AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE HUNTSVILLE AL
845 PM CDT SUN SEP 20 2009
.UPDATE...
ADJUSTED POPS AND LOW TEMPERATURES FOR TONIGHT BASED ON CURRENT
RADAR TRENDS AND OBSERVATIONS.
&&
.DISCUSSION...
A LINE OF SHOWERS AND THUNDERSTORMS CONTINUES TO MOVE ACROSS THE
TENNESSEE VALLEY THIS EVENING BRINGING HEAVY RAINFALL OF UP TO 3
INCHES ACROSS THE AREA. THERE HAVE BEEN A FEW FLASH FLOODING REPORTS
FROM NORTHWEST ALABAMA FROM EARLIER THIS EVENING AND SUSPECT WE WILL
RECEIVE A FEW MORE ACROSS SOUTHERN MIDDLE TENNESSEE BEFORE ITS ALL
SAID AND DONE WITH.
THIS LINE OF THUNDERSTORMS IS IN RESPONSE TO A SURFACE LOW
PRESSURE SYSTEM AND SURFACE TROUGH SITUATED NEAR THE MISSISSIPPI
RIVER. THE LINE OF STORMS ITSELF IS MOVING QUITE SLOW BUT THE
INDIVIDUAL STORMS HAVE BEEN MOVING ABOUT NORTHEAST AT 20-30 MPH.
WITH THAT SAID...THE POTENTIAL FOR HEAVY RAINFALL WILL CONTINUE
OVERNIGHT PARTICULARLY ACROSS AREAS EAST OF INTERSTATE 65. THESE
LOCATIONS ARE WHERE THE HIGHEST POPS ARE FORECAST WITH A
SIGNIFICANT TAPERING OFF OF POPS ACROSS NORTHWEST ALABAMA.
MANY LOCATIONS ACROSS NORTHWEST ALABAMA HAVE LIKELY HIT THEIR LOW
TEMPERATURES FOR TONIGHT AFTER ALL OF THE HEAVY RAINFALL. SO
UPDATED LOWS AND HOURLY TEMPERATURES FOR TONIGHT TO REFLECT THIS
TREND. LOWS TONIGHT WILL RANGE FROM UPPER 60S TO LOWER 70S AREA
WIDE. NO OTHER CHANGES WERE MADE TO THE ONGOING FORECAST AT THIS
TIME.
&&
.AVIATION...
EXPECT -SHRA/TSRA TO IMPACT KHSV AND REDUCE CEILINGS AND VISIBILITIES
FROM 00Z TO 04Z. KMSL CAN EXPECT -SHRA THROUGH 02Z WITH VFR
CEILINGS. MVFR CONDITIONS WILL DEVELOP ACROSS BOTH KMSL AND KHSV
BETWEEN 02-04Z WITH CEILINGS DROPPING TO AROUND 1500 FT BETWEEN
08-10Z. CONDITIONS WILL SLOWLY IMPROVE AS VFR CONDITIONS WILL ONCE
AGAIN DEVELOP BY MONDAY AFTERNOON BARRING ANY -SHRA/-TSRA AT TAF
LOCATIONS. TIMING OF -SHRA AND POSSIBLY -TSRA WILL BE QUITE
DIFFICULT ON MONDAY SO INCLUDED A VCSH FOR NOW.
&&
.PREV DISCUSSION... /ISSUED 220 PM CDT SUN SEP 20 2009/
LONG-AWAITED PATTERN CHANGE IS FINALLY UNDERWAY...AND THAT MEANS
THAT THE RAINY FORECAST IS FINALLY GOING TO SHIFT A LITTLE.
HOWEVER...IN THE SHORT TERM...IT MAY ACTUALLY MEAN MORE RAIN. SFC
LOW HAS BEEN MOVING NORTH/NORTHEAST...AND IS CURRENTLY MOVING UP
THE MID-MISSISSIPPI RIVER VALLEY INTO THE WESTERN GREAT LAKES. A
TRAILING SFC BOUNDARY WILL BE OUR WEATHER MAKER FOR THE NEXT 24
HOURS OR SO BEFORE THINGS BEGIN TO CALM DOWN JUST A BIT.
SHORT TERM (TONIGHT THROUGH TUESDAY)...
WEAK SFC BOUNDARY WILL REMAIN TO THE WEST OF THE AREA...BUT
ACCOMPANYING UPPER LEVEL IMPULSE WILL TRAVERSE THE AREA TONIGHT.
