some changes afoot... (pm.23.oct.15)>

Friday's stats:

Low temp: 55.6F (13.1C)
High temp: 67.2F (19.6C)
Rainfall: none

Just like last evening, there are some high cirrus clouds scattered across the sky at dusk, otherwise we can call it mostly clear.  Temperatures continued to trend slightly lower today, though it was still very comfortable for the season -- thanks to abundant sunshine.  Clouds were again confined to the immediate mountain slopes during the afternoon hours.

A transitional period is on the way, as we watch a generally flat west-to-east upper-level flow replaced by an approaching low pressure disturbance/circulation over the course of the weekend into early next week.  Initially, this may not mean much for us, apart from an increase in mainly high cloudiness.  But computer models are showing better and better chances of scattered shower and thundershower development in our region by the latter half of the weekend, and especially during the Sunday evening through early Tuesday morning period.  Decent low-level moisture is lacking, but the upper-level energy may eventually compensate for that.  We will watch, of course.

By late Tuesday, there will still be an upper-level circulation nearby, but the next blast of drier air will be coming in from the north and northwest, setting us up for a quiet second half of the week.  Overall, temperatures will continue their gradual downward slide into more autumn-like conditions.
