CHEYENNE, Wyo. – Wyoming residents will see a mix of summer warmth and afternoon thunderstorms this week, with rain chances building toward Friday as cooler air moves into the region. Highs will stay in the 70s and 80s, with some spots briefly touching the low 90s before temperatures ease heading into the weekend.

By Friday, cooler air will shift into the state, bringing highs back into the 70s and producing more widespread showers across central and eastern Wyoming.
