A storm system will begin to impact Southern Colorado by late Friday morning. Mountain locations will simply see snow, but lower elevations will see rain eventually change to snow by later Friday afternoon. Locations that are higher in elevation will see the heaviest snow, due to them seeing cooler temperatures. So, Teller County, far northwest El Paso County, and the Wet & Sangre de Cristo Mountains will likely see several inches of wet snow. The major cities will see far less amounts and the storm will exit toward early Saturday morning.
Here is a list of local fireworks displays being held this Fourth of July:
