(Riverton, Wyo.) – The National Weather Service is predicting a warm and breezy day today in the Wind River Basin. See the weather story synopsis below:

SYNOPSIS:
An upper level disturbance will bring chances for showers and thunderstorms for day two of Severe Weather Awareness Week (April 21st- 25th) today. Best chances for showers and thunderstorms will come across the west, where gusty winds and hail will be possible this afternoon and evening. Breezy winds will also return across much of the area today, and some areas east of the divide will see high temperatures approach 80 degrees. These warm and windy conditions could elevate fire danger across central and southern Wyoming today, and cause minor to moderate rises on streams and creeks.
