Severe Thunderstorm Warning 75, NWS Brownsville, TX

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
133 PM CDT TUE JUN 20 2006

.SHORT TERM... MIDLEVEL LOW CONTINUES TO SLOWLY CHURN TO THE
WEST...WITH THE CENTER JUST NORTH OF CRP. MODELS CONTINUE TO BE
VERY CONSISTENT WITH BRINGING THE LOW ACROSS SOUTH TEXAS THROUGH
THE NEXT 48 HOURS...WITH THE ONLY DIFFERENCES BEING AREAL COVERAGE
AND PLACEMENT OF PRECIPITATION. BOTH MODELS HAVE BEEN DECREASING
THE EXPECTED AMOUNTS OF PRECIP DURING THE LAST 24 HOURS. MOST OF
THE RAINFALL SHOULD REMAIN ON THE NORTHERN FRINGES OF OUR CWA AND
ALONG THE SEABREEZE. THE BEST FOCUS STILL LOOKS TO BE TOMORROW
WHEN THE LOW IS AT ITS CLOSEST PROXIMITY. TEMPERATURES WILL BE A
COUPLE DEGREES LOWER TOMORROW WITH INCREASED CLOUD COVER.

&&
.LONG TERM (THURSDAY THROUGH TUESDAY)...UPPER LEVEL CIRCULATION AND
ASSOCIATED THUNDERSTORM COMPLEX ALONG THE COASTAL BEND OF TEXAS IS
FORECAST TO WEAKEN WITH TIME AS IT DRIFTS WEST AND SOUTHWEST. MODEL
GUIDANCE SUITE IS BECOMING MORE CONSISTENT WITH THIS SOLUTION AND IS
TRENDING TOWARD PRECIPITATION OVER DEEP SOUTH TEXAS IN THE COASTAL
AREAS NEAR THE LAGUNA MADRE WEDNESDAY THROUGH FRIDAY.

THIS SOLUTION LOOKS SIMILAR TO PRECIPITATION THAT WOULD BE CONNECTED
TO SEA BREEZE BOUNDARIES AS THEY FORM IN THE EARLY AFTERNOON HOURS.
ALTHOUGH GFS GRID SCALE RESOLUTION IS UNLIKELY TO RESOLVE A SEA
BREEZE THE 20/12Z GFS SOLUTION IS SUGGESTING BEST CHANCE FOR
RAINFALL ALONG THE COAST EACH AFTERNOON. THE NAM12 IS ALSO TRENDING
TO A COASTAL RAINFALL SOLUTION...AND THIS SEEMS TO BE THE MORE
LIKELY SCENARIO AS THE UPPER LOW/INVERTED TROUGH MOVES INTO NORTHERN
MEXICO. TEMPERATURES ARE EXPECTED TO REMAIN IN THE 90S FOR DAYTIME
HIGHS AS WINDS HAVE A MORE EASTERLY COMPONENT...AND THEN RETURN TO
THE UPPER 90S WITH SOME 100 DEGREE READINGS BY FRIDAY.

UPPER LEVEL RIDGE RETURNS TO THE SOUTHWESTERN UNITED STATES BY
SUNDAY KEEPING THE MID/UPPER LEVELS OF THE ATMOSPHERE IN DEEP SOUTH
TEXAS IN ANOTHER DRYING TREND.
