Gusty north winds developed in the north end of the Valley, and combined with the hot temperatures to dramatically lower relative humidity in the Valley into the single digits. This all made for high fire danger, and that will continue into Thursday, so Red Flag Warnings are up for much of the North State through Thursday afternoon.
Surface high pressure built into Oregon behind a disturbance that passed through there Tuesday, and that created a decent pressure difference between Oregon and California... which caused the gusty north winds. Redding saw gusts to almost 40 mph, while Red Bluff saw almost 30 mph gusts! This surface ridge will move inland some overnight, which should kick up the Jarbo Gap winds on the Ridge (near the Feather River Canyon) somewhat for the first time this season... although I suspect they won't be exceptionally strong. The north winds will gust to about 25 mph in the north end of the Valley Thursday, with lighter winds south of Tehama County. As the surface ridge moves into the Rockies by Thursday night, our winds will turn more southerly again, allowing relative humidity to recover.
Otherwise, upper level high pressure remains strong, so our temperatures will remain hot throught the weekend. No triple digit readings in the forecast, but the north end of the Valley will be close at times.
