AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
255 PM CST WED NOV 14 2007

.DISCUSSION...
IT TOOK SOME TIME...BUT THE SUN FINALLY HAS BROKEN OUT HERE ACROSS
MUCH OF NORTHERN ALABAMA. AFTERNOON RADAR SHOWS SEVERAL
THUNDERSTORMS...A COUPLE SEVERE...OVER NORTHERN MIDDLE TENNESSEE...
WITH ADDITIONAL ACTIVITY BEGINNING TO BUILD NEAR PICKWICK LAKE.
AFTERNOON TEMPERATURES HAVE WARMED INTO THE 70S AREAWIDE...DESPITE
SOME EARLIER CLOUDS AND RAIN. DEWPOINTS HAVE CLIMBED INTO THE
MUGGY-FOR-NOVEMBER MIDDLE 60S.

A BIG WEATHER CHANGE IS ON THE WAY...AND TONIGHT IS STARTING TO LOOK
LIKE OUR ONLY RAIN CHANCE UNTIL THANKSGIVING.

VERY SHORT TERM (TONIGHT)...
WITH THE ABUNDANT MOISTURE AND WARM TEMPS IN PLACE...AND THE AIRMASS
CLASH MOVING TOWARD THE REGION...SHOWERS AND THUNDERSTORMS ARE
ALREADY DEVELOPING AND WILL CONTINUE TO SPARK ALONG AND AHEAD OF THE
FRONT AS IT PROGRESSES EASTWARD. THE FRONT IS CURRENTLY EXPECTED TO
REACH THE NORTHWESTERN TIP OF ALABAMA JUST AFTER SUNSET...AND MAKE A
STEADY MARCH EAST AND SOUTHEAST...REACHING DEKALB COUNTY JUST BEFORE
MIDNIGHT. THE NSSL WRF CENTERED ON HUN ACTUALLY SHOWS A GOOD
PROGRESSION OF THIS AND IT WAS USED UNTIL ITS FORECAST RUN ENDS AT
12Z THURSDAY.

SEVERE WEATHER POTENTIAL IS THERE...CAPE IS ABOUT 1000 J/KG BASED
OFF THE 21Z NAM BUFR SOUNDING...BUT THE WINDOW FOR SEVERE SEEMS
PRETTY SHORT...PROBABLY BETWEEN NOW AND 7 OR 8 PM THIS EVENING.
THREAT IS MOST EVIDENT IN THE SHOALS...WHERE THE FRONT WILL BE
CLOSEST BEFORE THE LOSS OF DAYTIME HEATING...AND THIS IS THE REGION
UNDER A SVR TSTM WATCH UNTIL 8 PM TONIGHT.

SEEMS LIKE LITTLE DOUBT THAT WE WILL SEE RAIN TONIGHT...AND I WENT
WITH 100 POP JUST ABOUT EVERYWHERE...EXCEPT THE EXTREME NW CORNER
WHERE THE FRONT MIGHT ALREADY BE THROUGH AND EVERYTHING DONE.

TEMPS WILL FALL SHARPLY BEHIND THE FRONT...BUT AS WITH MOST
POST-FRONTAL NIGHT SITUATIONS...I STAYED ON THE HIGH SIDE OF
GUIDANCE SINCE THE MODELS TEND TO OVERDO THE COOLING ON NIGHT ONE.

OTHER KEY TONIGHT IS WINDS. GUSTY GRADIENT WINDS ARE EXPECTED NEAR
THE FRONT. THE NSSL WRF SHOWS A BRIEF PERIOD OF SUSTAINED WINDS OF
20 TO 25 MPH...WITH GUSTS UP TO 35 MPH...AROUND THE TIME OF FRONTAL
PASSAGE. SINCE THE DURATION IS EXPECTED TO ONLY BE A COUPLE HOURS...
WILL ADVISE THE ONCOMING SHIFT AND LIKELY WE WILL HANDLE IT WITH SPS
PRODUCTS / SIGNIFICANT WEATHER ALERTS.

REMAINDER OF FORECAST (TOMORROW THROUGH NEXT WEDNESDAY)...
SKIES WILL RAPIDLY CLEAR LATE TONIGHT OR EARLY TOMORROW. STILL LOOKS
LIKE SOME INSTABILITY CUMULUS CLOUDS ON THURSDAY. PLENTY OF COLD
ADVECTION THOUGH SO TEMPERATURES WILL STRUGGLE TO GET BACK ABOVE 50
ON THURSDAY IN MANY AREAS. I DOUBT MANY WILL GET ABOVE 55 DEGREES.

AGAIN WINDS WILL BE AN ISSUE THURSDAY DUE TO THE STRONG HIGH
PRESSURE BUILDING IN BEHIND THE FRONT. LOOKING AT SUSTAINED WINDS OF
15 TO 25 MPH WITH GUSTS OVER 30 ESPECIALLY IN THE MOUNTAINS.
REACHING OUR WIND ADVISORY CRITERIA IS MARGINAL (25 MPH FOR 3 HOURS
OR GUSTS TO 35 MPH) SO I WILL HOLD OFF AND LET THE NIGHT SHIFT
ASSESS WHETHER ONE IS NECESSARY. VERY IMPORTANT TO NOTE REGARDLESS
THAT THESE WIND EVENTS...WHILE NOT SEVERE...WILL BE ENOUGH TO CAUSE
SOME FALLEN TREES...ESPECIALLY THOSE WEAKENED BY THE LONG-TERM
DROUGHT.

SKIES CLEAR BY THURSDAY NIGHT AND WITH DEWPOINTS IN THE 20S...A
FREEZE IS LOOKING INCREASINGLY LIKELY...WITH ANOTHER HARD FREEZE
POSSIBLE. SUNNY SKIES HOLD THROUGH FRIDAY AND IT STAYS SEASONABLY
COOL FOR THE END OF THE WEEK.

OVER THE WEEKEND...SOUTHERLY FLOW RESUMES. IN FACT...SOUTHWESTERLY
WINDS ARE PROGGED FOR SATURDAY WHICH WILL BE A VERY QUICK-WARMING
WIND. HIGHS SHOULD REACH INTO THE 60S AFTER A START CLOSE TO
FREEZING. I AM STILL NOT TOTALLY CONVINCED WE WILL STAY DRY AS THE
GFS INDICATES (THE ECMWF HAS BEEN CONSISTENTLY SHOWING A CHANCE OF
RAIN OVER THE WEEKEND IN ASSOCIATION WITH AN INVERTED TROF). BUT
CONFIDENCE IN IT...ESPECIALLY DURING AN ONGOING EVENT...IS NOT HIGH
ENOUGH TO PUT THE RAIN CHANCE BACK IN.

EARLY NEXT WEEK...WINDS COME BACK AROUND AS HIGH PRESSURE REMAINS TO
OUR NORTH. THIS WILL LIKELY KEEP CONDITIONS DRY THROUGH THE FIRST
HALF OF THE WEEK...WITH HIGHS IN THE MID 60S AND LOWS IN THE 40S.

INTERESTING TO NOTE THE 12Z GFS STALLING A FRONT NEAR OUR AREA
THROUGH THE THANKSGIVING WEEKEND. YES I KNOW IT IS THE HOLIDAY BUT
WE SO DESPERATELY NEED THE RAIN...LETS CROSS OUR FINGERS AND HOPE.

EAST OF INTERSTATE 65 STILL DO HAVE THE POTENTIAL TO SEE SEVERE
WEATHER.

THE THUNDERSTORM THREAT WILL DIMINISH OVERNIGHT BEHIND THE COLD
