KEY MESSAGE 1...WIDESPREAD RAIN SHOWERS THIS WEEKEND WITH
POSSIBLE THUNDERSTORMS EACH AFTERNOON.
KEY MESSAGE 1 DESCRIPTION...
ANY SHOWERS AND STORMS THAT DEVELOP EARLY THIS EVENING WILL
TAPER OFF OVERNIGHT TONIGHT. ANOTHER ROUND OF SHOWERS AND STORMS
WILL DEVELOP LATE SATURDAY MORNING WITHIN THE WARM SECTOR OF AN
APPROACHING OPEN WAVE LOW PRESSURE. INSTABILITY WILL EXIST,
THOUGH BE ON THE LOWER END WITH ONLY AROUND 100 J/KG CAPE AT
BEST AND STRONG CAPPING INVERSION WITHIN THE MARINE LAYER. THAT
SAID, SOME ELEVATED CONVECTION REMAINS POSSIBLE AND ISOLATED
THUNDERSTORMS ARE MOST LIKELY THROUGH THE MID TO LATE AFTERNOON
ON SATURDAY ACROSS THE CENTRAL HIGHLANDS DOWN THROUGH THE
INTERIOR DOWNEAST REGION.
A COLD FRONT WILL THEN CROSS THE REGION SATURDAY NIGHT INTO
SUNDAY, BRINGING ADDITIONAL MOISTURE TO THE AREA AND MORE
WIDESPREAD WETTING RAIN SHOWERS. TEMPERATURES WILL BE MUCH
COOLER BY THE DAY ON SUNDAY WITH HIGHS ONLY LIFTING INTO THE MID
60S TO LOWER 70S.
KEY MESSAGE 2...STRONG UPPER LEVEL RIDGING MOVES IN MONDAY AND
LASTS AT LEAST INTO THE END OF NEXT WEEK, BRINGING HOT
TEMPERATURES OF 10-15 DEGREES ABOVE AVERAGE.
KEY MESSAGE 2 DESCRIPTION...
AS THE COLD FRONT MOVES OUT OF THE AREA SUNDAY NIGHT INTO
MONDAY, A RIDGE IN THE JET STREAM MOVES IN BEHIND IT. THIS RIDGE
WILL MOVE IN AND PARK OVER THE QUEBEC REGION OF CANADA THROUGH
AT LEAST THE END OF NEXT WEEK. STRONG HIGH PRESSURE FROM THE
RIDGE WILL LIMIT PRECIPITATION AND BRING HOT TEMPERATURES FOR AN
EXTENDED PERIOD OF TIME. TEMPERATURES WILL BE 10-15 DEGREES
ABOVE AVERAGE THROUGH AT LEAST NEXT FRIDAY, REACHING THE UPPER
80S AND POTENTIALLY THE LOW 90S. MODELS ARE IN GOOD AGREEMENT
ABOUT THE HIGH PRESSURE, BUT EXACT POSITION AND STRENGTH ARE A
LITTLE MORE UNCERTAIN WHICH WOULD AFFECT HOW HOT TEMPERATURES
GET.
