Coming up. Tomorrow is 11 degrees cooler: a high of 58° after 69° today.
Now. Gary/Chicago International Airport is 67° and overcast at 11 PM. The dew point is 66°, so the air feels oppressive. Gentle breeze from the west at 11 mph.
Today and tonight. Tonight falls to about 50° by 7 AM, under cloud.
The week. The warmest day ahead is Wednesday, near 71°, and the coolest tomorrow, near 58°. Rain is likely tomorrow (67%). Rain is possible Saturday (32%). The windiest day is tomorrow, with wind to 26 mph.
The sky now. The Moon is a waxing crescent, 26% lit, and stays below the horizon until dawn. The next full Moon is Sunday, Oct 25. Look for Saturn, bright in the south. A planet shines with a steady light where the stars around it twinkle. The Orionids meteor shower is active, peaking around Oct 21: at its peak, up to about 20 meteors an hour can be seen from a dark site. Cloud is forecast to cover most of the night, so the sky will be hard to see. The day is 11 hours 9 minutes long, 3 minutes shorter than yesterday.
