A large ridge of high pressure will be settled over the state of Wyoming today, Friday, and much of the day on Saturday.  Expect a mix of sun and clouds, breezy to gusty winds, and mainly dry weather conditions statewide.  Temperatures will also remain mild and above normal during this time.  Daytime highs will remain in the 40's and 50's.  A fast-moving weather system will slide across the state Saturday night into Sunday.  This will cause clouds to thicken statewide and there will also be a chance for flurries or light snow across northern, eastern and southeastern Wyoming overnight.  A strong Arctic cold front will then push into the region throughout the day on Sunday.  Expect partly to mostly cloudy skies, noticeably colder temperatures and developing rain and snow showers for the end of the weekend.
