.DISCUSSION...
/ISSUED 238 AM CDT FRI AUG 28 2015/

AN UNSEASONABLY COOL AND DRY AIR MASS WILL ABATE LATER TONIGHT AS
THE SOUTHERN FLANK OF AN EXITING TROUGH OFF THE EAST COAST BECOMES
CUTOFF FROM THE PREVAILING WESTERLIES. CURRENTLY THIS UPPER LOW IS
LOCATED OVER THE NORTH CENTRAL GULF COAST. OVER THE COURSE OF TODAY
AND TONIGHT, IT WILL GRADUALLY BEGIN TO AFFECT THE PREVAILING LOW TO
MID LEVEL FLOW ACTING TO SLOWLY SATURATE THE MID LEVELS. THOUGH
SATURATION WILL NOT OCCUR RAPIDLY ENOUGH TO RESULT IN STORM
DEVELOPMENT, LOW LEVEL CLOUD COVER ADVECTING FROM THE EAST SHOULD
DEVELOP THIS AFTERNOON. AN ADDITIONAL IMPACT WILL BE THE WIND
DIRECTION SHIFT TO EASTERLY TO SOUTHEASTERLY FOR LOW-MID LEVELS.
THIS CHANGE IN WIND DIRECTION WILL ACT TO INCREASE MOISTURE
ADVECTION FROM BOTH THE GULF OF MEXICO AND ATLANTIC. SO THAT BY
SATURDAY, SATURATION IS ANTICIPATED THROUGH MUCH OF THE VERTICAL
COLUMN, WHICH COMBINED WITH THE APPROACHING CUTOFF LOW WILL INCREASE
CHANCES FOR PRECIPITATION. A LOOK AT FORECAST SOUNDINGS AND PLAN
VIEW REPRESENTATION OF INSTABILITY SHOW STEEP LOW TO MID LEVEL LAPSE
RATES WITH LOW TO MODERATE CONDITIONAL INSTABILITY ON SATURDAY AND
AGAIN ON SUNDAY. AS A RESULT, THUNDERSTORM DEVELOPMENT IS FORECAST,
BUT WITHOUT APPRECIABLE WIND SHEAR, ANY THUNDERSTORMS THAT DO OCCUR
TO BE PULSE-LIKE IN NATURE. DUE TO THE MODEL RUN CONSISTENCY, WILL
RAISE POPS, ESPECIALLY FOR THE AFTERNOONS ON BOTH SATURDAY AND
SUNDAY. ON THE TEMPERATURE FRONT, WITH THE TN VALLEY BACK IN A
MARITIME TROPICAL ENVIRONMENT ON BOTH DAYS, EXPECTING DAYTIME HIGH
TEMPERATURES TO RISE CLOSE TO 90 WITH A HIGHER PROBABILITY FOR
BREAKS IN THE CLOUDS OVER THE WESTERN HALF OF THE CWA TO CONTRIBUTE
TO THESE HIGHS.

THEN, BY SUNDAY, THE CUTOFF LOW APPEARS TO BEGIN SHIFTING NORTHEAST
TOWARDS THE EASTERN APPALACHIANS (MERGING WITH AN APPROACHING
SHORTWAVE TROUGH) RESULTING IN A DECREASE IN SHOWER/STORM ACTIVITY.
BECAUSE OF ITS PROGGED EXIT, HAVE TAPERED POPS TO MAINLY NE AL/S
MIDDLE TN ON MONDAY. A SHEARED TROUGH THEN FORMS ON THE SOUTHERN
FLANK OF THE APPROACHING SHORTWAVE TROUGH OVER MI/IL/IN. THIS
PORTION OF THE SHORTWAVE TROUGH MAY ACT AS A FOCUS FOR THUNDERSTORM
ACTIVITY BY WEDNESDAY, BUT DUE TO THE UNCERTAINTY WITH THIS AND THE
TRACK OF TC ERIKA, IF IT SURVIVES, WILL KEEP LOW POPS MAINLY FOR
WEDNESDAY. THERE IS PRETTY LOW CONFIDENCE IN THE FORECAST DUE TO THE
INTERACTIONS WITH THIS SHEARED TROUGH AND POSSIBLE DIRECT/INDIRECT
IMPACTS FROM TC ERIKA. FURTHERMORE, WILL KEEP TEMPERATURES NEAR OR
JUST BELOW AVERAGE (30 YEAR) FOR THIS TIME OF YEAR ON MONDAY AND
TUESDAY (DAYTIME HIGHS NEAR 90S AND OVERNIGHT LOWS IN UPPER 60S).
HOWEVER, WITH THE INCREASE IN SFC DEWPOINTS (I.E. RETURN OF SUMMER
LIKE HUMIDITY), EXPECT IT TO FEEL WARMER WITH HEAT INDEX VALUES
RETURNING TO THE LOW TO MID 90S BY MID WEEK.

