Today we have Fog along the Rim as expected. An area of Low pressure is currently sliding South along the Coast of SoCal and is just offshore as of 7am. This will bring increasing clouds today with a slight chance for a rain or snow shower to the local mountains. Most of the energy from this Low will stay West of the Mountains toward the Riverside, and the San Diego areas, where that area will have a much better chance for Rain or Snow above the 4500′ level. All of this will clear out by late this afternoon, or early evening, today. Behind the departing Low, High pressure will build into Utah and the Great Basin, turning our onshore flow to a strong offshore flow. The NWS has issued a HIGH WIND WARNING for all of SoCal from 9pm tonight through 2am Wednesday. (A detailed text can be seen on the WX ALERTS page) As High pressure builds over the Great Basin and the Winds increase, cold air advection will bring very cold temperatures to the area. For Tuesday and Wednesday, mostly clear skies, strong gusty winds, and cold temperatures will be the Forecast. Thursday and Friday will be a little warmer as the High pressure over the West begins to break down. Then another change is on it’s way. An area of Low pressure will move towards the West Coast Saturday. Along with that there is a good chance for a warm Tropical fetch of Moisture to mix with the Low (Atmospheric River-AR). Sunday and Monday we may see a good soaking system move through SoCal.RC
That’s it for today. Enjoy the long Holiday weekend and be safe! Don’t drink and drive. Thank you for joining me @ lakegregoryweather.com.
