While one system moves out only a brief delay before more showers are possible

Posted at 2:54 PM, Mar 23, 2020

A decent rainfall Sunday into Monday with most places seeing .50-1" of rain but some areas actually saw 1.5" to as much as 3" but those higher amounts were limited to the Santa Barbara county mountains.

That low pressure system is already quickly exiting to the east, but we can already observe several cold fronts in the Pac NW ready to drop into California as early as late Tuesday bringing showers back to the forecast thru Wednesday.

The one exception to the generally quiet Tuesday could be some pop-up showers at higher elevations due to cold air aloft left behind by the exiting system. Winds will be onshore Tuesday resulting in coolish temps and locally breezy winds.

A cold front drops down the Central Coast late Tuesday night into Wednesday morning in advance of an upper level system across interior Oregon. Some organized rain may be possible near the front as it sags southward, then general light showers spread across the rest of the area as colder air aloft moves in. Snow levels start out near 5000 feet early in the day then start to fall by late afternoon to early evening. This storm system remains land-based with little over water trajectory, but it`s cold and slightly unstable.

Snow levels ultimately drop to around 3000ft by Thursday morning. What is interesting about Thursday is that coastal clouds and drizzle could keep some measurable precipitation going there but elsewhere Thursday should see activity winding down.

High pressure will build on Friday and Saturday for a warming trend, possibly back to normal temperatures by the weekend. In fact models actually show a quiet pattern developing after this week into April.
