Illinois – Warm, dry air is sweeping across Chicago this morning, and the wind is already picking up. Gusts will strengthen through the afternoon, creating a volatile mix of warmth and exceptionally low humidity.
Temperatures climb to near 66 degrees today with west-southwest winds gusting between 35 and 45 mph. That combination is triggering a significant fire weather risk across northeast Illinois and northwest Indiana.
The National Weather Service in Chicago warns that any spark could spread quickly in these conditions. Outdoor burning is strongly discouraged. Loose debris may blow across I-55, I-80, and Lake Shore Drive during peak travel hours. Secure trash bins and use caution with towing or high-profile vehicles.
A brief lull arrives tonight as winds ease and temperatures dip into the lower 40s. Clouds thicken again ahead of a wetter shift Thursday. Rain becomes likely by afternoon, and a limited severe thunderstorm risk develops across parts of northern Illinois. Gusty storms could redevelop before colder air filters in.
By Friday, highs fall into the mid-40s with breezy conditions lingering. The bigger headline arrives this weekend. Temperatures slide into the 30s, and a chance of snow develops Saturday night into Sunday. Even light accumulation could trigger flash freezing as daytime melting refreezes after sunset.
Next week starts colder but calmer, with highs in the low 30s Monday before gradual moderation. Longer-range outlooks signal a warming trend returning late next week, offering early spring warmth after this sharp February swing.
