AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
211 PM CDT MON APR 2 2012

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...LOW PRESSURE OVER NEW
MEXICO INTERACTING WITH HIGH PRESSURE OVER THE GULF HAS RESULTED IN
MODERATE TO STRONG WINDS OVER DEEP SOUTH TEXAS THIS AFTERNOON. THE
SOUTHEAST WINDS ARE EXPECTED TO DECREASE A LITTLE OVERNIGHT BUT NOT
FULLY DECOUPLE. LOW CLOUDS AND PATCHY FOG IS POSSIBLE LATE TONIGHT
BUT WINDS SHOULD REMAIN HIGH ENOUGH THAT ANY FOG THAT DEVELOPS
SHOULD NOT BE DENSE. LOW TEMPERATURES TONIGHT WILL REACH THE 70S
ACROSS MUCH OF THE AREA. A WEAK FRONT/BOUNDARY WILL APPROACH DEEP
SOUTH TEXAS LATE TONIGHT INTO TUESDAY. THE BOUNDARY IS EXPECTED TO
MOVE ACROSS THE AREA LATE TUESDAY MORNING THROUGH TUESDAY AFTERNOON.
HAVE MENTIONED ISOLATED THUNDERSTORMS OVER THE NORTH TONIGHT AND
AREA WIDE FOR TUESDAY. THERE IS NOT A STRONG PUSHED BEHIND THIS
FRONT AND THIS FEATURE WILL LIKELY BE WASHED OUT BY LATE TUESDAY.
ANY THUNDERSTORMS THAT DEVELOP OVER DEEP SOUTH TEXAS COULD BECOME
STRONG/SEVERE WITH THE MAIN THREATS BEING GUSTY WINDS AND SMALL
HAIL. HIGH TEMPERATURES WILL REMAIN IN THE MID 80S ACROSS THE
EASTERN COASTAL COUNTIES AND IN THE MID 90S INTO THE FAR WEST ALONG
THE RIO GRANDE. SOUTHEAST WINDS QUICKLY RETURN BY TUESDAY EVENING.

.LONG TERM /WEDNESDAY THROUGH MONDAY/...THE 500MB LOW ACROSS THE
TEXAS AND OKLAHOMA PANHANDLES WEDNESDAY IS EXPECTED TO MOVE
EASTWARD THURSDAY AS WHAT IS LEFT OF A CONVECTIVE BOUNDARY ACROSS
THE MIDDLE AND UPPER TX COAST WASHES OUT AND A SURFACE TROUGH
ACROSS EAST TX MOVES EASTWARD INTO THE LOWER MISSISSIPPI RIVER
VALLEY. A 500MB RIDGE IS STILL PROGGED TO MOVE ACROSS THE CENTRAL
UNITED STATES FRIDAY. HARD TO SAY IF THUNDERSTORMS WILL DEVELOP
ACROSS THE CWA WEDNESDAY AS MESOSCALE FEATURES WILL DETERMINE WHEN
AND IF STORMS DEVELOP ACROSS THE VALLEY. WILL CONTINUE TO MENTION
ISOLATED SHOWERS AND THUNDERSTORMS WITH THE POSSIBILITY OF STRONG
TO SEVERE THUNDERSTORMS AS SURFACE INSTABILITY WILL REMAIN HIGH
WITH WARM AND MOIST AIR ACROSS THE AREA. RAIN CHANCES APPEAR
LIMITED THROUGH THE REST OF THE WEEK UNTIL THE WEEKEND AS LOW TO
MID LEVEL MOISTURE INCREASES ACROSS NORTHERN MEXICO INTO WEST TX
AS A CONVECTIVE FRONTAL BOUNDARY MOVES INTO NORTH TX SUNDAY. THE
12Z GFS PROGS MOST OF THE RAIN CHANCES WELL TO THE NORTH OF THE
RIO GRANDE PLAINS THROUGH THE REST OF THE FORECAST PERIOD BUT THE
00Z ECMWF CONTINUES TO SHOW MOISTURE POOLING ACROSS NORTHEAST
MEXICO INTO SOUTHWEST TX SO WILL MENTION A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS FOR THE REST OF THE WEEKEND INTO EARLY
NEXT WEEK.
&&

.MARINE...
TONIGHT THROUGH TUESDAY NIGHT...WINDS OVER THE LAGUNA MADRE HAVE
INCREASE TO SMALL CRAFT ADVISORY CRITERIA THIS AFTERNOON. HAVE
ISSUED A SMALL CRAFT ADVISORY FOR THE LAGUNA MADRE UNTIL 8 PM THIS
EVENING. MODERATE TO STRONG SOUTHEAST WINDS WILL PERSIST OVER THE
LOWER TEXAS COAST TONIGHT THROUGH TUESDAY DUE TO THE TIGHT PRESSURE
GRADIENT. THE PRESSURE GRADIENT BEGINS TO RELAX BY TUESDAY AFTERNOON
AS A WEAK FRONT/BOUNDARY APPROACHES DEEP SOUTH TEXAS. SEAS WILL
SLOWLY BUILD TO 5 TO 7 FEET TONIGHT THROUGH TUESDAY AHEAD OF THE
FRONTAL PASSAGE. SEAS WILL BEGIN TO SUBSIDE TUESDAY NIGHT.

WEDNESDAY THROUGH SATURDAY...LIGHT SOUTH WINDS WILL PREVAIL ACROSS
THE COASTAL WATERS WEDNESDAY AND REMAIN LIGHT THROUGH THE REST OF
THE WEEK AS THE PRESSURE GRADIENT REMAINS WEAK ACROSS THE WESTERN
GULF OF MEXICO. WINDS ARE EXPECTED TO INCREASE SLIGHTLY SATURDAY
AS HIGH PRESSURE ACROSS THE EASTERN UNITED STATES PROVIDES A
SLIGHTLY STRONGER PRESSURE GRADIENT ACROSS THE COASTAL WATERS.
