The week. The warmest day ahead is Thursday, near 70°, and the coolest tomorrow, near 52°. The days ahead look dry. The first freeze could come Sunday, a low of 32°.
The sky tonight. The sun sets at 6:55 PM. The Moon is a waxing crescent, 33% lit, and sets at 10:48 PM. The next full Moon is Monday, Oct 26. After dark, look for Saturn, bright in the east-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. The sky is forecast to stay clear: a good night to look up.
