NEAR TERM /THROUGH TONIGHT/
A SHORT WAVE TROUGH IS CURRENTLY SLIDING ACROSS NORTHERN NEW
ENGLAND WITH COOLER AIR ALOFT AIDING IN THE SLIGHT
DESTABILIZATION OF THE ATMOSPHERE. THIS HAS ALLOWED CU TO
BLOSSOM OVER THE AREA WITH ISOLATED SHOWERS OVER THE MOUNTAINS.
A WEAK COLD FRONT WILL PRESS SOUTHEAST THROUGH THE AREA AND MAY
ALLOW FOR SOME ISOLATED SHOWERS TO DEVELOP OVER THE COASTAL
PLAIN. CLOUDS AND ISOLATED SHOWERS WILL DISSIPATE LATER THIS
EVENING WITH THE LOSS OF HEATING. OTHERWISE VALLEY FOG WILL BE
POSSIBLE LATE TONIGHT WITH LOWS IN THE 40S TO LOW 50S.
SHORT TERM /MONDAY THROUGH MONDAY NIGHT/
HIGH PRESSURE BUILDS IN MONDAY FOR FAIR WEATHER. HIGHS WILL
GENERALLY BE IN THE 70S WITH LIGHT WINDS TURNING ONSHORE.
HIGH PRESSURE SETTLES OVERHEAD MONDAY NIGHT WITH LOWS AROUND 40
ACROSS THE NORTH AND 50 DEGREES ACROSS THE SOUTH. VALLEY FOG
WILL BE LIKELY MONDAY NIGHT. OTHERWISE QUIET WEATHER CONTINUES.
LONG TERM /TUESDAY THROUGH SUNDAY/
OVERVIEW...
HIGH PRESSURE REMAINS IN CONTROL MUCH OF THE WEEK, WHILE LOW
PRESSURE STALLS SOUTH OF NEW ENGLAND ALONG THE MID ATLANTIC
COAST. A COLD FRONT MOVES THROUGH LATE IN THE WEEK. HIGH
PRESSURE ORIGINATING FROM THE ARCTIC MOVES IN BEHIND THE FRONT
FOR THE WEEKEND.
DETAILS...
HIGH PRESSURE SLOWLY DRIFTS TO THE EAST ON TUESDAY AND
WEDNESDAY, BRINGING A MODERATING TREND THROUGH THE WEEK ON
SOUTHWESTERLY FLOW. HIGHS WARM INTO THE 70S TO NEAR 80 ON
TUESDAY, WITH LOW 80S BECOMING MORE WIDESPREAD FOR WEDNESDAY AND
THURSDAY. NIGHTTIME LOWS ALSO MODERATE, WITH 40S AND 50S BEING
MORE COMMON THAN THE LAST FEW NIGHTS. AT THE SAME TIME, LOW
PRESSURE STALLS ACROSS THE MID ATLANTIC, KEEPING ANY RAINFALL
WELL SOUTH OF NEW ENGLAND.
A COLD FRONT THEN MOVES THROUGH NEW ENGLAND. WITH THE STORM
TRACK AND MOISTURE REMAINING WELL TO THE SOUTH, THE FRONT LOOKS
TO BRING LITTLE MORE THAN SOME CLOUDS AND A FEW SHOWERS ACROSS
THE HIGHER TERRAIN. THE FRONT LIKELY MOVES THROUGH DURING THE
THURSDAY NIGHT TO EARLY FRIDAY TIMEFRAME, WITH COOLER AIR MOVING
IN DURING THE DAY ON FRIDAY. WITH DRY CONDITIONS WORSENING
THROUGH THE WEEK, FIRE WEATHER CONDITIONS WILL BE WORST THIS
WEEK ON FRIDAY WITH A NORTHWESTERLY BREEZE AND FALLING DEW
POINTS THROUGH THE DAY.
HIGH PRESSURE ORIGINATING FROM THE ARCTIC MOVES BEHIND THE
FRONT FOR THE WEEKEND. HIGHS IN THE 60S LOOK LIKELY WITH DRY
CONDITIONS, AND WIDESPREAD NIGHTTIME LOWS IN THE 30S. IT'S STILL
ALMOST A WEEK AWAY AND WILL NEED TO BE MONITORED IN THE COMING
DAYS, BUT IF THE HIGH PRESSURE CENTER CROSSES NEW ENGLAND
OVERNIGHT ON SATURDAY NIGHT A WIDESPREAD FROST/FREEZE WOULD BE
LIKELY ACROSS MUCH OF THE INTERIOR AS LOWS DROP INTO THE UPPER
20S TO LOW 30S. AGAIN, IT'S STILL TOO EARLY TO CALL FOR THIS A
THIS POINT, BUT WITH THE COLD ORIGIN OF THE AIRMASS AND DRY
ANTECEDENT CONDITIONS THE POTENTIAL IS THERE AND WILL NEED TO
MONITORED THROUGH THE WEEK.
