…Thunderstorms Continuing to Focus Mountains and Deserts; Flash
Flood Threat Continues Through This Evening…
Plentiful moisture and instability will continue to allow thunderstorms to develop over the mountains and deserts where a flash flood threat continues through this evening. Drier air will move in from the southwest on Friday, and thunderstorms will be much less likely, mainly limited to the higher mountains. Humidity will lower Friday through the weekend. Fair weather will prevail from the weekend through most, if not all, of next week

A dramatic decrease in thunderstorm activity is expected during the upcoming weekend, and continuing through much of next week, as increasing southwesterly flow pushes much drier air into the region.
