Dry weather with above normal high temperatures expected through the forecast period. Some breezy north to east wind possible at times through the week.
Discussion
EPAC high continues to slowly build inland over interior NorCal today. T-Td spreads attm similar to yesterday, so some mist or patchy light fog possible again from around the Sacramento area southward into the San Joaquin Valley this morning.
Tightened low level pressure gradient will keep some locally breezy north to east wind today in the Northern Sacramento Valley and northern and eastern foothills and mountains. Strongest wind expected through favorable oriented gaps and canyons, and over ridges.
High temperatures this afternoon forecast to be similar to Saturday. Pressure gradient weakens Monday as EPAC high retrogrades slightly back offshore. This in response to short wave trough progressing through W Canada.
Slight cooling expected as a result with highs on Monday near to a couple of degrees lower than today. Some mist or patchy fog possible again Monday morning in the same areas of the Central Valley as this morning.
Upper ridge then builds back inland Tuesday into Wednesday. 850mb temps trend up into the mid teens with high temperatures forecast in the 70s throughout most of the Central Valley.
Max temps in the Northern Sacramento Valley expected to top out in the upper 70s to around 80, which is near record values on Wednesday. Some locally breezy wind returns, in similar areas as today, as low level thermal troughing strengthens along the coast and over the interior of NorCal.
Extended Discussion (Thursday through Sunday)
Still no sign of precipitation as dry and mild weather persists across the region later this week under strong high pressure. Highs will be in the 70s to around 80 across the Central Valley, around 10-20 degrees above average. Overnight lows will mainly be in the 40s, about 5 degrees above normal.
