AREA FORECAST DISCUSSION...UPDATED FOR AVIATION
NATIONAL WEATHER SERVICE FORT WORTH TX
541 PM CST MON NOV  1 2004

.AVIATION...
CURRENT TAFS LOOK PRETTY GOOD SO HAVE KEPT MOST IN TACK.
HOWEVER...CONVECTION OUT WEST HAS PROMPTED US TO INCLUDE A TEMPO FOR
TSRA 04-07Z. PRETTY MUCH MVFR WITH OCCASIONAL IFR NEXT 24 HOURS.

&&

.SHORT TERM...
FCST TO BE TRICKY THROUGH TUES...POSSIBLY TUES NIGHT ON ALL FRONTS
AS NM/CO UPPER LOW/TROUGH SLIDES ENEWD ACROSS W TX TONIGHT...THEN
ACROSS THE RED RIVER VALLEY/SRN OK INTO TUES NIGHT. MEANWHILE...COLD
FRONT IS STILL ONLY MAKING SLOW PROGRESS SEWD AS PRESSURE FALLS/SW
FLOW ALOFT OCCURRING AHEAD OF UPPER LOW KEEPS THE FRONT IN CHECK
THROUGH ABOUT 02Z. AS UPPER LOW MOVES INTO W TX TONIGHT/ELECTION
DAY...DEEPER BAROCLINICITY SHOULD HELP ADVANCE FRONT THROUGH ALL OF
CWA BY MIDDAY TUESDAY. THOUGH BEST PWAT (=>1.5 IN) REMAINS ALONG/E
OF I-35...SHOULD EXPECT RAIN BREAKING OVER OVER W TX TO CONTINUE
SLOWLY SPREADING ENE INTO N TX LATER TONIGHT. ISOLD...LOW END SVR
STORMS WITH DIME TO NICKEL HAIL CANT BE RULED OUT WEST-NORTH OF
D/FW TONIGHT...AS MID LVL LAPSE RATES INCREASE. MOST OF ACTIVITY
HOWEVER SHOULD BE IN THE FORM OF SHOWERS/RAIN WITH EMBEDDED THUNDER
FROM TIME TO TIME AS BEST LIFT OCCURS BEHIND IMPENDING COLD FRONT.
LOOK FOR PATCHY RAIN TO LINGER ELECTION DAY AND TUES NIGHT...AS
UPPER LOW SLOWLY PULLS OUT AND WRAP AROUND MSTR REMAINS. RAIN
CHANCES END BY 12Z WED AS DRIER AIR/SUBSIDENCE ARRIVE ACROSS N TX
AND FLOW ALOFT BECOMES NWLY. WITH THAT SAID...WILL GO LOW END WIND
BEHIND FRONT IN CAA/TIGHT PRESSURE GRADIENT...BUT NO WIND ADVISORY
TO BE ISSUED ATTM. ALSO...TEMP FCSTS WILL BE DIFFICULT WITH
CLOUDS/PRECIPITATION AND EVENTUAL CAA...LENDING TO LOW DIURNAL RANGE
EXPECTED ON TUES.

&&

.LONG TERM...
DEFINITELY MORE LIKE EARLY NOVEMBER CLIMATOLOGICALLY SPEAKING FOR
THE REMAINDER OF THE WORK WEEK AS REINFORCING SHOT OF POLAR AIR
SNEAKS IN BY THURS WITH HIGHS HARD PRESSED TO GET OUT OF THE 60S.
SOME MODIFICATION OF TEMPS HEADING INTO NEXT WEEKEND AS UPPER LVL
PATTERN DEAMPLIFIES...BUT TO WHAT EXTENT IS IN QUESTION WITH MUCH
UNCERTAINTY DEPICTED AMONGST THE MODELS.