238 AM CDT FRI AUG 28 2015

.DISCUSSION...

AN UNSEASONABLY COOL AND DRY AIR MASS WILL ABATE LATER TONIGHT AS
THE SOUTHERN FLANK OF AN EXITING TROUGH OFF THE EAST COAST BECOMES
CUTOFF FROM THE PREVAILING WESTERLIES. CURRENTLY THIS UPPER LOW IS
LOCATED OVER THE NORTH CENTRAL GULF COAST. OVER THE COURSE OF TODAY
AND TONIGHT, IT WILL GRADUALLY BEGIN TO AFFECT THE PREVAILING LOW TO
MID LEVEL FLOW ACTING TO SLOWLY SATURATE THE MID LEVELS. THOUGH
SATURATION WILL NOT OCCUR RAPIDLY ENOUGH TO RESULT IN STORM
DEVELOPMENT, LOW LEVEL CLOUD COVER ADVECTING FROM THE EAST SHOULD
DEVELOP THIS AFTERNOON. AN ADDITIONAL IMPACT WILL BE THE WIND
DIRECTION SHIFT TO EASTERLY TO SOUTHEASTERLY FOR LOW-MID LEVELS.
THIS CHANGE IN WIND DIRECTION WILL ACT TO INCREASE MOISTURE
ADVECTION FROM BOTH THE GULF OF MEXICO AND ATLANTIC. SO THAT BY
SATURDAY, SATURATION IS ANTICIPATED THROUGH MUCH OF THE VERTICAL
COLUMN, WHICH COMBINED WITH THE APPROACHING CUTOFF LOW WILL INCREASE
CHANCES FOR PRECIPITATION. A LOOK AT FORECAST SOUNDINGS AND PLAN
VIEW REPRESENTATION OF INSTABILITY SHOW STEEP LOW TO MID LEVEL LAPSE
RATES WITH LOW TO MODERATE CONDITIONAL INSTABILITY ON SATURDAY AND
AGAIN ON SUNDAY. AS A RESULT, THUNDERSTORM DEVELOPMENT IS FORECAST,
BUT WITHOUT APPRECIABLE WIND SHEAR, ANY THUNDERSTORMS THAT DO OCCUR
TO BE PULSE-LIKE IN NATURE. DUE TO THE MODEL RUN CONSISTENCY, WILL
RAISE POPS, ESPECIALLY FOR THE AFTERNOONS ON BOTH SATURDAY AND
SUNDAY. ON THE TEMPERATURE FRONT, WITH THE TN VALLEY BACK IN A
MARITIME TROPICAL ENVIRONMENT ON BOTH DAYS, EXPECTING DAYTIME HIGH
TEMPERATURES TO RISE CLOSE TO 90 WITH A HIGHER PROBABILITY FOR
BREAKS IN THE CLOUDS OVER THE WESTERN HALF OF THE CWA TO CONTRIBUTE
TO THESE HIGHS.

