Saturday\u2019s intense heat across California<\/strong> will be the last major surge<\/strong> before a dramatic cooldown<\/strong> sweeps through the state on Sunday, June 1, 2025<\/strong>. A high-pressure system<\/strong> currently holding much of Northern and Central California<\/strong> in a grip of dry, hot air<\/strong> is set to weaken quickly<\/strong>, opening the door to cooler marine air<\/strong> and a pair of low-pressure systems<\/strong> that will bring relief from the heat and potentially even thunderstorms<\/strong> in parts of Southern California<\/strong>.<\/p>\n Inland portions of the Bay Area<\/strong>, including the interior East Bay valleys<\/strong> and the North Bay mountains<\/strong>, are forecast to climb back into the 90s<\/strong> \u00b0F (mid-30s \u00b0C<\/strong>) on Saturday<\/strong>, with heat advisories in effect from 11 a.m. to 8 p.m.<\/strong> Temperatures in the South Bay<\/strong> will be a bit more moderated, hovering in the upper 80s to low 90s<\/strong> \u00b0F (31\u201334 \u00b0C<\/strong>), thanks to increasing sea breezes<\/strong> expected by midafternoon<\/strong>.<\/p>\n Further inland, the Central Valley<\/strong> will endure even more intense conditions<\/strong>. Temperatures are forecast to peak between 101 and 108 degrees<\/strong> \u00b0F (38\u201342 \u00b0C<\/strong>) on Saturday<\/strong>, potentially matching or exceeding daily records<\/strong> in Merced<\/strong> and Hanford<\/strong>, both forecast to hit 105\u00b0F (40.5\u00b0C)<\/strong>. The Sacramento Valley<\/strong>, especially areas east like Roseville<\/strong>, could near 105\u00b0F<\/strong>, while Red Bluff<\/strong> and Chico<\/strong> may touch 107\u00b0F (41.6\u00b0C)<\/strong>.<\/p>\n Even San Francisco<\/strong>, often spared the heat, will feel a sharp split in temperatures due to its notorious microclimates. Ocean Beach<\/strong> may barely reach 60\u00b0F (15.5\u00b0C)<\/strong>, while neighborhoods farther east in the city could top 70\u00b0F (21\u00b0C)<\/strong>. Oakland<\/strong> is forecast to land just under 80\u00b0F (26.6\u00b0C)<\/strong>.<\/p>\n On Sunday<\/strong>, a marked temperature drop<\/strong> is forecast statewide as high pressure collapses<\/strong> and low-pressure systems<\/strong> move in from both the Southern California coast<\/strong> and near the Oregon border<\/strong>.<\/p>\n Expect highs to dip to:<\/p>\n This cool-down will also introduce more marine-chilled winds<\/strong>, helping stabilize temperatures that have hovered well above seasonal averages.<\/p>\n While Northern California<\/strong> cools off, Southern California<\/strong> braces for a new weather twist<\/strong>. The low-pressure system offshore<\/strong> is expected to interact with moisture remnants<\/strong> from Tropical Storm Alvin<\/strong>, leading to an elevated risk of thunderstorms<\/strong>.<\/p>\n The Sierra Nevada<\/strong> and Mojave Desert<\/strong> may see scattered thunderstorm activity on Saturday<\/strong>, expanding into the Antelope Valley<\/strong> and Transverse Ranges<\/strong> by Sunday<\/strong>. Rain showers and isolated storms<\/strong> are likely across Southern California<\/strong>, with Palm Springs<\/strong>\u2014which averages just 0.05 inches<\/strong> of rain in May<\/strong>\u2014possibly picking up 0.10 inches (2.5 mm)<\/strong> or more.<\/p>\n Erratic wind gusts<\/strong> and dry or wet lightning strikes<\/strong> are possible across this region, signaling heightened wildfire risk<\/strong> alongside the rare moisture.<\/p>\n Stay tuned for updated forecasts<\/strong> as the weather pattern shifts rapidly<\/strong> over the weekend, breaking the heat and introducing the first signs of an early summer monsoon influence<\/strong> in parts of California<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":" Saturday\u2019s intense heat across California will be the last major surge before a dramatic cooldown sweeps through the state on Sunday, June 1, 2025.
