DISCUSSION
KEY MESSAGE 1...A LOW PRESSURE SYSTEM WILL PASS THROUGH THE REGION
THIS WEEKEND WITH WIDESPREAD SHOWERS AND SEASONABLY CHILLY
TEMPERATURES.
A HIGH PRESSURE SYSTEM TO THE NORTH IN EASTERN CANADA WILL EXTEND
DOWN INTO THE NORTHEAST THIS WEEKEND. AS A RESULT, WINDS WILL BE OUT
OF THE EAST TODAY AND THEN TURN MORE OUT OF THE NORTHEAST TOMORROW.
THIS ONSHORE FLOW WILL HELP KEEP TEMPERATURES ON THE CHILLIER SIDE
THROUGH THE WEEKEND. HIGHS TODAY WILL BE IN THE MID 40S TO UPPER 50S
FOR MOST. FOR TOMORROW, HIGHS ARE IN THE UPPER 40S TO MID 50S.
A LOW PRESSURE SYSTEM WILL MOVE INTO THE REGION TODAY AND THEN
OFFSHORE TOMORROW. THIS LOW PRESSURE SYSTEM WILL BRING RAIN SHOWERS
TO THE AREA INTO TOMORROW. THE MOST WIDESPREAD COVERAGE OF THE RAIN
SHOWERS LOOKS TO BE THIS AFTERNOON INTO TONIGHT. SHOWERS TAPER OFF
THROUGH TOMORROW MORNING WITH PERHAPS A LINGERING SHOWER INTO
TOMORROW AFTERNOON NEAR THE COAST. OUR WEEKEND IS SHAPING UP TO BE
WET, BREEZY, AND CHILLY, ESPECIALLY TODAY. RAINFALL TOTALS THROUGH
TOMORROW, WILL RANGE FROM AROUND 1 TO 1.50 INCHES ACROSS MUCH OF THE
AREA WITH LOCALIZED HIGHER AMOUNTS. WHILE THIS MAY BE UNPLEASANT,
ESPECIALLY SINCE IT WILL BE OVER THE WEEKEND, IT IS GOOD TO REMEMBER
THAT THIS IS A BENEFICIAL RAINFALL.
WITH COOLER AIR WRAPPING IN FROM THE NORTH TONIGHT, IT IS POSSIBLE
SOME WET SNOW TRIES TO MIX IN WITH THE RAIN FOR THE POCONOS. LITTLE
TO NO ACCUMULATION IS EXPECTED.

DURING THE MIDDLE OF NEXT WEEK.
AFTER A BRIEF PERIOD OF HIGH PRESSURE ON MONDAY, A WEAK FRONTAL

FOR LIGHT RAIN. THIS FRONTAL BOUNDARY WILL LARGELY WASH OUT
ACROSS THE REGION EARLY WEDNESDAY BEFORE ANOTHER STRONGER LOW
ARRIVES LATE WEDNESDAY INTO EARLY THURSDAY THAT COULD BRING MORE
WIDESPREAD SHOWERS AND PERHAPS AN ISOLATED THUNDERSTORM ACROSS
THE REGION. TEMPERATURES WILL REMAIN SEASONABLE WITH AFTERNOON
HIGHS IN THE 60S AND NIGHTTIME LOWS IN THE 40S TO AROUND 50.
