.PREVIOUS DISCUSSIONS
/ISSUED 1044 AM EDT SAT SEP 23 2006/
SHORT TERM /TODAY/
LARGE AREA OF SHOWERS ALONG AND S OF OHRIVER WILL WEAKEN THIS
MORNING BUT STILL REMAIN ACTIVE AS 40-50KT H8 JET MIXES AND
DIMINISHES SLIGHTLY TOWARDS 18Z TODAY AND THEN INCREASES AGAIN OVER
SERN 1/2 OF FCST AREA BY 0Z. UPPER LEVEL DIVERGENCE SPLITS OVER CWA
THIS AFTERNOON AND BECOMES MORE ACTIVE OVERNIGHT ON SE SIDE OF
EXITING JET STREAM. H8 TEMPS ARE FAIRLY STAGNANT AROUND +15 TODAY
UNTIL COLDER PUSH ENTERS FROM THE NW BTWN 0 AND 6Z. LIGHTNING
ACTIVITY IS NOT NOTED IN CWA...IT APPEARS THAT ANY STRONG CONVECTION
WILL HOLD OFF UNTIL SFC LOW AND DYNAMICS SQUEEZE TOGETHER THIS
AFTERNOON OVER ILL/IN. CENTER OF THE UPPER SUPPORT OF H5 LOW REMAINS
NW OF SFC LOW IN IA/WI. MAIN FORCING MECHANISMS THIS PM ARE LOCATED
WELL W AND NW OF CWA. INSTABILITY LOOKS TO BE ON THE INCREASE IN THE
LATE DAY TO THE E AND SE WHERE SOME SUN THROUGH THIN BKN CLOUD DECK
MAY ALLOW CAPES TO APPROACH 1000J/KG. THOUGH IT APPEARS THAT THE
REGION IS SPLIT WITH THE INSTABILITY TO THE SE AND DYNAMICS TO THE
NW...STRONG WINDS OVER THE REGION WILL LIKELY MIX DOWN IN ANY DECENT
CONVECTIVE ACITIVITY THAT GETS GOING.
ATTM...WARMING CLOUD TOPS AND LACK OF ANY THUNDER IN CWA WILL HAVE
ME UPDATE FCST TO LOWER THUNDER CHANCES BUT CONTINUE RAIN. FFG OF
1/2 OVER SRN CWA...PERSISTENT LIGHT TO MODERATE RAINFALL...OCCNL
TRAINING ECHOS...AND THREAT FOR HEAVIER RAINFALL WITH PWAT OF 1.6+
WILL HAVE ME CONTINUE FFWATCH TODAY OVER THE SOUTH.
FRANKS
/ISSUED 444 AM EDT SAT SEP 23 2006/
SHORT TERM /TODAY THROUGH MONDAY/
SHOWERS AND THUNDERSTORMS THAT DEVELOPED IN THE EVENING CONTINUE
TO OCCUR ACROSS THE FAR SOUTHERN ZONES. THIS HAS SATURATED THE
GROUND AND WITH FURTHER PRECIPITATION EXPECTED TODAY HAVE OPTED
TO ISSUE A FLASH FLOOD WATCH FOR THE SOUTHERN HALF. EXPECT CURRENT
ACTIVITY TO LIFT BACK NORTH DURING THE DAY AND ANY PERIOD OF
SUSTAINED MODERATE TO HEAVY RAIN WILL LIKELY LEAD TO FLOODING.
DEPENDING ON WHAT TRANSPIRES TODAY AND WHAT LATER GUIDANCE SHOWS
THIS WATCH MAY NEED TO BE EXTENDED INTO TONIGHT.
THERE IS SOME QUESTION ABOUT HOW MUCH INSTABILITY WILL DEVELOP
THIS AFTERNOON AND EVENING. DEW POINTS ARE ALREADY IN THE MID 60S
AND MAY PUSH A BIT HIGHER. BUT EXTENSIVE CLOUD COVER ALONG WITH
PRECIPITATION MAY LIMIT HEATING. IF THE ATMOSPHERE CAN DESTABILIZE
SUFFICIENTLY THEN SEVERE STORMS WILL BE POSSIBLE AS THERE WILL BE
QUITE A BIT OF SHEAR IN PLACE.
GFS AND NAM CONTINUE TO SHOW DIFFERENCES WITH THE SPEED OF THE
FRONT THROUGH THE AREA TONIGHT. CONSENSUS SEEMS TO CONTINUE TO
FAVOR THE GFS AND THUS HAVE LEANED TOWARDS ITS SOLUTION. SOME
SHOWER AND THUNDERSTORM ACTIVITY SHOULD STILL BE ONGOING IN
EASTERN ZONES ON SUNDAY MORNING BEFORE PUSHING OFF TO THE EAST.
THEN WITH HEATING EXPECT TO GET SOME INSTABILITY SHOWERS AREAWIDE
DURING THE AFTERNOON AND POSSIBLY INTO SUNDAY EVENING. HIGH
PRESSURE BUILDING IN WILL BRING A RETURN OF DRY WEATHER BY MONDAY.
/ISSUED 348 PM EDT FRI SEP 22 2006/
LONG TERM /MONDAY THROUGH FRIDAY/
EXTENDED FCST STARTING MON HAS HIGH PRESSURE BUILDING OVER OHVLY
FROM THE MIDWEST AS LOW PRESSURE RETREATS FROM GTLKS REGION. EXPECT
A GRADUAL WARMING OF THE AIRMASS THROUGH MIDWEEK AS A SFC LOW TRACKS
INTO THE GTLKS WED. THIS WILL SEE A TRAILING COLD FRONT MOVE THROUGH
OHVLY ON WED NITE AND THURS IN RESPONSE TO A STRONG AND PERSISTENTLY
DEEPENING H5 TROF OVER THE ERN 1/2 OF CONUS. MILD AIR WILL SURGE
AHEAD OF THE CDFNT...AND THE STRENGTHENING H5 L/W TROF WILL ALLOW
FOR A STRONG PUSH OF COOL CONTINENTAL AIR INTO THE OHVLY ON NRLY
FLOW AS STRONG SFC HIGH IN THE MIDWEST SETS UP.
STRENGTH OF SYSTEM WED NITE AND THURS HAS ME INCREASE POPS AS THE
FLOW AHEAD OF IT AND SIGNIFICANT HEIGHT FALLS BEHIND IT WOULD LIKELY
SEE A LINE OF CONVECTION MOVE THROUGH THE REGION. COLD POOL SHOWERS
POSSIBLE FOR REMAINDER OF THURS AND INTO FRI...BUT ONLY HAVE 20%
POSSIBILITY HERE BEING THE LAST DAY OF FCST.
TEMPS WERE GENERALLY BUMPED UP AHEAD OF WED NITE FRONT AND DROPPED
BEHIND IT...NOT TOO FAR FROM MEX GUID.
