DISCUSSION
KEY MESSAGE 1
WARM FRONT PROGGED TO APPROACH THE AREA TODAY AND REMAIN JUST
SOUTH OR ACROSS THE FORECAST AREA THROUGH TONIGHT INTO TUESDAY
BEFORE A COLD FRONT PASSES THROUGH DURING TUESDAY. ANTICIPATING
DEEP MOISTURE POOLING ALONG THE WARM FRONT WITH PWATS INCREASING
TO AROUND 2 INCHES. WHILE CAMS STILL DISAGREE REGARDING THE
TIMING OF STORM CELLS THAT MAY PRODUCE QUICK DOWNPOURS, THERE
ARE SIGNALS AMONGST THEM/ENSEMBLE MEMBERS ALONG WITH OTHER
MODELS THAT THIS AFTERNOON AND TONIGHT WOULD BE THE MOST LIKELY
PERIODS. LIFT GETS ENHANCED WITH APPROACHING SHORTWAVES AND AN
UPPER JET STREAK DURING THIS PERIOD. THINKING IS THAT THERE IS
ENOUGH POTENTIAL FOR FLASH FLOODING TO OCCUR PRIMARILY IN
URBANIZED/POOR DRAINAGE AREAS. AFTER COLLABORATION WITH WFO PHI,
HAVE DECIDED TO ISSUE A FLOOD WATCH FOR FLASH FLOODING FOR THE
AREAS TYPICALLY PRONE TO THIS MODE OF FLASH FLOODING - NYC AND
NE NJ. WHILE IT HAS BEEN FAIRLY DRY LEADING UP TO TODAY, CREEK
AND SMALL STREAM FLOODING CANNOT BE COMPLETELY RULED OUT OVER NE
NJ. TIMING OF THE WATCH COVERS MOST OF THIS AFTERNOON AND ALL
OF TONIGHT. RAINFALL RATES THIS AFTERNOON MAY BE AS HIGH AS
AROUND 2 INCHES PER HOUR.
WITH THE COLD FRONT STILL NOT PASSING THROUGH UNTIL TUESDAY,
ADDITIONAL HEAVY DOWNPOURS ARE STILL POSSIBLE DURING TUESDAY MAINLY
EAST OF NYC. HIGHER AMOUNTS OF RAINFALL WOULD BE NEEDED TO PRODUCE
FLOODING FOR THESE SPOTS, SO NO WATCHES PLANNED FOR NOW.
ADDITIONALLY, WHILE CONFIDENCE IS STILL RELATIVELY LOW, THERE IS
POTENTIAL FOR SOME OF THESE THUNDERSTORMS THIS AFTERNOON AND EVENING
TO BECOME SEVERE. THIS IS MAINLY DUE TO THE POTENTIAL LOCATION OF
THE WARM FRONT AND DECENT LOW LEVEL CURVATURE IN MODEL HODOGRAPHS
WITH A VEERING WIND PROFILE AND SUFFICIENT SPEED SHEAR. THE MAIN
THREAT WILL BE DAMAGING WIND GUSTS, BUT CANNOT COMPLETELY RULE OUT
AN ISOLATED TORNADO DUE TO SHEAR PROFILES. THE SPC MAINTAINS A
SLIGHT RISK OF SEVERE TSTMS INTO STATEN ISLAND AND UNION COUNTY IN
NE NJ, AND A 2% TORNADO RISK INTO ALL OF NE NJ AND NYC. EXCEPT FOR
FAR EASTERN LONG ISLAND AND SE CT, THE REST OF THE AREA IS UNDER A
MARGINAL SEVERE RISK.
KEY MESSAGE 2
SOUTHWEST FLOW ALOFT LOOKS TO SET UP BY LATE THURSDAY INTO FRIDAY
AHEAD OF THE NEXT SHORTWAVE/COLD FRONT. THIS WOULD HELP TO TRIGGER
THE POTENTIAL FOR SHOWERS AND A FEW THUNDERSTORMS. CONFIDENCE IS
STARTING TO INCREASE THAT THE GREATEST POTENTIAL ENDS UP ON THURSDAY
NIGHT INTO FRIDAY WHEN THE SHORTWAVE AXIS IS CURRENTLY PROGGED TO
MOVE ACROSS THE AREA. ANY SEVERE/HYDRO IMPACTS ARE UNCERTAIN AT THIS
TIME SINCE THIS IS AROUND 5 DAYS OUT.
AVIATION /12Z MONDAY THROUGH FRIDAY/
A FRONTAL SYSTEM IMPACTS THE AREA THROUGH THE TAF PERIOD.
VFR CONDITIONS EXPECTED THROUGH THIS MORNING. MVFR CHANCES
INCREASE AS WE PROGRESS INTO THE AFTERNOON AND EVENING, WITH
IFR CONDITIONS BECOMING MORE LIKELY LATE THIS AFTERNOON THROUGH
TONIGHT. HIGHER CONFIDENCE IN LOW-END IFR TONIGHT. LIFR IS
POSSIBLE LATE TONIGHT, BUT CONFIDENCE TOO LOW TO INCLUDE AT MOST
TA SITES. MVFR PREVAILS TOMORROW.
