FORECAST UPDATE
ISSUED AT 947 AM EDT SAT OCT 3 2026
FORECAST IS IN GREAT SHAPE THIS MORNING. HIGH PRESSURE WILL PROVIDE
PLENTIFUL SUNSHINE AND DRY CONDITIONS TODAY. WITH A DRY ATMOSPHERE
AND THE SUNSHINE, TEMPERATURES WILL REBOUND NICELY TO FORECAST
HIGHS. TWEAKED HOURLY FORECASTS TO MATCH LATEST OBSERVATIONS, BUT
OTHERWISE NO CHANGES WERE MADE.
DISCUSSION (TODAY THROUGH FRIDAY)
ISSUED AT 112 AM EDT SAT OCT 3 2026
AUTUMN ANNOUNCES ITSELF IN A BIG WAY THROUGH THE NEXT WEEK, WITH
MUCH MILDER CONDITIONS AND A PROLONGED DRY SPELL UNDER THE INFLUENCE
OF TWO STRONG AREAS OF SURFACE HIGH PRESSURE.
DRY WEATHER IS FORECAST THROUGHOUT THE NEXT SEVEN DAYS DUE TO THE
EXPANSIVE INFLUENCE OF THE AFOREMENTIONED SURFACE HIGH PRESSURE.
BROADLY CYCLONIC FLOW WILL BE IN PLACE OVER THE REGION, THOUGH ANY
FORCING SHORTWAVE TROUGHS PIVOTING THROUGH THIS FLOW WILL BE
DISPLACED WELL TO THE NORTH, LEAVING THE PRIMARY IMPACT TO THE AREA
TO BE MUCH MILDER TEMPERATURES THROUGH THE PERIOD.
SOME MODERATION OF TEMPERATURES IS EXPECTED MID TO LATE NEXT WEEK,
WITH 80 DEGREE READINGS LIKELY PUSHING BACK INTO PORTIONS OF THE
REGION, BUT SUBSTANTIALLY LESS HUMID CONDITIONS THAN EXPERIENCED IN
RECENT WEEKS. THIS LEAVES THE PRIMARY WEATHER HAZARD OF CONCERN AS
FIRE CONDITIONS, WITH AFTERNOON RELATIVE HUMIDITY VALUES LIKELY TO
DROP INTO THE 30 PERCENT RANGE ON MANY IF NOT MOST DAYS, AND
POSSIBLY EVEN LOWER AS BLENDED GUIDANCE OFTEN STRUGGLES TO FULLY
CAPTURE THE DEGREE OF MIXING OUT OF DEWPOINTS IN THE AFTERNOONS WITH
PLENTIFUL SUNSHINE, EVEN IN SETTINGS WITH RELATIVELY LIGHT SURFACE
FLOW.
ADDITIONALLY, THERE IS AT LEAST A LOW CHANCE FOR PATCHY FROST MAINLY
NORTHEAST MONDAY NIGHT INTO TUESDAY MORNING AS LOWS WILL HAVE THE
POTENTIAL TO DROP INTO THE UPPER 30S. CURRENT NUMBERS APPEAR TOO
WARM TO SUPPORT ANYTHING WIDESPREAD OR SIGNIFICANT, BUT IF WE CAN
DROP A COUPLE/FEW MORE DEGREES IN THE OUTLYING AREAS THIS MAY BE ON
THE TABLE.
IN ANY CASE, SEVERAL DAYS OF PLEASANT AUTUMN WEATHER ARE EXPECTED
OVER THE NEXT WEEK, AND ALL ARE ENCOURAGED TO ENJOY THE ABRUPT SHIFT
INTO MILD FALL DAYS AND COOL NIGHTS.
