Current Meteorological Analysis for Chicago

Right now in Chicago, United States, atmospheric conditions are registering a surface temperature of 15°C, with an apparent "feels like" temperature of 14°C. Temperatures holding at 15°C (feeling like 14°C) create a cool, brisk atmosphere across Chicago, where light layering is recommended for outdoor comfort. Thermal sensation is governed by a relative humidity reading of 80% alongside sustained winds of 14 km/h arriving from the E. A high relative humidity of 80% paired with a dew point of 11°C maintains substantial atmospheric moisture, creating a heavier, muggier air feel that slows natural perspiration evaporation.

Atmospheric pressure currently reads at 1026 hPa. Pressure levels near standard baseline (1013 hPa) indicate balanced conditions, whereas rising barometric pressure typically denotes stable anticyclonic air that suppresses heavy cloud formation. Conversely, drops in pressure indicate incoming atmospheric disturbances or localized convective systems. Horizontal visibility across Chicago stands at 20 km, ensuring standard conditions for local roadway commutes and regional transit.
