A couple more rain chances but no huge storms

by Dave Hovde, KSBY Meteorologist

Another weak storm system is on the way to the Central Coast tonight. The track of the low is not ideal to produce much rain, most totals will be less than .25″ with the possible exception of the SLO northcoast.

While showers have begun much of Wednesday’s rain will actually fall later on this evening.

We are not done quite yet with rain chances this week, a still weaker front is on the way for late Thursday night into Friday morning but the front decays as it gets to the Central Coast, rainfall with this system will either be very light in the hundredths of an inch if it is capable of producing rain at all.

Temperatures remain below seasonal normals through Friday.

For the extended the models are in very good agreement that we’ll see dry weather Saturday thru Christmas with temps rebounding into the 70s (and 80s are possible in some locations).

Lompoc cold air funnel, why no warning?

by Dave Hovde, KSBY Meteorologist

Cold air funnels are similar to, but not, tornadoes.

These funnels typically form when you get very cold air over our heads and are associated with upper air lows or in jet stream troughs. This is the situation we’ve had in the area today and also had last night when a number of waterspout warnings were issued by the National Weather Service.

Cold air funnels rarely touch down (but some occasionally do) and unlike deep convective (thunderstorm style) tornadoes the wind speeds are low and damage is typically limited when they do have some contact with the ground.

Typically cold air funnels are not warned by the National Weather Service, they are very difficult to find on doppler radar due to their size and the fact they are not associated with rotating thunderstorms.

Cold air funnels and water-spouts are still possible today and tonight.

Scientifically they are not well-understood outside the basics described above.

Rain likely again this evening

by Dave Hovde, KSBY Meteorologist

The next storm will increase rain across the Central Coast this evening with showers and a slight chance of thunderstorms.

I expect rainfall totals will range from .25” to .75” inches with some localized amounts exceeding 1”

It is not just the amount of rain, but the rate to be concerned about, the bulk of this rain will fall in just a few hour period so expect locally heavy potential which could impact travel.

There are no watches or warnings for tonight’s storm yet, but stay tuned for updates.

A drying trend is expected Wednesday night and high pressure will slowly build over southwest California through the upcoming weekend and into Christmas week. However there is a very minor chance of showers Thursday and Friday but nothing on the order of what we have seen to start the week, and in fact that minor chance is only 10% but if your travels take you north the chances are higher.

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.
