.DISCUSSION...
A dry cold front will sweep the region Friday night into Saturday,
bringing gusty winds ahead of it (primarily on Friday afternoon
into the early evening) and cooling temperatures to below normal
on Saturday. Expect downvalley east winds Friday morning to shift
west southwest during the afternoon, with gusts up to 20 to 25 mph
developing and lasting into the early evening. Winds overnight
into early Saturday morning may become light and variable for a
period but shift back out of the west southwest late Saturday
morning and through the afternoon. Afternoon high temperatures
around 100 degrees Friday will cool to around 90 on Saturday.
Despite cooler temperatures this weekend, MinRHs will drop from
15-20% Friday to 10-15% Saturday due to dry air behind the front.
