AREA FORECAST DISCUSSION...UPDATED

646 AM CDT WED MAY 4 2011

.DISCUSSION...SEE AVIATION SECTION FOR 12Z TAF ISSUANCE.

&&

.AVIATION...LIGHT NORTHEAST WINDS WILL DEVELOP THIS MORNING...
SLOWLY BECOMING EAST LATER IN THE DAY. FEW TO SCT HIGH CLOUDS ARE
MOVING OVERHEAD FROM THE SOUTHWEST...HINTS OF EAST PACIFIC
MOISTURE LIFTING OVER THE MOUNTAINS IN NORTH CENTRAL MEXICO. AN
ELEVATED ISOTHERMAL LAYER MAY RESULT IN VFR CEILINGS LATER TODAY
AND TONIGHT...ONCE NORTHEAST TO EAST WINDS INCREASE...WITH OPEN
CELL CU OVER THE GULF TO THE EAST INDICATIVE OF AVAILABLE
MOISTURE.

&&

.PREV DISCUSSION... /ISSUED 341 AM CDT WED MAY 4 2011/

SHORT TERM /TODAY THROUGH THURSDAY/...THE SURFACE RIDGE NOW
CENTERED OVER THE EASTERN HALF OF THE LOWER 48 STATES WILL SHIFT
STEADILY EAST THROUGHOUT TODAY AND WED. THIS WILL ALLOW THE WAA AND
THE LOW LEVEL DEW POINTS TO STEADILY INCREASE AS THE LOW LEVEL FLOW
STARTS TO ADVECT IN MORE HUMID AIR FROM OFF OF THE GULF OF MEX. AS
THE WAA AND MOISTURE ADVECTION INCREASES EXPECT THE MAX AND MIN
TEMPS WILL BE ON THE INCREASE THROUGH THURSDAY. MAV AND MET FORECAST
MAX AND MIN TEMPS ARE IN PRETTY CLOSE AGREEMENT AND WILL GO CLOSE TO
NUMERICAL GUIDANCE FOR MINS AND WILL GO SLIGHTLY ABOVE GUIDANCE FOR
HIGHS AS EXPECT THE MODEL GUIDANCE MAY BE UNDERESTIMATING THE
OVERALL STRENGTH OF THE WARM UP AND THE OVERALL IMPACT OF DRY SOIL
CONDITIONS ON DAYTIME HEATING.

LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...NOT MUCH IN THE WAY
OF SIGNIFICANT WEATHER IS ANTICIPATED TO EFFECT DEEP SOUTH TX
DURING THE LONG TERM FCST PERIOD. A ZONAL FLOW PATTERN WILL BE THE
DOMINANT UPPER FEATURE ACROSS THE REGION DURING THE BEGINNING OF
THE PERIOD. A WEAK RIDGE IS ANTICIPATED TO DEVELOP ACROSS THE
SOUTHERN PLAINS DURING THE COURSE OF THE UPCOMING WEEKEND AS AN
UPPER LVL LOW DEVELOPS ACROSS THE PAC NW. THIS FEATURE IS PROGGED
TO SLIDE SEWD ACROSS THE GREAT BASIN AND INTO THE FOUR CORNERS
REGION LATE IN THE WEEKEND INTO EARLY NEXT WEEK. AT THE SFC...HIGH
PRESSURE WILL MAINTAIN CONTROL ACROSS THE GULF OF MEXICO AS A
SERIES OF LOW PRESSURE SYSTEMS BEGIN TO TAKE UP RESIDENCE FROM THE
SOUTHERN PLAINS AND WEST TX SWD INTO NORTHERN MEXICO DURING THE
COURSE OF THE WEEKEND THRU THE END OF THE PERIOD.

THIS PATTERN WILL HELP TO PROMOTE A MORE ENHANCED ONSHORE FLOW
WITH TIME WITH WARMER AND INCREASINGLY MORE BREEZY CONDITIONS
DURING THE MIDDLE TO LATTER HALF OF THE PERIOD. ANTICIPATE MOSTLY
CLOUDY TO OVERCAST SKIES THRU THE EARLY MRNG HRS DURING THE PERIOD
WITH INCREASING AMOUNTS OF SUNSHINE POSSIBLE DURING THE DAYTIME
HRS. THE ONSHORE FLOW WILL ALLOW THE HUMIDITY TO RETURN ALLOWING
LOW TEMPS TO GO BACK ABOVE NORMAL DURING THE WEEKEND INTO EARLY
NEXT WEEK. DAYTIME TEMPERATURES WILL ALSO WARM WITH FAIRLY HOT
READINGS EXPECTED DURING THAT SAME TIME PERIOD. RAINFALL CHANCES
LOOK TO BE VERY SPARSE IF NOT NIL THRU THE ENTIRE PERIOD.

MARINE...TODAY THROUGH THURSDAY...THE SURFACE RIDGING OVER THE
EASTERN HALF OF THE COUNTRY WILL MAINTAIN A MODERATE PGF IN PLACE
OVER THE LOWER TX BAY AND GULF WATERS. THIS WILL ALLOW THE ELEVATED
GULF SWELLS TO DIMINISH SLOWLY IN THE SHORT TERM AS THE SURFACE FLOW
GRADUALLY SHIFTS AROUND FROM THE E-SE LATER IN THE CWF PERIOD. WILL
MENTION SCEC WORDING FOR THE GULF WATERS AS BUOY020 REPORTS SWELLS
AROUND 6 FT AND A ENE WIND FROM 15G20KTS.

THURSDAY NIGHT THROUGH SUNDAY...FAVORABLE MARINE CONDITIONS WILL
EXIST FOR THE MOST PART DURING THE BEGINNING OF THIS FORECAST
PERIOD ACROSS THE LWR TX COASTAL WATERS. SFC HIGH PRESSURE WILL
MAINTAIN CONTROL ACROSS THE NORTHWEST GULF OF MEXICO THRU FRIDAY.
LIGHT TO MODERATE EASTERLY FLOW WILL PERSIST EARLY IN THE PERIOD
AND BEGIN TO VEER WITH TIME ON FRIDAY. LIGHT TO MODERATE WINDS AND
LOW TO MODERATE SEAS ARE EXPECTED THRU THE BEGINNING OF THE
WEEKEND. THE ONSHORE FLOW WILL STRENGTHEN DURING THE WEEKEND WHICH
WILL ALLOW FOR UNSETTLED CONDITIONS TO DEVELOP. THE LOCAL PRESSURE
GRADIENT WILL BEGIN TO TIGHTEN THE LATTER HALF OF SATURDAY AND
PREVAIL THRU SUNDAY AS LOW PRESSURE DEVELOPS FROM THE PLAINS
SOUTHWARD INTO NORTHERN MEXICO. SE WINDS ARE EXPECTED TO BE
STRONGER DURING THE WEEKEND WHICH WILL HELP TO CHURN UP SEAS. SCA
CONDITIONS WILL BE POSSIBLE ACROSS ALL OR PORTIONS OF THE MARINE
AREAS DURING THE WEEKEND.
