AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BROWNSVILLE TX
146 PM CDT SUN MAR 22 2009

.DISCUSSION...MAIN CONCERN IN THE FIRST FEW DAYS OF THE FORECAST
PACKAGE WILL BE THE WIND AND FIRE DANGER IT WILL BRING WITH IT.
THE SECOND HALF CONCERNS WILL BE THE TIMING AND STRENGTH OF A COLD
FRONT WHICH COULD ARRIVE AS EARLY AS FRIDAY AFTERNOON OR AS LATE
AS SATURDAY.

UPPER AIR PATTERN BECOMING PROGRESSIVE WITH A SERIES OF SHORT WAVE
TROUGHS TO TRAVERSE THE U.S. OVER THE NEXT WEEK OR SO...TYPICAL
FOR AN ACTIVE SPRING PATTERN. THIS WILL USHER IN PERIODIC STRONG
WINDS ACROSS THE CWA WITH WARM TO HOT TEMPERATURES IN ADVANCE OF
ANY COLD FRONTS OR DRY LINES THAT TRY TO MAKE INTO THE VALLEY. THE
FIRST OF THE SHORTWAVES IS CURRENTLY OVER THE GREAT BASIN AND WILL
PROGRESS INTO THE ROCKIES ON MONDAY MOVING THROUGH THE PLAINS ON
TUESDAY. PRESSURE GRADIENT TIGHTENS AND LOW LEVEL JET STRENGTHENS
OVER THE NEXT 48 HOURS. A FIRE WEATHER WATCH WILL BE ISSUED FOR
MONDAY MORNING AND AFTERNOON WITH CONFIDENCE IN A WIND ADVISORY
INCREASING. WILL LEAVE NPW ISSUANCE FOR THE MIDNIGHT SO THAT THEY
FINE TUNE THE MAIN AREAS OF CONCERN. WINDS TO REMAIN HEALTHY
MONDAY NIGHT INTO TUESDAY AS THE LOW LEVEL JET REACHES IT MAX
STRENGTHEN DURING THIS PERIOD. WINDS MAY LAY DOWN LATER TUESDAY
AFTERNOON DEPENDING HOW FAR EAST A FRONTAL TROUGH OR DRY LINE
ADVANCES EAST. DRIER AIR BEHIND THIS DRY LINE SHOULD INCREASE THE
FIRE DANGER ON TUESDAY ESPECIALLY OUT WEST AND MAY POSE A GREATER
THREAT FARTHER EAST DEPENDING HOW FAR EAST THE DRY AIR PUSHES.
TEMPERATURES TO INCH UPWARD THE NEXT FEW DAYS AS THE STRONG
SOUTHEAST WINDS VEER SOUTH THE FARTHER WEST YOU GO. HIGH TEMPS TO
BREAK 90 CENTRAL AND WESTERN AREA WITH OVERNIGHT LOWS TO ONLY LOW
INTO THE MID 60S TO NEAR 70 DEGREES. THIS NUMBERS ARE BLEND OF THE
NAM AND GFS MOS GUIDANCE.

AS THE FIRST SHORT WAVE PASSES EAST TUESDAY NIGHT A TRAILING COLD
FRONT LAGS ACROSS THE NORTHERN TIER COUNTIES ON WEDNESDAY. LOW
RAIN CHANCES WERE MAINTAINED ACROSS THE NORTH BUT WERE REDUCED IN
THE SOUTH. NO SIGNIFICANT TEMPERATURES CHANGES ARE ANTICIPATED THE
FRONT LOSES ITS IDENTITY. HOWEVER TEMPERATURES ACROSS THE SOUTHWEST
COULD BECOME VERY WARM WITH 90 DEGREES TO BE BROKEN IN A FEW
LOCATIONS. THURSDAY IS A TRANSITION DAY AS THE NEXT SHORTWAVE
BEGINS TO DIG DOWN THE ROCKIES. THE HOTTEST TEMPERATURES OF THE
WEEK AND BREEZY CONDITIONS ARE ANTICIPATED. THE UPPER TROUGH LOOKS
TO BE A QUICK MOVER WITH THE GFS DEPICTING A 150+ UPPER JET
ASSOCIATED WITH THIS SYSTEM AT 06Z/26. THE GFS AND LOW RES ECMWF
SHOW A FASTER MOVEMENT OF THE COLD FRONT WITH TIMING NOW FRIDAY
AFTERNOON. FRONT LOOKS DRY AT THIS TIME AND MAY PACK A MODEST PUNCH
OF STRONG NORTH WINDS AND MUCH LOWER DEW POINTS. THIS WILL RAISE
THE FIRE WEATHER CONCERN ONCE AGAIN FOR FRIDAY AFTERNOON AND MAYBE
LINGERING INTO SATURDAY. TEMPERATURES MAY FALL BELOW NORMAL BUT DO
NOT EXPECT MUCH IN THE WAY OF CLOUDS SO NEAR NORMAL READINGS CAN
BE EXPECTED. THAT IS ENOUGH FOR NOW.
