AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CARIBOU ME
437 AM EDT SUN JUN 2 2002

.SYNOPSIS...
COOLER TEMPERATURES WILL OCCUR TODAY...IN THE WAKE OF A COLD FRONT. THE COLD
FRONT AND UPPER LEVEL DISTURBANCE CROSSING THE REGION WILL BRING THE CHANCE
OF SHOWERS TODAY. TEMPERATURES WILL REMAIN BELOW NORMAL THROUGH MONDAY.

.DISCUSSION...
CURRENT SURFACE ANALYSIS INDICATED A COLD FRONT APPROACHING WESTERN
MAINE...WITH A WAVE DEVELOPING ALONG THE FRONT ACROSS WESTERN NEW ENGLAND.
THE FRONT WILL CROSS THE REGION THIS MORNING...WITH THE WAVE INTENSIFYING
ACROSS THE MARITIMES TODAY WHILE MOVING ALONG THE FRONT. NORTHWEST WINDS IN
THE WAKE OF THE FRONT WILL TRANSPORT UNSEASONABLY COLD AIR ACROSS THE REGION
TODAY...WITH TEMPERATURES REMAINING BELOW NORMAL THROUGH MONDAY. HIGH
PRESSURE WILL BUILD TOWARD THE REGION LATER TONIGHT AND MONDAY. ALOFT...AN
UPPER LOW WILL BE CENTERED NORTH OF THE STATE TODAY...WITH TROFFING ACROSS
MAINE. A VORT MAX ROTATING THROUGH THE TROF WILL CROSS THE REGION TODAY. THE
UPPER LOW AND TROF WILL SLOWLY MOVE EASTWARD TONIGHT AND MONDAY.

SATELLITE IMAGERY INDICATED CLOUDS ALONG THE FRONTAL BOUNDARY AND DEVELOPING
WAVE...WITH AN EXTENSIVE AREA OF CLOUDINESS LOCATED JUST NORTHWEST OF MAINE
ASSOCIATED WITH THE COLD POOL IN THE VICINITY OF THE UPPER LOW. KCBW 88D
INDICATED SCATTERED SHOWERS CROSSING CENTRAL/DOWNEAST AREAS. REGIONAL RADARS
INDICATED SHOWERS EXTENDING BACK ACROSS MAINE TO NORTHERN NEW YORK
STATE...WITH A MORE EXTENSIVE AREA OF PRECIPITATION ASSOCIATED WITH THE
DEVELOPING WAVE CROSSING SOUTHERN PORTIONS OF VERMONT AND NEW HAMPSHIRE.
EXPECT THE AREA OF STEADIER PRECIPITATION TO TRACK ACROSS THE GULF OF
MAINE THIS MORNING...TRACKING JUST SOUTH OF THE FORECAST AREA.
HOWEVER...SCATTERED SHOWERS ARE POSSIBLE ACROSS THE FORECAST AREA THIS
MORNING IN ASSOCIATION WITH THE COLD FRONT. THE COMBINATION OF THE VORT MAX
CROSSING THE REGION AND INSTABILITY ASSOCIATED WITH COOLING TEMPERATURES
ALOFT WILL SUPPORT SCATTERED SHOWER DEVELOPMENT THIS AFTERNOON. THESE
FACTORS WILL ALSO SUPPORT EXTENSIVE CU/SC DEVELOPMENT. TEMPERATURES WILL BE
UNSEASONABLY COOL TODAY...WITH HIGHS RANGING FROM THE LOW 50S NORTH TO 60 TO
65 DOWNEAST.

UPPER LEVEL TROFFING WILL PERSIST ACROSS THE REGION TONIGHT...HELPING
MAINTAIN MOSTLY CLOUDY SKIES ACROSS THE NORTH AND MOUNTAINS. SKIES WILL
BECOME PARTLY CLOUDY DOWNEAST. LOWS TONIGHT WILL RANGE FROM THE UPPER 30S
NORTH TO TO THE LOWER 40S DOWNEAST.

WITH THE UPPER TROF MOVING EASTWARD MONDAY AND MODERATING TEMPERATURES
ALOFT...DIURNAL CU/SC DEVELOPMENT WILL BE LESS EXTENSIVE. HOWEVER...ENOUGH
DIURNAL CU/SC DEVELOPMENT WILL OCCUR TO PRODUCE PARTLY CLOUDY SKIES ACROSS
THE FORECAST AREA. HIGHS MONDAY WILL RANGE FROM 55 TO 60 NORTH TO THE MID
60S DOWNEAST.

HIGH PRESSURE WILL BUILD ACROSS THE REGION MONDAY NIGHT AND PERSIST THROUGH
TUESDAY. LOW PRESSURE LIFTING TOWARD THE REGION WILL BRING A CHANCE OF
RAIN WEDNESDAY...WITH A CHANCE OF LINGERING SHOWERS THROUGH THE END OF
THE WEEK.

COASTAL WATERS...
SMALL CRAFT ADVISORY LEVEL WINDS AND SEAS WILL OCCUR TODAY...THEN DIMINISH
LATER TONIGHT. VISIBILITIES COULD BE LOCALLY REDUCED IN SCATTERED SHOWERS
TODAY. AN ISOLATED THUNDERSTORM IS ALSO POSSIBLE THIS MORNING.
