Discussion by Dave Hovde

A ridge in the upper atmosphere continues to linger in the near the Central Coast through Friday, then a trough develops for Saturday and Sunday. What this will mean for Friday is warm interior valley temps again with highs near 100 (maybe just missing by a few degrees). The coastal valleys will likely clear quickly enough in the morning from any marine clouds to allow for 80 degree highs before a good afternoon return seabreeze kicks in to cool the late afternoon and evenings. The tougher call is the beach communities, Thursday the clearing was partial or only temporary as a stronger inversion cap has developed. This means beach communities should be in the 60s generally with some scattered 70s where clearing occurs.

The weekend looks cooler across the board with the trough encouraging a deeper marine layer (so cooler air penetrates further into the valleys) and stronger breezes. This will cut the interior valley highs back down into the 80s with 70s in the coastal valleys and 60s at the beaches. Morning clouds are probable with afternoon clearing.

If there is a trend exiting the weekend it should be toawrd some gentle warming with upper level heights increasing.

SUMMER COUNTDOWN: 5 MORE DAYS!!!!

ir

Here is an infared satellite image from late Monday night. It shows the upper level low pressure system spinning just north of the Central Coast. This very same system squeezed out a few sprinkles or light showers to the area Monday. This low is now moving east.

The forecast today will remain gloomy and overcast as more mid-level clouds spill in with another chance of showers. Today’s temps will be similar to yesterday’s with beaches in the mid 60’s and inland areas in the 70’s.

tuesday1

Wait until Wednesday gets here! Temps will up and we’re expecting 90 degree weather for some inland areas. I know, hard to believe after days and days of June gloom, right? Well it’s coming!!! 🙂

Here is a 850mb computer model to show you. Just in time too as summer is expected to finally arrive on Sunday! 🙂

Saturday was interesting. Friday we were talking about scattered showers and drizzle around the area in the on-air forecast. When we get this far out of season on forecast elements like this I will talk about them but generally couch my enthusiasm. What is interesting is that the forecast materialized as expected. I happened to be in Paso Robles much of Saturday, actually at the Ravine Waterpark. It was lightly raining, just a few drops to be honest, but the folks at the park were telling me they are getting off to a slow start because there have been too many cool days (and in the Paso-way 70s qualify as cool). Saturday afternoon cleared but got breezy, definitely not typical weather.

Sunday we are more clear as the the day starts, this is because a trough axis passed over us and is exiting…however there is enough instability around that afternoon heating could destabilize the atmosphere enough for clouds and some mtn. showers and storms but the chances are low and coverage should be isolated.

Monday and Tuesday are interesting in that computer models spin up a cut-off low off the coast. This will keep clouds in the forecast, temperatures cool, and even bring us 20% chances of showers.

Today’s satellite shows a lot of clouds hugging the coast for northern San Luis Obispo county. However, this is not the case. It is clear and sunny here along the coast this morning and with mild conditions expected for the rest of the day. The satellite is picking up high clouds but nothing in the form of marine layer.

It’ll be slightly

Forecast Discussion
by Dave Hovde

High pressure is parked over the Eastern Pacific with warm weather off to our east. This sets up a fairly common June pattern for the Central Coast. Onshore winds will prevail (breezy at times in the afternoon) with areas of night thru morning low clouds and clouds clearing back to the beaches in the afternoon.

The marine layer looks to firm up a bit and become more stubborn over the next few days which will drive temperatures down a bit. I think the coastal valleys will clear in the afternoons but the immediate beach communities could see lingering clouds or only partial or temporary clearing. The interior valleys will warm a bit over the course of the week, back into the lower 80s. Otherwise, beaches in the 60s and coastal valleys in the 70s.

More later today.
