The National Blend of Models

NOAA NBM v5.0 · run of Sep 27, 2:00 AM EDT

NOAA’s weighted blend of every model it runs, to eleven days, with the chances the grid above does not carry. Where the local office’s grid reaches, its figure sits beneath the blend’s; where it does not, the blend stands alone.

The next 90 days

NOAA GHCN normals and records at East Hampton (JPX) · Climate Prediction Center outlooks

No forecast has skill day by day past about two weeks, and this page does not print one. Where the models stop, the calendar takes over: the 1991 to 2020 normal for each date, the record high and low ever set on it, and where the Climate Prediction Center leans warm, cool, wet or dry over the coming weeks, the month and the season. A site that shows a high for a date three months out is showing you this normal with a wobble.

The forecast reaches Mon Oct 12, from the NWS grid, then the National Blend, then the mean of the global models. Beyond it the lines are the calendar.

Health and activities

Rules of thumb over the next 24 hours of forecast, the warnings in force, the station’s report, air quality and pollen

None of these is a measurement. Each is a rating of the forecast ahead, and of what is happening at the point right now, against what the activity or the ailment is known to mind, and each names the figure that decided it. An ailment or a pest is rated as a risk, low to extreme; an activity, a chore or a journey as a condition, poor to ideal.

Each rating says which span it is for: the rest of today’s daylight, tonight, or the next 24 hours.

The last night runs past the end of the forecast and is rated on the hours it covers.

Dark is the sun 18 degrees below the horizon; where it never gets that low, 12 degrees, marked nautical. Clear is sky cover of 20% or less. A bright moon is one above the horizon with a quarter or more of its disc lit. Transparency in the table is estimated from surface humidity (70% and 85% mark fair and poor) and visibility, since the forecast carries no haze or high cloud moisture. Seeing and transparency by hour, where shown, are Environment and Climate Change Canada’s astronomy forecast (regional model; seeing from cloud, wind shear, turbulence near the ground and the surface temperature trend; transparency from the moisture through the whole air column), under the Open Government Licence - Canada. Dew is the air within 2 °C of its dew point. Excellent is four or more clear moonless hours with good transparency; good is three; fair is one, or two clear hours.

Golden hour is the sun between 6 degrees above the horizon and 4 degrees below it; blue hour is the sun between 4 and 6 degrees below. These are the definitions timeanddate.com and PhotoPills use. Directions are degrees clockwise from true north, where the sun’s upper edge and the moon’s center cross a flat horizon; hills and buildings change both. None means the sun does not reach that height on the day; all day means it stays inside the band.

Flight restrictions nearby

Reading the FAA’s temporary flight restrictions.

Flight restrictions on the map. TFRs are not the whole picture: controlled airspace around airports needs LAANC authorization. Check the FAA’s B4UFLY.

Wind at 400 ft is estimated from the 10 m forecast by the power law, with exponents for each Pasquill stability class (Irwin 1979, rural, as in EPA dispersion models; the class from wind, sun height and cloud, after Turner 1970); gusts keep the ground gust’s margin. Caution from three quarters of your limit; the default 24 mph is the wind resistance printed for common sub-250 g drones. 14 CFR 107.51: “The minimum flight visibility, as observed from the location of the control station must be no less than 3 statute miles” and at least “500 feet below the cloud”. 14 CFR 107.29: “No person may operate a small unmanned aircraft system during periods of civil twilight unless the small unmanned aircraft has lighted anti-collision lighting visible for at least 3 statute miles”; civil twilight is the 30 minutes before sunrise and after sunset, in Alaska the Air Almanac’s. Kp: SWPC’s scales say satellite navigation problems may occur at G3 (Kp 7) and navigation is “degraded for hours” at G4 (Kp 8); Kp 5 is the typical app warning. Typical limits, not rules: rain chance 30% caution and 60% no-fly, thunder 10% and 20%, below 0 °C caution and −10 °C no-fly, over 40 °C caution. Your drone’s manual and the airspace come first.

Spraying: sustained wind 3 to 10 mph, the range US extension services and most labels give; gusts no more than 15 mph (this page’s limit); delta T (air minus wet-bulb temperature) 2 to 8 °C preferred and 8 to 10 °C marginal, from GRDC guidance, with the wet bulb by Stull’s formula; no hour at a 30% chance of rain or 0.25 mm forecast during the rain-free time. Follow the product label, which overrides all of this. Field days: dry is no daytime hour at a 30% chance and under 1 mm all day, wet is 6 mm (0.25 in) or more; soil moisture is not in the forecast, so ground still wet from earlier rain is not accounted for. Hay drying marks a dry day with humidity down to 50% and a breeze of 5 mph or more.

