SYNOPSIS
A cold front approaches tonight and moves through into early Monday morning. High pressure then builds in from the Midwest, moving across the area Tuesday as a cold front approaches from the west. The front crosses the region Wednesday night into Thursday morning. High pressure will then return for Thursday night into Friday, and move off the northeast coast Saturday as another cold front begins to approach.

NEAR TERM /UNTIL 6 AM MONDAY MORNING/
Severe Thunderstorm Watch was issued for Orange and Putnam counties until 8 pm. Main threat is damaging winds, but can't rule out large hail or even an isolated tornado. Approaching surface cold front is just beginning to push into western PA and far western NY, but will eventually advance into the local Tri- State overnight. Ahead of this a prefrontal trough is helping to initiate scattered convection late this afternoon, mainly off to the north and west, but some activity has been able to work into the lower Hudson Valley and NE NJ. Certainly a moist environment to work with as surface dew pts are near 70 and a developing LLJ will only add to the moisture in the column. SPC mesoanalysis indicates SBCAPE well over 2000 J/kg across NE NJ and the lower Hudson Valley, and effective shear values approach or exceed 40 kt in this same area, which supports at least the potential for any convection that develops to become severe.
Timing of this threat appears to be a bit later than recent days, beginning likely late this afternoon, and then persisting into the evening. Possible an additional round moves through overnight just ahead of the front based on some of the CAMs output, and this will need to be monitored.

SPC has placed the entire area in a slight risk for severe thunderstorms, with the main threats being damaging winds and isolated tornadoes. Large hail is also a threat, mainly across the Lower Hudson Valley and southern CT. Along with the severe threat, there is the threat for flash flooding with PWAT values toward two inches. The Weather Prediction Center has placed the entire area in a marginal risk for excessive rainfall, with minor flooding possible under any thunderstorm. Widespread hydro issues appear unlikely with the progressive nature of this system.

Heat Advisory remains in effect until 8 pm this evening for most zones. No extension is needed as temperatures fall back behind the cold frontal passage on Monday. Another warm night ahead of the boundary with lows mainly in the 70s.

SHORT TERM /6 AM MONDAY MORNING THROUGH MONDAY NIGHT/
Behind the fropa, surface high pressure builds in from the Midwest, offering a dry reprieve from the heat and humidity. Heights quickly fall as the ridge breaks down and a closed low trough swings east over New England.

Cooler air mass advects in on the NW flow aloft, and temperatures in the afternoon top out in the low to mid 80s for most, but will feel much more tolerable as dew pts fall a good 10 degrees from Sunday, into the low 60s. Absent a spotty shower well inland, otherwise a mostly dry day can be expected. Plenty of diurnal cu is likely to develop though as the cold pool moves overhead. Monday night is dry, with clearing skies as the surface high builds closer. Overnight lows in the 60s.

LONG TERM /TUESDAY THROUGH SUNDAY/
Key Points:

* Temperatures will remain near to just above normal, with Wednesday the warmest and most humid day of the period.

* A slow moving cold front may bring locally heavy rainfall from late day Wednesday through Wednesday night.

Global ensemble guidance continues to remain in decent agreement for next week and as such, there has not been much change to the forecast with this update. The National Blend of Models was followed closely.

Shortwave ridging on Tuesday gives way to a more zonal flow by Wednesday into Thursday. A deepening shortwave trough passes through the area on Thursday followed by weak ridging again into next weekend. Much of the week looks to remain dry, save for a frontal system that approaches from the west Wednesday night into Thursday.
The timing of this feature is perhaps a bit earlier than yesterday in the global guidance, passing through the region by 12Z Thursday.
Modeled PWATS of close to 2" (near the max for the date from SPC sounding climo.) along with a weak steering flow aloft would increase the chances of excessive rainfall for the area as the front passes through the area overnight Wednesday into Thursday. However, the probability of more than 1" in 6 hours from the NBM remains less than 10% for the entire area, perhaps hinting at a more localized threat.

While high temperatures next week will be in the upper 80s and low 90s, dewpoints in the low to mid 60s will limit the excessive heat/heat index potential. High temperatures on Wednesday look to be near 95F across the urban corridor of NYC and NJ and upper 80s elsewhere. With dewpoints in the mid to upper 60s, this will yield heat indices in the mid to upper 90s across the hottest locations.
Thereafter, the front passes through and Thursday/Friday are a bit cooler, but still above average, in the mid to upper 80s.

Dry weather returns Friday and Saturday as another high builds into the region.

AVIATION /21Z SUNDAY THROUGH FRIDAY/
A warm front to the north continues to move northward. A cold front moves into the area late tonight into Monday morning. High pressure builds in late on Monday.

Mainly VFR this eve but shwrs and tstms expected to develop.
This will bring pockets of brief MVFR conditions. Some storms could produce heavy rainfall and strong gusty winds. Expect gusty winds with any thunderstorms, and a few storms may produce gusts as high as 60 kt, although timing and areal extent is quite uncertain. Have two TEMPO group for thunderstorms; the second TEMPO group towards midnight for the city terminals and a few hours later for the more eastern terminals. Uncertainty remains higher than average for both TEMPO groups. Some lower ceilings may briefly impact far eastern terminals late in the overnight before the frontal passage.

S winds sustained around 15 kt, with gusts 25-30 kt for some southern coastal terminals. There may be an occasional higher gust near the coast. And stronger gusty winds are possible in and near thunderstorms.

NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...

Isold tstm development possibly 21-23Z. Timing and coverage of convection thru tngt remains highly uncertain.

OUTLOOK FOR 18Z MONDAY THROUGH THURSDAY...

Monday afternoon: VFR. W to NW wind G20-25 kt.

Tuesday: VFR.

Wednesday: Mainly VFR. A chance of showers and thunderstorms in the late afternoon and at night, with MVFR or lower possible. SW wind 15-20 kt G20-25 kt near the coast.

Thursday: MVFR or lower possible early with a chance of showers, then VFR.

Friday: VFR.

MARINE
Small Craft Advisory in effect for all waters but the NY Harbor. Southerly flow will continue to gust 25 to 30 kt into this evening and there may be occasional gusts to gale force on the ocean. Ocean seas approach 8 to 10 ft late tonight. A frontal passage overnight will allow winds, and eventually seas, to subside on Monday. Seas likely still linger at or above 5 ft into Monday evening before calming.

Winds and seas across all the forecast waters then remain below advisory levels Tuesday and Tuesday night. Increasing southerly winds ahead of an approaching cold front Wednesday and Wednesday night will allow for conditions on the oceans to approach SCA levels. Ocean seas may remain near SCA levels through Thursday as winds shift to west behind the cold front.

HYDROLOGY
WPC has placed the entire area in a marginal risk of excessive rainfall today. With a very humid airmass in place any thunderstorms that develop could produce heavy downpours that lead to minor, nuisance flooding. Localized flash flooding cannot be ruled out.

There is a chance for locally heavy rain from late day Wednesday afternoon into Wednesday night with a front moving through the region.

TIDES/COASTAL FLOODING
A high rip current risk continues through Monday for all ocean beaches mainly due to an energetic S swell. The risk lowers to moderate on Tuesday as seas subside and a wind trajectory offshore for much of the day.
