Forecast Discussion:

We are marching along through October. Already half way through the month! Fall season weather is certainly upon us with mild afternoons and cooler mornings. The storm track this week is active meaning weather systems will periodically be carried along the jetstream, but remain north of the area for the most part. Temperatures and winds in the city respond accordingly throughout the week.

Relatively warm conditions and calm winds today through Wednesday transition towards a windy and cooler one on Thursday. Afternoon gust over 20 mph are likely. This pending event doesn’t seem to have the punch to result in local blowing dust concerns so a net benefit to our air quality is expected. Breeziness lingers for Friday helping to keep the airshed ventilated. Tranquil conditions then settle in for the weekend. This is to be yet another dry stretch. Hopefully, we can talk about rain again soon.
