The National Weather Service says the temperature probably won't rise above 65 degrees today at Lindbergh Field in San Diego . If that turns out to be the case, it'll be the first time since record keeping began in 1875 that downtown San Diego has not risen above 65 on an August day. The existing record for the "low high" is 66, which has been recorded three times in the month of August, the last occurring in 1924. That's back when Buster Keaton was a big star.

Forecasters blame the cool weather on a low pressure system off the Pacific coast, which has been making San Diego's marine layer thicker. San Diego has been cooler, on average, than Portland, Oregon for most of the summer.

9 a.m. temperature snapshot: Lindbergh Field, 63; Sea World, 62; Point Loma, 60; Imperial Beach, 62; Red Beach, Camp Pendleton, 63; Oceanside Harbor, 63; UC San Diego, 63; Valley Center, 57; Fallbrook, 59; Escondido, 66; Ramona, 58; Santee Lakes, 62; La Mesa, 63; Mount Laguna Observatory, 71; Campo, 75; Alpine, 59, Poway, 61.

"A trough of low pressure will bring 500 MB heights 2 to 3 standard deviations below seasonal averages this weekend," the weather service says in an advisory. "High temperatures for the coast and valleys will be 10-15 degrees below seasonal averages, with temperatures for mountains and deserts a few degrees below average.

"This trough of low pressure will bring a deeper marine layer with coastal stratus extending inland into portions of the inland valleys each night and morning, then clearing back to near the coast each afternoon. Clouds may linger near some beaches each afternoon and there may be some patchy late night and morning drizzle from the deeper marine layer."

Inland San Diego County continues to be unseasonably cool. It was 86 Wednesday in Ramona (5 degrees below normal) and 89 in Campo (5 degrees below normal.)

The cooling actually goes back to ‘98. As that PDO kicks in more and more I just break out the popcorn and watch Goracle and Co. eat crow! LOL!

I’m preying that Gore’s place gets so much snow he won’t be able to dig out it for quite a while.

Here is his blog page.

For what it's worth, he was right on the money in last winter's prediction for here in Michigan............Little snow but lots of cold.

Is it usually cold in August in the Sacramento Valley?

Went to High School and College in Michigan. Know all about that kinda cold. Interesting to see what will happen this winter. Have La Nina instead of El Nino, plus a cold PDO. My guess would be less snow in Baltimore/DC area, but more in Michigan. The Northern Plains (Dakotas) also got a lot of snow last year, but it was mainly ignored because of the huge snows in Baltimore/DC. Had quite a few low rider El Nino storms come over Southern California and track up the east coast. Will probably see a lot more Alberta Clippers this winter.

It’s been a hot, humid, rainy summer in Illinois. I liked last year better. We only had the ac on twice last summer...
