December 1, 2021 – Dry weather continues. Cool mornings with local fog in the Valley and mild afternoons expected over the next week.
Discussion
High pressure will remain over California this week. Temperatures will continue to be well above normal for this time of year with patches of fog developing each night near the central part of the valley and near water ways. This morning looks like the fog will be dense again for spots over the southern Sacramento valley and Delta especially when you get near I-5 and traveling west into the Delta.
For the foothills and mountains there will be some local gusty northeast winds early this morning over the favored locations. Local gusty winds 40 to 55 mph are currently occurring this morning but will weaken later this morning as surface high pressure weakens over the Great Basin.
Extended Discussion (Sunday through Wednesday)
High pressure remains the dominant synoptic feature through most of the extended forecast period. This will result in dry weather with above normal high temperatures into early next week.
A weak trough will bring some cooling to the region Monday into early Tuesday as it passes through along with the chance of some light precipitation.
Precipitation chances look to be mainly over the northern end of the valley and over the mountains at this time. A ridge of high pressure returns after the passage of the trough along with some northerly winds for the valley.
