WATERS WILL CONTINUE TO STRENGTHEN ACROSS THE RIO GRANDE VALLEY
THROUGH THE DAY KEEPING SOUTHEAST WINDS BETWEEN 20 TO 25 KNOTS
AND GUSTS UP TO 30 KNOTS. BKN CLOUD DECK WILL QUICKLY BREAK EARLIER
THAN ANTICIPATED BECOMING SCATTERED BY MID DAY. AS THE LOW PRESSURE

&&

.PREV DISCUSSION... /ISSUED 430 AM CDT TUE MAY 28 2013/

SHORT TERM /NOW THROUGH WEDNESDAY/...UPPER LEVEL LOW ENTERING THE
NORTHWEST PACIFIC COAST WITH ITS AXIS ALONG THE PACIFIC COAST WILL
BEGIN TO DEEPEN TODAY INTO TOMORROW BECOMING MORE NEGATIVELY TILTED
AS THE UPPER LEVEL JET TAKES A DIG SOUTHWARD. AS THIS UPPER LEVEL
TROUGH DIGS SOUTHEAST THE PRESSURE GRADIENT WILL CONTINUE TO TIGHTEN
ALONG THE CENTRAL AND SOUTHERN TEXAS REGION. AS A RESULT...THE
SURFACE LEE SIDE TROUGH WILL CONTINUE TO DEEPEN THROUGH THE DAY
INCREASING THE SE INFLOW ACROSS THE CWA TODAY. SE WINDS WILL RANGE
FROM 20 TO 25 MPH WITH GUSTS UP TO 30 MPH ESPECIALLY DURING PEAK
HEATING THROUGH THE AFTERNOON. PWATS VALUES WILL BE AROUND 1.50
INCHES ACROSS THE CWA WITH SOME DRY AIR INTRUSION FROM THE WEST AT
THE UPPER LEVELS AND A WESTERLY FLOW ALOFT. THE LACK OF DEEPER
MOISTURE IN THE AREA AND THE INCREASE IN SE WINDS WILL LIMIT THE
DEVELOPMENT OF CONVECTION TODAY. ABUNDANT SUNSHINE EARLIER TODAY
WILL ALLOW FOR HIGH TEMPERATURES TO REACH THE MID 90S ACROSS MUCH OF
THE CWA WITH THE FAR WEST TRENDING A FEW DEGREES HIGHER COMPARED TO
YESTERDAY. TONIGHT...THE SE WINDS WILL REMAIN BREEZE THROUGH THE
NIGHT AS THE PRESSURE GRADIENT REMAINS STRONG  ALONG THE COAST.

THE UPPER LEVEL TROUGH WILL KEEP SOUTH TEXAS REGION UNDER DIFFLUENT
FLOW ALOFT WHICH WILL ALLOW A MORE FAVORABLE INITIATION OF CONVECTION
ALONG THE EASTERN SIDE OF THE SIERRA MADRE. THE LOW TEMPERATURES
WILL BE IN THE MID 70S ACROSS THE CWA. PWATS VALUES WILL INCREASE TO
1.70 INCHES OR MORE ALONG THE WEST. EXPECT THE SHOWER ACTIVITY TO
INITIATE ALONG EAST OF THE MOUNTAINS EARLY IN THE NIGHT AND
PROPAGATE EASTWARD THROUGH THE EARLY MORNING HOURS. THERE IS A
POSSIBILITY THAT THIS ACTIVITY CAN HOLD TOGETHER AS THE ENVIRONMENT
WILL BECOME UNSTABLE AND ENHANCE A THE SHOWER ACTIVITY ALONG THE
WESTERN PORTION OF THE CWA. INCREASED POPS TO 20 PERCENT ALONG THE
WEST. HIGH TEMPERATURES WILL REMAIN IN THE MID 90S WEDNESDAY. MOST
OF THE ACTIVITY WILL DIMINISH AS THE SE WINDS INCREASE IN THE
AFTERNOON HOURS ONCE AGAIN.

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...700MB RIDGE IS
EXPECTED TO PREVAIL ACROSS THE SOUTHEAST UNITED STATES THURSDAY
INTO FRIDAY AS AN INVERTED TROUGH DEVELOPS ACROSS THE WESTERN GULF
OF MEXICO THROUGH THE REST OF THE WEEK. TROPICAL MOISTURE ACROSS
THE BAY OF CAMPECHE IS PROGGED TO MAKE ITS WAY TOWARDS NORTHEAST
MEXICO THROUGH THE WEEKEND AS A 700MB LOW/TROUGH ACROSS THE
NORTHERN PLAINS BRINGS A SURFACE TROUGH/FRONT TOWARDS THE CENTRAL
AND SOUTHERN PLAINS SATURDAY. WITH THE WEAK COLD FRONT MOVING INTO
NORTH TEXAS SUNDAY AND THE GFS PROGGING A WEAK AREA OF LOW
PRESSURE DEVELOPING ACROSS THE BAY OF CAMPECHE THROUGH THE
WEEKEND...WILL GO AHEAD AND MENTION A SLIGHT CHANCE OF SHOWERS AND
THUNDERSTORMS FOR SUNDAY AND MONDAY AS INSTABILITY AND MOISTURE
INCREASES ACROSS SOUTH TX THROUGH THE REST OF THE FORECAST PERIOD.
