Coming up. Tomorrow is 25 degrees cooler: a high of 59° after 84° today.
Now. Fairfield Municipal Airport is 73° and light rain at 10 PM. The dew point is 70°, so the air feels oppressive. Gentle breeze from the west-southwest at 9 mph.
Today and tonight. Tonight falls to about 51° by 8 AM, under cloud. Air quality is moderate (index 54): fine for most people, though people unusually sensitive to air pollution may feel it outdoors.
The week. The warmest day ahead is Wednesday, near 76°, and the coolest tomorrow, near 59°. The days ahead look dry. Frost is possible Sunday morning, a low of 34°.
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 15 minutes long, 2 minutes shorter than yesterday.
