Winter road weather for highways, cities, and airports
Whether you manage highways, a city, or an airport, your winter weather challenges are unique. Find out how Xweather Horizon addresses yours.
Highways and interstates
A large highway network means managing conditions across terrain that can be genuinely hard to predict: elevation changes, microclimates, and weather that varies dramatically from one route to the next. Regional forecasts are rarely enough.
Xweather Horizon gives you hyperlocal, route-specific forecasts across your entire network in a single view, so you can take proactive steps to treat the right roads at the right time.
Every treatment decision and weather condition is automatically logged by route segment, giving you the records you need to demonstrate duty of care and keep the public informed.

Community roads and streets
When you're managing winter roads with a small team and limited resources, blanket treatments aren't just wasteful, they're unsustainable.
Xweather Horizon gives you the confidence to treat the roads that need it, when they need it.
No existing weather infrastructure? GroundCast wireless sensors give you accurate road surface data with zero maintenance. Xweather takes care of data quality for you.

Runways, taxiways, and aprons
You already have comprehensive atmospheric forecasting. Xweather Horizon tells you what's happening at ground level.
Surface temperature, grip, and precipitation forecasts give your team continuous awareness of conditions across every runway, taxiway, and apron, with automated alerts the moment thresholds are crossed.
Vaisala RWS200 reference-grade weather stations and wireless GroundCast sensors provide the data behind every forecast.

Multiple data sources, one operations platform
Data from GroundCast wireless sensors, Vaisala RWS200 road weather stations, MD30 mobile plow detectors, and connected vehicles feed into the forecast model.
The model produces a 72-hour road weather forecast covering surface temperature, grip levels, precipitation type, and accumulation for each segment.
Teams generate targeted treatment plans based on forecast conditions and agency policies. Work orders are routed to the correct crews directly within the platform.
Weather conditions, treatment decisions, work orders, and crew actions are logged together, creating a continuous compliance record of your operations.
From forecast to treatment to logged record
Xweather Horizon connects the full winter operations workflow: forecast, plan, dispatch, and log. Agencies retain a complete compliance record as a byproduct of normal operations.
Forecast-driven treatment plans
Work orders dispatched to crews
Compliance logging
The tools behind every winter decision
Xweather Horizon provides the tools winter operations teams use daily, from network-wide forecasting to treatment decisions logged for compliance.
Insights dashboard
Identify critical events across your network at a glance. The dashboard transforms complex weather data into clear operational views. AI translates complex forecasts into accessible summaries.
72-hour road weather forecast
Pinpoint when and where the weather will affect your roads up to 72 hours ahead. The road weather forecast is complemented by a 10-day atmospheric weather forecast.
Treatment recommendations
Xweather Horizon translates the forecast into route-specifc treatment recommendations based on your policies.
Map view
Monitor surface condition, temperature, grip, and air temperature with dedicated data layers covering your entire road network.
Alert notifications
Set thresholds for sensor and forecast parameters and instantly notify your team when ice forms, temperatures drop, or grip deteriorates beyond safe limits.
Operations management
Replace manual spreadsheets and disconnected systems with an integrated workflow for planning, approvals, acknowledgements, and stakeholder notifications.
Instant intelligence
Xweather Horizon delivers improved road weather awareness from day one, even for networks without any existing weather infrastructure.
- Point forecasts
See a location-specific road weather forecast for any point on your network, no hardware required.
- Network forecasts
See a 72-hour road weather forecast for every part of your network, giving you a complete picture of how conditions will develop by route and region.
- Connected car data
Tap into real-time friction and temperature data from connected cars on your roads to validate the effectiveness of your treatments and pinpoint sections that still need attention.

Ground-truth observations
See exactly what's happening on your network with road surface measurements from critical locations and problem areas such as bridges, intersections, and inclines. These ground-truth observations enhance forceast accuracy, reducing short-term errors by up to 70%.
- Wireless road sensors
Vaisala GroundCast is a wireless, in-ground road weather sensor that measures road temperature at three depths, residual salt, and surface state. A standard subscription includes five GroundCast sensors for your network.
- Mobile detectors
Vaisala Mobile Detector MD30 collects and transmits road-surface state, grip, and surface-temperature data directly from your plows, with the option to drive dynamic spreading systems using the same data.
- Fixed weather stations

A service that scales with your network
Xweather Horizon accommodates agencies at every scale.
A small rural town or village with no existing weather infrastructure can start with a handful of GroundCast sensors and a set of forecast points for its primary routes.
A city managing multiple maintenance districts and a mix of existing road weather sensors can expand its coverage with forecast points, giving every depot supervisor a consistent, real-time picture of conditions across all routes.
A regional road authority or state DOT managing a large network, dozens of fixed weather stations, and a sizable winter fleet can integrate all data sources into a single operational view.
Reducing unnecessary salt and chemical application has environmental benefits alongside cost savings.
Targeted treatment based on actual road conditions reduces runoff into waterways and soil contamination.
No blanket policies means lower long-term infrastructure damage from over-salting.

Frequently asked questions
Standard weather forecasts predict atmospheric conditions for a grid area. Xweather Horizon models road surface conditions for specific routes, accounting for surface temperature, grip, water film, ice, snow, and bridge-specific behavior. The forecasts are route-segment-specific, not grid-based, and update using data from on-site sensors.
