The US National Weather Service is saying that inland temperatures will be in the low 80’s today and coastal temperatures in the 60’s (See map here.) However, tomorrow will bring possible rain showers north of Cape Mendocino and Wednesday and Thursday could start off with an unseasonable frost. The US National Weather Service says, 

An approaching low pressure system will bring an unseasonably cold airmass to Northwest California Tue night into Wed. This storm system will bring rain showers and high elevation snow showers to the region late Tue through Thu. Light snow accumulations will be possible across the highest elevations Wed and Thu with frost and/or freezing temperatures possible in the mornings. Unsettled weather will continue through Fri as this storm lingers over the region.

“For parts of Western Oregon and large part of northern California, this is the driest January to April on record,” writes the National Weather Service. For all of Mendocino and most of Trinity and Humboldt in these first four months of the year, rainfall is the lowest ever seen.

The Weather Service points out that, of course there could be more precipitation in the coming weeks, but, they write, it “will take a lot of rain to shorten our deficit. Unfortunately, long range outlooks calls for little change, with below normal precipitation into mid-summer.”

Temperatures soared today across Humboldt and Mendocino.  Eureka broke a previously set record for this date.  It reached 73 degrees today and the previous high was 68 degrees set back in 1998. Ukiah tied its previous record  of 92 degrees set back in 1966.

Garberville/Redway area reached 90 degrees as did Potter Valley.  Willow Creek topped at a ‘mere’ 89 degrees while temperatures rose to 97 degrees near Covelo.

Temperatures are expected to continue high through the weekend.

The US National Weather Service announced this evening that Eureka set a new April 24 temperature high of 70 degrees.  The old record, set in 1913, was 68 degrees. (Note: the official spot to take the temperature is Woodley Island.  Areas of Eureka further inland probably had even higher temperatures.)

The US National Weather Service in Eureka is issuing a frost advisory tonight.

Clearing skies and diminishing winds will allow temperatures to drop and frost to form across portions of Northwest California late tonight into Sunday morning. A frost Advisory has been issued overnight for cold temperatures across the interior valleys of Mendocino, Humboldt, and Del Norte Counties.
