The forecast for your own ground.
Big-league forecasting for hometown decisions. We put a weather station on your land, look after it, and use its readings to tune the forecast to your exact spot. When frost, wind, rain or heat is on the way, you get a heads-up by text or email in time to do something about it.
North block, tonight: low near 30 °F around 5:40 AM. Your line is 32 °F. Station now 41 °F, calm and clear.
The town forecast isn't your forecast.
Forecasts cover a big area, and your place doesn't act like the average of it. The low corner of a vineyard frosts first. A hilltop gets more wind. One field dries out a day before the one next to it.
Frost in the low spots
On clear, calm nights cold air rolls downhill and settles in the low ground. The town forecast can say 36° while your bottom rows drop below freezing.
A cold night after a pour
Fresh concrete needs a few mild nights to cure. One cold night the forecast never mentioned can mean redoing the job.
Rain the gauge missed
A storm can soak your fields while the gauge two miles away stays dry. Nobody finds out until the teams show up.
How it works
You never buy any equipment. Here's what happens from start to finish.
We put a station on your property
It belongs to us. We install it, stop by four times a year and fix anything that needs fixing.
We check it against an official station
Before we trust a single reading, each station sits next to an official weather station until we know they agree.
We tune the forecast to your spot
Our model takes the big public weather models and adjusts them using what your station actually measures.
You get a heads-up when it counts
By text or email, at the numbers you pick, with enough time to act.
We show you how we did
Every month you get a scorecard comparing our forecast with the National Weather Service, including the times we got it wrong.
You pick the numbers that matter.
Tell us what you need to know and when. A few examples:
Frost and freeze
Pick the temperature that worries you, like 32 °F or your bud-stage number, and we'll warn you hours ahead.
Spraying
A text when a calm, dry window opens up, say wind under 10 mph and no rain for 6 hours.
Planting
Know when the soil 2 inches down reaches 50 °F. This one needs the soil sensor.
Concrete pours
A warning if any night in the 3 days after a pour will drop below 40 °F.
Heat
Wet-bulb heat readings for practices and work crews, matched to your own heat policy.
Rain
When it's going to start and how much has fallen, like more than half an inch since midnight.
These are only examples; you set every number. We don't offer lightning alerts yet. We will once we've found a lightning data source we trust.
Who we work with
Anyone whose day depends on the weather at one particular place.
Growers and vineyards
When to run the frost fans, when to spray, when to plant, and when rain will hit at harvest.
Growers page (coming Feb 2027)Parks, turf and sports fields
Frost delays, rain-outs, when to mow, heat on game day, and wind for tents and events.
Parks page (coming Feb 2027)Schools and athletics
Heat at the practice field, rain before a game, and cold mornings for early buses.
Schools page (coming Feb 2027)Contractors and outdoor business
Safe nights for curing concrete, dry days for roofing and paving, and wind limits for lifts.
Contractors page (coming Feb 2027)We'll show you how we're doing.
A lot of weather services ask you to take their word for it. We'd rather show you. Every month you'll see how our forecast for your site compared with the National Weather Service, good months and bad. We won't claim to be more accurate until we have at least 90 days of public results to back it up.
The first scorecards come out in spring 2027.

Meet Jeremiah.
I grew up in Nebraska, where the sky pretty much runs your day. You learn early to watch the clouds, check the wind and keep an eye on the radar. That's where my love of weather started, and it never went away.
Today I work in operations control for a Part 135 air medical helicopter (HEMS) operator. When a call comes in, the weather is one of the first things we look at: cloud ceilings, visibility, wind and icing, not just at the base but at the scene and along the route. It's part of every go or no-go decision. After enough of those calls, you learn how much the weather at one exact place and time matters, and how often the general forecast misses it.
My background is in math and science, and I'm a licensed amateur radio operator, so I've always liked building things, testing them and finding out how they really work. FarmJAW Labs puts all of that together.
I'm married with two kids, and I'm building this business here in eastern Missouri for the people who work outside: growers, groundskeepers, coaches and contractors. You deserve a forecast built for your own ground, and an honest answer about how well it's doing.
Jeremiah Williamson, founder
Let's walk your ground.
It takes about half an hour. We'll walk the property with you, talk about which weather calls cost you money, and tell you straight whether a station makes sense. It's free, and there's no pressure.

