THE FRONT WILL MOVE INTO THE WATERS ON MONDAY
WITH A STRONG OFFSHORE FLOW EXPECTED BY LATE MONDAY AFTERNOON INTO
THE EVENING.
FIRE WEATHER (TODAY THROUGH MONDAY)...STRONG AND GUSTY SOUTH TO
SOUTHEAST WINDS WILL OCCUR OVER THE EASTERN PORTIONS OF THE BRUSH
COUNTRY. THIS WILL KEEP HUMIDITY A LITTLE HIGHER. EXPECT SOUTH TO
SOUTHEAST WINDS WILL BE GUSTY ALONG WITH MARGINAL RH VALUES WILL
LEAD TO AN ELEVATED FIRE DANGER THREAT FOR THE BRUSH COUNTRY LATE
THIS MORNING INTO THE AFTERNOON. THE COLD FRONT WILL MOVE THROUGH
THE REGION LATE TONIGHT AND MONDAY MORNING BUT WITH CLOUD COVER
RH VALUES WILL NOT FALL INTO RED FLAG CRITERIA FOR WESTERN AREAS.
LONG TERM (MONDAY NIGHT THROUGH SATURDAY)...A STRONG COLD FRONT IS
EXPECTED TO BE SOUTH OF THE CWA BY MONDAY NIGHT. STRONG OFFSHORE
FLOW WILL DEVELOP IN ITS WAKE ACROSS THE MARINE ZONES...ALONG WITH
BREEZY TO WINDY CONDITIONS ACROSS THE COASTAL COUNTIES. MAIN ISSUE
WILL BE POST FRONTAL PRECIP MON NITE. MODELS ARE IN PRETTY GOOD
AGREEMENT WITH THE 850MB FRONT MOVG S OF THE AREA BY TUE MORNING.
AHD OF THE 850MB FRONT...DECENT MID LEVEL CAPE...OMEGA AND LAPSE
RATES WILL BE IN PLACE WITH THE MAIN UPPER TROF AXIS SWINGING ACROSS
THE AREA. A PIECE OF THE UPPER JET WILL ALSO MOVE ACROSS OR JUST TO
THE N OF THE CWA LEADING TO DIFFLUENCE ALOFT. THEREFORE AM EXPECTING
SCT SHRA'S AND TSRA'S LATE MONDAY NIGHT THEN EXITING OFFSHORE BY TUE
MORNING. AM NOT EXPECTING SVR WX AT THIS TIME...HOWEVER A FEW STORMS
COULD BE STRONG WITH SMALL HAIL AND WIND GUSTS RANGING FROM 40 TO 50
MPH. MUCH COOLER CONDITIONS ARE EXPECTED ON TUE. WENT WITH A BLEND
OF MOS GUIDANCE WITH MX TEMPS IN THE MID 70S. MN TEMPS BOTH TUE MORN
AND WED MORN ARE PROGD TO BE IN THE LOWER TO MID 50S. MN RH VALUES
WILL BE LOWER ON TUE AND WED...HOWEVER WINDS ARE EXPECTED TO REMAIN
BELOW RED FLAG CRITERIA BOTH DAYS. ELEVATED FIRE WX CONDITIONS ARE
POSSIBLE ESPECIALLY ON TUE WHEN WINDS WILL BE LIGHT TO MOD. WINDS
WILL BE EVEN LIGHTER ON WED AS HIGH PRESSURE SETTLES ACROSS THE
AREA. ONSHORE FLOW WILL RESUME BY LATE WED AFTERNOON AS THE SFC HIGH
DRIFTS E. ONSHORE FLOW WILL STRENGTHEN THRU THE REMAINDER OF THE
WEEK USHERING IN MOISTURE AND WARMER TEMPS. THE GFS PROGS PRECIP ON
THU/FRI WITH THE RETURN FLOW...HOWEVER WILL ONLY GO WITH SILENT 10
POPS AS UPPER LEVEL ENERGY WILL BE WELL TO THE N OF THE AREA.
