Area Forecast Discussion National Weather Service New York NY 333 PM EDT Tue Oct 19 2021

SYNOPSIS. High pressure remains over the region through Wednesday night. A cold front will approach on Thursday and move across on Friday. Low pressure may pass southeast of Long Island on Saturday while an upper level disturbance moves across from the west. Another weak cold front moves across the area Sunday into Monday, followed by high pressure.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. High pressure continues to build into the region from the west tonight. A relatively light westerly wind flow is expected, and probably becomes light enough in some outlying areas for some radiational cooling. Have gone below NBM guidance for low temperatures in most areas, but more so for the areas that experienced stronger radiational cooling last night. Lows 55-60 in the city, and upper 40s to mid 50s for most other locations.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/. Deep-layered ridging for Wednesday with the ridge axis finally arriving here Wednesday night. Dry with little in the way of cloud cover for most of the period, although it could become mostly cloudy at times during the night as models show 700-600mb moisture shifting through the area possibly along with some cirrus.

Based on forecast 900mb temperatures and a westerly surface flow, expecting high temperatures in the mid 70s for most of the area. This could break records for BDR and ISP. See the climate section below for current records. Not as chilly at night this time around with a milder air mass and probably more cloud cover.

LONG TERM /THURSDAY THROUGH TUESDAY/. Long term period starts off with southwest flow and warm air advection continuing on Thursday. It will be dry with temperatures in the 70s across the entire CWA. The warmest temperatures will be across the Metro NJ area where highs will be in the upper 70s.

A cold front and upper level shortwave approach Thursday night and move across the area early Friday morning. The 12z forecast guidance is hinting that any precipitation associated with the front/shortwave will gradually dissipate as it move across our area, with the better dynamics remaining north of the region. Will carry just some slight chance POPs across the northern interior sections during this time period.

After that, a northern stream shortwave trough rounding the base of a developing longwave trough/closed low over eastern Canada should lead to showers on Saturday. This may also aid in offshore cyclogenesis with potential for a steadier rain mainly across Long Island Fri night into Sat. This will need to be monitored, as the development of the low may form far enough offshore that most of the weekend could be dry. With some uncertainty, will stick close to the NBM and keep chance POPs in the forecast.

Sunday looks mainly dry as sfc Canadian high pressure builds toward the area from the NW, but can't rule out an afternoon shower or two with another potent shortwave trough moving across. Another weak cold front is expected to move across the area late this weekend into early next week.

Temperatures will be above normal Thursday and Friday, then fall back to near normal for the remainder of the long term period.

AVIATION /20Z TUESDAY THROUGH SUNDAY/. VFR as high pressure slowly builds from the west.

High confidence in W-WNW winds 10-15G20-25kt, highest at the NYC metros. Gusts may become occasional at times. Only gradually diminishing at best this evening. W winds near 10kts late tonight. Gusts up to 20kts are expected tomorrow afternoon as well.

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

Gusts may be occasional this afternoon into this evening. Timing of gusts tomorrow may be off by 1 or 2 hours.

OUTLOOK FOR 18Z WEDNESDAY THROUGH SUNDAY. Wednesday. VFR. W winds G15-20kt. Wednesday night and Thursday. VFR. S winds G20kt late afternoon NYC metro/coastal terminals. Thursday night. Chance of showers with accompanying MVFR cond mainly at KSWF, otherwise mainly VFR. S winds G20kt in the evening NYC metro/coastal terminals. Friday. VFR. Saturday. Mainly VFR. MVFR or lower possible in showers Sunday. VFR

MARINE. SCA continues on all water this evening with a westerly flow. Have made the end time of the advisory at midnight for Western LI Sound and NY Harbor, and have extended the SCA through 18z Weds on the ocean as gusts to 25 kt continue. The SCA ends late tonight for the rest of the waters. Sub-advisory conditions then follow for the remainder of Wednesday into Wednesday night with a weaker pressure gradient.

Southwest flow increases on Thursday with small craft conditions developing, mainly on the ocean, Thursday night. Elevated ocean seas should last into Fri morning on all the ocean zones, then gradually diminish, with the eastern ocean zones lingering into Fri evening. Sub-SCA conditions are expected this weekend into the first part of next week.

HYDROLOGY. No hydrologic impacts are expected at this time.