Paying
The setup fee is due when you sign. Monthly billing starts once your station is up and running, and never before it passes calibration. We set you up on automatic bank draft, or you can pay by card. Schools and public bodies can use a purchase order, and we'll invoice with 15 days to pay.

Lightning alerts and the school safety option. We'll add them once we've found a lightning data source we trust. Heat (wet-bulb) alerts are available now.
Prices exclude any tax that may later apply by law.
Questions we hear a lot
Don't see yours? Email us at info@farmjawlabs.com and we'll answer it.
What do I get?
We put a weather station on your property and take care of it, with four visits a year. You get a forecast for your exact spot, tuned using what that station measures, plus text and email alerts at the numbers you pick. Every month you also get a scorecard showing how our forecast stacked up against the National Weather Service.
Do I have to buy the weather station?
No. We own the station and handle all the upkeep. You never buy or fix any equipment.
Why not just use a free weather app or the National Weather Service?
You should keep using them. Those forecasts cover a whole area. Ours is tuned to your piece of ground and warns you at the numbers you care about. We also put our results next to the National Weather Service every month, so you can decide for yourself if we're worth it.
How accurate is it?
Honestly, we're new, so we can't tell you yet. Our first stations are being tested right now. Once they're working on real sites we'll post every monthly score, the misses too. We won't make any claims about accuracy until those scores have been public for at least 90 days.
What does "calibrated" mean?
Before we use a station, we set it up right next to an official weather station and make sure the two agree within set limits. Each station that passes gets a certificate. You don't get billed monthly until yours passes. If it hasn't passed by the date we agreed on, you can cancel and get your setup fee back.
How do alerts reach me?
By text, email or both, sent to whoever you choose. You decide what sets them off, like a frost temperature, a wind limit for spraying, a soil temperature for planting, or a cold night after a pour. Texts come from "FarmJAW Labs Alerts", and you can reply STOP any time to turn them off.
What is a decision pack?
It's a group of alerts built around one kind of decision, like frost protection, spraying, planting, concrete pours, heat or rain. T1 comes with one pack. T2 and T3 come with every pack that fits your site.
What happens during the free site visit?
It takes about half an hour. We'll ask what kind of weather gives you the most trouble, walk the property looking for open ground and low spots, and check the cell signal and how we'd get to the station. Then we'll tell you honestly whether it's worth it for you. There's no obligation.
What does the station need on my property?
Just a small pole in an open spot, away from buildings and trees, that we can get to four times a year. It sends its readings over the cell network, and we check the signal when we visit.
Who owns the data?
We own the station and its data. As long as you're a client, you can use your readings however you like and download them any time. We also use station data to make forecasts better for everyone. Any scorecard we publish leaves out your name and exact location unless you tell us in writing that it's OK.
What if I want to leave?
Agreements run 12 months. When yours is up, you can renew or walk away. If you leave, we'll send you your readings and come take the station down.
Is this an official forecast or warning?
No. We help you make decisions for your site, but we're not an official source. Official watches and warnings come from the National Weather Service, and you should always follow them.
Do you offer lightning alerts?
Not yet. We'll add lightning alerts once we've found a lightning data source we trust. Heat (wet-bulb) alerts are available now.
Where do you work?
We're starting in eastern Missouri, around St. Charles County. If you're farther out, ask anyway. We group stations by area so the visits make sense.
Can a school or public body pay by purchase order?
Yes. Send us a purchase order and we'll invoice you, with 15 days to pay. Schools, nonprofits and family farms also get 10% off the monthly price.
Does the camera record people?
It only takes still pictures, with no sound. We keep the pictures for 30 days at most, unless one is needed because something happened.
What does it mean to be a founding client?
Our first five clients get 25% off the monthly price for the first year and see every score as soon as it's out. In return, we ask for an honest written review after six months, permission to share your scorecard without your name or exact location, and up to three short calls a year with people thinking about signing up.
