November 30, 2020 – Dry conditions with mild afternoons and cool nights are forecast through the week. Breezy north to east winds are expected Tuesday into Wednesday.
Discussion
Other than a few high clouds passing overhead associated with the trough moving onshore across the PacNW, skies are clear across interior NorCal early this morning. Current temperatures and dew points are a bit higher compared to 24 hours ago across much of the area, but readings in the 30s through the Central Valley are still cool enough for areas of frost again across early this morning.
The trough moves east later today, and as it does, north and east surface pressure gradients will tighten in its wake across NorCal. Breezy conditions are expected to setup later tonight across the Sacramento Valley and foothills of the southern Cascade Range. The result should be a little milder overnight lows tonight, especially along the western edge of the valley. Some patchy frost will still be possible along the more wind-sheltered eastern edge of the valley around daybreak Tuesday. Winds won’t be as breezy by Tuesday afternoon and Tuesday night, so early morning frost may become a little more extensive by mid-week.
Otherwise, dry weather will continue through the week with mild daytime temperatures and cool nights (outside of the foothill thermal belts).
Extended discussion (Friday through Monday)
Little change is expected through the extended period with a Rex block pattern deflecting the storm track to the north. Dry weather continues with mild, above normal temperatures in the afternoon and cool lows in the morning. Inversions will continue with more mild overnight temperatures in the foothills and lower mountains. Expect haze to build up at night in the Valley as the inversion acts as a lid, trapping pollutants.
