PHOENIX — A blast of cold air is settling into Arizona behind our latest winter storm.
Valley temperatures will plummet into the 30s early Friday morning with frost possible in outlying areas by sunrise.
Freezing temperatures are expected across Pinal County and Pima County overnight with Freeze Watches and Warnings in effect heading into the weekend, too.
If you live in Casa Grande, Maricopa, Florence, Coolidge or outlying areas of the Valley, you may want to cover your sensitive plants in the overnight hours.
Another quick-moving disturbance could bring a few more snow showers to northeastern Arizona Friday night and early Saturday, but our Valley forecast will stay dry.
Our next big storm system moves into Arizona on Sunday. Winds will pick up, temperatures will drop and more rain and snow will fall.
This storm will impact outdoor events/activities and travel across Arizona, so Sunday will be an ABC15 Weather Action Day. Take action now to get ready for this storm.
We could see a tenth to a quarter of an inch of rain in the Valley and four to eight inches of snow in parts of the high country. (These estimates can, and likely will change as we get closer to the storm's arrival, so stay tuned for updates in the days ahead.)
Temperatures will stay cool through the weekend with Valley highs mostly in the 50s.
As colder air settles in behind Sunday's storm, we will likely see the first freezes of the season for many Valley locations on Monday and Tuesday mornings.
