DISCUSSION
KEY MESSAGE 1
DAYTIME HIGH TEMPERATURES TREND FROM BELOW NORMAL FRIDAY TO NEAR
NORMAL SATURDAY AND THEN MORE ABOVE NORMAL SUNDAY AND MONDAY. DRY
CONDITIONS ARE FORECAST TO PREVAIL.
MID LEVELS FROM NUMERICAL WEATHER PREDICTION MODELS INDICATE RISING
HEIGHTS INTO THE WEEKEND. TROUGH EXITS EAST OF THE CANADIAN
MARITIMES WITH RIDGE MOVING IN FROM THE WEST. THE RIDGING WEAKENS
LATE THIS WEEKEND INTO EARLY NEXT WEEK. AT THE SURFACE, THE LOW
PRESSURE ASSOCIATED WITH JOSEPHINE MOVES WELL OUT INTO THE
NORTHERN ATLANTIC AND EAST OF CANADIAN MARITIMES THROUGH FRIDAY
AS HIGH PRESSURE BUILDS IN FROM THE NORTH ACROSS OUR LOCAL REGION.
STRONG SURFACE HIGH PRESSURE WILL BE THE MAIN FEATURE HEADING
INTO THE WEEKEND WITH PREVAILING DRY CONDITIONS. THE PRESSURE
GRADIENT WILL GRADUALLY WEAKEN ALLOWING FOR LIGHTER WINDS. THIS
WILL FURTHER ALLOW FOR GREATER DAYTIME INSOLATION AND GREATER
NIGHTTIME RADIATIONAL COOLING WITH A MORE VAST RANGE IN
TEMPERATURE BETWEEN MAX AND MIN.
SURFACE HIGH PRESSURE WEAKENS AND SHIFTS FARTHER SOUTH AND WEST
SUNDAY NIGHT INTO EARLY NEXT WEEK. DRY CONDITIONS PREVAIL THROUGH
THIS WEEKEND AND INTO NEXT WEEK DESPITE A COLD FRONT MOVING
ACROSS LATE MONDAY INTO MONDAY NIGHT. TEMPERATURES WARM UP FOR
DAYTIME HIGHS THIS WEEKEND AND INTO EARLY NEXT WEEK. WARMEST
DAY LOOKS TO BE MONDAY WITH MODELS SHOWING RELATIVELY HIGHEST
850MB TEMPERATURES NEAR 11 TO 13 DEGREES C. SOME LOCATIONS ARE
FORECAST TO REACH NEAR 70 DEGREES FAHRENHEIT FOR MONDAY'S HIGHS.
THAT IS THE WARMEST DAY OF THE FORECAST PERIOD THROUGH NEXT
WEEK.
KEY MESSAGE 2
WITH MORE RADIATIONAL COOLING EACH NIGHT, TEMPERATURES IN OUTLYING
AREAS AND RURAL SECTIONS WILL DROP FURTHER.
FROST IS EXPECTED TO DEVELOP IN THESE AREAS, MAINLY ACROSS THE
NORTHERN HALF OF THE FORECAST AREA. FOR TONIGHT, PATCHY FROST IS
FORECAST ACROSS PARTS OF THE INTERIOR AND WILL BE LIMITED IN SPATIAL
EXTENT DUE TO WINDS STAYING UP IN THE BOUNDARY LAYER. LOWS
TONIGHT RANGE FROM MID 30S TO UPPER 40S FOR MUCH OF THE AREA.
LARGER AREAS OF FROST FORECAST LATE FRIDAY NIGHT INTO EARLY SATURDAY
MORNING AS WELL AS LATE SATURDAY NIGHT INTO EARLY SUNDAY MORNING
MAINLY ACROSS THE INTERIOR, COASTAL CT AND WITHIN SUFFOLK COUNTY NY.
FROST FORMATION SUNDAY NIGHT INTO EARLY MONDAY MORNING IS FORECAST
TO BE MORE RESTRICTED TO THE INTERIOR ZONES AS MORE SW SURFACE WINDS
DEVELOP BUT STAY LIGHT. HIGH PRESSURE WILL BE WEAKENING FOR THIS
TIMEFRAME ACROSS THE LOCAL REGION AS IT SHIFTS FARTHER SOUTH AND
WEST OF THE REGION. FORECAST LOWS SUNDAY NIGHT RANGE ACROSS
LONG ISLAND MORE IN THE UPPER 30S TO LOWER 50S AS A RESULT.
NOW WE ALREADY HAVE ENDED THE GROWING SEASON ACROSS INTERIOR
SOUTHERN CT, ORANGE NY, PUTNAM NY, ROCKLAND NY, NORTHERN
WESTCHESTER NY, PASSAIC NJ, WESTERN BERGEN NJ, WESTERN ESSEX NJ,
WESTERN UNION NJ AS OF OCTOBER 21ST.
FOR THOSE ZONES STILL WITH AN ACTIVE GROWING SEASON, THE ZONES
WITH THE RELATIVELY HIGHER CHANCE OF MEETING THRESHOLDS FOR
FROST ADVISORY AND PERHAPS EVEN FREEZE HEADLINES WOULD BE
EASTERN SUFFOLK WITH LOWS FOR PORTION OF SUFFOLK, PRIMARILY
AROUND THE PINE BARRENS INTO START OF TWIN FORKS, FORECAST TO
DROP INTO THE UPPER 20S TO LOWER 30S ALONG WITH AREAS OF FROST
FORECAST. THIS AREAL EXTENT OF THIS AT THIS POINT FORECAST TO BE
LESS THAN HALF OF THE ZONE SO THERE ARE NO HEADLINES ISSUED
REGARDING THIS AT THIS TIME.
KEY MESSAGE 3
WITH THE APPROACH OF A FULL MOON LATE THIS WEEKEND AND A PERSISTENT
EASTERLY SWELL WATER LEVELS WILL BE ELEVATED THROUGH THE NEXT
SEVERAL HIGH TIDE CYCLES. BRIEF MINOR FLOODING OF THE MORE
VULNERABLE LOCATIONS NEAR THE WATERFRONT AND SHORELINE IS POSSIBLE
FOR THE NASSAU SOUTH SHORE BAYS WITH THE FRIDAY MORNING HIGH TIDE
CYCLE. THUS A COASTAL FLOOD STATEMENT FOR THE FRIDAY MORNING HIGH
TIDE HAS BEEN ISSUED FOR THIS POSSIBILITY. SUBSEQUENT HIGH TIDE
CYCLES THROUGH EARLY SATURDAY ARE EXPECTED TO GET NEAR MINOR COASTAL
FLOOD BENCHMARKS. THEREFORE ADDITIONAL COASTAL FLOOD HEADLINES MAY
BE NEEDED OVER THE NEXT FEW DAYS.
