Warm and dry weather with temperatures returning to average by mid-week.
Discussion
Clear skies cover the region early this morning. Stratus is extensive along the coast and the marine layer is around 1.5k ft deep. Surface pressure gradients are a little more onshore, and the increased Delta Breeze has brought minimal cooling inland to the Sacramento area while temperatures further inland are mostly up a few degrees compared to 24 hours ago.
Dry and mild weather will continue this week. Highs today will be similar to Sunday’s, perhaps lower by a few degrees as a short- wave passes to the north.
Ensembles shift the ridge further to the east by mid-week as a deeper trough develops over the eastern Pacific leading to a cool down in highs to around average.
In addition to the cooler temperatures, locally breezy southwest winds will be possible across the higher elevations of the northern Sierra Nevada.
Extended Discussion (Friday through Monday)
EPAC upper ridge builds inland over interior NorCal Friday. Models trending slower with progression of ridge and now keep CWA under its influence through the weekend. Pacific frontal system progged to weaken as it moves inland early next week.
Main impact for our forecast area looks to be increased onshore flow, some clouds, and cooling. Above normal high temperatures Friday, cool to 5 to 10 degrees below normal Monday.
