.DISCUSSION...

A FEW INTERVALS OF SUNSHINE EARLY IN THE MORNING WILL ALLOW
SURFACE HEATING TO OCCUR WHICH WILL IN TURN LEAD TO AN INCREASE
IN CLOUD COVER BY AFTERNOON.

TEMPERATURES WILL BEGIN TO MODERATE DURING THE REST OF THE WEEK
AS HIGH PRESSURE MOVES OVER THE REGION. THIS HIGH WILL THEN SHIFT
TOWARD THE EAST COAST FRIDAY. THE NEXT LOW PRESSURE SYSTEM WILL
ORGANIZE OVER CENTRAL CANADA THROUGH THE CENTRAL PLAINS STATES
DURING THE WEEKEND. THIS SYSTEM WILL HELP SOUTHERLY WINDS DEVELOP
AND BRING INCREASING MOISTURE TO OUR AREA WITH SHOWERS AND
THUNDERSTORMS LIKELY THROUGH MOST OF THE WEEKEND.
