The National Blend of Models

NOAA NBM v5.0 · run of Sep 30, 7:00 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 Fond Du Lac (FLD) · 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 Fri Oct 16, 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.

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 Milwaukee/Sullivan, WI · issued Sep 30, 10:57 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

Moderate to heavy rain will spread into southern Wisconsin mostly after 3 AM CDT Thursday and last through the morning. on average, 1.5 to 2.25 inches of rain is forecast through Thursday, but much less toward central WI. Urban and small stream flooding and isolated flash flooding will be possible where locally higher rain amounts occur. Otherwise, rises in rivers and low lying areas are expected.

Short Term

Issued 1057 PM CDT Wed Sep 30 2026

Tonight through Thursday night:

The forecast for widespread mdt to heavy rainfall remains on track for late tnt-Thu AM. A wave of low pressure over central KS will track to ern IA by 12Z Thu, while a shortwave trough over NE into nw IA approaches srn WI during this time. The nose of a swly low level jet of 40-45 kt will set up over far srn WI. Deep, sloping frontogenesis will develop across the region as the low and aforementioned features shift across srn WI into lower MI on Thu. The strong lift will occur within a saturated troposphere and PWATs around 2 inches. Thus high precipitation efficiency is expected. The mean flow will be fairly fast, but several hours of mdt to heavy rain will still occur for most locations. Rainfall amounts of 1.5-2.25 inches are forecast with locally more. Urban and small stream flooding and isolated flash flooding will be possible where those locally higher amounts occur. There is some confidence based on CAMs that a band of the heaviest rain will stretch from far sw WI into the Madison area. Rainfall amounts toward central WI will be much less. The widespread rain will continue over se WI for the afternoon followed by cooling and drying from the north afterward. Skies will gradually clear Thu nt on nly winds and cold and dry air advection. Temps will remain in the 60s tnt and tomorrow then fall into the middle 40s to lower 50s by sunrise Friday.

Gehring

Long Term

Issued 1057 PM CDT Wed Sep 30 2026

Friday through Wednesday:

The models have fairly good agreement for the overall pattern this weekend into next week. Nly winds and weakening cold advection will prevail on Fri followed by high pressure around 1027 mb for Fri nt. After a relatively cool day in the lower 60s, low temps will fall into the middle 30s to lower 40s inland from the lake. Patchy frost will be possible around sunrise Sat north of Madison.

A west to northwesterly flow aloft will prevail for the weekend into the middle of next week. A shortwave trough and sfc low will track across the Canadian border over the Great Plains on Sat, with the low to deepen and track into central Ontario for Sat nt. Sly winds and warm advection will return to srn WI followed by a dry cold front Sun AM. High temps will warm through the 60s for the weekend.

A surface ridge will pass on Mon followed by another low across central Canada bringing sly winds to srn WI on Tue. Relatively cool temps on Mon will warm a bit for Tue, followed by another cold front and upper trough passage on Wed. There is uncertainty on whether this front will be a dry passage, but the forecast is dry at this time.

Gehring

Aviation

Issued 1057 PM CDT Wed Sep 30 2026

Cigs well below 1 kft will develop this evening and last through Thu AM, then lingering into the afternoon over SE WI. Vsbys of 2-4SM via BR and drizzle will prevail this evening then dropping to 1-2SM via BR and widespread rainfall during the overnight and much of Thu AM. Local 1/2SM FG will be possible during this time. The widespread rain will continue over SE WI during the afternoon with low Cigs and vsbys continuing. Cigs and Vsbys will then rise to MVFR then VFR from nw to se across srn WI from late afternoon into the evening.

Gehring

Marine

Issued 1057 PM CDT Wed Sep 30 2026

Modest southwest winds will continue tonight then shift westerly ahead of a cold front by the middle of Thursday. Expect winds to then shift northwest with the frontal passage Thursday afternoon. Modest to breezy northerly winds are then forecast Thursday night and Friday. Strong high pressure around 30.4 inches will then overspread the Great Lakes Friday night. This should bring lighter winds to the lake Friday night into Saturday.

A fast-moving low pressure system around 29.8 inches should move across or north of Lake Superior Saturday night, with high pressure around 30.4 inches moving southeast into the region by early next week. South to southwest winds Saturday night should veer northwest to north Sunday into Monday across Lake Michigan.

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.
