AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE BROWNSVILLE TX
856 PM CDT SUN APR 29 2012

.DISCUSSION...UPDATED RESPECTIVE PRODUCTS FOR THE EXPIRATION OF
THE RIP CURRENT STATEMENT AND THE LAGUNA MADRE SMALL CRAFT
ADVISORY AS WINDS AND SEAS DECREASE.

&&

.PREV DISCUSSION... /ISSUED 657 PM CDT SUN APR 29 2012/

DISCUSSION...UPDATED FOR LATEST AVIATION DISCUSSION BELOW.

AVIATION...CURRENT SATELLITE IMAGERY AND SURFACE OBSERVATIONS
INDICATE VFR CONDITIONS ACROSS DEEP SOUTH TEXAS THIS EVENING...
EXCEPT FOR MVFR CONDITIONS AT BRO AND PIL WITH CEILINGS BETWEEN
2200 TO 2800 FEET. MVFR CEILINGS ARE LIKELY ACROSS THE AREA
TONIGHT WITH CEILINGS LOWERING TO AROUND 1500 FEET BY LATE
TONIGHT. THE LOW CLOUDS WILL BE RATHER SLOW IN MIXING OUT ON
MONDAY WITH MVFR CONDITIONS EXPECTED TO CONTINUE TO AROUND 18Z
MONDAY. SOUTHEAST WINDS GUSTING 20 TO 25 KNOTS WILL RETURN MONDAY
MORNING.

PREV DISCUSSION... /ISSUED 144 PM CDT SUN APR 29 2012/

SHORT TERM.../TODAY THROUGH MONDAY NIGHT/...PERSISTENT SOUTHEAST FLOW
CONTINUES WITH A SURFACE RIDGE OVER THE NORTHEASTERN GULF OF MEXICO
AND AN UPPER TROUGH OVER THE ROCKY MOUNTAIN REGION EXTENDING TO THE
SURFACE IN THE FORM OF A DEVELOPING SURFACE CYCLONE OVER THE CENTRAL
PLAINS AND LEE TROUGHING EAST OF THE ROCKIES AND THE SIERRA MADRE. A
STRONG SUBSIDENCE INVERSION EXISTS AROUND 750 MB.

LITTLE CHANGE IS ANTICIPATED SYNOPTICALLY OVER THE NEXT 24
HOURS...WITH THE LONE EXCEPTION POSSIBLY BEING THE STRENGTH OF
SURFACE RIDGING IN THE EASTERN GULF BEING REDUCED BY AN UPPER LEVEL
LOW MOVING OFF THE EAST COAST OF FLORIDA. THIS MAY LESSEN OUR WINDS
TOMORROW A MPH OR TWO...BUT BASICALLY THE SAME OVERALL INGREDIENTS
ARE EXPECTED WITH WARM WINDY AFTERNOON CONDITIONS...AND PERHAPS A
LITTLE MORE CLOUD COVER.

A WEAK APPROACHING SHORTWAVE WILL MAKE AN EFFORT OF REDUCING THE CAP
ENOUGH TO AID IN CONVECTIVE DEVELOPMENT...BUT IS NOT EXPECTED TO
SUCCEED FOR NOW IN ALL BUT THE FAR NORTHWEST WHERE DIVERGENCE IS
PROGGED TO BE THE BEST. HAVE ADDED SCHC THUNDER POPS THERE. GFS IS
MORE AGGRESSIVE WITH ERODING THE CAP WHERE THE NAM SURGES THE MARINE
LAYER IN ENOUGH TO PREVENT US FROM REACHING CONVECTIVE TEMPERATURE
AND IS NOT AS AGGRESSIVE WITH MID LEVEL COOLING...SO WENT A BIT IN
THE MIDDLE WITH SOME MID LEVEL COOLING AND A LESS AGGRESSIVE MARINE
LAYER INTRUSION. TEMPS REMAIN ABOVE MAV/MET CONSENSUS.

LONG TERM.../TUESDAY THROUGH SUNDAY/...MORE OF THE SAME EXPECTED
IN THE EXTENDED FORECAST. LIGHT SOUTHWEST FLOW ALOFT WITH WEAK
EMBEDDED SHORT WAVES TO TRAVERSE ACROSS THE AREA ALL WEEK. THE MOST
SIGNIFICANT DISTURBANCE TO MOVE ACROSS THE REGION THU NIGHT AND
FRI. THIS COULD SET OF AN ISOLATED SHOWER OR TWO...AND IS WORTH
MONITORING OVER THE NEXT FEW DAYS. TEMPS TO REMAIN A BIT ABOVE
NORMAL...WITH 90S ACROSS INLAND AREAS EACH DAY WHICH MAY APPROACH
100 IN ZAPATA COUNTY. LOW TO MID 80S ALONG THE COAST. BY
SATURDAY...THE SOUTHWEST FLOW ALOFT WILL TRANSITION TO LIGHT
NORTHWESTERLY AND THEN VARIABLE AS A MID LEVEL RIDGE SETS UP
OVERHEAD. MAX TEMPERATURES MAY CREEP UP A FEW DEGREES SAT AND SUN
DUE TO THE STRONGER SUBSIDENCE. NO FRONTAL SYSTEMS ANTICIPATED
OVER THE NEXT 7 DAYS AS THE SOUTHEAST SURFACE FLOW WILL PERSIST.
WITH NO STRONG CYCLOGENESIS ANTICIPATED ACROSS THE PLAINS THIS
WEEK WINDS SHOULD REMAIN IN CHECK RESULTING IN FAIRLY LIGHT WINDS
DURING THE OVERNIGHT AND EARLY MORNING HOURS AND MODERATE WINDS
DURING THE AFTERNOON.

MARINE...TODAY THROUGH MONDAY NIGHT...SMALL CRAFT ADVISORIES REMAIN
IN EFFECT FOR THE LAGUNA MADRE THROUGH EARLY THIS EVENING AND FOR
THE COASTAL WATERS UNTIL EARLY MONDAY MORNING. SOUTHEAST WINDS ARE
EXPECTED TO PERSIST THROUGH THE DAY MONDAY AND SMALL CRAFT
ADVISORIES ARE AGAIN POSSIBLE MONDAY...BUT ARE NOT AS LIKELY AS
THEY HAVE BEEN THE PAST FEW DAYS. MODERATE WINDS AND SEAS ARE
EXPECTED MONDAY NIGHT.

TUESDAY THROUGH FRIDAY...GENERALLY FAVORABLE MARINE CONDITIONS
EXPECTED FOR MOST OF REMAINDER OF THE WEEK. SOUTHEAST SURFACE FLOW
SHOULD STAY BELOW 20 KNOTS WITH THE STRONGEST WINDS EXPECTED IN THE
AFTERNOON HOURS. TWO TO FIVE FOOT SEAS EXPECTED THROUGHOUT THE
EXTENDED PERIOD. A WEAK DISTURBANCE COULD SET OFF A SHOWER OR TWO
THURSDAY NIGHT OR FRIDAY...BUT CHANCES AT THIS POINT REMAIN LESS
THAN 20 PERCENT.
