Synopsis & Discussion
Forecaster: -M. Pace
Was another windy afternoon in Nogales yesterday, with wind gusts of 25-30mph. Today through Friday expect much of the same.

An area of low pressure will develop just north of the Great Basin, which will push an associated cold front and trough through the region. Currently forecasting winds of 20-25mph with stronger gusts possible Thursday through Friday.

The trough and cold front will sweep eastward this weekend leaving behind much cooler air. By Sunday, we could see stagnant conditions start to develop during the morning hours which could begin to increase PM-10 and PM-2.5 concentrations. This is something we will be watching closely over the next few days.
