AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
639 PM CDT SAT APR 11 2015

.DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

&&

.AVIATION...A FEW ISOLATED SHOWERS ARE STARTING TO DEVELOP OVER THE
NORTHERN RANCHLANDS PRODUCING MODERATE RAIN. EXPECT AN INCREASE IN
COVERAGE ESPECIALLY ALONG AND WEST OF HWY 281. KEPT THE HRL/BRO TAFS
A LITTLE MORE OPTIMISTIC BUT WILL BE MONITORING CONVECTIVE TRENDS
CLOSELY. GUSTY WINDS/POOR VISBY CAN BE EXPECTED INVOF CONVECTION AND
CELLS WILL BE MOVING NORTH AT AROUND 15 KNOTS. CEILINGS WILL REMAIN
AROUND 1500 TO 2500 FEET WITH ABUNDANT DEBRI CLOUD FROM CONVECTION IN
MEXICO KEEPING A BKN TO OVC DECK CONCENTRATED TOWARDS THE WESTERN AREAS.
IFR/LOW MVFR CIGS ARE FORECAST TO REDEVELOP TONIGHT OVER HRL AND BRO.

&&

.PREV DISCUSSION... /ISSUED 304 PM CDT SAT APR 11 2015/

LONG TERM /MONDAY THROUGH SATURDAY/...CLOSED UPPER LOW WILL
ROTATE OUT OF NORTH MEXICO AND THENCE NORTHEAST OVER WEST TEXAS
MONDAY. DIFFLUENCE WITH SOUTHWEST FLOW OVER THE LOCAL AREA WILL
CONTINUE TO TRIGGER UNSETTLED WEATHER THE EARLY PART OF THE
WEEK...ESPECIALLY AS MOISTURE RICH LOW LEVEL AIR REMAINS IN PLACE.

A SECOND SHARP SHORT WAVE TROUGH WILL DROP SOUTH FROM THE PACIFIC
NORTHWEST TUESDAY AND WEDNESDAY...CUTTING OFF OVER THE FOUR
CORNERS WEDNESDAY. FROM THERE IT WILL DRIFT SOUTHEAST INTO THE
TEXAS PAN HANDLE ON THURSDAY...CLOSE ENOUGH OT KEEP UNSETTLED
WEATHER IN THE FORECAST. THIS REPRESENTS A SLIGHT CHANGE IN THE
FORECAST BY THE GFS SINCE WRAP AROUND DRIER AIR WILL BE DELAYED
ARRIVING INTO THE CWA FROM THURSDAY TO FRIDAY OR SATURDAY...WITH
THE ECMWF HAVING EVEN MORE TROUBLE MOVING THE UPPER LOW OUT OF THE
SOUTHERN PLAINS.

IN ESSENCE...THE ABOVE REASONING WOULD REPRESENT THE MAIN IMPETUS
FOR ADJUSTMENTS TO THE LONG TERM FORECAST AT THIS TIME. THAT IS
TRENDING POPS UP LATER IN THE WEEK. WILL OTHERWISE EXPECT CONTINUED
AMPLE CLOUD COVER WITH SEASONAL TO SLIGHTLY WARMER TEMPS THROUGH
MOST OF THE WEEK. HIGHS IN THE MID 80S AND LOWS IN THE UPPER 60S TO
LOWER 70S

MARINE...
NOW THROUGH SATURDAY NIGHT... MODERATE EAST WINDS ARE FORECAST
THROUGH THE DAY WITH SCATTERED SHOWERS AMID LOW TO MODERATE SEAS.
SOUTHEASTERLY WINDS ARE FORECAST TO INCREASE SLIGHTLY ON SUNDAY.
THUNDERSTORMS WILL BE POSSIBLE BOTH TONIGHT AND SUNDAY NIGHT BUT
PREVAILING CONDITIONS SHOULD BE FAVORABLE WITH MODERATE WINDS AND
SEAS.

MONDAY THROUGH WEDNESDAY...LIGHT TO MODERATE SOUTHEAST WINDS AND
MODERATE SEAS WILL CONTINUE WITH BROAD HIGH PRESSURE DOMINATING OVER
THE GULF OF MEXICO. THE WEATHER WILL REMAIN UNSETTLED AS FIRST
ONE...AND THEN ANOTHER UPPER DISTURBANCE ROTATES ACROSS NORTH TEXAS.
THE DISTURBANCES WILL BE CLOSE ENOUGH TO DESTABILIZE CONDITIONS OVER
THE NORTHWEST GULF...WITH SHOWERS AND THUNDERSTORMS POSSIBLE MUCH OF
THE WEEK.
