AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
458 AM CDT FRI MAY 10 2013

.DISCUSSION...
AS SUSPECTED IN THE PREVIOUS DAYS...VAST MAJORITY OF THINGS ARE
BEING DRIVEN ON THE MESOSCALE. VERY FEW IF ANY 00Z MODELS INITIALIZED
OVERNIGHT WX THAT OCCURRED. IT'S NOT UNCOMMON IN THESE SITUATIONS
& TIME OF YEAR, BUT MAKES IT HARD TO FOLLOW ANY OF THEM FOR SPECIFIC
SHORT TERM DETAILS AND/OR CONFIDENCE.

NEXT UPPER IMPULSE CAN BE SEEN TO OUR WEST ON SAT & RADAR PIX.
PRECIP IS IN THE PROCESS OF INCREASING IN AREAL COVERAGE. WOULD
EXPECT THESE STORMS TO EVENTUALLY START PUSHING SE AS HIGH PRES
AND FRONT SLIDES FURTHER SOUTH. ISSUED A FLASH FLOOD WATCH FOR
PARTS OF SE TX (SEE BELOW) WHO SAW 4-7" RAIN LATE THURS. FAIRLY
LOW CONFIDENCE AS TO THE OVERALL THREAT THERE - ESP IF THE CELLS
KEEP MOVING OR DON'T TRAIN - BUT THIS NEXT DISTURBANCE IS COMING
IN A LITTLE FASTER THAN I'D LIKE AND PATTERN STILL SUPPORTS SOME
TRAINING. WOULD'VE PREFERRED THEY HAVE A LITTLE MORE TIME TO
RECOVER BETWEEN RAIN EPISODES. MENTIONED LOCALLY HEAVY RAINFALL
ELSEWHERE ALONG WITH THE POSSIBILITY OF AN ISOLATED SEVERE CELL OR
TWO ALSO.

MODELS ALL GENERALLY AGREE WITH A STRONGER DISTURBANCE MOVING
ALONG THE FRONT WHICH **SHOULD** BE SITUATED NEAR THE COAST LATER
TONIGHT BRINGING ANOTHER ROUND OF PRECIP. THEY'VE ALL BEEN PRETTY
CONSISTENT SHOWING THIS FOR THE LAST SEVERAL DAYS. MAJORITY OF ANY
STRONGER ACTIVITY SHOULD BE ALONG/SOUTH IF I-10 AND CLOSER TO THE
COAST. HOPEFULLY THE MATAGORDA BAY AREA SEES A GOOD SOAKER THAT
HAS BEEN ADVERTISED BY THE MODELS AS THAT AREA OF SE TX REALLY
NEEDS THE RAIN. FRONT SHOULD PUSH OFF THE COAST SAT MORNING WITH
RAIN MOSTLY TAPERING OFF IN THE AFTN.

ELONGATED H5 TROF STRETCHING FROM THE GREAT LAKES TO BAJA HAS
MOSTLY BEEN THE TRIGGER FOR ALL OF THIS AS DISTURBANCES IN THE SW
FLOW ALOFT PUSH THRU. SOUTHERN PARTS OF THIS TROF AROUD BAJA SHOULD
EVENTUALLY GET CUTOFF FROM THE MAIN FLOW THIS WEEKEND. RIDGING AND
DRIER WX SHOULD BRIEFLY TAKE SHAPE HERE EARLY IN THE WEEK...BUT
THE CUTOFF LOW SHOULD EVENTUALLY OPEN UP AND KICK OUT TOWARD
MIDWEEK BRINGING SOME SLIGHT RAIN CHANCES BACK INTO THE AREA. NO
FURTHER FRONTS ON THE HORIZON AFTER SATURDAY'S THRU AT LEAST DAY
10. SUMMER IS ON THE HORIZON. 47

&&

MARINE...
NOT A LOT OF CHANGES WITH THE FCST AS LIGHT/MODERATE ONSHORE WINDS
PERSIST TODAY/TONIGHT. STILL LOOKING FOR A BRIEF SHIFT OF THE LOW-
LEVEL FLOW TO THE NE THIS WEEKEND AS A WEAK COOL FRONT NUDGES INTO
COASTAL WATERS. AS HIGH PRESSURE MOVES OFF TO THE EAST...WE SHOULD
SEE A GRADUAL RETURN OF ONSHORE WINDS FOR NEXT WEEK. NOT EXPECTING
ANY CAUTION/ADVISORY FLAGS FOR OUR MARINE AREAS THESE NEXT SEVERAL
DAYS. 41

&&

AVIATION...
MESSY MESSY FCST AS ONGOING ACTIVITY SLOWLY MOVES OUT TO THE EAST.
ATTM NOT A LOT OF CONFIDENCE WITH WHEN/WHERE (OR EVEN IF) THE PCPN
WILL REDEVELOP THIS AFTN. BUT MODELS HAVE BEEN PERSISTENT WITH THE
IDEA OF MORE STORMS LATE TODAY. WILL LIKELY OPT FOR VCTS AND TEMPO
MVFR CIGS/VIS IN THE AFTN. 41

THE NEXT UPPER LEVEL DISTURBANCE AND ASSOCIATED SHOWERS AND
THUNDERSTORMS WILL BE MOVING INTO THE REGION FROM CENTRAL TEXAS
LATER THIS MORNING AND AFTERNOON. MOST LOCATIONS WILL SEE AVERAGE
RAINFALL AMOUNTS BETWEEN 1/2 AND 1 INCH. HOWEVER...THE WEATHER
PATTERN ALSO SUPPORTS TRAINING STORMS THAT CAN PRODUCE LOCALIZED
VERY HEAVY RAINFALL. YESTERDAY AND LAST NIGHT...SWATHS OF 3 TO 7
INCH AMOUNTS WERE OBSERVED AND SIMILAR AMOUNTS ARE AGAIN POSSIBLE
TODAY. CONFIDENCE AS TO EXACTLY WHERE AND WHEN THIS WILL OCCUR IS
LOW. LOCATIONS THAT HAVE ALREADY RECEIVED HEAVY RAIN ARE AT A
GREATER RISK OF FLOODING SHOULD SIMILAR DOWNPOURS OCCUR THERE
TODAY.

ANOTHER DISTURBANCE IS FORECAST TO MOVE ACROSS SOUTHERN PARTS OF
THE REGION TONIGHT. AREAS GENERALLY SOUTH OF I-10...AND OFFSHORE...APPEAR
TO HAVE THE BETTER CHANCES OF SEEING HAZARDOUS WEATHER WITH THIS
DISTURBANCE.

THE PRIMARY WEATHER THREAT THROUGH TONIGHT WILL BE FLOODING ASSOCIATED
WITH LOCALIZED HEAVY RAINFALL. A FEW ISOLATED SEVERE STORMS ARE
ALSO POSSIBLE WITH SOME DAMAGING WINDS AND HAIL.
