Temperatures today were only a few degrees above average, opposed to the nearly 15 degrees above average we saw earlier this week. The one exception was Douglas County, where clouds kept places like Roseburg in the 60′s for most of the day. Tomorrow on the Fourth, everyone will see the warming trend begin again.
Not only will temperatures climb each day through the holiday weekend, but gusty winds and low relative humidity create a fire danger on Independence Day. A Red Flag Warning is in effect for the eastern portion of Siskiyou County, and most of Klamath, Lake, and Modoc Counties from noon until 10 PM Friday. Winds will be sustained from the southwest 15-25 miles per hour, with gusts between 30 and 40 miles per hour. Relative humidity values will be very low - between 5 and 15 percent. This means that any fires sparked by lightning recently, or any new fires that start, can spread rapidly. It’s just another reason to follow all regulations applying to fireworks on the Fourth.
As the weekend comes to an end, the baking heat will be begin again. Another strong high pressure ridge builds into the northwest, allowing temperatures to reach triple digits in the Rogue Valley and northern California. Isolated storms are possible next Tuesday in northern California and the Klamath Basin.
