A heat wave is expected to continue, with daily highs reaching up to 105. This could lead to the breaking of daily record highs. An upper-level high pressure system, or heat dome, is building and minimizing rain chances.

The heat dome is currently over the Desert Southwest and will remain in place for several days. After Thursday, it is expected to drift west into Arizona, potentially bringing a slight chance of rain to the area.

Further details about the heat wave and forecast are available from the ABC-7 StormTrack Weather Team, which has issued a First Alert for the affected region.
