WHAT HAS CHANGED
LOWERED TEMPERATURES TONIGHT TO REFLECT OBSERVATIONAL TRENDS.
KEY MESSAGES
1. FAIR WEATHER AND NEAR NORMAL TEMPERATURES WILL DOMINATE THE
WEATHER THIS WEEK. A NOR'EASTER OFF THE MID ATLANTIC COAST MAY
EVENTUALLY ALLOW FOR BLUSTERY WINDS AND BUILDING NEARSHORE
WAVES FOR THE LATTER HALF OF THE WEEK.
DISCUSSION
KEY MESSAGE 1 DESCRIPTION...
HIGH PRESSURE OVERHEAD WILL ALLOW FOR RADIATIONAL COOLING
TONIGHT. RADIATIONAL COOLING CONDITIONS ARE ALREADY OCCURING,
WITH MOST PLACES REPORTING CALM AND CLEAR SKIES IN MANY PLACES.
TEMPERATURES THIS EVENING ARE ALREADY RUNNING A FEW DEGREES
BELOW THE FORECAST, SO I HAVE CONTINUED TO LOWER LOW
TEMPERATURES WITH THESE TRENDS. THIS MORNING, EXPECT TO WAKE UP
TO TEMPERATURES IN THE TEENS NORTH OF THE MOUNTAINS AND MID-20S
ELSEWHERE.
STARTING ON SUNDAY, AN UPPER-LEVEL TROUGH EXITS THE
NORTHEASTERN US AND IS REPLACED BY A BROAD RIDGE. IN GENERAL,
UPPER-LEVEL RIDGING SHOULD ALLOW FOR TEMPERATURES TO BE MORE
MILD THROUGH MUCH OF NEXT WEEK AND TEMPERATURES DO LOOK TO RUN A
LITTLE ABOVE AVERAGE ON SUNDAY AND MONDAY.
A NOR'EASTER WELL OFFSHORE COULD USHER ENOUGH MOISTURE INTO THE
AREA MONDAY NIGHT THAT A FOG BANK MAY BUILD OVER THE COASTAL
PLAIN. IF FOG DEVELOPS, IT COULD LINGER AT LEAST THROUGH THE
LATE MORNING ON TUESDAY. THE NOR'EASTER ITSELF WILL STAY SOUTH
AND WILL NOT BRING MEANINGFUL WINDS NOR PRECIPITATION TO
NORTHERN NEW ENGLAND.
HOWEVER, HIGH PRESSURE TO THE NORTH ESPECIALLY TOWARDS THE
MIDDLE OF NEXT WEEK MAY LEAD TO MORE SEASONABLE TEMPERATURES
THEN. NO PRECIPITATION IS FORECAST NEXT WEEK.
AVIATION /03Z SUNDAY THROUGH THURSDAY/
THROUGH 06Z MONDAY...PERSISTENT HIGH PRESSURE OVERHEAD WILL
ALLOW FOR VFR CONDITIONS TO CONTINUE THROUGH TONIGHT.
OUTLOOK:
MONDAY: VFR EXPECTED.
MONDAY NIGHT: VFR EXPECTED NORTH OF THE MOUNTAINS. A NOR'EASTER
WELL OFFSHORE COULD ALLOW FOR COASTAL FOG AND LOW STRATUS.
TUESDAY-THURSDAY: VFR EXPECTED.
MARINE
HIGH PRESSURE REMAINS OVERHEAD THROUGH SUNDAY NIGHT, KEEPING
CONDITIONS TRANQUIL INTO MONDAY. BY LATE MONDAY INTO MONDAY
NIGHT, THE GRADIENT STARTS TO TIGHTEN FROM HIGH PRESSURE TO THE
NORTHWEST AND A NOR'EASTER OFF THE COAST OF THE CAROLINAS, AND
SCA CONDITIONS ARE POSSIBLE FROM INCOMING SWELLS AND INCREASING
NORTH TO NORTHEAST WINDS THROUGH MIDWEEK. WIND GUSTS AND SWELLS
MAY BECOME ELEVATED IT AGAIN LATE WEEK AS THE NOR'EASTER PASSES
EAST OF THE GULF OF MAINE.
