.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...

AS OF 255 PM EDT FRIDAY...

WEATHER PATTERN STARTS TO GET ACTIVE AGAIN SUNDAY WITH HIGH PRESSURE
SETTING UP OFF THE SOUTHEAST COAST AND DEEP SW TO WEST FLOW
INCREASING THE HEAT AND HUMIDITY AGAIN. SUNDAY WILL BE A DAY ON
WHICH MTN CONVECTION FORMS IN THE AFTERNOON BUT ORGANIZED ACTIVITY
IS NOT EXPECTED. GOING INTO SUNDAY NIGHT AND MONDAY SHORTWAVE ENERGY
CROSSES THE OHIO VALLEY INTO THE MID ATLANTIC WITH A SFC TROUGH
MOVING INTO THE LEE OF THE APPALACHIANS. MODELS ARE IN AGREEMENT
THAT SHOULD SEE MORE CONVECTION BUT PLACEMENT VARIES. MAJORITY SHOWS
BETTER THREAT ARRIVING INTO THE WRN CWA AFTER MIDDAY MONDAY WITH
LIKELY POPS ADDED. KEPT HIGH CHANCE IN THE EAST. AT THE MOMENT SPC
AND MODELS INDICATING LOWER THREAT OF SVR WITH DYNAMICS LACKING AS
STRONG WIND FIELDS STAY NORTH ACROSS THE GREAT LAKES. STILL LOOKS
UNSTABLE ENOUGH THAT ISOLATED SVR COULD OCCUR.

SUNDAY WILL BE THE WARMEST DAY THINKING MORE CLOUDS AND PRECIP WILL
KEEP MONDAY A FEW DEGREES COOLER. HIGHS SUNDAY WILL RANGE FROM NEAR
90 SOUTHEAST TO UPPER 70S TO LOWER 80S IN THE WEST. MONDAY WILL HAVE
HIGHS IN THE MID 80S EAST AND MID TO UPPER 70S WEST.

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
-- Changed Discussion --
AS OF 1225 PM EDT FRIDAY...

A COLD FRONT IS EXPECTED TO BE MOVING ACROSS THE AREA TUESDAY. AT
THIS TIME...MODELS ARE NOT AS STRONG WITH THIS SYSTEM COMPARED
YESTERDAYS. STILL DEFINITELY A THREAT FOR SHOWERS AND
THUNDERSTORMS...SOME OF WHICH COULD BE STRONG. TIMING SUGGESTS MOST
ACTIVITY TO OCCUR LATE MONDAY NIGHT/EARLY TUESDAY.

FRONT EXPECTED TO SLOW DOWN AS IT MOVES SOUTH OF THE AREA MIDWEEK.
AT THIS TIME...OVERALL PATTERN SUGGESTS DRY WITH HIGH PRESSURE
PARKING ITSELF IN THE MID ATLANTIC. SFC WINDS TURN FROM NORTH TO
EAST/SOUTHEAST THU-FRI NEXT WEEK SO THAT IMPULSE MOVING ACROSS THE
AREA COMBINED WITH DEEPER MOISTURE NEARBY TO THE SOUTH COULD BRING A
FEW SHOWERS OR THUNDERSTORMS ACROSS OUR SRN TIER OF COUNTIES. KEPT
POPS LOW FOR NOW GIVEN SFC PATTERN.

CONDITIONS WARM/MUGGY MON NIGHT-TUESDAY START TO COOL A LITTLE
BEHIND THE FRONT FRONT TUE NIGHT-THU. TEMPS STILL STAY SEASONAL INTO
FRIDAY GIVEN THE FLOW WILL BE OUT OF THE EAST...SOUTHEAST AND
LIGHT...BUT HUMIDITY LEVELS START TO CLIMB SOME AGAIN.
