Afternoon thunderstorms began about 4:30pm and lasted into the evening (11pm). Winds were very strong during afternoon thunderstorms.

The sunrises/sunsets have been beautiful but the air quality is horrible. Smoke from fires west of us in Idaho are being carried by the winds. The entire state of Wyoming appears to be covered in this thick smoke plume.
