The National Blend of Models

NOAA NBM v5.0 · run of Oct 1, 7:00 AM 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 Sparta/Mccoy Aaf (CMY) · 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 La Crosse, WI · issued Oct 1, 5:53 AM 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

Ongoing heavy rain locally affects parts of northeast Iowa into far southwest Wisconsin with 2 to 2.5 inches of precipitation expected through today.

Cooling trend into new week increases frost/freeze concerns mainly Monday morning.

Discussion

120 AM CDT Thu Oct 1 2026

Today: Widespread Rainfall

A widespread area of moderate rainfall is slowly making its way north and east out of the Central Plains and into the Mid/Upper Mississippi River Valley. Heavier rainfall is just making it into Northeast Iowa and Southwest Wisconsin late overnight with the heaviest of the precipitation still back near the core of the low around Omaha, NE. That will trek NE through the remainder of the overnight hours and through the morning. This will be co-located with precipitable water values in the 1.6-1.9 inch range. The latest 01.00 HREF 6 hour precipitation LPMM shows a few blotches of 3.5-4 inches across far southern portions of Fayette, Clayton, and Grant Counties. While there is still a 15-30% chance for 3-4 inches in those aforementioned locations, more likely totals will be closer to 2-2.5 inches.

There will be a fairly sharp northern cutoff in QPF with locations outside of Northeast Iowa and Southwest Wisconsin likely not seeing more than 0.5 inches of rain by 12Z Friday, evident in a sharp cutoff of precipitable water values in 01.03 RAP analysis. PWATs drop off to less than 1.5 inches as one moves north of the IA/MN state line with moisture transport more prominent south of our area across Southern and Central Iowa. This moisture transport will continue into northeastern Illinois and southern Wisconsin where the axis of heavy rain will extend by morning. The heaviest rain should push off to the east by mid morning as a cold front starts to move in from the northwest. Rain chances will gradually end through the day with most locations dry by 00Z Friday.

Thursday Night - Friday Night: Dry and Slightly Cooler

High pressure is expected to build in behind the aforementioned cold front. High temperatures Friday will be slightly cooler in the upper 50s to low 60s with lows Thursday night in the upper 30s to upper 40s. Friday night lows will drop into the mid 30s to mid 40s and some places across central and north central Wisconsin could see their first areas of frost this fall.

Saturday - Mid Next Week: Low Rain Chances Sat PM, Dry to Follow

Another cold front is expected to move southeast through the region Saturday afternoon/evening. Low potential for weak scattered showers across portions of Southeast Minnesota and West Central Wisconsin Saturday evening accompanying frontal passage but overall QPF amounts remain low, from 0.01-0.02 inches. This would be a quick hitter and likely wouldn't even have much of an impact on temperatures as highs Saturday and Sunday will be comparable in the mid 60s. The only thing of note would be the potential for frost across portions of Central and North- Central Wisconsin Monday morning as low temperatures could fall into the mid-30s across that region. Otherwise, high pressure looks to keep conditions dry next week with high temperatures generally in the 60s to near 70 degrees.

Aviation · 12Z TAFs Through 12Z Friday

549 AM CDT Thu Oct 1 2026

Ongoing rainfall will continue through the early morning hours, exiting east of much of the local area within a couple hours of 01.12Z TAF issuance. Subsequent potential for a narrow band of MVFR ceilings through the later morning hours before VFR conditions and strengthening north winds through the daytime hours.

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.
