The July 2019 climate summaries for Big Piney, Buffalo, Casper, Greybull, Lake Yellowstone, Lander, Riverton, Rock Springs, and Worland are now available online.

July 2019 was slightly cooler across the Cowboy State. There were a few new daily records for minimum temperatures for some of these locations and also a few record highs, as temperatures quickly warmed up. Almost all of the climate locations saw their lowest temperature on the 9th or 10th and their highest temperatures on the 11th or 12th. In fact, Riverton broke a record low on the 10th and turned right around and broke a record high on the 11th. Precipitation totals across the climate locations were in the extremes with all stations either well below normal or quite a bit above. Big Piney saw only a few traces during the month putting it at 0% of it's normal precipitation (although data is suspect due to equipment issues). The runner up was Rock Springs at 3% of normal. Oppositely, Buffalo saw 168% of it's normal and Greybull 300%! Check the CLMs for more specifics on daily records set at the various locations.
