Area Forecast Discussion National Weather Service New York NY 720 AM EDT Mon May 18 2026
WHAT HAS CHANGED
No significant changes, with hot weather expected thru Wed.
KEY MESSAGES
1) Summerlike temperatures through Wednesday
2) A cold front moves across Wednesday bringing showers and thunderstorms. Brief gusty winds and locally heavy rain possible.
3) Much cooler airmass expected Thursday into the holiday weekend.
4) Cold water safety concerns continue this week with good boating weather, and water temperatures still in the 50s.
DISCUSSION
KEY MESSAGE 1
No major changes to the hot fcst thru Wed. Kept with the previous trend of going a bit blw the NBM which is believed to be too warm. Went with a 50/50 blend of the MAV and NBM to accomplish this.
The shallow backdoor cold front looks to have little impact on temps today aside from ern areas and LI, where onshore flow may limit highs a bit. Otherwise the hot airmass continues to build in. Depending on where the numbers end up today, there is a chance some of the usually warmer spots may need a heat advy based on the two-day 95 degree criteria. In addition, temps could spike on Wed ahead of the front. Guidance often has a tough time getting hot enough invof a front, especially a few days out. Despite that bias, the MAV/NBM blend still has a high of 94 for KNYC on Wed.
KEY MESSAGE 2
It looks increasingly likely that a cold fropa will occur during the day on Wed. The actual timing will be critical. Low moisture but sufficient instability and no CIN should allow for tstms to develop invof the front assuming a daytime passage. The best upr support is to the north, but there will be falling heights nonetheless.
Primary severe threat based on the setup appears to be downburst winds with relatively high based storms attm. DCAPE in the NAM supports this with peak values around 1500J/kg modeled. There could be some hail as well with the dry air entrainment.
KEY MESSAGE 3
Mid level ridge suppressed for late week into the holiday weekend. At the surface, high pressure moves in from the Great Lakes Thursday but then moves northward into Northern New England and eventually the Canadian Maritimes Friday into the holiday weekend.
Max temperatures forecast decrease by near 15 to 20 degrees for Thursday compared to the previous day. Max temperatures are in the upper 60s to lower 70s Thursday.
Cooling trend continues Friday with high temperatures forecast mainly in the mid to upper 60s and then just low to mid 60s for most locations on Saturday.
Overall, the low level flow will become more easterly. Along with that aside from Thursday and Friday which are forecast to be mainly dry, there will be an increasing chance of showers heading into the holiday weekend with high pressure getting farther away and low pressure approaching from the south and west.
KEY MESSAGE 4
Cold water safety concerns this week as water temperatures remain in the 50s. The cold water temperatures can quickly cause hypothermia and physical incapacitation to anyone suddenly immersed in the water. Anyone going out on small boats, canoes or kayaks should plan accordingly and use extreme caution to avoid this threat.
AVIATION /12Z MONDAY THROUGH FRIDAY/
A weak backdoor cold front will make it about as far west as the Hudson River this morning before jumping back to the north as warm front late morning into early afternoon. Otherwise, high pressure will remain over the western Atlantic with a frontal system over the mid section of the country. This will keep us in a warm, southerly flow.
VFR through the TAF period.
Light E/SE winds develop this morning, gradually veering to a more southerly direction late morning into the afternoon, increasing to around 10kt with a some locations G15-18kt. KLGA is expected to be NE-ENE during the morning and early afternoon hours before veering to more southerly flow. KBDR also could hang on to an E wind into the afternoon. Winds diminish tonight to under 10 kt from the S/SW.
...NY Metro (KEWR/KLGA/KJFK/KTEB) TAF Uncertainty...
Gusts may be more occasional this afternoon.
Winds may also be more to the left of the current forecast. This will depend on how much the area can heat up to mix down a more S to SSW flow.
OUTLOOK FOR 12Z TUESDAY THROUGH FRIDAY
Tuesday: VFR. S/SW winds 10-15g20-25kt into eve. Isolated thunderstorm potential afternoon into early eve, mainly north of NYC terminals with brief MVFR or lower possible.
Wednesday: VFR, giving way to possible MVFR or lower with potential showers and thunderstorms. Showers likely afternoon into eve with a chance of thunderstorms. S/SW winds 10-15g20-25kt day into eve. Peak gusts to near 30 kt possible.
NW windshift in the evening.
Thursday-Friday: MVFR or lower possible with a chance of showers.
