AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
343 PM CDT THU JUL 8 2010
.DISCUSSION...
AN UPR RIDGE EXPANDING SLOWLY SWWRD ACROSS THE SE CONUS HAS BROUGHT
VERY WARM TEMPERATURES TO THE REGION ONCE AGAIN TODAY...WITH MOST
LOCATIONS REPORTING VALUES IN THE MID/UPR 90S. DEEP MIXING THOUGH HAS
ALLOWED DEW POINT TEMPS TO FALL INTO THE 60S AT MOST LOCATIONS.
WHILE RESULTING HEAT INDICES HAVE NOT REACHED 105 YET...MANY
LOCATIONS ARE AROUND 100 DEGREES. WHERE DEW POINT TEMPS ARE LOWEST
IN THE EAST...MORE ENERGY INPUT HAS GONE INTO SENSIBLE HEATING.
TEMPS HAVE REACHED 99 DEGREES AT FORT PAYNE AND 98 AT DESOTO STATE
PARK.
A RIBBON OF SCTD SHRA/TS HAVE DEVELOPED ALONG A THETA-E RIDGE
EXTENDING FROM CENTRAL MISS THROUGH NW AL...AND INTO MIDDLE TN.
GIVEN THE MARGINALLY UNSTABLE AND WEAKLY SHEARED
ENVIRONMENT...EXPECT MOST OF THESE SHRA/TS TO REMAIN RELATIVELY
SMALL AND SHORT-LIVED. A FEW COULD PRODUCE BRIEF HEAVY RAINFALL AND
GUSTY WINDS WHERE THEY OCCUR THROUGH THE REMAINDER OF THE AFTN. THIS
ACTIVITY IS EXPECTED TO DECREASE WITH THE LOSS OF HEATING...AND
COULD LAST INTO THE EARLY EVENING. WILL MENTION JUST AN ISOLD
SHRA/TS FOR NWRN AREAS WHICH APPEAR TO BE FAVORED FOR ANY LINGERING
ACTIVITY. PATCHY FOG COULD OCCUR OVERNIGHT ESPECIALLY IN THOSE AREAS
THAT RECEIVE RAINFALL TODAY...MOST LIKELY IN OUR VALLEY LOCATIONS IN
SRN MIDDLE TN. OTHERWISE...QUIET WX CONDITIONS EXPECTED OVERNIGHT.
TEMPS WILL REMAIN QUITE WARM THOUGH...WITH MOST VALUES IN THE
LOW/MID 70S.
AS THE UPR TROUGH CONTINUES TO DIG INTO THE EASTERN CONUS...A SFC
COLD FRONT WILL MOVE SWRD INTO THE TN VALLEY ON FRIDAY. CONVERGENCE
ALONG THE FRONT COMBINED WITH UPR FORCING AND INSTABILITY SHOULD BE
SUFFICIENT TO PRODUCE SCTD TO NUMEROUS SHRA AND TS ESPECIALLY DURING
THE AFTERNOON. THE MOST LIKELY LOCATION FOR INITIAL DEVELOPMENT
FRIDAY WILL BE UPSTREAM ACROSS TN/KY. THIS ACTIVITY WILL MOVE TO THE
SOUTH WITH THE FRONT...AND SHOULD BEGIN TO EXPAND ACROSS OUR FCST
AREA DURING THE AFTN. WILL GO WITH LIKELY POPS IN THE NORTHERN HALF
OF THE AREA TO INDICATE BETTER EXPECTED COVERAGE THERE. THE VERTICAL
THERMODYNAMIC/MOISTURE PROFILE SUGGESTS MAINLY A STRONG WIND GUST
THREAT WITH ANY STRONGER STORMS.
ACTIVITY WILL GRADUALLY DECREASE ALONG THE FRONT AS IT SLIPS SLOWLY
SOUTHWARD ACROSS NRN ALABAMA FRIDAY NIGHT. NEVERTHELESS...WILL KEEP
THE 40 POP TO INDICATE THE POTENTIAL FOR SCTD ACTIVITY...ESPECIALLY
DURING THE EVENING. FORWARD PROGRESS WITH THE FRONT WILL SLOW
SIGNIFICANTLY ON SATURDAY AS THE UPR TROUGH PUSHES OFF TO THE EAST.
GIVEN THE PROXIMITY OF THE FRONT...WILL RETAIN CHANCE POPS FOR
SOUTHERN AREAS AND SLIGHT CHANCE NORTH.
A REPRIEVE FROM SHRA/TS ACTIVITY LOOKS LIKELY ON SUNDAY WITH THE OLD
FRONT FAR ENOUGH TO THE SOUTH AND VIRTUALLY NO UPR SUPPORT. WITH
DECENT INSOLATION AND DEEP MIXING EXPECTED...HIGH TEMPS WILL
PROBABLY CLIMB BACK INTO THE LOW/MID 90S ON SUNDAY.
MODEL CONSENSUS IS FAIRLY HIGH FOR EARLY NEXT WEEK...WHILE
INDICATING THAT A SECONDARY UPR TROUGH AND FRONT WILL PUSH INTO THE
REGION. WILL RETAIN CHANCE POPS FOR NOW...BUT LOOK FOR THESE VALUES
TO INCREASE IN SUBSEQUENT FCSTS IF CURRENT MODEL TRENDS HOLD.
THE TYPICAL DIFFERENCES IN MED RANGE GUIDANCE EXISTS FROM THE MIDDLE
OF NEXT WEEK ONWARDS. HOWEVER...THE LARGE SCALE DEPICTION SUGGESTS A
MORE ZONAL FLOW PATTERN WILL DEVELOP WITH WEAK RIDGING BUILDING BACK
INTO THE SOUTHEAST CONUS BY LATE THIS WEEK. THIS WOULD PORTEND
GENERALLY SMALL CHANCES FOR RAINFALL BY LATE NEXT WEEK WITH
GRADUALLY INCREASING TEMPS.
