DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
DRIER AIR CONTINUES TO WORK ITS WAY IN OVERNIGHT TONIGHT. THIS
BRINGS DEW POINTS DOWN INTO THE 50S AND LOW 60S, ALLOWING TEMPS
TO FOLLOW AND BRING A MUCH COOLER NIGHT THAN THE LAST SEVERAL.
LOWS BOTTOM OUT IN THE UPPER 50S TO NEAR 60 FOR MOST INTERIOR
LOCATION, WHILE THE COAST HOLDS ONTO SOME LOW TO MID 60S.
A SEASONABLY WARM DAY IS EXPECTED TOMORROW WITH WIDESPREAD
HIGHS IN THE MID 80S. A SEA BREEZE DOES KNOCK TEMPS BACK ALONG
THE COAST BY THE AFTERNOON HOURS. DEW POINTS WILL MAINLY BE IN
THE LOW 60S TOMORROW, KEEPING HEAT INDICES IN STEP WITH THE
ACTUAL AIR TEMPS.
A COLD FRONT APPROACHES DURING THE DAY TOMORROW. A WEAK LOW
DEVELOPS ALONG THIS FRONT AND MOVES THROUGH SOUTHERN QUEBEC LATE
TOMORROW AND TOMORROW NIGHT. THIS LIKELY BRINGS A ROUND OF
SHOWERS AND STORMS IN FROM THE WEST BY LATE TOMORROW, AND MORESO
TOMORROW EVENING. THE MOST WIDESPREAD ACTIVITY FOR THESE WILL
BE ACROSS THE NORTH AND NEAR THE CANADIAN BORDER, WITH CHANCES
DROPPING OFF TOWARD THE COAST. A STRONG STORM CAN'T BE RULED OUT
EARLY IN THE EVENING, BUT OTHERWISE THE MAIN FOCUS WOULD BE FOR
HEAVY RAINFALL ON ANY SPOTS THAT SEE A COUPLE STORMS MOVE OVER
THE SAME AREAS. THIS FRONT THEN MOVES OFFSHORE BY LATE IN THE
NIGHT, WITH CLEARING SKIES FOLLOWING BY DAYBREAK TUESDAY.
KEY MESSAGE 2 DESCRIPTION...
THE WEATHER LOOKS RELATIVELY BENIGN TUESDAY INTO NEXT WEEKEND
WITH COOLER AND DRIER AIRMASSES MOVING IN FROM TIME TO TIME. THE
BEST CHANCE OF SHOWERS AND THUNDERSTORMS LOOKS TO BE LATE

THE 70S IN THE MOUNTAINS TO LOWER 80S TO MID 80S AT LOWER
