Sep 8 QPF

Temperatures will hold steady in the 60s with a gusty NW wind Wednesday. Thursday stays breezy and it will be chilly with highs near 60. Friday the wind finally diminishes, but the clouds linger. The clouds could also produce a few light rain showers. All of this combined, will result in high temperatures in the mid-upper 50s Friday.

The weekend looks more like fall than late summer. High pressure will provide us with dry weather and a light wind.
