Site weather for eastern Missouri

The forecast for your own ground.

We install, calibrate and maintain a weather station on your property, correct the forecast to it, and alert you at the numbers that cost you money: frost, spray windows, soil temperature, pours, heat and rain.

Our stations are in calibration testing now. Founding-client installs are being scheduled for spring 2027.

Why it matters

Regional forecasts miss your field.

A forecast covers a whole area. Your ground has its own weather: low spots that freeze first, hilltops that catch the wind, fields that dry out sooner.

A vineyard's low spot

can freeze while the town forecast says 36 °F. Cold air drains downhill on calm, clear nights and pools where you can't see it coming.

A concrete pour

can be ruined by a cold night the forecast never mentioned, in the three days when curing matters most.

A ball field

can be unplayable after rain that fell two miles from the nearest gauge, and nobody knows until the coaches arrive.

How it works

Five steps. No hardware to buy.

  1. A station on your site

    We own it, install it and visit four times a year to keep it right.

  2. Calibrated first

    Every station is checked side by side against an official weather station before we trust a reading.

  3. Your forecast, corrected

    The FarmJAW North American Model corrects the major public models to what your station measures.

  4. Alerts at your numbers

    Text and email, at the thresholds you choose, with enough warning to act.

  5. Scored in public

    Every month you see how we did against the National Weather Service, misses included.

Alerts at your numbers

You set the line. We tell you before it's crossed.

Frost and freeze

Low spot below 32 °F, or your bud-stage line, with hours of warning.

Spray windows

Wind under 10 mph and no rain for 6 h after you spray.

Planting soil

Soil at 2 in reaching 50 °F. Soil sensor add-on.

Pours and curing

Any night below 40 °F in the 72 hours after a pour.

Heat for crews and athletes

Wet-bulb heat levels at your practice or work-rest policy lines.

Rain windows

Rain timing and totals, for example more than 0.5 in since midnight.

Examples only. You choose every threshold. Lightning alerts are not offered yet; they will be once a lightning data source is verified.

We keep score in public

Every month, against the National Weather Service. Misses included.

Most forecast services ask you to trust them. We publish how our forecasts did at each site, next to the official forecast for the same place and time. We make no accuracy claims until scores have been public for 90 days.

First scorecards: spring 2027.
