.SHORT TERM /SATURDAY THROUGH SUNDAY/...
HIGH PRESSURE WILL MOVE TO OUR SOUTH ON SATURDAY. MOISTURE
CIRCULATING INTO THE AREA BEHIND THE HIGH AND AHEAD OF A WEAK
TROUGH OF LOW PRESSURE APPROACHING FROM THE WEST WILL BRING
INCREASING CLOUDS. SOME SHOWERS WILL BE POSSIBLE SATURDAY
AFTERNOON, MAINLY ACROSS THE NORTH. SATURDAY NIGHT WILL REMAIN
CLOUDY AND A BIT MORE HUMID ACROSS THE AREA. FORECAST GUIDANCE HAS
BEEN CONSISTENT IN SHOWING AN AREA OF SHOWERS TRACKING ACROSS THE
NORTH ON SUNDAY. SYNOPTIC FEATURES ARE VERY WEAK INCLUDING A WEAK
UPPER LEVEL TROUGH AND A VERY WEAK SURFACE FRONT AND WAVE OF LOW
PRESSURE. RAINFALL ON SUNDAY SEEMS TO BE MOSTLY ASSOCIATED WITH
TROPICAL MOISTURE CIRCULATING ACROSS THE REGION IN COMBINATION
WITH SURFACE FRONTAL CONVERGENCE. RAINFALL AMOUNTS BETWEEN A
QUARTER AND A HALF INCH ACROSS THE NORTH APPEAR MOST LIKELY AT
THIS TIME.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
SHOWERS MAY SHIFT SOUTH SUNDAY AFTERNOON AS THE FRONT PUSHES DOWN
TO THE COAST. THE WEAK WAVE OF LOW PRESSURE WILL SLIDE TO OUR
EAST MONDAY AS THE FRONT PUSHES OFFSHORE. HOWEVER, SOME MOISTURE
LINGERING ACROSS THE STATE WILL RESULT IN VARIABLE CLOUDINESS AND
A CONTINUED CHANCE FOR SOME SCATTERED SHOWERS. WEAK RIDGING
COMBINED WITH A SOUTH WINDS AHEAD OF A NEW TROUGH OF LOW PRESSURE
MOVING THROUGH CENTRAL CANADA WILL BRING PARTIAL SUNSHINE ON
TUESDAY. SOME SCATTERED SHOWERS WILL BE POSSIBLE IN WESTERN AREAS
LATE IN THE DAY AHEAD OF AN APPROACHING SURFACE TROUGH OF LOW
PRESSURE. THE TROUGH WILL MOVE THROUGH TUESDAY NIGHT WITH A CHANCE
FOR SHOWERS FOLLOWED BY PARTIAL CLEARING ON WEDNESDAY. A TROUGH OF
LOW PRESSURE WILL BE WELL TO OUR NORTH ON THURSDAY. DRY AIR
