Fall’s arrival at 7:21 a.m. today might be especially sweet for Stockton, after a season stuffed with the most triple-digit days in a decade.

Temperatures hit 100 degrees or more 24 times over a nearly four-month period from late May to just this past Monday. The norm is about 18 such days.

That might explain why light showers and overcast skies likely came as a relief on Wednesday, though the record books will show that, technically, no measurable rainfall occurred here for the 121st consecutive day.

That’s a long dry spell, even if it does include summer months when very little rain typically falls, said Craig Shoemaker, a forecaster with the National Weather Service in Sacramento.

Monsoonal moisture often allows for at least a few summertime showers, he said. But that moisture just didn’t materialize.

“It’s been a little bit unusual,” Shoemaker said. “It’s just been shut off this year.”

And there’s no telling when the first real rain will arrive. Wednesday’s cool-down will carry over into today, but expect temperatures to climb back up into the 90s by Sunday, which is a bit warm for this late, Shoemaker said.

“At least it’s not 100 degrees, but it’s still a pretty big warm-up,” he said.

Longer-term federal forecasts through the month of December offer no clue whether conditions will lean toward wet or dry. Last year’s El Niño is history, and officials this week downgraded the odds for El Niño’s alter-ego, La Niña, making it even harder than usual to speculate what the winter might bring.

The federal forecasts do suggest warmer-than-normal temperatures are likely through the end of the year, however. Stockton saw its hottest year on record in 2014 and its fourth-hottest year in 2015.
