Cooler Temperatures, Lots of Incoming Rain For Wednesday

Temperatures will begin to turn cooler across the Cowboy state today (Tuesday) and through Thursday.  A slow-moving cold front will allow for plenty of instability and moisture across western and eastern parts of the state.  Today, there will be a very good chance for rain showers and developing thunderstorms over all Wyoming counties.  Best chance for thunderstorms will be between 3pm - 10pm tonight.  Some thunderstorms could be severe, with heavy downpours, hail, and very strong gusty winds.

Wednesday, a significant rain event is likely for southeast Wyoming and parts of the western mountains and canyons will see moderate to heavy rainfall at times.  This is going to produce a significant concern for some flooding and land slides in the more mountainous areas.  Rivers and creeks will be able to rise rapidly depending on rainfall amounts through mid-week.

Snow is a realistic possibility Wednesday night into Thursday morning across higher terrain areas along I-80 between Cheyenne, Laramie and toward Arlington.  A mix of snow and rain is also possible during that time across other parts of eastern and northeast Wyoming.
