SACRAMENTO, Calif —
Temperatures soared well over 100 degrees in the valley on Saturday, and it was the hottest day of the year so far in most of Northern California. Sacramento hit 105 degrees, topping the previous maximum temperature of 104 on June 11.
Although Sunday will be a few degrees cooler than Saturday, most of the valley will still reach triple digits. Sacramento may be one of the few spots in the valley to not reach 100 with a forecast high of 99 degrees. The delta breeze will be stronger tonight and will arrive earlier, helping cool things down later this evening.
The ridge of high pressure supplying the sunny, hot conditions is slowly moving east, and temperatures will moderate day by day through Thursday before another warming trend appears likely starting late next weekend.
The cooling trend will drop temperatures to near normal by the middle of the week, which still means hot weather given it's late June. The average high temperature in Sacramento this time of year is 91-92 degrees.
The 90- and 80-degree high temperatures in the foothills and Sierra as of late will drop down into the 80s and 70s by the middle of the week. On Tuesday, thunderstorms are possible in the Sierra, mainly south of Highway 50 thanks to moisture moving into the region from the remnants of the first named tropical system of the year, Alberto.
Any cells that develop will be capable of producing heavy downpours, small hail and lightning.
Hot, sunny weather is expected to persist through at least the first week in July.
The Climate Prediction Center favors a continuation of dry, hot weather in Northern California through the next two weeks. Also noteworthy on the outlook is the robust monsoon signal in the southwest.