Periods in bold fall within an hour of sunrise or sunset. The weather’s side is the fishing index

Major periods are two hours centered on the moon’s passage overhead and underfoot; minor periods are one hour centered on moonrise and moonset: the conventional durations of John Alden Knight’s solunar tables (1936). The rating is this site’s: one point to start, two more within a day and a half of a new or full moon (one more within three and a half days), and one more when a period falls within an hour of sunrise or sunset. The theory has mixed support in fisheries research; the times are exact astronomy.

The forecaster’s discussion

NWS New York, NY · issued Sep 27, 4:39 AM EDT

Written by the forecaster on duty for their own colleagues and for anyone who wants to know why the forecast says what it says. It is not edited for the public, so it uses the office’s shorthand; it is also the most honest thing any weather service publishes.

What Has Changed

Replaced high wind warning with a wind advisory across Long Island and SE CT.

KEY Messages

1) A nor'easter will continue to produce strong winds across the region this morning.

2) Bands of moderate to locally heavy rain persist through the rest of the weekend. Widespread minor urban, poor drainage, and small stream flooding likely, with only isolated instances of flash flooding possible.

3) Coastal flooding impacts are expected during times of high tide through Monday. Moderate to locally major inundation possible this morning.

4) High surf and dangerous rip current risk continue today.

Discussion

KEY Message 1

Low center was S of Long Island and E of the NJ coast as of 08Z and should continue moving westward toward NJ today while weakening, then stall near the NJ coast tonight, and drift slowly E on Mon, passing S of Long Island. With the parent upper low passing over the area expect bands of moderate to locally heavy rain and embedded tstms to still be possible.

Not seeing winds 58+ mph anywhere in the CWA though they might still be possible in immediate coastal areas with N-NE exposure. Given that limited impact replaced the high wind warning across Long Island and SE CT with a wind advisory. Advisory continues elsewhere through this morning for potential impacts from wind gusts 40-45 mph (just below official criteria) with trees still leafed out and wet ground.

KEY Message 2

Greatest potential for bands of moderate to heavy showers will be this afternoon and evening, with additional rainfall of 1-2 inches (locally higher across CT/Long Island) still possible. Latest HREF prob of an inch of rain in 3 hours as high as 50-60% across Long Island and the NYC metro area late today into this evening, with a slight (20%) chance of 2 inches in 3 hours across central Suffolk County late today. Still opted not to issue a flood watch, as flooding unlikely to be considerable and more likely in the minor nuisance category.

KEY Message 3

The current forecast is based on a blend of the previous forecast the the 00Z NYHOPS 50th percentile, ETSS/PETSS 50th percentile, and STOFS guidance. Surge models have over-performed so did not consider the higher percentiles of probabilistic guidance despite winds veering more NE this morning.

Coastal flood warnings will be allowed to continue for one more tide cycle as locally major flooding may still be possible along the back bays of S Nassau and SW Suffolk counties, with moderate flooding also expected in spots along Peconic Bays, the western Sound, and lower NY Harbor and Jamaica Bay, minor to locally moderate flooding in tidally impacted areas of NE NJ, and minor flooding along the Hudson River in the lower Hudson Valley.

As winds diminish the coastal flood threat will lessen, with widespread minor flooding expected during the high tide cycles tonight and Mon morning. Some spotty minor flooding may last into Tue and Wed with the morning high tide cycles on those days.

KEY Message 4

High risk of rip currents and high surf today along ocean shorelines, with surf heights up to 8-11 feet possible. Additional beach erosion likely with the high tide cycle this morning.

This will be the last issuance of routine surf zone products and high surf advisories for the 2026 season.

Aviation · 07Z Sunday Through Thursday

Low pressure approaches the coast this morning, bringing strong winds and periods of rain.

Mainly MVFR or lower thru the TAF period. Pockets of VFR remain possible, mainly for western and inland terminals. Cigs may fall to IFR at times tonight, briefly improve to MVFR by late Sunday morning, then decline to IFR Sunday evening.

