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 pollenNone 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.

KEY Messages
Updated at 125 PM CDT Sun Sep 27 2026
Hot and humid conditions continue through midweek. Heat indices of 110+ degrees on Tuesday and Wednesday afternoons.
A wetter pattern is looking more likely Thursday into the weekend, with widespread 60-80% rain chances.
There is a Marginal to Slight (levels 1 and 2 out of 4) risk of excessive rainfall later this week.
Discussion
125 PM CDT Sun Sep 27 2026
September will close out hot and mostly dry as ridging in the mid- upper levels remains dominant over deep South Texas. An isolated shower or thunderstorm along the sea breeze cannot be ruled out each afternoon into Tuesday. For the latter half of the week into the weekend, things get more interesting.
A trough over the desert southwest will ingest tropical moisture from the Pacific as it digs into West Texas early this week, bringing along with it a cold front. Midweek, the front is anticipated to stall over central Texas, which pulling Gulf moisture into the region. PWAT values in the latter half of the week could range from 2.3-2.6", nearing climatological maximum values for early October. Mid-level weakness will provide instability to support an increased chance of showers and thunderstorms across the region. Model guidance has continued to suggest heavy rainfall in Texas in the latter half of this week. However, being over 3 days out from the onset of any expected impacts over deep S TX, there remains uncertainty on the timing and axis of the heaviest rainfall. Latest guidance suggests this axis of rainfall will be heaviest to the north of deep S TX, but the forecast will continue to be monitored.
For deep S TX, widespread showers could come as early as late Wednesday, but more likely Thursday or Friday, with moderate to high PoPs continuing into the weekend. This will hopefully bring very welcome rain we've been missing, but training or heavy showers/storms can lead to flooding in low lying, poor drainage, and urban areas. The Weather Prediction Center has placed the region in a Marginal Risk (level 1 of 4) Wednesday, and a Slight Risk (2 of 4) Thursday of excessive rainfall leading to flash flooding.
Hot temperatures with heat indices in the triple digits are expected to continue into midweek, increasing as moisture builds ahead of the front. SPSs are possible Tuesday and Wednesday, and apparent temperatures above 111 degF are possible for brief periods. Increased cloud cover will limit temperatures, but it will still be warm and humid with highs later this week in the 90s.
Local beaches remain pleasant early this week, but will degrade as the front approaches. An increased risk of life threatening rip currents is likely, and increased wave heights may lead to concerns for minor coastal flooding.
Aviation
1215 PM CDT Sun Sep 27 2026
(18Z TAFS)
VFR conditions prevail. East-southeasterly winds this afternoon diminish overnight to light and variable, primarily out of the east. There is a low (less than 30%) chance of MVFR ceilings at HRL around sunrise Monday.
Marine
125 PM CDT Sun Sep 27 2026
Gentle to moderate south-southeasterly flow with slight seas prevail through Tuesday morning. An increasing pressure gradient will degrade conditions by midweek, with Small Craft Advisory conditions possible as early as Tuesday night with seas building to 4-7 ft. Low rain chances (20% or less) will continue through Monday, increasing Tuesday onwards. Rain chances increase to low-moderate (30%) through Wednesday, further increasing to moderate-high (60-80%) Thursday through the remainder of the period. Under any thunderstorms, expect locally higher winds and seas.

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.
