The heat continues for northern California, but thankfully it isn't QUITE as hot as it was over the weekend. The Excessive Heat Warnings will now expire Tuesday night rather than Wednesday, but real relief won't arrive soon. Fire danger remains high in our area. The Red Flag Warning for western Siskiyou County expires tonight, but a Fire Weather Watch goes into effect Tuesday afternoon and evening for Lassen and Plumas counties due to the threat of isolated thunderstorms Tuesday. Tonight will be clear and quiet with lows ranging from the 50s in the mountains to the 60s and 70s in the valley and foothills. Tuesday will be bright and hot with isolated mountain thunderstorms. Highs will remain in the 90s and 100s for all areas.
The same strong ridge which took control of our weather late last week is and will remain in control through most of the short and long-term forecast. Isolated showers and thunderstorms will pop occasionally over the mountains, but the valley will have no good chance of rain or thunderstorm activity through at least the first week of July, if not longer. The strong ridge will begin to weaken this weekend through early next week as a trough of low pressure develops over the West Coast. We will begin to cool back to more seasonable levels, but it will remain hot for everyone. Valley lows will cool from the 70s into the 60s. Valley highs begin this week well into the 100s, but by this weekend and early next week we'll fall into the 90s.
