OCCASIONALLY HEAVY RAINS OVER NEW ENGLAND... IN ASSOCIATION WITH A
DEPARTING UPPER LOW OVER THE NORTHEAST AND HURRICANE KYLE... WILL
BE LARGELY COMING TO AN END BY TOMORROW MORNING. THE SOLID PATCH
OF RAIN AND THUNDERSTORMS...CURRENTLY OVER NEW YORK AND
PENNSYLVANIA... IS EXPECTED TO TRACK TO THE EAST WHILE DISSIPATING
AS IT IS TIED TO THE MOVEMENT OF THE UPPER LOW WHICH SHOULD WEAKEN
IN TIME. STEADY RAIN OVER EASTERN NEW ENGLAND INTO EASTERN CANADA
WILL MOVE NORTH THIS EVENING AND TONIGHT AS HURRICANE KYLE MOVES
NORTH WHILE BECOMING EXTRATROPICAL. ELSEWHERE AROUND THE MID
ATLANTIC REGION AND NORTHEAST... SCATTERED SHOWERS WITH SHORT
LIVED... LOCALLY HEAVY DOWNPOURS WILL CONTINUE TO DOT THE REGION
BEFORE DIMINISHING TONIGHT. CLEARING SKY CONDITIONS WILL MOVE INTO
THE MID ATLANTIC AND NORTHEAST ON MONDAY INTO TUESDAY AS HIGHER
PRESSURE MOVES IN BEHIND A COLD FRONT WHICH WILL CONNECT INTO THE
REMNANTS OF KYLE AFTER IT FULLY TRANSITIONS INTO AN EXTRATROPICAL
SYSTEM.
THE SOUTHERN HALF OF FLORIDA IS EXPECTED TO REMAIN WET THROUGH
TUESDAY AS A WEAKENING STATIONARY FRONT OVER THE STATE INTERACTS
WITH A SLOW MOVING UPPER LEVEL DISTURBANCE. DEEP TROPICAL MOISTURE
NEAR AND SOUTH OF THE SURFACE BOUNDARY WILL ALLOW FOR COPIOUS
RAINFALL TOTALS OVER THE LOWER HALF OF THE STATE UNDER LOCALLY
HEAVY DOWNPOURS.
OVER THE MIDDLE OF THE COUNTRY... A COLD FRONT WILL BRING MUCH
COOLER AND DRIER AIR INTO THE REGION BY TUESDAY... LOWERING HIGH
TEMPERATURES ROUGHLY 10 TO 20 DEGREES COMPARED TO TODAY FROM THE
CENTRAL PLAINS TO THE MIDWEST AND UPPER MISSISSIPPI VALLEY. AHEAD
OF THE FRONT... STRONG TO SEVERE STORMS ARE POSSIBLE OVER NEBRASKA
THIS EVENING INTO THE OVERNIGHT HOURS... MOVING INTO IOWA AND
NORTHERN MISSOURI BY MONDAY MORNING. SHOWERS AND STORMS WILL
CONTINUE OUT AHEAD OF THE FRONT IMPACTING THE UPPER GREAT LAKES
DOWN TO THE OHIO VALLEY MONDAY EVENING INTO TUESDAY MORNING.
OUT WEST... IT WILL STAY MOSTLY DRY EXCEPT FOR SCATTERED AFTERNOON
AND EVENING CONVECTION OVER PORTIONS OF THE INTERMOUNTAIN WEST FOR
THE NEXT FEW DAYS. AS UPPER LEVEL RIDGING DOMINATES INTO THE FIRST
HALF OF THIS WEEK... EXPECT HIGH TEMPERATURES TO RUN ABOUT 10
DEGREES ABOVE AVERAGE UNDER MOSTLY SUNNY SKIES.
