Coming up. Tomorrow is 8 degrees warmer: a high of 43° after 35° today.
Now. Arapaho Pass is 20° and mostly clear at 10 PM. With the wind it feels like 9°. The dew point is 20°, so the air feels dry and comfortable. Gentle breeze from the west-northwest at 10 mph.
Today and tonight. Tonight falls to about 17° by 4 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 48°, and the coolest Monday, near 42°. The days ahead look dry. The first freeze could come tomorrow, a low of 15°.
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 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 11 minutes long, 3 minutes shorter than yesterday.
