.DISCUSSION...

LOOK AT THE PEAK HEAT INDICES FOR THE DAY AND DETERMINE IF ANY
COUNTIES CAN BE SHAVED OFF BEFORE ISSUING ANOTHER ADVISORY FOR

.PREV DISCUSSION... /ISSUED 314 PM CDT SAT AUG 22 2009/
FRONTAL BOUNDARY NOW STRETCHING FROM ROUGHLY MADISONVILLE TO
HUNTSVILLE TO LIVINGSTON. CU FIELD BUILDING ALONG THE BOUNDARY AND
SOME TSTMS STARTING TO GET GOING JUST NW OF THE CWA. 12Z 4KM WRF
SEEMS TO HAVE A PRETTY GOOD HANDLE ON THE SITUATION AND SHOWS THE
POTENTIAL FOR SCT LATE AFTN/EVNG ACTIVITY ACROSS SW 1/2 OF THE CWA
WITH CONTINUED HEATING. DOWNBURSTS REMAIN A POSSIBILITY IN THE
STRONGER CELLS.
DIFFUSE BOUNDARY REMAINS IN THE REGION TOMORROW PROBABLY ALONG THE
I-45 & HWY 290 CORRIDOR. PWS REMAIN AROUND 1.8 BUT H5 RIDGE
EDGES A BIT CLOSER TO THE AREA FROM THE W SO WELL HAVE TO
OVERCOME MORE SUBSIDENCE TO GET THINGS GOING. FRONTAL BOUNDARY
WASHES OUT AND/OR MOVES BACK NE EARLY NEXT WEEK AS SFC HIGH
PRESSURE MOVES TOWARD THE E COAST. WILL PROBABLY STILL SEE SOME
RECIRCULATED DRY AIR MOVING INTO THE REGION THRU MIDWEEK...AND
ALONG WITH THE MID LEVEL RIDGE...PROVIDE JUST LOW RAIN CHANCES AT
BEST.
FCST FOR THE SECOND HALF OF THE WEEK IS SOMEWHAT UNCLEAR. MODELS
INDICATING THE RIDGE RETROGRADING BACK WEST WITH A MID LEVEL
WEAKNESS TAKING ITS PLACE OVER SE TX. MODELS HAVE BEEN FLUCTUATING
ON TIMING & PLACEMENT OF THE WEAKNESS FROM RUN-TO-RUN WHICH WOULD
HAVE AN IMPACT ON POPS/TEMPS. PREVIOUS FCSTS HAVE LEANED TOWARD
ECMWF SOLN - WHICH THE 12Z RUN IS A BIT DIFFERENT THAN YDAYS 00Z.
PREFER TO SEE SOME MORE CONSISTENCY BEFORE MESSING WITH THE EXTENDED
RANGE FCST. 47
MARINE...
A WEAK FRONTAL BOUNDARY MAY WORK ITS WAY OFF THE COAST TONIGHT OVER
THE COASTAL WATERS EAST OF GALVESTON. HOWEVER...WITH A SURFACE HIGH
PRESSURE DEVELOPING OFF THE COAST SUNDAY...THE LAND BREEZE AND
SEABREEZE CIRCULATION WILL HAVE THE BIGGEST IMPACT ON THE WIND
DIRECTION AND SPEED. ONSHORE WINDS ARE EXPECTED TO DEVELOP MONDAY AS
THE CENTER OF THE HIGH MOVES EASTWARD. 40
1241 PM AVIATION... VFR EXPECTED FOR THE MOST PART. THE MAIN ITEM
OF CONCERN IS THE THUNDERSTORM CHANCE FOR THIS AFTERNOON AND
EVENING. A WEAK FRONTAL BOUNDARY WAS LOCATED FROM JUST NORTH OF
MADISONVILLE TO JUST NORTH OF KUTS. VISIBLE SATELLITE SHOWED
CUMULUS FORMING OVER THE PAST HOUR ALONG ABOUT A 30 MILE WIDE BAND
SOUTH OF THIS BOUNDARY. REALLY DO NOT EXPECT MUCH SHOWER OR
THUNDERSTORM DEVELOPMENT UNTIL THE SEABREEZE GETS GOING AFTER 21Z
AND MOVES FAR ENOUGH INLAND TO INTERACT WITH THE FRONT TO THE
NORTH. COVERAGE LOOKS TO BE ISOLATED NORTH OF INTERSTATE 10 AND
SCATTERED OVER TO THE SOUTHWEST OF THE BIG AIRPORTS. THE 12 KM NAM
INDICATED THE BEST TIME FRAME FOR STORM CHANCES WILL BE BETWEEN
21Z AND 03Z.
SUNDAY MORNING BETWEEN 10Z AND 13Z SOME MVFR CONDITIONS FOR LIGHT
FOG MAY OCCUR AT KCXO AND KLBX. 40
