ANOTHER NICE DRY WARM DAY. MOST AREAS GOT TO AROUND 80 DEGREES.
THIS WAS STILL WELL SHY OF THE RECORD BUT THE WARMEST SINCE LAST
SUMMER. SW WINDS HAVE BEEN INCREASING AHEAD OF THE COLD FRONT IN
SRN ONTARIO. A BAND OF PREFRONTAL SHOWERS AND A FEW TS IS IN WRN
NY SLOWLY MOVING EAST. THIS WILL DIE SOME AS IT MOVES INTO THE
DRIER AIR OVER CWA. MARGINAL INDICES AND MID LEVEL LAPSE RATES
MAY BE ENOUGH TO AID THIS FORCING TO PRODUCE A TS OVER THE NW CWA
LATE THIS AFTN INTO EARLY EVENING. WITH THE DRY LOW LEVEL AIR ANY
SHOWERS WILL DIE AS THEY MOVE EAST. THIS IS HINDERING ANY SFC
LIFT. WITH THE LATE EVENING FROPA DIURNAL HEATING WILL BE ON THE
WANE ALSO CUTTING THE INSTABILITY. BASIN AVERAGES LESS THAN A
TENTH OF AN INCH.
HIGH PRESSURE AND MORE DRY BUT MUCH COOLER AIR WILL MOVE IN LATE
TONIGHT AND LAST INTO EARLY WEDNESDAY.

THE AREA MIDDAY INTO WED NGT. THE MODELS HAVE COME INTO BETTER
AGREEMENT AS TO LOCATION AND AMOUNT OF RAIN. BOTH GFS AND NAM HAVE
THE ENTIRE CWA GETTING SOME RAIN. THE EDGE OF THE RAIN WILL BE
NEAR OUR NRN BORDER WITH THE MOST IN NE PA. TOTAL QPF OF LESS THAN
HALF AN INCH. THIS WILL DO LITTLE TO THE RIVERS WITH THEM FALLING
OVER THE LAST SEVERAL DAYS. POPS TAPER FROM CHC IN FAR NORTH TO
LIKELY SRN HALF.
AS THE WEAK SFC LOW MOVES OUT WED NGT THE TRAILING FRONT WILL SINK
SOUTH TO MID ATLANTIC REGION. SOME DRYING ESPECIALLY IN THE NORTH
BEFORE THE NEXT STRONGER SYSTEM COMES IN LATE THURSDAY AHEAD OF A
UL TROF.
LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
THURSDAY NIGHT THROUGH FRIDAY, SURFACE LOW PRESSURE IS PROGGED TO
MOVE FROM THE TENNESSEE VALLEY NORTHEAST INTO THE OHIO VALLEY THEN
ACROSS NORTHERN PENNSYLVANIA. SYSTEM EXPECTED TO MOVE OFF NEW
ENGLAND COAST BY SATURDAY MORNING. THIS SYSTEM WILL RESULT IN
HIGHEST POPS OVER NE PENNSYLVANIA. AS SYSTEM LIFTS WELL OFF TO THE
NORTHEAST ON SATURDAY, THERE STILL IS THE CHC FOR LINGERING SHOWERS
ESPECIALLY DURING THE MORNING. DUE TO BRIEF SURFACE RIDGING,
SATURDAY NIGHT AND SUNDAY LOOK DRY. A SFC LOW TRACKING ACROSS
SOUTHERN CANADA SUNDAY NIGHT INTO MONDAY WILL DRAG A COLD FRONT OVER
THE REGION AND BRING THE CHC FOR MORE SHOWERS.
