Entering The Dog Days of Summer

A building ridge of high pressure over the western United States will significantly increase temperatures during the early part of the coming week. Expect daytime highs to run 10–15 degrees above normal for this time of year across the Northern Rockies. Temperatures will still cool off enough overnight and in the early morning hours to provide some relief. The "Dog Days of Summer" refer to what are generally the hottest weeks of the year in the Northern Hemisphere (July 3–August 11), which coincide with the rising of Sirius, the Dog Star.
