AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MORRISTOWN TN
330 AM EDT SUN JUL 7 2013
.SHORT TERM...(TODAY AND TONIGHT)...UPPER TROUGH WILL MOVE SLOWLY
EAST ACROSS THE OHIO VALLEY TODAY WITH THE UPPER FLOW BECOMING
WESTERLY BY THIS EVENING PULLING ABNORMALLY HIGH PWS SOUTH AND EAST
OF THE SOUTHERN APPALACHIANS. ALSO...ASSOCIATED UPPER JET WILL PULL
EAST AS WELL WITH DIVERGENCE ALOFT AND FRONTO-GENETIC FORCING
MOVING EAST OF THE AREA THIS AFTERNOON.
BANDS OF LIGHT TO MODERATE RAINS OVER THE AREA WILL CONTINUE MOST
OF THE DAY WITH ISOLATED AFTERNOON STORMS. DUE TO SATURATED
GROUND...ANY ADDITIONAL RAINFALL MAY CAUSE PROBLEMS SO WILL
CONTINUE FLOOD WATCH. AS UPPER TROUGH MOVES NORTHEAST OF THE AREA
THIS EVENING...COVERAGE OF SHOWERS WILL DIMINISH...SO WILL ALLOW
WATCH TO EXPIRE.
.LONG TERM /MONDAY THROUGH SATURDAY/...
WITH THE UPPER-LEVEL TROUGH FINALLY EXITING THE REGION INTO THE
UPPER OHIO VALLEY ON MONDAY AN UPPER-LEVEL RIDGE WILL BUILD IN FOR
THE FIRST HALF OF THE WEEK. HOWEVER...GIVEN THE ABUNDANT GULF
MOISTURE PRESENT UNDERNEATH THIS RIDGE...DECENT CHANCES FOR
SCATTERED DIURNAL CONVECTION WILL EXIST EACH DAY...THOUGH MORE
SUNSHINE AND SLIGHTLY WARMER TEMPERATURES ARE ALSO EXPECTED. THE
NEXT UPPER-LEVEL STORM SYSTEM WILL DROP A COLD FRONT SOUTH FROM THE
OHIO VALLEY INTO THE SOUTHERN APPALACHIANS WEDNESDAY NIGHT INTO
THURSDAY...PROVIDING AN EVEN BETTER CHANCE FOR ORGANIZED SHOWERS AND
THUNDERSTORMS. THUS...HAVE GONE LIKELY POPS AREAWIDE DURING THIS
TIME PERIOD. AS HAS BEEN THE CASE THE PAST SEVERAL DAYS...THE
PRIMARY IMPACTS FROM THESE STORMS WILL CONTINUE TO BE LOCALLY HEAVY
RAINFALL GIVEN THE HIGH MOISTURE CONTENT/PWAT VALUES PROGGED TO BE
IN PLACE. MODELS ARE NOW HINTING AT ANOTHER CUT-OFF LOW DRIFTING
SOUTH LATE THIS WEEK INTO THE WEEKEND...WHICH COULD RESULT IN
ADDITIONAL RAIN CHANCES AND COOLER TEMPERATURES NEXT WEEKEND. GIVEN
THIS...HAVE UNDERCUT MOS GUIDANCE BY A FEW DEGREES AT THE END OF THE
PERIOD.
