Following is the Weather Table for the Month of June at Thayne ES thus far

Noticeably is the the lack of any appreciable precipitation so far this June.
The current cool weather is the result of an upper trough of low pressure over the Northwest U.S.

This pattern will change over this next week leading to a large high pressure over the Western States.

Reflecting this forecast the 6-10 temperature forecast for the end of next week through the weekend calls for very warm
conditions in the mountain west

For the same time period the CPC is indicating that precipitation could be returning to the region.

This could reflect the beginning of the Southwestern Monsoon. So there is some hope of June ending on a wetter note, even with temperatures likely reaching into the upper 80s and low 90s by the end of next week.
