Sacramento is expected to experience another day of intense heat with a moderate HeatRisk alert in effect. High temperatures may approach 100 degrees, particularly in Sacramento and the northern Sacramento Valley. According to the National Weather Service, "The National Blend of Models(NBM) advertises around a 20-60% chance of high temperatures reaching 100 degrees in the Valley/Delta and the thermal belts of
the foothills today." Although a widespread heatwave is not anticipated, the upper-level atmospheric pattern and light winds could push northern areas into triple-digit temperatures this afternoon.
Relief from the prolonged heat wave is expected as early as Wednesday, with cooler temperatures arriving due to an incoming trough from the Pacific Northwest. Forecasts predict temperatures in the low 80s and low 90s for the Valley and foothills, and upper 70s in higher elevations, along with increased humidity and wind gusts of 15-25 mph in the Valley and up to 30 mph in the Delta. However, the National Weather Service notes that "Little to no precipitation is anticipated at this time however, as the trough is lacking significant/efficient moisture to cause any significant precipitation concerns for the area."
Sacramento residents can expect fluctuating weather this week. The National Weather Service forecasts a brief warming trend as the weekend approaches: "Thursday, our pattern will begin to shift again, as a more zonal upper level flow overtakes the area, with a weak closed low off the Baja California coast and ridging developing the Four Corners Region." Fire weather concerns may increase by Friday, with northerly winds and low humidity raising the risk.
As the weekend approaches, temperatures are expected to remain 5-10 degrees above normal. While there may be some fluctuations in the forecast, a major heatwave is not anticipated. HeatRisk levels are expected to stay minor, with moderate risk limited to isolated areas in the foothills and thermal belts by Monday.
VFR conditions are expected to continue across Northern California, with surface winds generally below 12 knots. However, flyers and Delta commuters should be ready for gusts up to 25 knots later in the day. With changing temperatures and increasing winds, locals are advised to stay updated and prepared for the shifting weather.
