Wet May Weather Continues across Western Wyoming and Star Valley

Wet May Weather Continues across Western Wyoming and Star Valley

It has been a very wet May across most of Wyoming so far.

For Star Valley will use the record from Star Valley Ranch as an example. Through the 25th of the month the Star Valley Ranch station has measured 4.42 inches of precipitation  There has  been measurable precipitation at the station for 13 consecutive days through this Saturday. It has also been unseasonably cool much of the time.  This is illustrated by the fact that there has been at least a trace of snow or hail on the last 9 days through Saturday. It now appears that the last week in May will be not much different as low pressure systems continue to move across the west with periods of showers and possible thundershowers.  Snow will continue to be common in the higher mountains with still a potential for a few flurries in the valleys  such as Star Valley.

 

Looking at the departure from normal for precipitation for the past two weeks:

While there are a few drier locations such as Yellowstone NP, precipitation across all of Star Valley has been 200 to 300 percent of normal.

 

Following is a list of precipitation reports for the 4 days ending this last Thursday night across much of western and central Wyoming.
