AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
345 PM CDT FRI MAY 18 2012

.DISCUSSION...
THERE HAS BEEN VERY LITTLE CHANGE IN THE SYNOPTIC PATTERN IN PLACE
ACROSS THE TENNESSEE VALLEY SINCE THIS TIME YESTERDAY...WITH AN
ELONGATED MID/UPPER-LEVEL LOW EXTENDING FROM CENTRAL GEORGIA
NORTHEASTWARD OFF THE COAST OF THE MID-ATLANTIC STATES AND A SMALL
BUT STRENGTHENING MID-TROPOSPHERIC RIDGE LOCATED BETWEEN THE SOUTHERN
GREAT LAKES AND THE OHIO RIVER. A WEAK 500-MB SHEAR AXIS REMAINS IN
PLACE ACROSS MUCH OF TENNESSEE AS WELL AS NORTHERN PORTIONS OF
GEORGIA/ALABAMA/MISSISSIPPI...AND THIS WILL CONTINUE TO PROVIDE AN
ENVIRONMENT CONDUCIVE FOR THE DEVELOPMENT OF ISOLATED TO WIDELY
SCATTERED AFTERNOON CONVECTION. AN EAST TO SOUTHEASTERLY STEERING
FLOW ON THE NORTHWESTERN FLANK OF THE SOUTHEASTERN U.S. UPPER CYCLONE
WILL PERSIST FOR THE REMAINDER OF THE AFTERNOON...AND FOR THIS REASON
HAVE MAINTAINED A SLIGHT CHANCE OF SHOWERS/STORMS INTO THE FIRST FEW
HOURS OF THE EVENING PERIOD FOR THE WESTERN HALF OF THE FORECAST
AREA. WEAK LOWER-MID TROPOSPHERIC WINDS /GENERALLY AOB 15 KNOTS/ WILL
LEAD TO LITTLE THREAT FOR ORGANIZED SEVERE CONVECTION ALTHOUGH STRONG
SURFACE HEATING AND VERY STEEP LOW-LEVEL LAPSE RATES WILL PROMOTE A
SMALL HAIL AND GUSTY WIND THREAT WITH THE STRONGEST CELLS.

SIMILAR CONDITIONS TO WHAT HAVE BEEN EXPERIENCED RECENTLY ARE
EXPECTED TO PERSIST FOR THE REMAINDER OF THE SHORT TERM FORECAST
PERIOD. MODELS CONTINUE TO SUGGEST THAT THE MID-LEVEL HIGH TO THE
NORTH OF THE OHIO RIVER WILL STRENGTHEN AND EXPAND NORTHEASTWARD
ACROSS NEW ENGLAND FROM TONIGHT THROUGH TOMORROW NIGHT...IN ADVANCE
OF A STRONG MID-LEVEL VORT MAX LIFTING NORTHEASTWARD ACROSS THE
CENTRAL PLAINS. MEANWHILE...THE SOUTHEASTERN CONUS MID/UPPER-LEVEL
LOW IS FORECAST TO SPLIT INTO TWO SEPARATE VORTICES -- THE STRONGEST
OF WHICH WILL REMAIN SITUATED OFF THE COAST OF THE OUTER BANKS OF
NORTH CAROLINA WHILE THE WEAKER LOW REMAINS NEARLY STATIONARY ACROSS
COASTAL GEORGIA/SOUTH CAROLINA. ALTHOUGH THE INITIAL SHEAR AXIS
CURRENTLY IN PLACE OVER THE REGION MAY TEND TO SHIFT SOUTHWESTWARD
DURING THIS PERIOD...THE POTENTIAL EXISTS FOR ADDITIONAL WAVES TO
PASS OVERHEAD IN THE NORTHEAST FLOW ALOFT...AND WILL MAINTAIN SLIGHT
CHANCES FOR AFTERNOON AND EARLY EVENING SHOWERS/STORMS BOTH TOMORROW
AND ON SUNDAY. FORECAST SOUNDINGS INDICATE THAT STEERING FLOW WILL
ONCE AGAIN BE FROM THE EAST-SOUTHEAST TOMORROW...BUT SHOULD BACK TO
THE NORTH BY SUNDAY AS THE STRENGTHENING MID-LEVEL HIGH OVER NEW
ENGLAND FORCES THE CAROLINAS UPPER LOW TO RETROGRADE INLAND. BY
SUNDAY NIGHT...SHORTWAVE RIDGING ALOFT BUILDING ACROSS THE LOWER
MISSISSIPPI VALLEY IN ADVANCE OF A MORE PRONOUNCED LONG WAVE TROUGH
OVER CENTRAL CANADA MAY ALLOW A LOOSELY-ORGANIZED COMPLEX OF
THUNDERSTORMS TO APPROACH THE AREA IN NORTHWEST FLOW ALOFT. HAVE
INCREASED POPS INTO THE LOW CHANCE RANGE FOR THE NORTHWEST HALF OF
THE FORECAST AREA EARLY MONDAY MORNING TO ACCOUNT FOR THIS
POSSIBILITY. IN TERMS OF THE TEMPERATURE FORECAST...VERY LITTLE
CHANGE IS EXPECTED OVER THE NEXT SEVERAL DAYS...WITH HIGHS REACHING
THE MID 80S-90 DEGREE RANGE EACH AFTERNOON AND LOWS GENERALLY FALLING
INTO THE UPPER 50S/LOWER 60S -- WITH THE EXCEPTION OF VALLEY AREAS IN
THE NORTHEAST WHERE READINGS MAY REACH THE MID 50S. PATCHY FOG WILL
ALSO REMAIN A POSSIBILITY EACH NIGHT...BUT THIS SHOULD PRIMARILY BE
CONFINED TO VALLEYS AND LOCATIONS NEAR BODIES OF WATER.

