Area Forecast Discussion National Weather Service New York NY 907 AM EDT Sat Jun 12 2021

SYNOPSIS. High pressure across the area today will gradually retreat offshore through Sunday. A warm front then approaches from the west late Sunday and sluggishly moves across the area on Monday. A trough of low pressure will linger nearby on Tuesday followed by a cold front late Tuesday. High pressure will build gradually Wednesday into Thursday. A warm front will push through late in the week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Showers as forecast are running from interior SW CT to coastal SE CT. Any rainfall will be very light.

An upper low over eastern Canada will send a shortwave trough off the New England coast later this morning, brining clouds and a few showers to the area this morning. The best chance will be across interior and SE CT.

Clouds will likely linger for much of the day with clearing from this east this afternoon as some drier air filters in behind the passing disturbance. Clouds will be more prevalent north and west of NYC as onshore flow and moisture gets trapped beneath a strengthening inversion.

For highs today, MOS was much cooler, while the NBM considerably warmer. Used a blend of the two, starting a trend toward being cooler. Highs will mainly be in the lower 70s. This is a slight downward adjustment from the previous forecast.

SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/. An amplifying upper ridge across the western half of the country will send a digging shortwave trough from central Canada southeast across the upper Midwest and Great Lakes late Sunday, sending a surface warm front toward the area. Warm advection ahead of the front will bring showers and possibly an isolated thunderstorm to the area Sunday night into Monday. The warm front sluggishly works across the area on Monday. There could be enough clearing in the warm sector north and west of NYC Monday aft/eve to produce a round of strong and/or severe thunderstorms ahead of an approaching cold front. Increasing instability and deep-layer shear around 50kt will be present.

For Sunday, clouds will slowly increase from the west with a partly to mostly sunny day, especially east of NYC and the Lower Hudson Valley. Highs and lows will be near seasonable levels. Once gain, aired toward a blend of the NBM and MOS. Monday looks to be cooler along the coast with the warm front in close proximity, but NYC and points north and west may warm sector, with highs approaching 80. However, there is uncertainty with the warm frontal passage timing which will have an impact on temperatures.

LONG TERM /MONDAY NIGHT THROUGH FRIDAY/. For Monday evening after some leftover instability in the evening, before the cold front gets through some showers and thunderstorms will be around. Once the cold front gradually pushes through later at night the chance for any convection will wane from west to east, with mainly just some showers leftover. On Tuesday with some drying into the lower levels on a northwest flow, much of the day should be dry. However, with a cold pool aloft and a surface trough lingering nearby cannot rule out some scattered showers / convection. By Tuesday night the last of any weak surface boundaries will push through. High pressure will then follow for the mid week with seasonable temperatures and comfortable humidity levels.

By Friday a warm front should move through as a warmer southwest flow gets established into the start of next weekend. At this point Friday should remain mainly dry, although into the start of next weekend there may be a shower / thunderstorm chance as a cold front approaches.

AVIATION /13Z SATURDAY THROUGH WEDNESDAY/. Mainly VFR through the TAF period. Brief MVFR is possible this morning. MVFR conditions are possible at KGON late tonight, otherwise VFR.

Light NE-E winds this morning, mainly around 5 kts. The winds then veer to the E-SE this morning/early afternoon, then more toward the SE by late in the day. Speeds mainly 7 to 10 kt. The winds are expected to be light tonight as the winds continue to veer to the south.

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

MVFR ceilings may linger into the early afternoon.

OUTLOOK FOR 12Z SUNDAY THROUGH WEDNESDAY. Sunday. Mainly VFR during the day, but MVFR or lower in showers and thunderstorms towards evening. Sunday night. Mainly MVFR or lower in showers. Thunderstorms possible. Monday-Tuesday. Chance of MVFR. Chance of showers and isolated to scattered thunderstorms. Wednesday. VFR.

MARINE. An easterly flow of 10 to 15 kt on the ocean will bring seas to around 4 ft today before gradually subsiding tonight into Sunday in a weaker southerly flow. Winds and seas will remain below SCA levels through Monday. High pressure over the waters today will gradually give way to a weak frontal system that impacts the area late Sunday into Monday.

A southwest flow Monday night will turn more westerly into Tuesday. Seas and winds will be below SCA criteria. Behind a cold front Tuesday night the winds will switch to the NW and should remain below SCA criteria with seas briefly building to 4 ft on the ocean. With high pressure building south of the waters into Wednesday and Thursday sub SCA conditions will continue with ocean seas settling to around 2-3 ft.

HYDROLOGY. No hydrologic impacts are currently expected through next week.

TIDES/COASTAL FLOODING. There is a moderate risk for rip current development on the Atlantic Beaches this weekend.
