AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
416 AM CDT SAT MAY 28 2011

.SHORT TERM /TODAY THROUGH SUNDAY/...A LARGE MID LEVEL CLOSED LOW
MOVING INTO THE PACIFIC NORTHWEST WILL CONTINUE TO DIG SOUTHEAST
MOVING INTO THE NORTHERN ROCKIES BY SUNDAY. THIS WILL IN TURN RESULT
IN A SURFACE LOW PRESSURE SYSTEM DEVELOPING OVER THE CENTRAL PLAINS
STATES THIS HOLIDAY WEEKEND. THIS HAS TIGHTENED UP THE PGF WHICH
WILL RESULT IN BREEZY TO WINDY CONDITIONS ON INTO SUNDAY. WILL POST
A WIND ADVISORY FOR THE EASTERN HALF OF THE BRO CWA AS THE CURRENT
VWP FROM THE KBRO RADAR SHOWS A PRETTY STRONG SOUTHERLY LLJ IN PLACE
OVER THE REGION IN THE 40 TO 50 KT RANGE FROM JUST OFF OF THE
SURFACE EXTENDING UP TO NEAR 4 KFT. THE 00Z BRO SOUNDING SHOWS A
PRETTY DRY AND SUBSIDENT AIRMASS IN PLACE OVER THE REGION WITH A
PWAT OF ONLY 1.25 INCHES. AS THE MID LEVEL RIDGING STEADILY BUILDS
OVER THE AREA IN THE SHORT TERM EXPECT GENERALLY CLR SKIES AND HOT
CONDITIONS TO CONTINUE. FOR TEMPS WILL GO CLOSE TO THE MAV NUMBERS
FOR MINS AND THE MET NUMBERS FOR MAXES AS THE NAM GUIDANCE
CONTINUES TO MAINTAIN A BETTER HANDLE ON THE EARLY SUMMERTIME
CONDITIONS. ALTHOUGH THE HEAT INDICES WILL REMAIN PRETTY ELEVATED
FOR THE HOLIDAY WEEKEND THEY SHOULD REMAIN BELOW ADVISORY LEVELS
AT THIS TIME.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...THIS FORECAST PERIOD
WILL BE RESEMBLE MUCH LIKE THE PREVIOUS SEVERAL DAYS IN THAT MORE
HEAT AND MORE DRY CONDITIONS ARE EXPECTED TO PREVAIL ACROSS DEEP
SOUTH TEXAS. MID LVL RIDGE OF HIGH PRESSURE WILL CENTERED ACROSS THE
DEEP SOUTH AND APPALACHIANS BY THE END OF THE WEEKEND. THIS RIDGE
WILL NOSE BACK SWWD ACROSS SOUTH TX INTO NORTHERN MEXICO. STEPPING
THROUGH TIME...THIS RIDGE WILL RETROGRADE WWD AND BECOME CENTERED
ACROSS THE SOUTHERN PLAINS BY THE END OF THE PERIOD. AT THE
SURFACE...LEE SIDE LOW PRESSURE WILL BE SLIDING NWD TWD THE
NORTHERN PLAINS EARLY IN THE FCST TERM. HIGH PRESSURE ACROSS THE
SE UNITED STATES WILL BECOME MORE ESTABLISHED OVER THE NORTHERN GULF
OF MEXICO AND SE TEXAS. THIS PATTERN WILL BASICALLY MEAN A
CONTINUATION OF WHAT WE HAVE ALL BEEN ACCUSTOMED TO SEEING. WARMER
THAN NORMAL TEMPERATURES IN THE 90S CAN BE EXPECTED EACH DAY WITH
OVERNIGHT LOWS ONLY FALLING INTO THE 70S TO AROUND 80 DEGREES.
THERE IS A HINT OF A SLIGHT PATTERN SHIFT BY ABOUT THE MIDDLE OF
THE WEEK AS THE SFC AND UPPER LVL FEATURES RE-ORIENT AND ALLOW MORE
OF AN EAST TO NORTHEAST FLOW TO DEVELOP. THIS MAY BRING SLIGHTLY
COOLER TEMPERATURES INTO THE AREA. HOWEVER...THE FCST WILL NOT
REFLECT ANY NOTICEABLE CHANGES IN TEMPERATURE...OUTSIDE OF MAX
TEMPS IN THE 100S ACROSS OUR WESTERN ZONES DROPPING DOWN INTO THE
90S.

&&

.MARINE...TODAY THROUGH SUNDAY...AS THE PGF TIGHTENS STEADILY INTO
THE WEEKEND THE WINDS AND SEAS WILL RESPOND ACCORDINGLY PERSISTING
IN SCA LEVELS ACROSS THE GULF WATERS IN THE SHORT TERM. CURRENTLY
BUOY020 IS VERIFYING THE GULF SCA NICELY WITH SE WINDS AT 20G25KTS.
THE CURRENT GULF SWELLS ARE JUST BELOW SCA LEVELS BUT HAVE BEEN
STEADILY BUILDING THROUGHOUT THE NIGHT. CONDITIONS ACROSS THE LAGUNA
MADRE SHOULD DEGRADE LATER THIS MORNING REACHING INTO SCA LEVELS
PRETTY QUICKLY. EXPECT THE GULF CONDITIONS TO ALSO STEADILY DEGRADE
AS THE STRONG PGF CONTINUES FROM THE CENTRAL PLAINS SURFACE LOW. SO
HAVE EXTENDED THE SCA FOR THE GULF ON INTO THE OVERNIGHT PERIODS
TONIGHT.

SUNDAY NIGHT THROUGH WEDNESDAY...MARINE CONDITIONS WILL CONTINUE
TO REMAIN UNFAVORABLE DURING THE BEGINNING OF THIS FORECAST PERIOD
AS A MODERATE TO STRONG ONSHORE FLOW PREVAILS. A TIGHT PRESSURE
GRADIENT WILL ALLOW SOUTHERLY WINDS TO REMAIN MODERATE TO STRONG
AND OCCASIONALLY GUSTY. BAY WATERS WILL REMAIN CHOPPY INTO MONDAY
BEFORE IMPROVING AND SEAS WILL CONTINUE TO BE ELEVATED RIGHT
THROUGH MONDAY INTO EARLY TUESDAY. EXPECT SCA CONDITIONS WILL BE
PROBABLY ACROSS ALL MARINE AREAS SUNDAY NIGHT INTO MONDAY. THE
GRADIENT WILL BEGIN TO RELAX BY THE END OF THE PERIOD AS SURFACE
HIGH PRESSURE MOVES ACROSS THE NORTHERN GULF COAST. FAVORABLE
CONDITIONS WILL DEVELOP ACROSS THE LAGUNA MADRE AND NEARSHORE GULF
WATERS TUESDAY INTO WEDNESDAY WITH ELEVATED SEAS PERSISTING WELL
OFFSHORE WEDNESDAY.

&&

.FIRE WEATHER...AM CONCERNED ABOUT THE DRY AND WINDY CONDITIONS
ACROSS THE FAR WESTERN THREE COUNTIES THIS AFTERNOON. THE
COMBINATION OF THE MIN RH VALUES AND THE 20 FT WINDS WILL PUSH
CONDITIONS UP CLOSE TO RED FLAG WARNING CRIT. ALTHOUGH THIS IS A
MORE BORDERLINE EVENT FOR THE REGION WILL GO AHEAD AND POST AND RFW
FOR THE AFTERNOON HOURS TODAY.