RAIN CHANCES STILL APPEAR TO BE HIGHEST AT THE BEGINNING OF THE
EXTENDED FORECAST PERIOD...AS THE REMNANTS OF THE PREVIOUSLY
MENTIONED SUNDAY NIGHT MCS MAY LINGER IN THE REGION FOR MUCH OF THE
DAY ON MONDAY. OTHERWISE...EXPECT CHANCES FOR SHOWERS AND STORMS TO
REMAIN FAIRLY HIGH FROM MONDAY NIGHT INTO TUESDAY AS THE SOUTHERN END
OF THE CENTRAL CANADIAN LONG WAVE TROUGH SHIFTS EASTWARD OVER THE
TENNESSEE VALLEY. THIS SYSTEM WILL LIKELY LIFT EAST-NORTHEASTWARD
ACROSS EASTERN KENTUCKY/TENNESSEE...ACROSS THE SOUTHERN APPALACHIANS
AND INTO THE MID-ATLANTIC REGION THROUGH THE MIDDLE AND LATTER
PORTIONS OF NEXT WEEK...WITH MEDIUM RANGE GUIDANCE FROM THE GFS/ECMWF
INDICATING THAT A STRONG MID-LEVEL ANTICYCLONE WILL BUILD ACROSS THE
REGION DURING THIS PERIOD. THUS...ASIDE FROM A FEW AFTERNOON SHOWERS
AND STORMS IN THE HIGHER TERRAIN OF NORTHEAST ALABAMA AND SOUTHERN
MIDDLE TENNESSEE...EXPECT DRY AND VERY WARM CONDITIONS TO PREVAIL
WITH HIGHS REACHING THE LOWER 90S FOR THE MAJORITY OF THE FORECAST
AREA.

.AVIATION...
/ISSUED 1225 PM CDT FRI MAY 18 2012/
FOR 18Z TAFS...PREDOMINATELY VFR CONDITIONS ARE EXPECTED THIS TAF
PERIOD. ISOLATED SHOWERS OR TS ARE POSSIBLE THIS AFTERNOON...AND
JUST PAST THE END OF THE TAF PERIOD TOMORROW. HOWEVER WILL NOT
INCLUDE THESE IN THE TAFS ATTM DUE TO LOW CONFIDENCE. PATCHY FOG IS
AGAIN A POSSIBILITY LATE TONIGHT...AND HAVE NOTED THIS IN TAFS.
