Now. Plains Airport is 40° and clear at 11 PM. The dew point is 37°, so the air feels dry and comfortable. The air is calm.
Today and tonight. Tonight falls to about 28° by 8 AM, under a mostly clear sky. A freeze: protect plants and pipes. No rain is expected for the rest of the day.
The week. The warmest day ahead is Saturday, near 71°, and the coolest Tuesday, near 63°. The days ahead look dry. The first freeze could come tomorrow, a low of 28°.
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. The sky is forecast to stay clear: a good night to look up. The day is 10 hours 55 minutes long, 3 minutes shorter than yesterday.
