Coming up. Tomorrow is 11 degrees cooler: a high of 54° after 65° today.
Now. DeKalb Taylor Municipal Airport is 58° and overcast at 10 PM. The dew point is 57°, so the air feels a little humid. Moderate breeze from the west-northwest at 15 mph.
Today and tonight. Tonight falls to about 45° by 6 AM, under cloud. No rain is expected for the rest of the day.
The week. The warmest day ahead is Wednesday, near 71°, and the coolest tomorrow, near 54°. The days ahead look dry. The windiest day is tomorrow, with wind to 21 mph. The first freeze could come Saturday, a low of 32°.
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-southeast. 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 7 minutes long, 2 minutes shorter than yesterday.
