A weak cool front and weather system will back into central and eastern Wyoming from the northeast today.  Expect early sunshine with slightly more cloud cover in the afternoon and evening hours.  There will be a chance for showers and thunderstorms in eastern portions of the state, while mainly dry weather conditions will be found elsewhere.  We can also expect breezy to gusty winds with very mild to warm and near average temperatures statewide.  Daytime highs will remain in the 70's and 80's.  Higher pressure will then build over the region on Friday, Saturday, and Sunday.  Expect plenty of sunshine, light to breezy winds, and mainly dry weather conditions throughout the state during this time.  Temperatures become cooler and will remain near or slightly below normal on Friday due to the cool front that passed through the area on Thursday.  We will then see warmer and above normal temperatures statewide on Saturday and Sunday.
