After a weekend of temperature relief, temperatures will be warming up again to start this week. Hot high temperatures are expected Monday-Wednesday, with Tuesday being the hottest day. Temperatures will be around 10° above normal for this time of year. A few locations could see record high temperatures, especially on Tuesday. With the return to hot temperatures, remember to practice heat safety. This includes limiting time outdoors during the hottest parts of the day. Also remember to drink water and never leave anyone in a hot car, including children and pets.
The chance for thunderstorms will increase during the Tuesday into Wednesday time frame as monsoonal moisture from the Desert Southwest shifts northward. The main threat with storms will be gusty outflow winds, cloud to ground lightning and locally heavy rainfall.