THEN, BY SUNDAY, THE CUTOFF LOW APPEARS TO BEGIN SHIFTING NORTHEAST
TOWARDS THE EASTERN APPALACHIANS (MERGING WITH AN APPROACHING
SHORTWAVE TROUGH) RESULTING IN A DECREASE IN SHOWER/STORM ACTIVITY.
BECAUSE OF ITS PROGGED EXIT, HAVE TAPERED POPS TO MAINLY NE AL/S
MIDDLE TN ON MONDAY. A SHEARED TROUGH THEN FORMS ON THE SOUTHERN
FLANK OF THE APPROACHING SHORTWAVE TROUGH OVER MI/IL/IN. THIS
PORTION OF THE SHORTWAVE TROUGH MAY ACT AS A FOCUS FOR THUNDERSTORM
ACTIVITY BY WEDNESDAY, BUT DUE TO THE UNCERTAINTY WITH THIS AND THE
TRACK OF TC ERIKA, IF IT SURVIVES, WILL KEEP LOW POPS MAINLY FOR
WEDNESDAY. THERE IS PRETTY LOW CONFIDENCE IN THE FORECAST DUE TO THE
INTERACTIONS WITH THIS SHEARED TROUGH AND POSSIBLE DIRECT/INDIRECT
IMPACTS FROM TC ERIKA. FURTHERMORE, WILL KEEP TEMPERATURES NEAR OR
JUST BELOW AVERAGE (30 YEAR) FOR THIS TIME OF YEAR ON MONDAY AND
TUESDAY (DAYTIME HIGHS NEAR 90S AND OVERNIGHT LOWS IN UPPER 60S).
HOWEVER, WITH THE INCREASE IN SFC DEWPOINTS (I.E. RETURN OF SUMMER
LIKE HUMIDITY), EXPECT IT TO FEEL WARMER WITH HEAT INDEX VALUES
RETURNING TO THE LOW TO MID 90S BY MID WEEK.

OF INTENSIFICATION. ITS EVENTUAL PATH BY THE EARLY/MID PART OF NEXT

THE NEXT COUPLE DAYS OVER THE SOUTHERN BAHAMAS.

ONE LAST DRY DAY SHOULD BE REALIZED FOR FRIDAY...BEFORE RAIN CHANCES

HIGH SHOULD MOVE OFF OF THE MID ATLANTIC/NEW ENGLAND COAST BY
SATURDAY...PLACING THE FORECAST AREA IN A SE SURFACE FLOW. THIS OF

DRY AND MILD TEMPERATURES ARE IN STORE TODAY UNDERNEATH THE
INFLUENCE OF LARGE SCALE NORTHWESTERLY FLOW AND A SFC HIGH PRESSURE
SYSTEM CENTERED OVER THE APPALACHIANS AND OH RIVER VALLEY,
RESPECTIVELY. DAYTIME HIGH TEMPERATURES SHOULD REGISTER IN THE LOW TO
MID 80S WHILE DEWPOINTS CONTINUE TO BE UNSEASONABLY COOL, IN THE 50S.
FORECAST SOUNDINGS AND PLAN VIEW DISPLAYS OF DEWPOINT DEPRESSIONS
ALOFT DO SHOW SATURATION AT 5-7KFT THIS AFTERNOON WHICH ALONG WITH
RISING AIR PARCELS MAY RESULT IN A CU FIELD DEVELOPING. THUS, MADE
SLIGHT ADJUSTMENTS TO THE SKY COVER FORECAST TO INDICATE THAT FOR
TODAY. MEANWHILE, MEAN RIDGING OVER THE WESTERN HALF OF THE CONUS
WILL GRADUALLY DAMPEN AS A MID-LEVEL SHORTWAVE TROUGH ROTATING AROUND
THE NORTHERN FLANK OF THE RIDGE MOVES ACROSS THE INTERMOUNTAIN WEST.
FURTHER EAST, THE TROUGH AXIS THAT HAD BEEN PREVAILING ACROSS THE
EASTERN HALF OF THE CONUS WILL BE MOVING NE TOWARDS EASTERN
QUEBEC/GREENLAND ON THU/FRI.

