THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHERN NEW YORK AND VERMONT.

.DAY ONE...TODAY:

THE POTENTIAL WILL EXIST LATER TODAY AND THIS EVENING ACROSS VERMONT
AND THE CHAMPLAIN VALLEY FOR SOME THUNDERSTORMS TO CONTAIN GUSTY
WINDS AND HEAVY RAINFALL.  THIS WILL BE THE RESULT OF AN UPPER LEVEL
TROUGH OF LOW PRESSURE MOVING ACROSS EASTERN CANADA AND AN
INCREASINGLY UNSTABLE AIR MASS OVER THE REGION.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY:

WEAK HIGH PRESSURE WILL BUILD INTO THE REGION ON FRIDAY AND PROVIDE
THE REGION WITH PLENTY OF SUNSHINE AND A CONTINUATION OF ABOVE NORMAL
TEMPERATURES.  DEEP MOISTURE TO MOVE TOWARD THE REGION THIS WEEKEND
AND INCREASE THE CHANCES FOR AFTERNOON AND EVENING SHOWERS AND
THUNDERSTORMS FROM SATURDAY THROUGH THE MIDDLE PART OF NEXT WEEK.
SINCE THIS DEEPER MOISTURE WILL BE FROM WHAT WAS ONCE HURRICANE
DENNIS...THE STORMS WILL HAVE THE POTENTIAL TO PRODUCE HEAVY
RAINFALL.

.SPOTTER CALL TO ACTION STATEMENT...

SPOTTER ACTIVATION MAY BE REQUIRED LATER TODAY AND THIS EVENING
ACROSS VERMONT AND THE ENTIRE CHAMPLAIN VALLEY.
