AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE GRAY ME
241 AM EDT WED AUG 11 2004

.SHORT TERM (TODAY THROUGH TONIGHT)...
LOW PRES IN ONTARIO WILL CLOSE OFF AS IT MOVES N TODAY AND TONIGHT.
THE FIRST TROF GOES THRU THE REGION TODAY BRINGING THE SHOWERS AND
TSTMS THAT ARE NOW IN THE MOUNTAINS AND VERMONT TO THE COAST THIS
MORNING.  UNSTABLE AIR WILL REQUIRE THE CONTINUED MENTION OF TSTMS
THIS AFTERNOON.  THE CONTINUED SOUTHERLY FLOW WILL INCREASE THE
POTENTIAL FOR LOW CLOUDS AND FOG OVER SOUTHERN SECTIONS.  A COLD
FRONT APPROACHES FROM THE WEST DURING THE NIGHT BRINGING AN
INCREASED POTENTIAL TO WESTERN SECTIONS TOWARD MORNING.
&&

.LONG TERM (THURSDAY THROUGH TUESDAY)...
FRONTAL BOUNDARY STALLS OVER THE REGION ON THURSDAY AND WILL
CONTINUE TO BE THE FOCUS OF SHOWER AND THUNDERSTORM ACTIVITY THROUGH
THURSDAY NIGHT.

STALLED FRONTAL BOUNDARY HANGS AROUND THROUGH FRIDAY AS REMNANTS OF
BONNIE MOVES NORTHEAST. TROPICAL MOISTURE FORECAST TO STREAM INTO
THE REGION...BUT MODELS NOT QUITE IN AGREEMENT AS TO WHERE BEST
QPF LIKELY TO FALL. HAVE NOT MADE ANY BIG CHANGES TO CURRENT
FORECAST AND HAVE STUCK WITH LIKELY POPS WHICH LOOK REASONABLE AT
THIS TIME.

WHOLE MESS FORECAST TO GRADUALLY SLOWLY SHIFT EASTWARD FRIDAY NIGHT
AND SATURDAY AS FRONTAL BOUNDARY FINALLY MOVES EAST OF THE REGION.
FORECAST FOR LAST HALF OF THE WEEKEND IN QUESTION DEPENDING ON HOW
FAR EAST THIS FRONT MOVES BEFORE REMNANTS OF CHARLEY HEADS INTO THE
REGION. NEW GFS KEEPS THE MAJORITY OF THE ACTION OFFSHORE BUT WOULD
NOT BE SURPRISED IF THIS SOLUTION CHANGES OVER THE NEXT FEW DAYS.
NO BIG CHANGES PLANNED FOR DAYS 5 THROUGH 7 AT THIS TIME.

&&

.MARINE...
10 TO 20 KT SOUTHERLY WINDS WILL CONTINUE TODAY AND TONIGHT.
SEAS HAVE BEEN HOLDING BETWEEN 2 AND 3 FT AND SHOULD REMAIN UNDER 5
FT THROUGH TONIGHT.  WILL NEED TO KEEP AN EYE ON LOW CLOUDS AND FOG
MOVING UP FROM THE S TONIGHT. NO PROBLEMS NOTED FOR THE THE LONG
TERM.
&&

.AVIATION...
MAINLY MID CLOUDS BUT WITH SOME VALLEY FOG FORMING.  CLOUDS
WILL LOWER AS SHOWERS AND TSTMS IN THE MOUNTAINS THRU VT WILL MOVE E
THIS MORNING.  SCATTERED AFTERNOON TSTMS AND EVENING.  THEN THERE
WILL BE THE POTENTIAL FOR COASTAL FOG DEVELOPING TONIGHT.
