AREA FORECAST DISCUSSION

1243 PM CDT SUN JUN 26 2011

.UPDATE...FOR 18Z TAFS.

&&

.AVIATION...
A SECOND MCS WAS MOVING SOUTHWARD THROUGH THE SOUTHWEST PART OF
MIDDLE TN AT 1730Z. STILL NO SIGNS OF WARMING ON IR SATL PICS SO
EXPECT THIS MCS TO CONTINUE MOVING SSEWD FOR NEXT COUPLE/FEW
HOURS BEFORE LATER THIS AFTERNOON. THE LEADING LINE OF TSTMS HAS
PASSED KBNA SO JUST SOME SHRA THERE FOR NEXT COUPLE HOURS.

MCS SHOULD REMAIN WEST OF KCSV BUT STILL A CHANCE FOR TSTMS TO
REDEVELOP IN THAT REGION. HOWEVER...AIRMASS MAY BE RAIN COOLED
ENOUGH FROM THE PREVIOUS MCS TO PREVENT TOO MUCH CONVECTION.
CONVECTIVE CLOUDS AT BOTH SITES SHOULD END EARLY THIS EVENING. NW
FLOW STORM THREAT ALWAYS SEEMS TO LINGER FOR AT LEAST ONE MORE DAY
THAN EXPECTED...AND MODELS HINT AT SOME CHANCE FOR ANOTHER ONE
TOMORROW MORNING. MAIN PATH SHOULD BE FURTHER EAST AS H5 RIDGE
BUILDS SO THREAT IS HIGHER AT KCSV THAN AT KBNA.  LV

&&

.PREV DISCUSSION... /ISSUED 1052 AM CDT SUN JUN 26 2011/

UPDATE...
OUTFLOW BOUNDARY FROM EARLY MORNING MCS HAS MOVED SOUTHWARD THRU
ALL OF MIDDLE TN PER VISIBLE SATL AND KHTX 88D AND WAS NEAR A
LINE FROM JACKSON TO SAVANNAH TO HUNTSVILLE AT 15Z. THE OUTFLOW
WAS STILL MOVING SOUTH ALONG ITS ALABAMA PORTION BUT THE WEST TN
PORTION WAS NEARLY STATIONARY.

SECOND MCS DEVELOPED THIS MORNING ON THE WESTERN EDGE OF THE
ORIGINAL MCS. IT MOVED FROM SRN IL THRU SW KY...AND AT 15Z WAS
MOVING INTO NW TN INCLUDING SEVERAL COUNTIES IN NW MIDDLE TN. 15Z
IR SATL PICS DO NOT INDICATE ANY WARMING SO BELIEVE THIS COMPLEX
WILL CONINTUE MOVING SSEWD AND IMPACT THE NW 1/3 TO 1/2 OF MIDDLE
TN WITH SOME VERY HEAVY RAINS BEFORE IT WEAKENS EARLY THIS
AFTERNOON.

STILL A CHANCE FOR NEW STORMS TO DEVELOP MID/LATE THIS AFTERNOON
GENERALLY SOUTH AND EAST OF THE SECOND MCS. HOWEVER...EVEN THOSE
AREAS SHOULD BE SUFFICIENTLY RAIN COOLED TO PREVENT WIDESPREAD
REDEVELOPMENT.

ADJUSTED MOST FIRST PERIOD GRIDS...ESPECIALLY POPS/TEMPS/WX...IN
FORECAST PACKAGE THAT HAS ALREADY BEEN ISSUED.  LV

PREV DISCUSSION... /ISSUED 643 AM CDT SUN JUN 26 2011/

UPDATE...FOR 26/12Z AVIATION FORECAST

AVIATION...
LEADING EDGE OF COMPLEX HAS PUSHED SOUTH OF BNA AIRPORT AND IS JUST
ABOUT TO MOVE INTO CSV. BASICALLY HAVE SHOWERS AND A FEW TSTMS
UNTIL ABOUT 26/16Z AT BNA AND UNTIL ABOUT 26/17Z AT CSV. RAIN
SHIELD EXTENDS ALL THE WAY BACK TO THE OHIO RIVER SO NOT ALOT OF
CONFIDENCE ON TIMING IN THE CESSATION OF SHOWERS/TSTMS AT EITHER
LOCATION. ALSO EXPECT REDEVELOPMENT TO TAKE PLACE IN THE AFTERNOON
AND EVENING.

PREV DISCUSSION... /ISSUED 325 AM CDT SUN JUN 26 2011/

DISCUSSION...
SFC BOUNDARY CONTINUES TO MEANDER AROUND THE MID-SOUTH AND HAS NOW
MOVED JUST NORTH OF THE TN/KY BORDER. NORTHWEST FLOW CONTINUES AT
MLS WHICH CONTINUES TO BRING COMPLEX DOWN INTO KY THIS MORNING.
FRONTAL BOUNDARY WILL CONTINUE TO MOVE SLOWLY NORTH TODAY SETTING
UP ACROSS NORTHERN KY TOWARD 00Z. COMPLEX WILL CONTINUE MOVING
SOUTH THIS MORNING BUT SHORT FUSE MODELS SHOW IT WEAKENING SOME EARLY.
EVEN IF THIS HAPPENS IT WILL LIKELY REFIRE LATER ON OUTFLOWS AS
AIRMASS PLENTIFUL WITH INSTABILITY/ENERGY. HAVE RAISED POPS
ACROSS THE BOARD TODAY. FRONTAL BOUNDARY WILL REMAIN NORTHERN KY
VICINITY TONIGHT BUT TAKE OFF NORTH ON MONDAY AS SFC LOW MOVES
INTO THE GREAT LAKES AND A SECONDARY FORMS DOWN ACROSS TX.
MEANWHILE RIDGE ALOFT WILL STRENGTHEN SOME...LIMITING CONVECTION.
STORMS MAY REMAIN SCT ACROSS THE NORTHEAST MONDAY BUT WILL BE ISO
ELSEWHERE.

COLD FRONT ASSOCIATED WITH GREAT LAKES/PLAINS LOWS GET BIG PUSH
MONDAY NIGHT FROM TRAILING ML/UL TROUGHS...AND EVENTUALLY PUSHES
DOWN INTO THE MID-STATE ON TUESDAY. SHWRS/STORMS WILL BECOME
FAIRLY WIDESPREAD TUESDAY LATE MORNING AS UVV/INSTABILITY BECOMES
ENHANCED AHEAD OF BOUNDARY. FRONT DROPS SOUTH OF THE AREA TUESDAY
NIGHT FROM STRONG SFC/LL GREAT LAKES HIGH AND PASSING UPPER
TROUGHS. GOOD DRYING OCCURS AS THIS HAPPENS AND AIRMASS REMAINS
DRIER INTO LATE FRIDAY AS SFC HIGH/UPPER RIDGES TAKE OVER. NO POPS
PLANNED WEDNESDAY-FRIDAY.

A WEAK BOUNDARY WILL BRING SMALL POPS BACK INTO THE FOLD SATURDAY.

.OHX WATCHES/WARNINGS/ADVISORIES...
