The National Weather Service in Sacramento is signaling a cool-down for the region after a period of above-average heat. According to the National Weather Service, temperatures are expected to dip into the mid to upper 80s through Thursday, with potential showers hitting parts of Northern California midweek.
Residents can expect temperatures to drop starting Tuesday as the upper-level ridging weakens. However, this will bring breezy conditions that might increase fire weather concerns. The trough over the Pacific Northwest will strengthen, boosting onshore flow and humidity. In the northern Sacramento Valley, temperatures will likely stay around 90 degrees, according to the National Weather Service "only a 20-40% probability of less than 90F for Redding/Red Bluff."
Wednesday could see some wet weather for the southern Cascades and northern Sierra, though chances remain slim with "around a 10% chance of total rainfall exceeding 0.10 inches in the aforementioned areas," according to the National Weather Service. The incoming system is also predicted to stir up westerly winds, prompting gusts that could surpass 25 mph across the region.
Cooler conditions are expected to continue into next weekend, with below-average temperatures and highs in the Central Valley staying in the mid to upper 80s. Some mountain areas might see light rain from Sunday into Monday. VFR conditions are anticipated across interior Northern California through Tuesday, with surface winds in the Central Valley generally below 12 knots, but stronger winds may occur near the Delta after 3 PM.