DUE TO THE EASTWARD MOVEMENT OF THE TROUGH, THE PREVAILING SFC HIGH
PRESSURE SYSTEM CENTER THAT HAS BEEN KEEPING COOL AND DRY CONDITIONS
ACROSS THE TN VALLEY WILL MOVE EAST TOWARDS THE CENTRAL
APPALACHIANS. THAT IN TURN WILL MEAN SOUTHERLY SFC FLOW WILL RETURN
TO THE SOUTHEAST, AND A SUBSEQUENT SLOW RISE IN DEWPOINT. THEN, THE
PREVIOUSLY MENTIONED SHORTWAVE TROUGH BECOMES SHEARED APART WHILE
THE SOUTHERN FLANK OF THE EXITING LONGWAVE TROUGH OVER THE NE
BECOMES CUTOFF OVER THE N GULF COAST. THE SUBSEQUENT CUTOFF LOW
APPEARS TO MERGE WITH A PIECE OF SHEARED SHORTWAVE TROUGH AND
GRADUALLY MOVE ONSHORE AND ACROSS GA/AL BY FRIDAY NIGHT INTO
SATURDAY/SUNDAY. AS THIS CUTOFF LOW MEANDERS NORTHEAST ACROSS
CENTRAL AL/GA, MODEL OUTPUT SUGGESTS THAT ISOLATED TO SCATTERED
AFTERNOON THUNDERSTORMS WILL BE POSSIBLE ESPECIALLY OVER NE AL ON
SATURDAY/SUNDAY. THIS OCCURS AS ENVIRONMENTAL LAPSE RATES STEEPEN
AND SUBSEQUENT WEAK INSTABILITY CONTRIBUTES TO DEEP CONVECTIVE
UPDRAFTS. STORMS ON SATURDAY MAY BE MORE DIURNALLY DRIVEN GIVEN THE
WEAK FLOW AND HODOGRAPH SIGNATURE. DAYTIME HIGHS WILL BE WARMER ON
SATURDAY DUE TO THE SOUTHERLY FLOW.

BY EARLY NEXT WEEK, THE PREVAILING UPPER FLOW WILL TRANSITION TO
RIDGING OVER MUCH OF THE COUNTRY WHILE AN ADDITIONAL CUTOFF LOW
FORMS FROM REMNANT VORTICITY ON SUNDAY INTO MONDAY. THIS CUTOFF LOW
ALONG WITH NORTH ATLANTIC RIDGE WILL BE THE PRIMARY STEERING
MECHANISMS FOR TC ERIKA. THE LATEST MODEL TRENDS POINT MORE TOWARDS
AN INDIRECT EFFECT ACROSS THE TN VALLEY WITH TC ERIKA AS IT MAY
DIRECTLY IMPACT THE CAROLINAS. THE MAIN EFFECT WOULD BE DRY AIR
ADVECTION HERE, IF THIS SOLUTION VERIFIES, BUT WITH THE CUTOFF LOW
SET TO MEANDER CLOSER TO THE TN VALLEY, ISOLATED TO SCATTERED
THUNDERSTORMS WOULD BE POSSIBLE. GIVEN THE COMPLEX AND MORE MESOSCALE
VAGARIES OF A CUTOFF LOW, EXPECT THAT THE TRACK OF ERIKA AND EFFECTS
FROM THE CUTOFF LOW WILL LIKELY CHANGE SEVERAL TIMES OVER THE COMING
DAYS. SO, HAVE LEFT LOWER END CHANCE OF THUNDERSTORMS IN THE FORECAST
FOR NOW.

