SYNOPSIS
A LOW PRESSURE SYSTEM IS CURRENTLY LOCATED IN NEW BRUNSWICK AND
IS EXPECTED TO GRADUALLY WEAKEN AND MOVE EAST ACROSS THE
MARITIMES TODAY. LOW PRESSURE EXITS THE MARITIMES MONDAY. HIGH
PRESSURE WILL CROSS THE REGION TUESDAY THROUGH WEDNESDAY, THEN
BEGIN TO EXIT THURSDAY.
NEAR TERM /THROUGH TONIGHT/
VERTICALLY STACKED AND WEAKENING LOW PRESSURE SYSTEM LINGERS
OVER NEW BRUNSWICK EARLY THIS MORNING, AND THEN MOVES OUT TO
NOVA SCOTIA BY THIS AFTERNOON. A FEW RAIN SHOWERS LINGER IN
NORTHERN COUNTIES DUE TO WRAP AROUND MOISTURE FROM THE LOW
SYSTEM TRACK. WINDS STAY RELATIVELY LIGHT AND FROM THE
NORTHWEST. DRIER AIR IN THE MID-LEVELS BEGINS TO BUILD IN
TODAY, BUT PLENTY OF LOW-LEVEL MOISTURE INDICATES MOSTLY
OVERCAST SKIES. HIGH TEMPERATURES TODAY IN THE MID-50S
THROUGHOUT THE AREA.
TONIGHT, LOW PRESSURE SYSTEM MOVES OUT INTO THE ATLANTIC, AS
HIGH PRESSURE TO OUR WEST BEGINS TO MOVE EAST TOWARDS NEW
ENGLAND. A FEW RAIN SHOWERS IN EASTERN MAINE ARE POSSIBLE AS
SYSTEM WRAPS AROUND A LITTLE MORE MOISTURE. SKIES ARE FORECAST
TO BE PARTLY CLOUDY, BUT IF BREAKS IN CLOUDS DO OCCUR,
TEMPERATURES COULD DROP A LITTLE LOWER DUE TO RADIATIONAL
COOLING. THERE IS A POTENTIAL FOR SOME PATCHY FROST IN THE
NORTHWESTERN PORTIONS OF MAINE, WHICH COULD IMPACT ANY AGRICULTURE.
ALSO, LOOKING AT A POTENTIAL FOR SOME PATCHY FOG DEVELOPMENT
OVERNIGHT DUE TO LIGHT WIND AND HIGH RELATIVE HUMIDITY.
OVERNIGHT LOW TEMPERATURES IN THE MID-30S IN THE NORTHWEST, AND
LOW-TO-MID 40S IN THE NORTH AND EAST.
SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/
VERTICALLY STACKED SURFACE/UPPER LOWS WILL EXIT ACROSS THE
MARITIMES MONDAY WITH UPPER LEVEL TROFFING EXTENDING BACK
ACROSS THE FORECAST AREA. GENERALLY EXPECT PARTLY SUNNY SKIES
MONDAY. HOWEVER, WITH DIURNAL HEATING AND LINGERING COLD AIR
ALOFT WITH THE UPPER TROF, COULD HAVE ENOUGH INSTABILITY TO ALSO
SUPPORT THE SLIGHT CHANCE/CHANCE OF MOSTLY AFTERNOON SHOWERS.
HIGH PRESSURE BUILDS TOWARD THE REGION MONDAY NIGHT. COULD STILL
HAVE THE SLIGHT CHANCE OF A SHOWER EARLY MONDAY NIGHT.
OTHERWISE, EXPECT PARTLY CLOUDY/MOSTLY CLEAR SKIES. HIGH
PRESSURE WILL BUILD ACROSS THE REGION TUESDAY THROUGH TUESDAY
NIGHT WITH MOSTLY CLEAR SKIES. EXPECT NEAR NORMAL LEVEL
TEMPERATURES MONDAY, WITH ABOVE NORMAL LEVEL TEMPERATURES
TUESDAY.
LONG TERM /WEDNESDAY THROUGH SATURDAY/
HIGH PRESSURE REMAINS ACROSS THE REGION WEDNESDAY THROUGH
WEDNESDAY NIGHT. EXPECT MOSTLY SUNNY SKIES WEDNESDAY, THEN
MOSTLY CLEAR/PARTLY CLOUDY WEDNESDAY NIGHT. HIGH PRESSURE BEGINS
TO EXIT THURSDAY, WITH LOW PRESSURE THEN STARTING TO APPROACH
LATE. EXPECT INCREASING CLOUDS THURSDAY. COULD ALSO HAVE A
SLIGHT CHANCE OF SHOWERS LATE ACROSS WESTERN PORTIONS OF THE
FORECAST AREA. UNCERTAINTY EXITS THURSDAY NIGHT INTO FRIDAY
REGARDING HOW RAPIDLY THE LOW APPROACHES. EXPECT INCREASING
SHOWER CHANCES THURSDAY NIGHT. THE SYSTEM SHOULD THEN BEGIN TO
CROSS THE REGION FRIDAY INTO SATURDAY WITH SHOWERS OR A
STEADIER RAIN. TEMPERATURES WILL BE AT ABOVE NORMAL LEVELS
WEDNESDAY/THURSDAY, WITH NEAR NORMAL LEVEL TEMPERATURES
FRIDAY/SATURDAY.
