The NWS Medford expects thunderstorms to develop over a wide area of Southern Oregon including Klamath and Lake Counties on Monday. The storms could last from Monday afternoon through most of Monday night.

These storms will have the ability to produce cloud to ground lightning and strong outflow wind gusts. When thunder roars, go indoors! Go inside a house, car or sturdy building. Do not seek shelter under trees, stay away from water and/or metal objects. Since many areas where thunderstorms are expected are very dry, abundant lightning on dry fuels may increase the risk of new wildfires.

In addition to the thunderstorms, high temps in the mid 90’s are expected east of the Cascades and triple digits to the west.

Seasonable temperatures are expected through Saturday, but heat risk impacts increase Sun/Mon. Highs will be at or above 100°F in some west side valleys, including the Rogue and Illinois Valleys in Oregon and the Shasta and Klamath River Valleys in California. Plan outdoor activities accordingly. Temperatures should lower again toward the middle of next week.
