NATIONAL WEATHER SERVICE BURLINGTON VT
623 PM EDT FRI JUN 10 2005

.SHORT TERM (REST OF TONIGHT)...
SENT MINOR UPDATE TO ADD TIMING TO PRECIPITATION ACROSS THE
FORECAST AREA TONIGHT. CONCENTRATED AREA OF SHOWERS AND
THUNDERSTORMS ACROSS THE ESSEX COUNTY NEW YORK AND POINTS EAST
INTO ADDISON...RUTLAND...AND WINDSOR COUNTIES WILL CONTINUE IN THE
WESTERLY FLOW ALOFT.  WILL MENTION LIKELY CHANCES IN THESE AREAS.
CAPPING LAYER APPEARS TO BE IN PLACE ACROSS THE NORTHERN TIER OF
THE FORECAST AREA...WHERE NO PRECIPITATION IS OCCURRING.
CONVECTION IN SOUTHERN ONTARIO AND SOUTHERN QUEBEC WILL EVENTUALLY
MOVE SOUTHEAST AS FLOW ALOFT BECOMES MORE NORTHWEST WITH TIME.
CONVERGENCE IS FORECAST TO INTENSIFY OVER THE CAPPED REGION AND
WOULD EXPECT CONVECTION TO INCREASE IN AREAL COVERAGE AFTER
SUNSET.  ANY STORMS WILL CONTINUE TO HAVE THE POTENTIAL TO PRODUCE
TORRENTIAL RAINS AND GUSTY WINDS.  WILL LEAVE ENHANCED WORDING IN
THE FORECAST AS WELL AS KEEPING THE FLOOD WATCH INTACT.
TEMPERATURE AND WIND FORECASTS IN REAL GOOD SHAPE ALONG WITH LATER
