AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
819 PM CST WED DEC 23 2009

.DISCUSSION...THE COLD FRONT HAS CLEARED THROUGH THE DRT AREA
WITH THE LATEST DRT OB REPORTING A NW WIND OF 20G31KTS. THE
LATEST RADAR REFLECTIVITY SHOWS AREAS OF LIGHT TO MODERATE SHOWERS
DEVELOPING IN THE POST FRONT ENVIRONMENT WITH SOME EMBEDDED
T-STORMS LOCATED FURTHER NORTH NEAR ABI. MEANWHILE TO THE
NORTHEAST STG/SVR CONV CONTINUES TO FIRE OVER EAST TX MOVING
NORTH. RIGHT NOW EXPECT THE COLD FRONT TO PUSH INTO THE WESTERN
PORTIONS OF THE BRO CWA AFTER MIDNIGHT TONIGHT EVENTUALLY CLEARING
THE BRO AREA AROUND SUNRISE TOMORROW MORNING. THE 00Z BRO SOUNDING
CONTINUES TO SHOW A FAIRLY DRY AND STABLE AIRMASS OVER THE REGION
WITH A PWAT < ONE INCH AND A CAPE OF ONLY 261 J/KG. THE LIMITED
MOISTURE AND INSTABILITY SHOULD LIMIT THE AMOUNT AND STRENGTH OF
ANY CONV FORMATION WITH THE FROPA. FOR NOW EXPECT THE BEST CONV
CHCS TO REMAIN LIMITED TO THE IMMEDIATE COASTAL COUNTIES AND THE
LOWER TX BAY AND GULF WATERS. THE MAIN CONCERN THROUGH TOMORROW
WILL BE THE ANTICIPATED SHIFT AND INCREASE IN THE SURFACE WINDS
AFTER THE FRONT. EXPECT THE STRENGTH AND DURATION OF THE STRONG
NORTHWEST POST FRONTAL FLOW TO BE ENOUGH TO WARRENT A WIND
ADVISORY FOR EARLY TOMORROW. WILL BE UPDATING THE FORECAST SHORTLY
TO MENTION THIS. OTHERWISE THE CURRENT WORDING LOOKS ON TRACK WITH
NO OTHER MAJOR CHANGES NEEDED.
&&

.AVIATION...WINDS ARE EXPECTED TO REMAIN LIGHT THIS EVENING TO
AROUND MIDNIGHT BUT LOW LEVEL WIND SHEAR MAY POSE A SLIGHT PROBLEM
OVER THE EASTERN REGIONAL AIRPORTS. A STRONG COLD FRONT IS EXPECTED
TO MOVE ACROSS DEEP SOUTH TEXAS REACHING KMFE AROUND 430AM AND KHRL
AROUND 5AM AND KBRO BY 6AM. NORTHWEST WINDS OF 25 TO 34 KNOTS WITH
GUSTS AS HIGH 40 KNOTS ARE LIKELY AS FRONT PASSES AND POSSIBLY
LINGER UNTIL 9 AM THEN SUSTAINED WIND OF 20 TO 25 KNOT AND GUSTS TO
35 KNOTS THE REST OF THE MORNING. IFR TO LOW MVFR CIGS WILL
ACCOMPANY THE FRONTAL BOUNDARY WITH A LOW CHANCE OF SHOWERS OR RAIN.
THEN EXPECT RAPID CLEARING. FAIR FLYING CONDITIONS ANTICIPATED FOR
CHRISTMAS DAY WITH MVFR CIGS RETURNING TO SOUTHERN AREAS OF DEEP
SOUTH TEXAS FRIDAY AFTERNOON.

WEST TEXAS IS FORECAST TO BARREL THROUGH THE LOWER TEXAS COASTAL
WATERS BETWEEN 3 AND 7 AM THURSDAY MORNING. SOUTH TO SOUTHWEST
WINDS COULD INCREASE A FEW HOURS PRIOR TO THE FRONT THEN NORTHWEST
WINDS WILL SURGE AT GALE FORCE RIGHT BEHIND THE FRONT. THE VERY
STRONG WINDS ARE LIKELY TO PERSIST THROUGH THURSDAY MORNING BEFORE

IN PERIODIC STRONG WINDS AND ROUGH SEAS ALONG WITH INCLEMENT
WEATHER.
