Today and tonight. The warmest of the day has passed; it cools to about 54° by 8 PM. Tonight falls to about 41° by 8 AM, under a mostly clear sky. Air quality is moderate (index 57): fine for most people, though people unusually sensitive to air pollution may feel it outdoors.
The week. The warmest day ahead is Thursday, near 75°, and the coolest tomorrow, near 57°. The days ahead look dry. Frost is possible Sunday morning, a low of 35°.
The sky tonight. The sun sets at 7:04 PM. The Moon is a waxing crescent, 33% lit, and sets at 11:04 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. The day is 11 hours 12 minutes long, 3 minutes shorter than yesterday.