FORECAST SOUNDINGS AND PLAN VIEW DISPLAYS OF DEWPOINT DEPRESSIONS
ALOFT DO SHOW SATURATION AT 5-7KFT THIS AFTERNOON WHICH ALONG WITH
RISING AIR PARCELS MAY RESULT IN A CU FIELD DEVELOPING. THUS, MADE
SLIGHT ADJUSTMENTS TO THE SKY COVER FORECAST TO INDICATE THAT FOR
TODAY. MEANWHILE, MEAN RIDGING OVER THE WESTERN HALF OF THE CONUS
WILL GRADUALLY DAMPEN AS A MID-LEVEL SHORTWAVE TROUGH ROTATING AROUND
THE NORTHERN FLANK OF THE RIDGE MOVES ACROSS THE INTERMOUNTAIN WEST.
FURTHER EAST, THE TROUGH AXIS THAT HAD BEEN PREVAILING ACROSS THE
EASTERN HALF OF THE CONUS WILL BE MOVING NE TOWARDS EASTERN
QUEBEC/GREENLAND ON THU/FRI.

DUE TO THE EASTWARD MOVEMENT OF THE TROUGH, THE PREVAILING SFC HIGH
PRESSURE SYSTEM CENTER THAT HAS BEEN KEEPING COOL AND DRY CONDITIONS
ACROSS THE TN VALLEY WILL MOVE EAST TOWARDS THE CENTRAL
APPALACHIANS. THAT IN TURN WILL MEAN SOUTHERLY SFC FLOW WILL RETURN
TO THE SOUTHEAST, AND A SUBSEQUENT SLOW RISE IN DEWPOINT. THEN, THE
PREVIOUSLY MENTIONED SHORTWAVE TROUGH BECOMES SHEARED APART WHILE
THE SOUTHERN FLANK OF THE EXITING LONGWAVE TROUGH OVER THE NE
BECOMES CUTOFF OVER THE N GULF COAST. THE SUBSEQUENT CUTOFF LOW
APPEARS TO MERGE WITH A PIECE OF SHEARED SHORTWAVE TROUGH AND
GRADUALLY MOVE ONSHORE AND ACROSS GA/AL BY FRIDAY NIGHT INTO
SATURDAY/SUNDAY. AS THIS CUTOFF LOW MEANDERS NORTHEAST ACROSS
CENTRAL AL/GA, MODEL OUTPUT SUGGESTS THAT ISOLATED TO SCATTERED
AFTERNOON THUNDERSTORMS WILL BE POSSIBLE ESPECIALLY OVER NE AL ON
SATURDAY/SUNDAY. THIS OCCURS AS ENVIRONMENTAL LAPSE RATES STEEPEN
AND SUBSEQUENT WEAK INSTABILITY CONTRIBUTES TO DEEP CONVECTIVE
UPDRAFTS. STORMS ON SATURDAY MAY BE MORE DIURNALLY DRIVEN GIVEN THE
WEAK FLOW AND HODOGRAPH SIGNATURE. DAYTIME HIGHS WILL BE WARMER ON
SATURDAY DUE TO THE SOUTHERLY FLOW.

BY EARLY NEXT WEEK, THE PREVAILING UPPER FLOW WILL TRANSITION TO
RIDGING OVER MUCH OF THE COUNTRY WHILE AN ADDITIONAL CUTOFF LOW
FORMS FROM REMNANT VORTICITY ON SUNDAY INTO MONDAY. THIS CUTOFF LOW
ALONG WITH NORTH ATLANTIC RIDGE WILL BE THE PRIMARY STEERING
MECHANISMS FOR TC ERIKA. THE LATEST MODEL TRENDS POINT MORE TOWARDS
AN INDIRECT EFFECT ACROSS THE TN VALLEY WITH TC ERIKA AS IT MAY
DIRECTLY IMPACT THE CAROLINAS. THE MAIN EFFECT WOULD BE DRY AIR
ADVECTION HERE, IF THIS SOLUTION VERIFIES, BUT WITH THE CUTOFF LOW
SET TO MEANDER CLOSER TO THE TN VALLEY, ISOLATED TO SCATTERED
THUNDERSTORMS WOULD BE POSSIBLE. GIVEN THE COMPLEX AND MORE MESOSCALE
VAGARIES OF A CUTOFF LOW, EXPECT THAT THE TRACK OF ERIKA AND EFFECTS

