Temperatures Monday were much warmer than the highs from the weekend. Medford saw a high very near the century mark, but some locations in northern California made it into the triple digits. This heat wave continues for a large part of the week ahead, but we won’t be quite as hot by the Fourth of July.
The National Weather Service defines a heat wave as “a period of abnormally and uncomfortably hot and unusually humid weather. Typically a heat wave lasts two or more days.” Although the humidity is not a factor for us, temperatures will be above average for several days in a row. Along with the brutal heat Tuesday, some locations will see isolated storms. The low rainfall amounts and lightning, paired with the dry fuels in place, are cause for a Fire Weather Watch. This will affect most of Siskiyou County. It begins in the afternoon (along with the chance for thunderstorms) and continues until 11 PM Tuesday night. By Wednesday, a Fire Weather Watch also takes effect for portions of Klamath and Lake counties, due to the thunderstorm chance in the Klamath Basin.
There is good news on the horizon. A weak cold front moves through and drops temperatures back down to the lower 90′s for the Rogue Valley. Although above average, it will be around a ten degree drop from Tuesday’s highs. The Fourth of July will feature these “cooler” temperatures, as well as abundant sunshine.
