All right! It’s finally time to get a forecast under our belt this month. We’ll do so with a trip to northern California, where last summer the concern was wind and wild fires. It’s been much wetter this year, so let’s hope the fire danger is mitigated.

At 758AM, PT, Yuba City was already reporting 79 degrees under fair skies. High pressure dominated the west coast, and it promised to be a hot day in the central Valley. An excessive heat advisory was already in place.
There is a weak undercutting wave moving through the north Pacific that will arrive tomorrow, and may bring some high clouds and perhaps a dose of cooler weather on Thursday. The upper ridge will diminish through the period, but the low level thermal ridge isn’t expected to go anywhere, and even if temperatures moderate, it will still be hot.