MORE BEAUTIFUL WEATHER ACROSS THE TENNESSEE VALLEY THIS AFTERNOON...
COURTESY OF HIGH PRESSURE CENTERED ACROSS THE CENTRAL PLAINS. A
NORTHERLY FLOW AROUND THE HIGH CONTINUED A TREND OF DRY AND COOLER
THAN NORMAL CONDITIONS FOR MUCH OF THE CENTRAL AND EASTERN CONUS.
AFTER OVERNIGHT LOWS IN THE IN THE 50S...HIGHS SO FAR HAVE REBOUNDED
NICELY...INTO THE UPPER 70S TO MID 80S WITH 5-10 MPH NORTHERLY WINDS.

A NW FLOW PREVAILED ALOFT...AS THE NORTHERN STREAM FLOWED NORTH OF
THE UPPER RIDGE ACROSS THE SOUTHERN ROCKIES. THIS FLOW GOING INTO
TROUGHING ALONG THE EAST COAST WAS KEEPING CLOUDS...AND SHOWER
ACTIVITY WELL TO OUR EAST. FURTHER TO THE SE...TS ERICKA WAS CHURNING
OVER THE ATLANTIC AROUND 220 MILES EAST OF ANTIGUA. IT COULD PLAY A
ROLE IN OUR SENSIBLE WEATHER SOMETIME NEXT WEEK.

FOR THE SHORTER TERM OR AT LEAST FOR THE REST OF THE WORK WEEK...
DRY CONDITIONS WILL CONTINUE. ANOTHER COOL NIGHT IS IN THE FORECAST
TONIGHT AS LOWS FALL INTO THE MID/UPPER 50S. OLD RECORD LOWS AT
MUSCLE SHOALS AND HUNTSVILLE...BOTH 53 SHOULD STAND. TOMORROW SHOULD
BE A REPEAT PERFORMANCE WITH HIGHS AGAIN IN THE LOW/MID 80S. DAYTIME
HEATING AND A TAD BIT MORE MOISTURE SHOULD RESULT IN A FEW FAIR
WEATHER CUMULUS IN THE LATE MORNING AND AFTERNOON. SIMILAR WEATHER IS
FORECAST ON FRIDAY...WITH MAYBE A FEW MORE CLOUDS...ESPECIALLY OVER
OUR EASTERN AREAS.

SOMEWHAT DEEPER MOISTURE ADVECTING IN FROM THE EAST...ALONG WITH
STRONG DAYTIME HEATING AND RESULTING INSTABILITY WILL BRING RAIN
CHANCES BACK TO THE TENNESSEE VALLEY ON SATURDAY. RAIN CHANCES
SHOULD STAY NEAR AND EAST OF I-65. HAVE A SLIGHT CHANCE OF SHOWERS/
STORMS FOR THE ENTIRE AREA TO START A NEW WEEK.

AFTERWARD...THE FORECAST COULD HINGE ON THE EVENTUAL TRACK OF TC
ERICKA. THIS TROPICAL SYSTEM PER NHC FORECASTS HAS IT NEARING THE SE
FLORIDA COAST AROUND EARLY MON MORNING. MODEL OUTPUT FROM THE
GFS/ECMWF WERE NOT TO DISSIMILAR THIS GO AROUND THAT FAR OUT. THE
ECMWF THIS TIME TURNED THE SYSTEM TO THE NORTH...JUST EAST OF THE
FLORIDA COAST... WHILE THE GFS BRINGS IT ASHORE. GIVEN
UNCERTAINLY...HAVE MAINTAINED SLIGHT SHOWER CHANCES MON-TUE...AND
RAISED THEM TO LOWER END CHANCE RANGE NEXT WED. IF CLOUD COVERAGE
DOES NOT BECOME TOO EXTENSIVE...TEMPERATURES SHOULD CREEP UP INTO
THE MID/UPPER 80S...CLOSE TO SEASONABLE VALUES FOR THAT TIME OF YEAR.

SOME VALLEY LOCATIONS IN NORTHEAST ALABAMA AND SOUTHERN MIDDLE
TENNESSEE. THUS FAR, NO VALLEY FOG WAS BEING OBSERVED.

