UPDATED (7/9): Early start to Monsoon brings welcome rain back to Cowboy State

The monsoon season got off to an early start this year, as abundant moisture and instability were in place across Wyoming this week. This provided the needed ingredients, as weak shortwaves rotated around a high pressure center located near the Four Corners, for much needed thunderstorms to form across the area. Some of the thunderstorm activity was widespread across the forecast area for western & central Wyoming, with some storms becoming severe. These storms produced severe hail and in some cases brief heavy rain.  This event is much needed, as noted in the recent climate summary. Many locations have received much below normal precipitation since June 1 and this event will help against these deficits.  So far, only Casper has risen above normal for the year (as well as through June 1). All other locations are well below normal for the year (Lander is near normal for the year, but well below normal since June 1). Below are rainfall totals from Wednesday through Monday.
