The North Valley was sizzling today under the hot summer sun, and the heat got a boost from downsloping northerly breezes this afternoon in Shasta and Tehama counties with highs between 105 and 110 degrees. Despite our clear sky, it will take a long time to cool tonight. Lows in the mountains will range from the 40s to the 50s, with 60s and lower 70s in the foothills and valley. Thursday will be a mostly sunny, hot and breezy day, but it won't be quite as hot as it was today. There will also be a slight chance for showers and thunderstorms in our far eastern counties along the Nevada border, where a Fire Weather Watch is in place. Highs will range from the upper 80s and 90s in the mountains to the 90s and 100s in the foothills and the valley.
A weak disturbance will push over the Pacific Northwest Thursday through Saturday, but all it will do for northern California is bring slightly stronger breezes and a brief dip in our temperatures. Another warming trend will arrive late this weekend, and our highs and lows will remain at or above average through at least the middle of next week with no good chances for rain for northern California for the next couple weeks. We will also have a mostly sunny to sunny sky throughout the next week ahead. Daytime highs will stay quite warm for the mountains, ranging from the 80s to the lower 90s. The foothills and valley can expect mainly mid to upper 90s and lower to mid 100s for the next week. Overnight lows will remain mild, mainly in the 50, 60s and lower 70s.
