The National Blend of Models

NOAA NBM v5.0 · run of Oct 4, 1:00 PM CDT

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 Rhinelander (RHI) · 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 19, 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.

The sun is down, so each rating says which span it is for: tomorrow’s daylight, tonight, or the next 24 hours.

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.

Drone flying

NWS hourly forecast, SWPC Kp, FAA TFRs and 14 CFR Part 107

This hour: no-fly (gusts near or over your limit, wind at 400 ft near or over your limit, civil twilight: lighting required (107.29)). Next good stretch: Mon 7 AM to 6 PM, 11 hours.

Today: civil twilight for Part 107 6:28 AM to sunrise 6:58 AM, and sunset 6:30 PM to 7:00 PM. Anti-collision lighting is required in those minutes and at night.

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 Green Bay, WI · issued Oct 4, 6:05 PM CDT

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.

KEY Messages

A Frost Advisory is in effect late tonight into early Monday morning for north-central and far northeast Wisconsin, where low temperatures will drop into the lower to middle 30s.

Breezy southwest winds gusting 25 to 35 mph are expected Tuesday afternoon.

Patchy frost will be possible again over far northern Wisconsin on Thursday night and Friday night with low temperatures in the mid 30s.

Discussion

1133 AM CDT Sun Oct 4 2026

The latest RAP analysis and radar and satellite imagery show a cold front moving over Lower Michigan this afternoon, while surface high pressure builds in from the central Plains. Behind the front, cold advection and Lake Superior moisture fluxes are keeping strato-cumulus clouds scattered to broken over north- central Wisconsin, though these clouds will mix out later today. High pressure over the central Plains will migrate into the Great Lakes tonight, while a Pacific cold front will approach the region by Tuesday.

Frost And Near-Freezing Temperatures Tonight: As high pressure moves into the region late tonight, clear skies and precipitable water values at 50 to 60 percent of normal will create decent radiational cooling conditions. Winds remain the primary uncertainty, as statistical guidance suggests a light 3 to 4 knot breeze lingering overnight before decoupling toward daybreak. This slight breeze may keep temperatures from dropping as low as blended model guidance indicates, keeping confidence too low for a Freeze Warning. A Frost Advisory continues for north- central Wisconsin, with a 30 to 50 percent chance of temperatures falling below 33 degrees across northern Forest and Florence counties.

On Thursday and Friday nights, NBM percentiles also show a 30 to 50 percent probability of low temperatures falling into the mid-30s across the Northwoods.

Strong Wind Gusts On Tuesday: Southerly return flow strengthens on Tuesday as high pressure slides east and a Pacific cold front approaches the Upper Midwest. Warm advection will push daytime maximum temperatures into the upper 60s to lower 70s across inland central and northern Wisconsin. Tightening pressure gradients will produce gusty south- southwest winds, with NBM guidance showing a 60 to 80 percent probability of wind gusts exceeding 30 mph Tuesday afternoon. Moisture transport remains limited, keeping precipitation probabilities below 10 percent ahead of the frontal boundary.

Outlook for Hazardous Marine Conditions Through Tuesday Night: Breezy northwest winds of 10 to 20 knots and waves of 2 to 4 feet across northern Lake Michigan nearshore waters and Green Bay will continue to gradually subside by late afternoon. Surface high pressure centered over the region will then maintain quiet marine conditions tonight through Monday, with winds under 15 knots backing west to southwest Monday night and wave heights remaining 2 feet or less.

Hazardous marine conditions are expected to return Tuesday into Tuesday night as an advancing Pacific cold front tighten the regional pressure gradient. Southerly to south-southwesterly warm advection winds will ramp up significantly Tuesday morning to 15 to 25 knots, with gusts reaching 25 to 30+ knots across nearshore zones and potential for marginal gales over open Lake Michigan waters. These strong onshore winds will build waves to 5 to 9 feet along the Lake Michigan shoreline and 3 to 5 feet on Green Bay. Confidence is high that a Small Craft Advisory will be required for all Green Bay and Lake Michigan nearshore zones Tuesday afternoon through Tuesday night before winds shift westerly and subside behind the cold front Wednesday morning.

Aviation

557 PM CDT Sun Oct 4 2026

for 00Z TAF Issuance

VFR conditions will prevail through Monday afternoon. A deck of clouds around 8,000 feet will move across northern WI this evening before turn clear again overnight. Otherwise, northwest winds should drop off quickly around sunset to 5 to 10 knots, then continue around 5 knots overnight. Winds should back to the south/southwest late Monday afternoon. The exception will be at KMTW where winds should turn to the southeast around 20z. The next chance of rain across northern WI will be Monday evening.

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.
