Another week begins with many rain opportunities

by Dave Hovde, KSBY Meteorologist

An upper level trough digs out into the West with several areas of low pressure pushing over northern California between now and Wednesday.

The first is already here and rain will continue into the early overnight, locally heavy at times with the .50-1” potential (some locations could see as much as two inches).

SE winds will be locally gust with the system. Another low tracks into the area right on the heels of the first with more rain and about the same potential, another .50-1” of rain with locally higher amounts (graphics with potential are posted on KSBY and Dave Hovde’s social media @TVDave).

More SE winds prior to the next system also allow a connection to deep moisture, which helps explain the higher potential rain accumulations with the two systems.

After the second system pulls out Wednesday some high pressure builds in, this will help clear out the skies near the coast but some areas of dense valley fog may also result from trapped low-level moisture.

There is a third cold front, which looks to push into the area either late Friday or early Saturday for more showery rain.

I know the big question after that is the Christmas forecast and right now it looks pleasant as high pressure builds into the region.

Scattered showers continue through Friday evening, clearing for the weekend

By RaeAnn Christensen, KSBY Forecaster

Scattered showers will continue through this evening for the Central Coast. We are still seeing a slight chance for isolated thunderstorms as well. Quiet and cooler weather is expected for the weekend as high pressure moves into our area. But it is short lived. A series of weaker storms will bring unsettled weather to the area next week. Looks like rain on Monday, showers continuing through Thursday.

Most powerful storm in years sweeps through the Central and South Coasts, knocking down trees, power lines

By Dan Shadwell

Good morning! As the bulk of the pineapple express energy slides to the east of us, crews are cleaning up the damage left by the strongest storm system to hit the state in at least five years.

We saw widespread, significant rainfall–some of that coming so quickly that roads flooded and open fields filled with water.

High winds knocked down trees and power lines, leaving thousands of people without power.

Here’s a look at the rain totals as of about 5:45 this morning, and some of the expected high temperatures for the day for the Central and South Coasts:
Paso Robles–1.6″, 54
Atascadero–1.77″, 53
Santa Margarita–1.93″
Cambria–2.56″, 56
Morro Bay–1.59″, 57
San Luis Obispo–1.69″, 59

These 4 a.m. precipitation totals that are on the low side could be due to the storm knocking out the rain gauge or automated reporting.
