Lightning -caused fires are at the top of the list for things to watch this week. Thunderstorms will be possible in our northern counties through the evening Expect gusty winds, small hail and lightning-caused fires. There is thankfully some rain associated with these thunderstorms but its not an overwhelming amount. Fires caused by lightning will still remain a concern. There is a RED FLAG WARNING in place in Siskiyou and Modoc counties today due to this threat. This is not going to be like the August lightning storm catastrophe. Its too early in the season for that and the weather set-up is very different than what caused all of those fires last year.
Saturday will see highs back in the low-80s thanks to more cloud cover. Thunderstorms will not be as likely in Siskiyou county of the Coast Ranges but will certainly be possible in the Sierra-Cascades and in the east part of the Sacramento Valley against the Sierra foothills. The same concerns remain in place for these storms. On Sunday, more sunshine will bring highs back into the upper-80s. Thunderstorm chances will be reduced to Plumas county and south towards Tahoe. The rest of our region should be clear of the thunderstorms with mostly sunny skies.
Highs remain in the mid-to-upper 80s Monday and Tuesday with sunny skies and dry conditions. Tuesday and Wednesday could also be breezy at times.
There wil be a big cooldown on Wednesday as a broad trough of low pressure drops from the north into our region. This will bring mostly sunny skies on Wednesday with highs only getting into the upper-70s. This will be the nicest day of the week. Thursday and Friday look to see valley highs right around 80 degrees.
