Area forecast discussion, Mar 15, 8:38 PM CDT, 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HOUSTON/GALVESTON TX
838 PM CDT THU MAR 15 2012

.UPDATE...
SEE EVENING UPDATE.

&&

.DISCUSSION...
NOT MANY CHANGES PLANNED TO THE CURRENT FORECAST. LOW CLOUDS ARE
BEGINNING TO DEVELOP NEAR THE COAST AND FEEL CLOUD COVER WILL
EXPAND INLAND OVERNIGHT AND SCATTER OUT AGAIN ON FRIDAY. THE
GRADIENT LOOKS A BIT WEAKER TONIGHT COMPARED TO LAST NIGHT BUT
CURRENT WIND FORECAST LOOKS OK. WILL BUMP MIN TEMPS UP A BIT DUE
TO INCREASED CLOUD COVER OTHERWISE NO CHANGES. 43

&&

.CLIMATE...WILL UPDATE/ISSUE A NEW DROUGHT STATEMENT LATER
TONIGHT. CONDITIONS HAVE IMPROVED SIGNIFICANTLY DESPITE SOME D-3
CLASSIFICATIONS OVER THE SW ZONES. LAKE SOMERVILLE HAS ONCE AGAIN
REACHED 100 PERCENT CAPACITY. 43

.PREV DISCUSSION... /ISSUED 631 PM CDT THU MAR 15 2012/

AVIATION...
THE SURFACE HIGH PRESSURE CENTERED NEAR THE MOUTH OF THE
MISSISSIPPI RIVER EXTENDED ACROSS THE UPPER TEXAS COASTAL AREAS
EARLY THIS EVENING. THE RESULTING ONSHORE FLOW WILL CONTINUE TO
ADVECT GULF MOISTURE ACROSS SE TX OVER THE NEXT 24 TO 30 HOURS OF
THE FORECAST PERIOD. THE SURFACE OBSERVATIONS AT 23Z ALREADY
SHOWED MVFR TO IFR CONDITIONS PUSHING INLAND FROM THE GULF. KGLS
WILL HAVE THE BEST CHANCES FOR IFR TO LIFR CONDITIONS TONIGHT
WHILE MVFR IS MOST LIKELY OVER THE INLAND SITES. PERSISTENCE IS
THE BEST FORECAST AS THE GUIDANCE IS AGAIN TOO LOW AND THE MODEL
RAW OUTPUT IS SHOWING THE SAME FORECAST AS 24 HOURS AGO. THERE
WILL BE A CHANCE FOR IFR CEILINGS AT A FEW SITES...OTHERWISE WILL
LIFT THE MVFR CEILINGS DURING THE MID AND LATE MORNING ON FRIDAY.
MVFR CONDITIONS WILL LIKELY LINGER AT KGLS THROUGHOUT THE
AFTERNOON.

40

PREV DISCUSSION... /ISSUED 350 PM CDT THU MAR 15 2012/

DISCUSSION...
ANOTHER WARM AND BREEZY DAY ACROSS SOUTHEAST TEXAS AS OUR ONSHORE
FLOW PATTERN CONTINUES. A FEW ISOLATED SHOWERS HAVE POPPED UP THIS
AFTERNOON BUT THESE WILL QUICKLY COME TO AN END BY EARLY EVENING
WITH CLOUD COVER INCREASING AS WE GO THROUGH THE EVENING HOURS.

THE PERSISTENT PATTERN OF ONSHORE FLOW NEAR THE SURFACE AND WEST
SOUTHWESTERLY FLOW ALOFT WILL CONTINUE FOR THE NEXT SEVERAL DAYS.
BY SUNDAY AN UPPER LEVEL TROUGH WILL BEGIN TO DEEPEN ACROSS THE
PACIFIC NORTHWEST AND DIG SOUTHWARD INTO THE SOUTHWESTERN UNITED
STATES. AS THIS SYSTEM APPROACHES LOW LEVEL FLOW WILL STRENGTHEN
AND RAIN CHANCES SHOULD INCREASE SLIGHTLY FOR SUNDAY AND MONDAY
WITH SHOWERS BECOMING MORE WIDESPREAD.

MODELS STILL IN VERY LOOSE AGREEMENT WITH THE STRENGTH AND TIMING
OF THIS SYSTEM. BOTH THE GFS AND ECMWF HAVE THE TROUGH AXIS ACROSS
THE FOUR CORNERS REGION BY TUESDAY MORNING AND BRING THE UPPER LOW
INTO THE TEXAS PANHANDLE BY WEDNESDAY. AS THIS SYSTEM APPROACHES
IT WILL PUSH A PACIFIC COLD FRONT INTO OUR REGION. WHILE IT
REMAINS WELL INTO THE EXTENDED PERIOD OF THE FORECAST IT DOES
APPEAR THAT BOTH THE GFS AND ECMWF WOULD SUPPORT THE POTENTIAL FOR
HEAVY RAINFALL AND SOME SEVERE THUNDERSTORMS ACROSS SOUTHEAST
TEXAS ON TUESDAY AND WEDNESDAY AHEAD OF THIS SYSTEM. FOR NOW WE
WILL HAVE TO KEEP AN EYE ON THE TRACK OF THE LOW AND REFINE THE
SEVERE THREAT FURTHER AS WE GET CLOSER TO THE EVENT. 38

MARINE...
HIGH PRESSURE OVER THE EASTERN SEA BOARD WILL CONTINUE TO SUPPORT
SOUTHERLY WINDS OVER THE NW GULF AND UPPER TX COAST.  WINDS ARE
EXPECTED TO INCREASE SUNDAY AND MONDAY AS AN AREA OF LOW PRESSURE
DEEPENS IN THE PLAINS.  STRONG SE WINDS WITH A LONG FETCH ACROSS THE
GULF WILL SUPPORT BUILDING SEAS TO ROUGH LEVELS.  SMALL CRAFT
ADVISORIES MAY BE REQUIRED FOR THE OFFSHORE WATERS SUN NIGHT THROUGH
THE MIDDLE OF THE WEEK. A FRONT IS EXPECTED TO PUSH OFF THE COAST
LATE WED INTO THUR WHICH WILL TURN WINDS TO THE WEST AND NORTHWEST.