SHOWERS BECOME POSSIBLE 15Z-19Z. THEN THUNDERSTORMS BECOME MORE
LIKELY FOR THE REMAINDER OF THE AFTERNOON AND EVENING. THEN
SHOWERS PREVAIL INTO THE NIGHT WITH A PROB30 CARRIED FOR
ADDITIONAL THUNDERSTORM CHANCES 3-6Z. LIGHT SHOWERS COULD
CONTINUE THROUGH TOMORROW MORNING. THEN 14-18Z PROB30S ARE
REINTRODUCED FOR THUNDERSTORMS.
ESE WINDS WILL BE AROUND 9-14 KT LATE THIS MORNING THROUGH
EARLY THIS EVENING. WINDS MAY BECOME MORE SOUTHERLY AS WE GET
LATER INTO THE EVENING AND INTO THE OVERNIGHT, WITH SPEEDS
DIMINISHING TO AROUND 5 KT, POSSIBLY GOING VARIABLE IN SPOTS.
WINDS N/NNW 5-10 KT TOMORROW.
...NY METRO (KEWR/KLGA/KJFK/KTEB) TAF UNCERTAINTY...
CONFIDENCE IS HIGH IN BOTH SHOWERS AND THUNDERSTORMS. HOWEVER,
MUCH OF THE PRECIPITATION IS EXPECTED TO PASS THROUGH THE AREA
IN WAVES. THE TIMING OF THESE WAVES IS VERY LOW CONFIDENCE. SO
AS NOT TO UNDERMINE THE RISK FOR THUNDERSTORMS, A LARGE PERIOD
OF PREVAILING TSRA IS MAINTAINED IN THE TAFS (19Z-3Z). JUST
KEEP IN MIND, CONFIDENCE IS TOO LOW TO PROVIDE MORE SPECIFIC
TIME RANGES FOR TSRA OCCURRENCE, AT THIS TIME. THUNDERSTORMS
REMAIN POSSIBLE INTO TONIGHT, BUT SHOWERS MAY BECOME MORE
PREVALENT AS THE NIGHT PROGRESSES, WITH LESS CHANCES FOR
THUNDER.
20KT GUSTS POSSIBLE AT CITY TERMINALS THIS AFTERNOON, BUT TOO
OCCASIONAL TO INCLUDE IN TAFS.
IFR AND GUSTY WINDS POSSIBLE WITHIN SOME THUNDERSTORMS.
OUTLOOK FOR 12Z TUESDAY THROUGH FRIDAY
TUESDAY: IFR EARLY WITH SHOWERS, IMPROVING CONDITIONS AFTERNOON
INTO EVENING. VFR EVENTUALLY RETURNS. NW WIND GUSTS NEAR 15-20
KT POSSIBLE.
WEDNESDAY: VFR WITH NW FLOW.
THURSDAY: MAINLY VFR. MVFR OR LOWER POSSIBLE AT NIGHT WITH
INCREASING CHANCES OF SHOWERS, BECOMING LIKELY LATE NORTH AND
WEST OF NYC. A CHANCE OF THUNDERSTORMS. S WIND GUSTS 15-20 KT
AFTERNOON INTO EVE.
FRIDAY: MVFR OR LOWER POSSIBLE. SHOWERS LIKELY FOR WESTERN
TERMINALS. CHANCE FOR SHOWERS ELSEWHERE. A CHANCE OF
THUNDERSTORMS. SOUTHERLY WIND GUSTS UP TO 20 KT POSSIBLE IN THE
AFTERNOON.

FORECASTS, CAN BE FOUND AT: HTTPS:/WWW.WEATHER.GOV/ZNY/N90
MARINE
S FLOW WILL STRENGTHEN TODAY AS LOW PRESSURE APPROACHES FROM THE
WEST. ALL WATERS EXCEPT THE SOUND AND PECONIC/GARDINERS BAYS REMAIN
UNDER AN SCA FROM LATE TODAY THROUGH TONIGHT, FOR GUSTS 25-30 KT AND
OCEAN SEAS UP TO 5 FT. THERE IS POTENTIAL FOR THE OTHER WATERS TO BE
ADDED IN SUBSEQUENT FORECASTS. THEREAFTER, WINDS AND SEAS SHOULD
REMAIN BELOW SCA CRITERIA.
RIP CURRENTS:
THE RIP CURRENT RISK WILL BE MODERATE FOR MUCH OF TODAY, THEN
INCREASES TO HIGH AFTER 5 PM AT THE OCEAN BEACHES OF NYC, NASSAU AND
WESTERN SUFFOLK AS S FLOW INCREASES TO 20 KT AND ASSOCIATED WIND
WAVES BUILD TO 4-5 FT, AT A TIME WHEN LIFEGUARDS AND BEACH PATROLS
WILL BE COMING OFF DUTY. RCMOS FORECAST FOLLOWED FOR THE MOST PART
AS IT IS WELL ALIGNED WITH THE TREND IN WINDS/SEAS.
A MOSTLY MODERATE RISK IS EXPECTED FOR TUESDAY AS WINDS TURN
OFFSHORE AND SEAS SLOWLY SUBSIDE, BUT THERE IS A CHANCE THAT THE
RISK IS STILL HIGH EARLY ON.
