Very warm, extremely dry and breezy conditions are expected across southeast Wyoming today and Wednesday, but some relief is in sight.

The National Weather Service in Cheyenne says a slow-moving low-pressure system will move through the area, bringing fairly widespread chances for rain showers and cooler temperatures Thursday and Friday.

"Many areas are going to see much needed rainfall these days, that will ease fire weather conditions, at least temporarily," the agency posted on its website early Tuesday morning.
