NATIONAL WEATHER SERVICE BROWNSVILLE TX
359 AM CST FRI DEC 6 2013

.SHORT TERM /NOW THROUGH SATURDAY/...COLD AIR TO CONTINUE TO SPILL INTO
THE VALLEY THE NEXT 24-36 HOURS. TEMPERATURES ARE LIKELY TO FALL
OR REMAIN STEADY TODAY THEN BEGIN TO FALL AGAIN TONIGHT. SATURDAY
VERY LITTLE DIURNAL RANGE TO TAKE PLACE WITH 30S TO LOW 40S CWA
WIDE. EMPHASIS IS ON WINTER WEATHER HIGHLIGHTS WITH A FREEZE
WARNING FOR THE JIM HOGG...BROOKS AND KENEDY COUNTIES WITH ZAPATA
POSSIBLY BEING ADDED TO THE MIX IN THE NEXT FORECAST UPDATE. A
WIND CHILL ADVISORY WILL COVER THE ENTIRE CWA SHORTLY AFTER
MIDNIGHT AND GO THROUGH SATURDAY MORNING WITH LITTLE LET UP IN THE
BLUSTERY NORTH WINDS. THE NEXT CONCERN WILL BE RAIN/DRIZZLE AND IF
IT MAKES IT FAR ENOUGH NORTH AND WEST. ISENTROPIC LIFT IS BEST
OVER THE COASTAL REACHES AND ACROSS THE LOWER VALLEY WHERE LIGHT
ECHOS ARE SHOWING UP ON RADAR. MODELS SUGGEST THE ISENTROPIC
UPGLIDE STRENGTHENING LATE TONIGHT INTO SATURDAY AS SOUTHERLY FLOW
INCREASES WITH THE APPROACH OF UPPER TROUGH. PRECIPITATION IS
EXPECTED TO SPREAD NORTHWEST AND THIS PUTS THE NORTHERN RANCHLANDS
ON THE FENCE IF FREEZING RAIN/DRIZZLE DEVELOPS. FORECASTER
CONFIDENCE IS LOW AT THIS TIME WITH NOT ALL MODELS IN AGREEMENT.
GFS IS THE MOST BULLISH WITH THE HIGHER POPS. NAM IS INDICATING
LOWER POPS WITH THE ECMWF TRENDING IN BETWEEN BUT MORE LEANING
WITH THE GFS. WILL CONTINUE TO MONITOR THE COLD AIR AND THE LOW
PROBABILITY OF A FREEZING RAIN ADVISORY OR WARNING FOR FREEZING
RAIN/DRIZZLE ACROSS THE NORTHERN ZONES LATE TONIGHT AND SATURDAY
MORNING.

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...ISENTROPIC LIFT
WILL BE ONGOING AT THE START OF THE LONG TERM PERIOD WITH CHANCES
OF LIGHT RAIN AND DRIZZLE MAINLY ALONG AND EAST OF HWY 281. AS IT
STANDS NOW...TEMPERATURES ACROSS BROOKS AND KENEDY COUNTIES WILL
BE ABOVE FREEZING SO NO WINTRY PRECIPITATION EXPECTED. AS SURFACE
LOW PRESSURE DEVELOPS OVER THE WESTERN GULF OF MEXICO...DRIER AIR
WILL WRAP AROUND THE BACKSIDE OF THE SYSTEM WITH PRECIPITATION
CHANCES COMING TO AN END OVER THE WESTERN HALF OF THE AREA SUNDAY
AND MAYBE A FEW PEAKS OF THE SUN BEFORE DUSK. THAT LOW PRESSURE
WILL WEAKEN AS A REINFORCING SHOT OF COLDER AIR WORKS INTO THE
AREA MONDAY. THIS COLD FRONT WILL KNOCK TEMPERATURES DOWN ABOUT 10
DEGREES FROM MONDAY HIGHS IN THE MID 50S TO MID 40S ON TUESDAY.
LIGHT RAIN AND DRIZZLE RETURNS TO THE FORECAST MONDAY AND TUESDAY
FOR THE EASTERN HALF OF THE AREA. FORECAST CONFIDENCE LOWERS AFTER
TUESDAY WITH RESPECT TO A SHORTWAVE ACROSS THE SOUTHWEST CONUS AND
NORTHERN MEXICO. WILL KEEP FORECAST AS IS WEDNESDAY/THURSDAY WITH
WEAK OVERRUNNING AND DRIZZLE ACROSS THE COASTAL COUNTIES AND
COASTAL WATERS.