WATER VAPOR IMAGERY DEPICTED NWLY FLOW ACROSS THE MIDWEST INTO THE
SOUTHEAST U.S. AS HAS BEEN FORECAST THE PAST FEW DAYS, A TROF AXIS IS
FORECAST TO DEVELOP THIS WEEK ACROSS THE APPALACHIANS INTO THE
CENTRAL GULF OF MEXICO. OUR FORECAST AREA WILL REMAIN ON THE NW SIDE
OF THIS AXIS, WITH SINKING AIR PERSISTING. EVENTUALLY, AN UPPER LOW
WILL BREAKOFF FROM THE TROF OVER THE CENTRAL GULF BY FRIDAY INTO
SATURDAY. BY THAT TIME, LOW-MID LEVEL FLOW WILL BECOME SRLY-SELY
WHICH WILL INCREASE COLUMNAR MOISTURE. HOWEVER, FORCING WILL REMAIN
NEGLIGBLE THROUGH FRIDAY, WITH CONVECTION BECOMING POSSIBLE ALONG
THE HIGHER TERRAIN OF THE SMOKIES INTO NWRN GA AND POSSIBLY FAR NERN
AL ON SATURDAY, AND FURTHER WEST ON SUNDAY.

NO FURTHER SIG CHANGES WERE MADE TO BLENDS WHICH MATCHES THE PREVIOUS
FORECAST FAIRLY WELL. THERE IS A HIGH AMOUNT OF UNCERTAINTY THAT

HIGH PRESSURE HAS NOW EXTENDED ALONG THE MS RIVER VALLEY FROM
MINNESOTA SOUTH TO THE GULF COAST. LOCALLY, CALM OR LIGHT NORTHERLY
FLOW WAS IN PLACE. TEMPS AS OF 06Z HAD DIPPED INTO 54-55 DEGREES AT
SOME VALLEY LOCATIONS IN NORTHEAST ALABAMA AND SOUTHERN MIDDLE
TENNESSEE. THUS FAR, NO VALLEY FOG WAS BEING OBSERVED.

WATER VAPOR IMAGERY DEPICTED NWLY FLOW ACROSS THE MIDWEST INTO THE
SOUTHEAST U.S. AS HAS BEEN FORECAST THE PAST FEW DAYS, A TROF AXIS IS
FORECAST TO DEVELOP THIS WEEK ACROSS THE APPALACHIANS INTO THE
CENTRAL GULF OF MEXICO. OUR FORECAST AREA WILL REMAIN ON THE NW SIDE
OF THIS AXIS, WITH SINKING AIR PERSISTING. EVENTUALLY, AN UPPER LOW
WILL BREAKOFF FROM THE TROF OVER THE CENTRAL GULF BY FRIDAY INTO
SATURDAY. BY THAT TIME, LOW-MID LEVEL FLOW WILL BECOME SRLY-SELY
WHICH WILL INCREASE COLUMNAR MOISTURE. HOWEVER, FORCING WILL REMAIN
NEGLIGBLE THROUGH FRIDAY, WITH CONVECTION BECOMING POSSIBLE ALONG
THE HIGHER TERRAIN OF THE SMOKIES INTO NWRN GA AND POSSIBLY FAR NERN
AL ON SATURDAY, AND FURTHER WEST ON SUNDAY.

NO FURTHER SIG CHANGES WERE MADE TO BLENDS WHICH MATCHES THE PREVIOUS
FORECAST FAIRLY WELL. THERE IS A HIGH AMOUNT OF UNCERTAINTY THAT
CONTINUES WRT THE EVENTUAL TRACK OF T.S. ERIKA. THE 12Z ECMWF HAS A
TRACK THAT COULD INFLUENCE OUR WEATHER TO A CERTAIN EXTENT JUST

NWLY FLOW IN MID TO UPPER LEVELS WILL BRING A WEAK AND DRY SHORTWAVE
