BOISE, Idaho — Hot and hazy conditions dominate most of our Friday, but late in the day, increasing clouds & incoming moisture could trigger a few isolated thunderstorms in far southern Idaho and northeast Oregon. Temperatures will again approach the century mark in the Treasure Valley Friday afternoon but this is the last abnormally hot day for awhile, as by this weekend, temps in the Boise area dip into the 80s for the first time since mid-June, but unfortunately, the trade-off for the cooler weather is widespread rain and storm activity.

Scattered downpours and isolated thunderstorms are expected to pop up across central and southern Idaho off and on throughout the weekend, with flash flooding possible in places. A Flash Flood Watch is in effect through the weekend for the Central, Boise and Owyhee mountains of Idaho, the Camas prairie, and much of eastern Oregon. The Treasure Valley can expect spotty showers and isolated storms as well from Saturday into possibly Monday.

If you are camping this weekend be sure to download our Storm Shield App and be alert for the potential of flash flooding. If you are out of cell phone range you should bring a weather radio which can broadcast these warnings to almost all areas. Remember that a storm miles away can turn a dry creek into a raging river in a matter of minutes, so please do not camp near any dry creek beds this weekend!
