DISCUSSION
KEY MESSAGE 1
A WEAK FRONTAL SYSTEM MOVES THROUGH THE AREA TODAY LIKELY BRINGING
ABOUT A TENTH OF AN INCH OF RAIN. THE SHOWERS OUT THERE
CURRENTLY HAVE BEEN FIGHTING DRY AIR IN THE LOW LEVELS AND NOT
MUCH HAS BEEN REACHING THE GROUND. THERE ARE SEVERAL SITES WHO
HAVE REPORTED NO RAIN EVEN AFTER A FEW HOURS AND DECENT RETURNS.
FORECAST SOUNDINGS SHOW THE COLUMN SATURATING EARLY THIS
MORNING. LATEST CAMS ARE IN GOOD AGREEMENT WITH TIMING OF
SHOWERS BEING MAINLY IN THE MORNING AND EARLY AFTERNOON HOURS.
STUCK CLOSE TO NBM POPS.
THE COMBINATION OF A COOL ONSHORE FLOW AND PLENTY OF CLOUDS WILL
KEEP TEMPERATURES ABOUT 5 TO 10 DEGREES BELOW NORMAL. HIGHS ARE
FORECAST TO BE IN THE UPPER 40S FOR EASTERN LI AND MUCH OF
SOUTHERN CT WITH 50S ELSEWHERE.
KEY MESSAGE 2
METEOROLOGICAL CONDITIONS SUPPORT THE POTENTIAL FOR ELEVATED RISK OF
FIRE SPREAD FOR THURSDAY. A WEAK COLD FRONT MOVES THROUGH IN THE
AFTERNOON AND FORECAST SOUNDINGS SHOW DEEP MIXING. TDS DROP TO THE
30S RESULTING IN MIN RH VALUES NEAR 30 PERCENT. DEEP MIXING IN THE N
FLOW LOOKS TO HAVE POTENTIAL FOR 25 TO 30 MPH GUSTS WITH ISOLATED
HIGHER GUSTS.
THIS THREAT LOOKS HIGHEST FOR NORTHERN LOCATIONS LIKE SOUTHERN CT
AND THE LOWER HUDSON VALLEY WHERE THE FRONT WILL MOVE THROUGH
EARLIER.
KEY MESSAGE 3
GUIDANCE HAS BEEN CONSISTENT WITH A FRONTAL SYSTEM SLIDING SOUTH OF
THE AREA ON SATURDAY AND BRINGING RAIN TO AT LEAST TO NYC NORTH AND
WEST. THERE IS STILL SOME UNCERTAINTY WITH HOW FAR EAST THE PRECIP
SHIELD WILL GET, BUT THERE WILL LIKELY BE A DECENT GRADIENT.
REGARDLESS, THE EASTERLY FLOW WILL KEEP TEMPERATURES IN THE LOW 50S
FOR MOST. THERE IS SOME INDICATION THAT EASTERN CT COULD GET INTO
THE UPPER 50S IF THE BULK OF PRECIP AND CLOUDS STAY FARTHER WEST.
THE LARGE SPREAD FOR THIS EVENT LIES WITH THE AMOUNT OF RAIN THAT WE
COULD SEE. THE LATEST NBM 24HR QPF 10TH PERCENTILE FOR NYC
SHOWS 0.00 INCHES WITH THE 90TH PERCENTILE SHOWING AROUND 1
INCH. THIS IS EXPECTED TO FALL OVER A 18-24 HOUR PERIOD SO
FLOODING IS NOT A CONCERN AT THIS TIME.

TERMINALS THIS AFTERNOON. A WEAK AREA OF LOW PRESSURE WILL FORM

SOME MVFR CONDITIONS WITH THE BEST CHANCES FROM ABOUT 12Z-15Z.
MVFR CONDITIONS BECOME LIKELY AS THE FRONT APPROACHES THIS
AFTERNOON. THERE MAY BE A PERIOD LATE THIS AFTERNOON AND THIS
EVENING WHERE CONDITIONS FALL TO IFR AT THE NYC TERMINALS.
IFR CONDITIONS ARE MORE LIKELY AT THE SURROUNDING/COASTAL
TERMINALS. CONDITIONS SHOULD BEGIN TO IMPROVE LATE WEDNESDAY
NIGHT OR EARLY THURSDAY MORNING.
SE-S FLOW AROUND 10-15 KT EXPECTED. SOME TERMINALS, ESPECIALLY
ALONG THE COAST COULD SEE GUSTS TO AROUND 20KT OR SO THROUGH
THIS MORNING. THE GUSTS WILL DIMINISH AND THE WINDS WILL SHIFT
TO THE E THEN NE AS THE LOW PASSES SOUTH OF LONG ISLAND THIS
AFTERNOON. THERE IS SOME UNCERTAINTY WITH WIND DIRECTION DUE TO
WHERE EXACTLY THE LOW TRACKS, BUT WINDS ARE EXPECTED TO BE
