Autumnal Equinox is on hand

We've been experiencing some glorious fall weather at the Aerie the last few days. It's been cloudless and warm during the afternoons with the temperature hitting 70 degrees. At night, those cloudless skies allow the daytime heat to escape very quickly--you can almost watch the thermometer registering the cooling soon after 6 PM when the sun approaches the western horizon. The lows have been into the 30s. Since cold air is denser and sinks, the valley has had the colder temperatures and even a frost or two. We haven't had temperatures that cold yet. We had a pretty stiff breeze last night and into the early hours of the morning but that ended by noon and only an occasional light breeze.

The Equinox is soon upon us with it's equal day light hours and night time hours. The Equinox marks the first official day of Autumn and usually falls between September 20th and 23rd. This year, the Autumnal Equinox occurs at 15:44 UTC on September 22.
