Excessive Heat Warning for the Grand valley through the week!
Triple digit temperatures have arrived and do not look to abate anytime this week. Records for GJ are in the very low 100s and the forecast has a tie or a new record set each afternoon through Thursday. The all time record high temperature for GJ is 106F established in 2005. There appears to be three days this week that could tie or topple that temperature. Drink plenty of water and take frequent breaks in the shade, check on friends and neighbors, watch pets on hot sidewalks and never leave a child unattended in a car (also secure your car to prevent a child from entering/getting trapped inside an unused vehicle).
Dry and mostly clear conditions continue as well. Once the forecast cycles through the midweek, added cloud coverage will be present due to an injection of moisture under the ridge of high pressure. This will not guarantee storms for the valleys, but a few mountain zones could pop off a round or two of thunderstorms. The hazard will be lightning fire starts with the very dry vegetation and no wetting rains. Gusty outflow winds will also amplify the fire hazard. Red Flag Warnings may develop late this week. Smoky conditions will also linger for the next few days in the Grand Valley due to the close proximity of the Pack Creek Fire in Moab, UT.
