Built locally for our region

Weather is more useful when it is measured closer to home.

SEMO Weather Network connects privately owned weather stations across Southeast Missouri and neighboring Southern Illinois. It turns many neighborhood observations into one easy local view—while every station keeps its own name and identity.

How it works

From a backyard station to your screen.

The network does the technical work in the background so visitors can simply see what is happening nearby.

A station measures

A privately owned station records temperature, humidity, wind, rain, pressure, and any other readings its equipment supports.

The feed connects

Compatible services send current readings to the network. Ecowitt, Davis WeatherLink, Ambient Weather, Weather Display, and compatible JSON feeds are supported.

Freshness is checked

Every report is time-checked. A station that stops updating is marked stale and left out of combined county calculations until it reports again.

The region comes together

Readings appear on the station's county page and the regional map, making nearby conditions easy to compare without hiding the station behind the network.

What you can see

One network, several useful views.

A weather station tells you what is happening at one point. The network gives that observation context by placing it beside other stations across the county and region.

At home

Neighborhood readings

See the latest conditions from the station closest to the places you care about, including when that observation was recorded.

Across town

County pages

Compare active stations, scan county-wide highs and lows, and switch map markers between temperature, humidity, wind, gusts, and rain.

Across SEMO

Regional map

Move beyond county lines and see how conditions change across all 20 participating county areas.

When it matters

Official alerts

Active National Weather Service alerts are displayed separately from community observations, with a dedicated page for the full warning details.

Clear about the data

Local observations and official weather information have different jobs.

Community stations

These instruments show hyperlocal conditions that an airport or distant official station may not capture. Their readings are useful, but they are unofficial.

National Weather Service

Forecasts, watches, warnings, and safety instructions come from official sources. Always follow National Weather Service guidance and local authorities during hazardous weather.

Visible freshness

The network shows whether a station is reporting and protects county summaries from outdated readings. Missing data is shown as missing—not guessed or filled in.

For station owners

Your station stays yours.

You choose its public name, general area, equipment description, map location, and whether to link to its own website. Connection credentials and contact details remain private, and visitors see a neighborhood or general area rather than a street address.

Made in Southeast Missouri

A local project built for local weather.

SEMO Weather Network is an independent community project designed and maintained locally by SEMO Web Co. The goal is simple: make real neighborhood weather easier to find, understand, and share across the region.
