February 6, 2018 – Dry and mild for the next week except for a slight chance of light showers over the mountains next weekend and early next week. Patchy morning valley fog. Above average daytime temperatures.
Discussion
Strong high pressure ridging over the eastern Pacific will continue to dominate the weather pattern over the next several days. For the most part, conditions are too dry for significant valley fog this morning due to breezy northerly winds. Northerly surface gradients combined with northwest flow aloft will bring continued breezy north winds today. Overall airmass warms just slightly today but windier conditions could mix down slightly cooler air. Still bumped up forecast highs for today to closer to yesterdays values and may still see a few high temperature records set today. Surface gradients weaken on Wednesday so should see a decrease in winds. Airmass warms a bit more on Thursday bringing what may be the warmest day of the week with high temperatures pushing 80 in the northern Sacramento valley. A shortwave system dropping through the Pacific Northwest will bring a little cooling on Friday but highs will still come in well above normal.
Extended discussion (Saturday through Tuesday)
An upper level disturbance will bring scattered rain/snow showers to the mountains Saturday, although impactful conditions from any sensible weather will be minimal. Surface pressure gradient between two pressure centers across the valley will bring breezy to gusty winds Saturday and Saturday Night. Other than the chance for a stray mountain shower, dry weather will continue with above normal temperatures across northern California.
