Showers and Thunderstorms Possible Weekend

The Ontario Weather Service Forecast Office has been watching Hurricane Dean as it hit Mexico, and the chance came that the Remnants of it could hit the Southland.  We are sure now that it will hit.  We have been chancing this for quite some time, but today we are announcing that we will see showers and thunderstorms from it across many parts of the Southland.
Because of the East flow around the vort center that will move over the area, we should see some of these push West of the local mountains.
High moisture content will allow for the chance of flash flooding in the Desert and Mountain areas, including the Hemet/Perris Valleys had any storms get going really good.

We are now 100% confident in a showers and thunderstorms event for most of Southern California, with the best chance of being the Mountains and Deserts this weekend. East flow can bring these over into the Valleys and Coastal areas as well, but a stable layer over Los Angeles may prevent them from making it to that coastal area, as well as the entire Palos Verdes Peninsula.
The mid level clouds may be over the area Saturday, however the chances of those are slimming down as each forecast comes through so there may be enough instability for Severe Thunderstorms, with hail, and flash flooding in the Mountains and Deserts. These chances are very real being we have 1.8-2.0 Precipitible Water to deal with so be careful if traveling. Do not cross flooded roads should you encounter them.
With so much moisture in the air, chances of at least some kind of precipitation will be across the entire forecast area.
Another interesting thing to note though is how far the track is away from us. This may mean a bit less moisture than earlier predicted so this will be watched throughout the day into the night, for a final forecast tomorrow.

My name is Kevin Martin. I am 23 years old, and just into the weather. I've studied it basically on my own for quite sometime. To be quite honest from 14 years old, I have spent over 75% of my free time on the weather where I still do it today. To show you a bit of what I do, please visit my site at www.ontarioweatherservice
.com I run the site. What it is is a forecasting site for the Southern California area. I have been doing this for 8 years, but archiving the site for two of those. This is my 8th year doing the Ontario Weather Service. I use to be just an email service in the beginning. No website. You'll find my forecasting ways pretty cool, and I even have some formulas. These formulas would help out FOX weather forecasts as well. I developed them on my own for santa ana winds, frontal zone winds, and even thunderstorm strength. Thanks for reading!
