PHOENIX -- A deepening low pressure system is moving toward the Southwest.
The storm will drag a cold front across Arizona tomorrow, and winds will increase ahead of that front today.
In the Valley, look for 10 to 20 mile an hour winds Tuesday afternoon, and even stronger winds out of the southwest on Wednesday.
Blowing dust is likely tomorrow as any rain from the storm would come overnight Wednesday night or Thursday morning.
There is a 30 percent chance of rain during that window, with a dusting of snow even possible at elevations as low as 6500 feet.
Lows will drop to the 20s by Friday morning in the high country after the storm passes.
Valley lows Friday morning will be in the mid 40s to mid 50s.
Thursday and Friday will bring sunshine and highs of only mid 70s for the Valley, and mid 80s are likely for the weekend.
