.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM THURSDAY/...
-- Changed Discussion --
RIDGE REMAINS ACROSS THE REGION TONIGHT INTO THURSDAY AS SURFACE
HIGH REMAINS TO THE NORTHEAST AND RIDGES DOWN ALONG THE EASTERN
SLOPES OF THE APPALACHIANS. THE COLD AIR MASS WILL REMAIN IN PLACE
TONIGHT INTO THURSDAY. TEMPERATURES WILL AGAIN APPROACH OF FALL
BELOW FREEZING ACROSS THE AREA. NO RECORDS ARE EXPECTED TO BE

AIR LATER TONIGHT INTO THURSDAY. THURSDAYS HIGHS WILL ONLY BE A
COUPLE OF DEGREES HIGHER THAN TODAYS HIGHS.
-- End Changed Discussion --

&&

.LONG TERM /THURSDAY NIGHT THROUGH TUESDAY/...
-- Changed Discussion --
INITIALLY DRY WEATHER THURSDAY NIGHT AS THE CENTER OF THE SURFACE
HIGH PUSHES NORTH AND EAST WHILE THE AREA REMAINS UNDER BROAD
RIDGING. GLOBAL MODELS SUGGEST WEAK LOW PRESSURE DEVELOPMENT ALONG A
STALLED FRONT OFFSHORE THAT COULD BRING LIGHT PCPN INTO THE AREA BY
FRIDAY MORNING...THEN SLOWLY SPREADING TO THE NORTH FRI NIGHT INTO
SAT. 00Z GFS A BIT MORE PRONOUNCED IN THE DEVELOPMENT OF THE LOW AND
THE RESULTING PCPN WITH THE SUGGESTION OF INTERACTION BETWEEN A
SOUTHERN STREAM SHORTWAVE WITH THE NORTHERN STREAM TROUGH/CLOSED
LOW. ALL OTHER MODELS KEEP A DISTINCT SEPARATION BETWEEN THE TWO SO
WENT AHEAD AND MAINTAINED THE SLIGHT CHC/CHC POPS FOR NOW WITH
UNCERTAINTY ON JUST HOW WIDESPREAD THE PCPN OCCURS. AN APPROACHING
FRONT SAT COULD TRIGGER SCT RAIN SHOWERS AS THE UPPER LEVEL TROUGH
SWINGS THROUGH. THINGS THEN DRY OUT FOR SAT NIGHT-SUNDAY WITH ZONAL FLOW
SETTING UP ALOFT AND HIGH PRESSURE BUILDING SOUTH INTO THE
NORTHEAST.

SOME MODEL DISCREPANCIES IN THE HANDLING OF THE NEXT LOW PRESSURE
SYSTEM NEXT WEEK. 00Z GFS LINGERS THE HIGH OVER THE NORTHEAST THEN
BRINGS A WEAK FRONT IN FROM THE WEST WHILE ECMWF AND CMC BOTH
DEVELOP A DECENT AREA OF LOW PRESSURE OFF COASTAL FLORIDA AND TRACK
TO THE NORTH ALONG A STALLED FRONT. FLOW ALOFT SUGGESTS MORE OF A
GFS SOLUTION IN THIS CASE...SO SIDED MORE TO A GFS/WPC
BLEND...BRINGING POPS IN MONDAY NIGHT AND KEEPING THEM IN PLACE
THROUGH TUESDAY WITH THE FRONT REMAINING IN THE VICINITY AND
MULTIPLE SHORTWAVES RIDING THE FLOW ALOFT.

COOLER WEATHER IN STORE FOR THE TRI STATE AREA THURS NIGHT/FRI AS
THE POSITIONING OF THE HIGH KEEPS A COOLER EASTERLY/NORTHEASTERLY
FLOW DESPITE WAA ALOFT. HOWEVER...AS WINDS SHIFT FOR THE
WEEKEND...EXPECT TEMPS TO WARM BACK TO NEAR NORMAL. OVERALL...TEMPS
EXPECTED TO REMAIN WARM ENOUGH WITH TIMING OF PCPN TO KEEP PCPN IN
THE FORM OF RAIN. THURS NIGHT WILL BE THE COLDEST NIGHT IN THE
EXTENDED...THOUGH CURRENTLY NOT EXPECTING FROST/FREEZE ISSUES IN
AREAS CURRENTLY IN THE GROWING SEASON.
