.SHORT TERM /SUNDAY THROUGH MONDAY/...
A STRONG RIDGE OF HIGH PRESSURE WILL BE ANCHORED IN THE NORTHEAST
OVER THE WEEKEND ALLOWING WARM AND HUMID MID SUMMER LIKE WEATHER.
SUNDAY WILL BE SUNNY WITH JUST A FEW PATCHY CLOUDS POSSIBLE OVER THE
FAR NORTH. THIS WILL GIVE WAY TO A MOSTLY CLEAR AND UNSEASONABLY
WARM NIGHT SUNDAY NIGHT. MONDAY WILL CONTINUE TO BE VERY WARM BUT
WILL BE BREEZY AS THE GRADIENT BETWEEN SURFACE HIGH PRESSURE PUSHING
TO THE SOUTH AND A TROUGH OF LOW PRESSURE TO THE NORTH CREATES A
WEST SOUTHWESTERLY BREEZE. A WEAK SHORTWAVE WILL BRING A CHANCE FOR
SOME SPOTTY SHOWERS OR THUNDERSTORMS MONDAY AFTERNOON WITH THE BEST
CHANCE FOR SHOWERS IN WESTERN OR CENTRAL AREAS.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
WE WILL BE ON THE NORTHERN EDGE OF THE WARM RIDGE OF HIGH PRESSURE
MONDAY NIGHT INTO TUESDAY. MOISTURE OVER THE NORTHERN EDGE OF THIS
RIDGE WILL BRING A MOSTLY CLOUDY DAY TUESDAY WITH A CONTINUED CHANCE
FOR SOME SHOWERS. THE AIR WILL REMAIN VERY WARM AND HUMID. BY
WEDNESDAY, LOW PRESSURE OVER CENTRAL CANADA WILL BE PULLING AN
OCCLUDED FRONT ACROSS OUR AREA BRINGING A BETTER CHANCE FOR SHOWERS.
DRIER AND SLIGHTLY COOLER WEATHER SHOULD FOLLOW FOR THURSDAY. OUR
ATTENTION LATE IN THE WEAK THEN FOCUSES ON A STORM SYSTEM
POSSIBLY APPROACHING FROM THE SOUTHWEST LATER FRIDAY INTO SATURDAY
TO BRING A CHANCE FOR RAIN.

&&

.AVIATION /12Z SATURDAY THROUGH WEDNESDAY/...
NEAR TERM: VFR EXPECTED NEXT 24 HOURS. CONFIDENCE IS LOW ON ANY
PATCHY FOG DEVELOPING AT ANY ONE TERMINAL GIVEN DRY LOW LEVEL
AIRMASS. HOWEVER...LOCALLY VARIABLE CONDITIONS COULD OCCUR WITH
ANY PATCHY FOG THROUGH SUNRISE.

SHORT TERM: PATCHY FOG MAY RESULT IN LOCALLY IFR CONDITIONS AT SOME
SITES SUNDAY MORNING. OTHERWISE, VFR CONDITIONS ARE EXPECTED
SUNDAY AND MONDAY. CONDITIONS MAY LOWER TO MVFR MONDAY NIGHT INTO
WEDNESDAY AS A FRONTAL BOUNDARY BRINGS LOWER CLOUDS AND THE CHANCE
FOR SHOWERS OVER THE AREA.

ADVISORY CRITERIA THROUGH THE WEEKEND.
