Tuesday 20th of November Forecast

Good Tuesday morning,

The low pressure system that brought us high clouds yesterday is now over the Baja and moving into Arizona.

This will create a little southern flow, before the rain arrives on Wednesday.

Today will start out with clouds, and then we will clear to sunny skies.

Tonight the low pressure system moves closer. The rain will really start up later in the afternoon on Wednesday now.

There could be a few pre-frontal showers in SLO and northern Santa Barbara County in the morning.

The real rain will start around 4 pm. We will see a 4 to 8 hour period of rain.

The jet stream is aimed at SLO and Santa Barbara counties; this means they will have the highest rain total.

LA and the fire areas, now look to see a little less.

The totals have backed off slightly. Now calling for 1/2 to 3/4 coastal and 1 to 1 1/2 in the mountains. LA around 1/3 to 2/3 of an inch.

Rain will all be over by Thanksgiving morning. It will be cool and damp, however dry Thursday and most of Friday.

Slight chance of rain in SLO and northern Santa Barbara county Friday night. This will not produce much rain at all.

Beyond that we are looking dry through Tuesday of next week.

This appears to be a 1 and done rain event, for this week at least.

It will give us all a chance to enjoy family and the holiday without rain.

Especially for myself. I will not need to be on roofs Thursday patching because the rain will be over.

If you are heading to Mammoth mountain for Thanksgiving, I have good news for you.

You will have a white Thanksgiving.

You will want to leave early Wednesday or you will be driving in snow and rain. There will be 9 to 15 inches of snow, mainly Wednesday afternoon and night.

Thursday will be nice then, very windy Friday and a little more snow.

Your best days to get outdoors will be Thursday, Saturday, and Sunday.
