SYNOPSIS. High pressure builds in from the west overnight. High pressure will weaken Tuesday with a cold front from the north then approaching the region. The cold front moves across Tuesday night. Weak high pressure builds in Wednesday. A cold front approaches on Thursday and passes through Thursday night into Friday. High pressure then builds in through Saturday before another frontal system approaches late on Sunday.

NEAR TERM /UNTIL 6 AM TUESDAY MORNING/. Some residual smoke/haze causing a reduction in visibility (5-6sm) for northern areas overnight. Otherwise, with high pressure at the surface building in from the west, expecting mostly clear sky conditions tonight. Along with decreasing winds, radiational cooling will be optimized. Some patchy fog also possible for these far outlying areas overnight with radiational cooling.

Mid and upper level westerly flow will keep a dry airmass in place. Dewpoints will stay well down into 60s and even upper 50s overnight. A MAV/MET MOS blend was used for low temperatures to resolve a more vast range of temperatures between the urban heat island and outlying rural sections. Lows range from the upper 50s to near 60 for outlying rural sections to low to mid 70s within NYC.

SHORT TERM /6 AM TUESDAY MORNING THROUGH TUESDAY NIGHT/. High pressure at the surface will gradually weaken on Tuesday. A cold front will approach from the north and move across Tuesday night. Drier air at the surface will still be present with lowering dewpoints going into the morning and early afternoon. Forecast 850mb temperatures are expected to reach 17 to 18 degrees C. Highs were a blend of NBM and MOS consensus in the upper 80s to lower 90s. Dewpoints staying mostly in the lower 60s will keep heat indices close to actual temperatures.

Showers and thunderstorms will become probable for interior areas late in the afternoon, but across the whole region Tuesday night as the cold front moves closer to the region. Thunder chances highest for the first half of the night between 8PM Tuesday and 2AM Wednesday. Instability will be limited and will decrease more late at night so after 2AM, thunder chances become slight with a continued chance of showers.

Vertical forcing increases most Tuesday night with positive vorticity advection in the mid levels. Bulk shear will be increasing 0-6km to 30-40 kt so some thunderstorms could be strong with gusty winds. Highest instability at the surface will be in the southern half of the region with around 1000 to 1500 J/kg of CAPE and less to the north. Most of the upper level energy seems to be focused to the north of the region where the height falls will be more and omega will be higher. There is a marginal risk of severe thunderstorms across parts of the Lower Hudson Valley and Southern Connecticut.

Lows Tuesday night were taken from a consensus of all guidance with temperatures ranging from the lower 60s across the interior to upper 60s and lower 70s along and near the coast as well as NYC.

LONG TERM /WEDNESDAY THROUGH MONDAY/. The long term continues to be dominated by a large mid-level trough that is reinforced by shortwaves in the flow through the weekend and into next week.

Weak high pressure over the area on Wednesday may result in a few showers or thunderstorms though coverage should be rather isolated if they occur at all. The weak high shifts offshore into Wednesday night providing for an increasing southerly flow advecting moisture back into the area. An intensifying low pressure system to the north tightens the pressure gradient over the area ahead of the approaching cold front. Showers become likely much of the day Thursday with an isolated thunderstorm possible late in the day. Though there is some uncertainty in the timing of the frontal passage, showers looks to continue into Thursday night and early Friday.

A brisk NW flow behind the front on Friday gradually weakens into Saturday as a high pressure tries to build in from the southwest, but Friday and Saturday will be mostly, if not entirely, dry. High pressure quickly gets pushed offshore by Sunday as another frontal system brings another cold front into the area for late on Sunday. The strongest forcing appears to be toward the north of the area, but the GFS brings in a surge of moisture just ahead of the front resulting a significant difference in precipitation and rainfall amounts. Capped the PoPs at a chance for now. Thereafter, models diverge in the pattern but look to show a generally dry Monday and Tuesday.

AVIATION /03Z TUESDAY THROUGH SATURDAY/. Weak high pressure remains over the region into Tuesday. A cold front approaches from the north late in the day, and crosses in the evening.

MVFR in haze for northern terminals through the evening. Some haze aloft possible tomorrow afternoon, although HRRR model guidance not indicating vsby impacts to the surface.

Light and variable winds this evening, becoming W/NW less than 7 kt Tuesday morning. S/SE 8-12 kt afternoon seabreeze development expected at most terminals. Potential for scattered shra/tsra after 00z.

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

Light W/NW winds (less than 5 kt) for Tue morning push. S/SE seabreeze 8-12 kt for evening push. Potential for scattered shra/tsra btwn 01z and 05z

OUTLOOK FOR 00Z WEDNESDAY THROUGH SATURDAY. Tuesday night. Chance of brief MVFR/local IFR cond with any showers/isolated tstms. Wednesday and Wednesday night. VFR. Slight chance of a shower or tstm. Thursday and Thursday night. Chance of MVFR, local IFR, with a chance of showers and thunderstorms. Friday-Saturday. VFR.

Detailed information, including hourly TAF wind component forecasts, can be found at: https:/www.weather.gov/zny/n90

MARINE. A weak pressure gradient will be in place across the waters with conditions expected to remain below SCA thresholds through Wednesday night.

A strengthening southerly flow ahead of an approaching cold front will likely bring SCA conditions to the ocean waters late Thursday into Thursday night. Waves will slowly subside on Friday in a post-frontal NW flow, which may bring marginal SCA gusts during the afternoon. Elsewhere, conditions are forecast to remain below SCA criteria. Conditions drop below SCA conditions by Friday night.

HYDROLOGY. Layer PWATS reach almost 1.7 inches Tuesday night. Aside from the possibility of minor flooding with thunderstorms in low lying and poor drainage areas with locally higher amounts of rainfall Tuesday night, no hydrologic issues are expected through Tuesday night.

Looking ahead, no hydrologic impacts are expected Wednesday through early next week.

TIDES/COASTAL FLOODING. A moderate risk of rip current development is forecast for the ocean beaches for Tuesday, with a mix of 2 ft S and SE swells.
