Frequently Asked Questions

Learn more about Weatheradar’s weather parameters, their units of measurement, and what values to pay attention to.

Atmospheric Parameters

Pressure refers to the atmospheric pressure at sea level, measured in hectopascals (hPa). Values higher than 1020 hPa often indicate clear skies, while values below 1000 hPa may signal storms or unsettled weather.

Humidity represents the percentage of water vapor in the air. Higher values (above 70%) indicate sticky or humid conditions, often preceding rain or fog.

Temperature Parameters

"Feels Like" accounts for wind chill or humidity, making it feel colder or warmer than the actual temperature. For example, wind can make a day feel colder, while high humidity makes it feel hotter.

The dew point is the temperature at which the air becomes saturated and water vapor condenses. Higher dew points (>20°) indicate humid conditions, while lower dew points (<10°) mean drier weather.

UV and Precipitation

The UV Index measures ultraviolet radiation from the sun. Values 0–2 are safe, while values 6+ require sun protection (sunscreen, shade).

Precipitation Probability is the chance of rain or snow. Values above 50% indicate a moderate likelihood, while values above 80% suggest you should carry an umbrella.

Chicago’s weather forecast today

Why do you need to check your weather forecast for today? Well, mostly that’s because in Chicago, the weather is always a wildcard. One day you’re basking in the sun along Lake Michigan, the next you’ll be bracing yourself against a wind that slaps you in the face so hard that it feels personal.

Locals know: in the Windy City, checking the forecast is more like taking directions from gas station employee along the road — you have to double-check the info every couple of hours to stay safe.

What weather to expect today in Chicago?

Depends on who’s asking. Or rather, when they’re asking. Winter? That’s the season of serious layers, Arctic-grade puffer jackets, and frozen faces peeking out from under scarves. You can spot the seasoned Chicagoans by their intense power-walking style, perfected for getting from Point A to Point B without becoming a human-sized icicle.

Then spring comes… or does it? Chicago spring is a guessing game where sunshine one day could mean sleet the next. It's a test of hope and patience, with locals cautiously swapping parkas for rain jackets, wondering if this year’s spring will actually be real.

In any case, our team does absolutely everything in our power to update the answer to that question as fast and accurately as we can throughout the day, to help you stay alive and well in Chicago’s climate.
