Coming up. Rain is likely tomorrow evening, from about 8 PM, the chance peaking at 85% around 12 AM.
Now. Delaware Airpark is 62° and overcast at 11 PM. The dew point is 56°, so the air feels a little humid. Light air from the east-southeast at 4 mph.
Today and tonight. Tonight holds near 60°, under cloud.
The week. The warmest day ahead is tomorrow, near 82°, and the coolest Saturday, near 55°. Rain is likely tomorrow (85%) and Saturday (95%).
The sky now. The Moon is a waxing crescent, 26% lit, and stays below the horizon until dawn. The next full Moon is Monday, Oct 26. 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 13 minutes long, 2 minutes shorter than yesterday.
