A WEAK SHORTWAVE WILL PASS OVERHEAD THIS AFTERNOON, KICKING OFF
WIDELY SCATTERED SHOWERS AND EVEN AN ISOLATED THUNDERSTORM OR
TWO. AREAS MOST LIKELY TO SEE A STORM OR TWO WILL BE IN
NORTHEASTERN PENNSYLVANIA AND AREAS SOUTH AND EAST OF I-81 IN
NEW YORK. THERE WILL BE SOME ELEVATED INSTABILITY PRESENT SO
THUNDERSTORMS WILL BE POSSIBLE, BUT SHEAR IS WEAK SO STRONG
STORMS ARE NOT EXPECTED.
A COLD FRONT WILL DROP SOUTH OUT OF CANADA ON TOMORROW, WITH SCATTERED
SHOWERS AND STORMS ARE FORECAST DEVELOP ACROSS IN THE LATE
MORNING THROUGH EARLY EVENING. THERE WILL BE SOME DRY AIR IN
PLACE AHEAD OF THE FRONT, SO THERE IS A CHANCE THAT SHOWERS WILL
HAVE A HARD TIME DEVELOPING IN THE LATE MORNING/EARLY
AFTERNOON. ONCE MORE MOISTURE MOVES IN FROM THE WEST WITH THE
WITH THE SHORTWAVE TROUGH AXIS, SHOWERS AND ISOLATED STORMS
SHOULD START TO DEVELOP. THE SET UP DOES NOT FAVOR SEVERE
WEATHER AT THIS TIME AS CAPE IS UNDER 1000 J/KG AND 0-6KM BULK
SHEAR IS BELOW 20KTS. A FEW STRONGER PULSE STORMS MAY BE
POSSIBLE IF WE CAN GET SOME POCKETS OF ELEVATED CAPE. PWATS ARE
LOOKING TO BE AROUND 1.5 TO 1.75 INCHES, SO THERE IS POTENTIAL
FOR SOME LOCALIZED HEAVIER RAINFALL, BUT GIVEN HOW DRY IT HAS
BEEN, HYDRO ISSUES ARE NOT EXPECTED.
HIGH PRESSURE MOVES IN FROM THE NORTH BEHIND THE FRONT TO START
THE WORK WEEK AND MUCH COOLER AIR FILLS IN WITH THE NNW FLOW.
TEMPS WILL BE IN THE MID TO UPPER 70S MONDAY, FALLING TO THE LOW
70S BY WEDNESDAY. A SHORTWAVE MOVING INTO THE AREA FROM THE
GREAT LAKES TUESDAY WILL BRING SCATTERED SHOWERS AND STORMS TO
THE AREA THROUGH WEDNESDAY.
LATE IN THE WEEK, HURRICANE ERIN WILL CONTINUE ITS TREK NORTH
THROUGH THE ATLANTIC. IT IS CURRENTLY FORECAST TO REMAIN AT SEA
AS IT GETS PICKED UP BY A DEEPENING TROUGH OVER SE CANADA AS IT
MOVES WELL OFF SHORE OF THE MID- ATLANTIC US.
