Model-driven weather briefings that turn raw forecast data into go/no-go decisions, work schedules, and dollar-impact alerts. Built for the trades that lose thousands when the weather surprises them.

Two solid pour days, then a hard freeze moves in. Wednesday night lows hit 26°F — anything poured after Tuesday 2pm won't reach 500 PSI before temps drop.
Weather apps are built for picnics. Your decisions have five- and six-figure consequences. A wrong call on a pour, a roof, or a job site costs more before lunch than your weather app costs in a lifetime.
A concrete pour that freezes overnight is a full tearout. A roof crew caught in a storm is a safety incident. An outdoor event in a downpour is a lawsuit. These aren't inconveniences — they're five-figure losses.
You're scheduling pours, dispatching crews, and committing to timelines based on a 10-day forecast that doesn't know the difference between drizzle and a washout.
Your iPhone says "partly cloudy, 45°F." It doesn't say that's below the threshold for shingle adhesion, too cold for a pour without accelerants, or that wind gusts will exceed crane safety limits by 2pm.
One email. Under 500 words. Delivered Sunday evening so you walk into Monday with a plan.
HRRR model runs, NWS forecast discussions, active alerts, soil temps, humidity, wind at elevation — the stuff that actually matters for your operations, not a zip code average.
Our intelligence layer knows that 40°F and rain means something different to a concrete contractor than a roofer. It applies your industry's thresholds, safety limits, and cost exposure to every data point.
"Move Monday's pour to Wednesday. Blanket slabs by 6pm Thursday. Next window opens Saturday." Specific timing, specific actions, specific dollar risk if you ignore it.
Real weather data. Real recommendations. Written for your trade — not copy-pasted from Weather.com.
A concrete contractor gets pour windows and cure conditions. A roofer gets wind limits and seal temperatures. A GC gets multi-trade coordination. Same weather data — completely different briefing.
We analyze at the mesoscale level — the 10-to-200 mile range where terrain, elevation, and local patterns create the weather that actually hits your job site. Powered by the same HRRR model data used by NWS forecasters.
We don't just say "rain Tuesday." We say "a pour that gets rained on before initial set is a $12,000 problem — move it to Wednesday." Every action item is tied to the cost of getting it wrong.
Under 500 words. No dashboards. No 10-page PDFs. One email you scan Sunday evening and walk into Monday with your week planned.
If a wrong weather call costs you thousands — not just an inconvenience — this is for you.
Pour windows, cure conditions, freeze risk, and rain timing. Know whether to pour, delay, or blanket — before your trucks are loaded.
A failed pour costs $5K–$20KWind limits, seal temperatures, moisture on deck, and safe-access windows. Know if your crew goes up today or stays down.
A safety incident is catastrophicMulti-trade coordination across concrete, framing, roofing, and paint crews. One briefing that tells you which subs work which days.
Schedule delays carry liquidated damagesWind, lightning, and ice thresholds for bucket truck operations. Job-site-level forecasts for line work, tree trimming, and tower climbs.
Wind/lightning = mandatory stand-down48-hour confidence windows for tent decisions, indoor backup triggers, and guest-comfort forecasting for outdoor events.
A wrong call risks a $50K+ eventApplication temperature windows, humidity for cure times, rain-free hours post-application, and dew point monitoring for surface prep.
Rain on fresh primer = full redoThe average construction operation loses tens of thousands per year to weather surprises. One avoided disaster covers your subscription for a decade.
"I got tired of watching good operators lose money to forecasts that weren't built for them."
Jonathon Grassi is a weather analyst and the founder of MesoscaleWX. He builds every briefing from NWS forecast discussions, mesoscale model data, and local terrain knowledge — then translates it into the operational decisions that outdoor industries actually need to make.
