The heat wave scorching Northern California is expected to persist into the early week, according to the National Weather Service Sacramento. Residents in the Valley, Delta, and Foothills have been cautioned about widespread Moderate to Major HeatRisk due to sustained high temperatures. While a Heat Advisory is in effect until 11 PM tonight, there's chatter about potentially extending the advisory into Monday, given the mercury's stubborn climb.
Treading up from previous forecasts, the sweltering weather continues Monday with highs potentially tipping at 102 degrees in some regions. Especially affected, the Delta, southern Sacramento, and Northern San Joaquin Valleys, along with the Foothill thermal belts, are bracing for what's still to come. The expected cooldown is set to start on Tuesday, with lighter showers possibly gracing us north of I-80 and higher elevations towards the end of the week. Despite these light showers, no significant precipitation or thunderstorms are anticipated at this time.
Relief from this early autumnal blaze seems to be on the horizon as the aforementioned ridge is predicted to degrade and the troughing from the Pacific Northwest to stir a change in our weather patterns. This change signals a descent in high temperatures to figures still hovering 5-12 degrees above seasonal norms but with cooler nights returning to mid-50s and low 60s by Tuesday.
As we move into Wednesday, cooler weather is expected due to a trough from the Pacific Northwest. High temperatures should drop to the upper 80s to low 90s, with the northern Sacramento Valley likely reaching the 90s. A minor heat risk will remain, signaling the end of severe heat. This cooling trend will continue into Thursday and Friday as a weather system approaches from the West Coast, bringing light rain to Shasta County and further lowering temperatures, as reported by the National Weather Service Sacramento.
