Feels like

What it measures

The temperature as it will feel on your skin at this section: the air temperature, with the wind and the humidity worked into it. It is shown in whole degrees, such as 28°F or −2°C, beside the section’s own air temperature.

When a public weather model does not provide feels like, Windshield Weather calculates it from the available air temperature, humidity and wind using the US National Weather Service equations. Humidity can be calculated from the dew point. The result describes exposure outside the car; it does not measure the road surface.

Why it matters on the road

It matters the moment you stop — for a flat tyre, a fuel stop or a closed road. Wind chill describes how cold you will feel outside the car; on its own it does not say whether the road will freeze, which depends on the surface and its moisture.

That is why ice is flagged on Precipitation, not here: anything falling at or below freezing, judged by the air temperature, is marked HAZARD there.

How it is marked

A reading that crosses a threshold carries a small mark in the section’s CONDITIONS:

The mark is the same whether or not anything is falling.

A mark describes this reading alone. It does not change the section’s rating, which comes from the kind of weather forecast — see Severity.
