DISCUSSION
KEY MESSAGE 1...TODAY WILL BE COOLER WITH LESS WIND AND HIGHER
HUMIDITY LEVELS COMPARED TO YESTERDAY.
THE HIGH TO OUR NORTH ALONG WITH LOW PRESSURE EAST OF THE
CANADIAN MARITIMES WILL HELP DRIVE A BACKDOOR COLD FRONT
SOUTHWARD THROUGH THE AREA THIS MORNING. THIS WILL ALSO BRING
SOME INCREASING CLOUD COVER. EXPECT PARTLY TO MOSTLY CLOUDY
SKIES WITH LIGHT NE WINDS AND COOLER TEMPERATURES COMPARED TO
YESTERDAY. HIGHS WILL BE MAINLY IN THE 60S TO AROUND 70 EXCEPT
COOLER NEAR THE COAST AND A BIT WARMER OVER OUR EASTERN MD
COUNTIES IN DELMARVA SINCE THIS WILL BE CLOSER TO THE FRONT. THE
COOLER TEMPERATURES WILL RESULT IN HUMIDITY LEVELS BEING HIGHER
THAN TODAY ALONG WITH LIGHTER WINDS SO WE DON'T EXPECT THERE TO
BE FIRE WEATHER CONCERNS.
KEY MESSAGE 2...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 ON SATURDAY AND THEN TURN MORE OUT OF THE NORTHEAST
SUNDAY. THIS ONSHORE FLOW WILL HELP KEEP TEMPERATURES ON THE
CHILLIER SIDE THROUGH THE WEEKEND. HIGHS ON SATURDAY WILL BE IN THE
MID 40S TO UPPER 50S FOR MOST. ON SUNDAY, HIGHS ARE IN THE 50S.
DURING THE WEEKEND, A LOW PRESSURE SYSTEM WILL MOVE INTO THE REGION
SATURDAY AND THEN OFFSHORE SUNDAY. THIS LOW PRESSURE SYSTEM WILL
BRING RAIN SHOWERS TO THE AREA THROUGH THE WEEKEND. THE MOST
WIDESPREAD COVERAGE OF THE RAIN SHOWERS LOOKS TO BE SATURDAY INTO
SATURDAY NIGHT. SHOWERS TAPER OFF THROUGH SUNDAY MORNING WITH
PERHAPS A LINGERING SHOWER INTO SUNDAY AFTERNOON NEAR THE COAST. OUR
WEEKEND IS SHAPING UP TO BE WET, BREEZY, AND CHILLY, ESPECIALLY
SATURDAY. RAINFALL TOTALS THIS WEEKEND, FROM FRIDAY NIGHT THROUGH
SUNDAY, WILL RANGE FROM AROUND 1 TO 1.50 INCHES ACROSS MUCH OF
THE AREA. WHILE THIS MAY BE UNPLEASANT, ESPECIALLY SINCE IT WILL
BE OVER THE WEEKEND, IT IS GOOD TO REMEMBER THAT THIS IS A
BENEFICIAL RAINFALL.
TEMPERATURES THEN START TO MODERATE FOR THE BEGINNING AND MIDDLE OF
NEXT WEEK. OUR NEXT SYSTEM ARRIVES FOR TUESDAY THROUGH THURSDAY
BRINGING MORE RAIN SHOWERS TO THE AREA.
