Area Forecast Discussion National Weather Service New York NY 240 PM EDT Sat Apr 18 2026
WHAT HAS CHANGED
No significant changes.
KEY MESSAGES
1) Mainly dry conditions tonight with low clouds and possible fog, especially near the coast.
2) Minor flood benchmarks forecast to be reached or exceeded at many coastal locations for tonight's high tide cycles.
3) Showers on Sunday with a cold front transition to much colder air early next week.
4) A warming trend begins Wednesday leading to above normal temperatures to end the week.
DISCUSSION
KEY MESSAGE 1
A frontal system approaches tonight. Much of the night will be dry with the main concern revolving around potential fog, especially near the coast, due to onshore flow and warmer air above the surface. Confidence in any dense fog is low at this time, but will have to monitor trends this evening. Forecast soundings indicate some mixing in the lowest levels, which may prevent visibilities from dropping to a quarter mile or less.
Any showers should hold off till very late and more towards day break well NW of the NYC metro.
KEY MESSAGE 2
The combination of the recent new moon and an E/SE flow will produce water levels at or just above minor coastal flood benchmarks around the time of high tide tonight. Most tidal locations need water levels of 0.5 to 1 1/2 ft above normal to make this happen. Latest surge guidance is in decent agreement for this to happen, however, there was a slight downward adjustment in some locations. There is a chance much of the advisory area will struggle to get too much above the minor level. The best chance for this to happen will be across the back bays of southern Nassau, and coastal Fairfield.
However, it seemed prudent to air on the safe side at this time and keep the hazards in place.
Water levels are forecast to gradually subside Sunday into Monday, but could touch the minor benchmark in southern Nassau and SW Fairfield on Sunday.
KEY MESSAGE 3
The aforementioned cold front will move across the region Sunday morning. Some showers are possible ahead of the front, but much of the activity will follow the front. Most of the support for showers on Sunday comes from forcing ahead of the mid and upper level trough and approaching strong upper level jet. While a brief downpour cannot be ruled out, the majority of the showers will be light to moderate with no concerns for any hydrologic impacts. There is little to no CAPE, so have left mention of thunder out of the forecast. Total rainfall remains on the light side with amounts around two to four tenths, highest inland. The shower activity should quickly end from west to east mid to late afternoon.
High temperature on Sunday will occur early in the day.
Temperatures will fall behind the front, with 40s likely across the area by mid to late afternoon. Cold advection will continue Sunday night with temperatures bottoming out in the mid to upper 30s for most spots and low 40s in the NYC metro. There should be enough of a breeze and dewpoint depressions to prevent frost formation where the growing season has begun.
Sprawling high pressure gradually builds towards the area early next week. Temperatures will end up 10-15 degrees below normal on Monday. Cyclonic flow and steep lapse rates with a cold pool aloft should lead to the development of stratocu Monday afternoon. Continue to carry slight chance PoPs (~20%), with potential for a few brief pop up showers. A few could even contain ice pellets across the northern interior.
The coldest temperatures early next week appear likely Monday night with clear skies and light winds helping to efficiently cool the BL. A widespread freeze appears likely outside the urban NYC metro, with lows ranging from the mid 20s across the interior to mid 30s in the city, or about 10 to 15 degrees below normal. A freeze watch will eventually be needed for the interior and potentially portions of the coast. Temperatures in the NYC metro should remain in the mid to upper 30s.
Temperatures will remain below normal on Tuesday with high temperatures in the low to mid 50s. The high pressure shifts offshore Tuesday night. This will set the stage for a weak return flow and a milder night compared to Monday night.
KEY MESSAGE 4
A warm front lifts north of the area on Wednesday and will be quickly followed by a weak cold front late in the day. An isolated shower is possible. The main story will be temperatures beginning to warm closer to normal on Wednesday. Despite the cold front passage, warmer air is expected on Thursday with a NW downslope flow with highs in the 60s for most places and lower 70s in the NYC/NE NJ metro. Similar temperatures are possible to end the week along with dry conditions.
AVIATION /18Z SATURDAY THROUGH THURSDAY/
High pressure will remain along the coast tonight. A cold front will approach late tonight and pass through Sunday morning.
MVFR cigs in place just south/east of the NYC metros should spread into the metro airspace after 22-23Z. Conds should then quickly lower to IFR this evening, then LIFR especially after midnight, from KJFK/KLGA/KHPN east. Less certain if KEWR/KTEB will see LIFR conditions but if they were to occur they would be late tonight from about 08Z-11Z.
Cold fropa takes place in the morning accompanied and followed by showers, with winds shifting NW 15-20G25 at the NYC metros and 10- 15G20kt elsewhere. Improvement in flight category will be slow to take place due to the post-frontal showers, but expect MVFR cond to return to the NYC metros by 14Z-15Z and to all terminals by 18Z.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
High confidence in winds. Medium confidence in timing and extent of lower cigs/vsby tonight. Amendments likely.
OUTLOOK FOR 18Z SUNDAY THROUGH THURSDAY
Late Sunday afternoon: Flight cat improving to VFR. NW winds 15-20G25kt at the NYC metros and 10-15G20kt elsewhere.
Monday: Mainly VFR. Slight chance of showers. NW winds G20kt.
Tuesday: VFR.
Wednesday: Mainly VFR. Slight chance of showers.
Thursday: VFR.

MARINE
Fog is possible this evening into tonight. However, confidence in dense fog remains low at this time. Otherwise, conditions will remain below SCA levels through tonight.
A cold front crosses the waters early Sunday. NW flow increases behind the front, leading to marginal SCA wind gusts on the near shore ocean waters, LI Sound, LI Bays, and NY Harbor. Nearshore ocean seas will likely remain below 5 ft. Winds and seas subside Sunday night with conditions remaining below SCA levels through the middle of next week.
