Star Valley Summer Remains Dry and Warm

Star Valley Summer Remains Dry and Warm

With school beginning  this week, the summer is drawing to a close.  Thus far the Star Valley summer months have seen very little precipitation with persistent warm days and typically cool nights.

Since the 1st of July only a few showers have been experienced  with little effect on what has been a very dry two months through the middle of August.  Star Valley Ranch has measured just .18 since June 20th and as of Friday the 17th only a trace for the month of August.  Other parts of the valley have not fared much better with about  a half inch at both Thayne and Smoot.  Bedford had just a third of an inch.

As can be seen the period from mid July to Mid August has been very dry across most of Western Wyoming

As striking is the percent of normal precipitation that has occurred during the same period.

While afternoon temperatures have been  very warm all summer the dry air and generally cloud free skies have resulted in cool mornings.

The summer heat peaked on Saturday, August 11 which was covered in the blog below

With the cool mornings the actual average temperatures were generally near normal

The remainder of August is expected to continue drier than normal although a couple of upper troughs could bring a threat of showers . Temperatures will gradually cool off as we lose a few minutes of daytime heating each day.

Outlook for the last week of August does suggest temperatures will be a little below normal but chances of precipitation remain on the dry side as the strong upper high remains over the Rockies  directing most Pacific storms well to the north of Star Valley.