N-NE winds 15-25 kt with gusts 30-45 kt expected through early morning. A few isolated gusts up to 50 kt possible. Winds veer to the E or ENE by early afternoon and begin to lighten into the evening, though gusts 20-30kt remain overnight into Monday morning as the wind shift back to the N/NNE

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

Cigs could bounce between MVFR and IFR overnight.

Occasional gusts upwards of 50 kt possible thru about 15Z.

Low chance of an isold embedded tstm, especially 08-13Z Sun.

Outlook For 06Z Monday Through Thursday

Sunday Night: IFR in -RA/BR. Winds gradually diminishing.

Monday: MVFR or lower. Winds generally blw 20kt with VRB direction thru the day.

Tuesday: Becoming VFR with light winds.

Wednesday: VFR with SW flow.

Thursday: VFR with W flow.

Letting storm warnings ride for most of the ocean waters til 12Z. Replacing storm warning with gale for Sandy Hook-Fire Island Inlet out 20 nm as winds at 44065 have been quite a bit short. Converting any storm warnings on the non ocean waters to gale warnings as well and running through 6 PM today for simplicity's sake even though gusts may come down below gale force by early afternoon.

SCA cond expected on all waters late this afternoon and tonight, then hazardous ocean seas may linger E of Fire Island Inlet from Mon into Mon night.

Forecast from the National Weather Service forecast grid at api.weather.gov, updated by the local office through the day; the written periods and hourly digest are the NWS’s own. Outlooks from the Storm Prediction Center, the Weather Prediction Center and the Climate Prediction Center via NOAA’s map services. Records and normals from NOAA’s Global Historical Climatology Network. Sun and moon computed here. Place names from GeoNames (CC BY 4.0).

What is here

Seven days
The high, the low, the chance and amount of rain and snow, the wind and the forecaster’s words for each day and night, from the National Weather Service grid for the exact cell your town sits in.
Hour by hour
Temperature, what it feels like, dew point, humidity, chance and amount of precipitation, wind and gusts, sky cover, the chance of thunder, pressure, visibility and ceiling, as a chart and as a table, with nights shaded.
Everything else on the grid
The office edits about sixty fields for every cell. The ones the mainstream forecast pages leave out are here as a daily table: HeatRisk, wet bulb globe temperature, lightning activity, mixing height, transport wind, the fire weather indices, and at the coast the waves and swell.
The discussion
The Area Forecast Discussion the forecaster wrote to explain the forecast, in their own words, with the specialist annexes folded away. Also the office’s hazardous weather outlook.
Beyond the week
The Storm Prediction Center’s severe weather category for each of the next eight days, the Weather Prediction Center’s rainfall forecast to day seven and its winter storm severity, and the Climate Prediction Center’s odds for days six to fourteen, all read at your coordinate.
Against the record
Each forecast day beside the same date at the nearest long-record station: the thirty-year normal and the record high and low with their years, so a forecast high that would break a record says so.
The next 90 days
The forecast as far as the grid, the National Blend and the global models reach, and the calendar after that: the normal and the record for every date, with the Climate Prediction Center’s lean for the weeks, the month and the season drawn over them. No made-up highs for a date three months out.

Common questions

Where does this forecast come from?

From the National Weather Service forecast grid published at api.weather.gov, the same grid the local forecast office edits through the day and the source of every forecast on weather.gov. The written periods, the hourly digest and the forecaster’s discussion are the NWS’s own products, shown as issued. Nothing here is a blend a website made.

How far ahead does it go?

The grid runs seven days ahead, hour by hour for the first days and in three to six hour steps after that. The National Blend of Models carries the days to eleven and the global models to sixteen. Beyond that the page carries the national centers’ outlooks, severe weather to day eight, rainfall to day seven, and the Climate Prediction Center’s odds for the coming weeks, month and season, over a ninety-day calendar of the normal and the record for each date. No forecast has skill day by day past about two weeks, and this page does not print one.

Why is this different from the app on my phone?

Most forecast apps show a blend of models chosen by the company that makes the app. This page shows the forecast the local National Weather Service office issues, edited by the forecasters who will also issue the warnings, and it shows all of it rather than the six numbers that fit on a phone. The discussion explains the reasoning, which no app carries.

What is a place’s address here?

Every town has its own page, such as /forecast/us/oklahoma/oklahoma-city/, and every day at a town has one too. A ZIP code typed into the search goes to the town it belongs to. Any coordinate at all can be looked up, and the page names the nearest town.