EXPECT SHRA/TSRA WILL BE MORE PREVALENT TONIGHT THAN IN RECENT
NIGHTS...SO WILL CARRY LIKELY POPS. TIMING TRAILING IMPULSES BEHIND
THAT IS A TRICKY PROPOSITION AT BEST...BUT FEEL THAT THERE IS QUITE
A GOOD CHANCE OF RAIN IN THE MORNING ON MONDAY...TAPERING OFF DURING
THE AFTERNOON HOURS. CLOUD COVER WILL HOLD TEMPS IN THE LOWER 80S.
BY MONDAY NIGHT...A NEW STORM SYSTEM IS TAKING SHAPE OVER THE PLAINS
STATES...AND THE TENNESSEE VALLEY WILL BE BETWEEN THAT SYSTEM AND A
SFC HIGH WEDGING DOWN THE SPINE OF THE APPALACHIANS. NAM IS PROBABLY
OVERDOING THE AMOUNT OF DRYING...SO WILL LEAN MORE TOWARD THE GFS
AND RETAIN A 30 POP AS WELL. GFS IS THEN OVERDONE WITH PRECIP ON
TUESDAY GIVEN ITS 75F SFC DEWPOINTS...SO WILL LEAN BACK TO THE NAM
WITH SCATTERED SHOWERS AND THUNDERSTORMS.
EXTENDED (TUESDAY NIGHT THROUGH NEXT WEEKEND)...
WITH A STRONG UPPER LOW OVER THE PLAINS...AND RIDGING OVER THE
SOUTHEAST...SHRA/TSRA ACTIVITY WILL NOT COME TO AN END...BUT SHOULD
DECREASE IN COVERAGE. NIGHTS WILL GENERALLY BE DRY THROUGH FRIDAY
NIGHT...ALTHOUGH THE PATTERN WILL REMAIN SUCH THAT AN ISOLATED TSTM
CANNOT BE RULED OUT ANYTIME. THE RAIN CHANCE DURING THE DAY WILL BE
DEPENDENT ON THE ULTIMATE LOCATION OF THE RIDGE AND ORIENTATION OF
THE RIDGE AXIS. FOR NOW...WILL PRESUME THAT THE AREA WILL GRADUALLY
GET FURTHER INTO THE RIDGE...AND THUS SHOW POPS TAPERING TO ONLY
SLIGHT CHANCE BY FRIDAY. I ALMOST LEFT THURSDAY NIGHT AND FRIDAY
DRY...BUT SOMETHING TELLS ME IF I DID THAT THOSE WOULD END UP BEING
THE WETTEST DAYS. TEMPERATURES WILL REMAIN ABOVE NORMAL THROUGH THE
END OF THE WORK WEEK.
FOR THE WEEKEND...UNCERTAINTY ABOUNDS...ALTHOUGH MODEL AGREEMENT
BETWEEN THE OPERATIONAL GFS AND ECMWF IS NOT ALL THAT BAD. APPEARS
THAT WHEN THE PLAINS UPPER LOW EJECTS...IT SENDS A COLD FRONT TOWARD
THE AREA. THE QUESTION IS HOW QUICKLY DOES IT PASS THROUGH...AND
GIVEN WHAT WE HAVE BEEN SEEING IN THE MODELS LATELY...I WILL LEAN
TOWARD THE SLOWER TIMING. IF THE MODELS ARE RIGHT...HOWEVER...THIS
COLD FRONT WOULD FINALLY BE THE REAL DEAL...ENDING THE PERSISTENT
WET WEATHER FOR A WHILE...AND BRINGING FALL FINALLY INTO THE AREA.
LETS HOPE.
FAST FACT...
AT HUNTSVILLE...THIS IS ALREADY THE WETTEST SEPTEMBER SINCE 2003.
YEAR-TO-DATE...THE CURRENT TOTAL OF 46.56 INCHES IS THE 17TH WETTEST
AT THIS POINT IN THE YEAR...AND THE WETTEST SINCE 2001. THE STATS
FOR THE OFFICIAL CLIMATE SITE AT MUSCLE SHOALS ARE NOT AS
IMPRESSIVE...BUT SOME VERY HEAVY RAIN HAS OCCURRED NOT FAR FROM
THERE. IN FACT...A GOOD PORTION OF OUR AREA HAS SEEN OVER 50 INCHES
OF RAIN SO FAR THIS YEAR...ESPECIALLY IN LAWRENCE...MORGAN...AND
CULLMAN COUNTIES.
