Synopsis and Discussion
A very cold trough of low pressure will move into the region from the northwest Thursday, increasing winds slightly in the Phoenix forecast area. Clouds will also thicken, giving the Valley a slight chance for a late Thursday night or early Friday morning shower. Totals, if any, are not expected to be much more than a tenth of an inch.
It's the cold air that has everyone scrambling for the winter clothes. Daytime temperature will drop from near 80°F on Wednesday to the low to mid 60s Thursday through Sunday. Overnight temps will be in the upper 30s to low 40s during that period. The cold snap will likely trigger an increase in Valley residential fireplace activity which in turn increases local PM2.5 pollution levels. So far this winter we haven't seen levels threaten the health standard at the monitors, but with less than a month to Christmas Eve, it is best to familiarize yourself with this season's pollution potential and how you can protect yourself as well as lessen the impacts we may experience.
