TODAY’S WEATHER DISCUSSION AND FORECAST:

..Good Morning.
..Rain is just beginning to fall across the area as of 9:00am.
..The area of Low pressure that has been sitting off the SoCal Coast, has finally begun to move Inland this morning.
..Light rain has been falling to our West over the Los Angeles, San Diego and Ventura Counties since dawn today. Showers will increase today as the Low moves East across the Region. Estimated rainfall amounts will be the greatest along the West facing slopes with up to .75″ possible due to Orographic lift there. Up from yesterday’s estimates of .25 max.
..For the mountains, rain will be likely off and on through Tuesday morning. Snow levels will be running above 7500′ locally. Rainfall totals across most of the area will be from .25-.70″ of rain possible through tomorrow.
..The Dynamics of this system are pretty weak so the chance for a Thunderstorm or heavy rain is not likely as it looks this morning. A couple of areas of Vorticity will pass over today, one around 2pm and another overnight. This is when we will see the best chances for more consistent rainfall.
..As the Low moves East tomorrow, we will see slowly clearing skies for all of SoCal. Temperatures tomorrow will remain on the cool side with daytime highs in the mid 40s to low 50s across the area.
..Then for Wednesday a Ridge of High pressure will begin to build over the Region with warming temperatures through the end of the week ahead. However, Thursday as the 500mb pressure builds in the Great Basin, we will see weak Santa Ana winds develop locally.
..Hopefully this rain won’t affect the progress on the HWY 18 project. RC*

TODAY’S WEATHER DISCUSSION AND FORECAST:


..Good Morning.
..This morning, a weak Trough is passing over SoCal. As a result, the Marine layer has moved inland and is up to around 5500′ thick, with fog and clouds along and below the Rim.
..This will slowly clear out today as the Trough moves out of the area. However morning fog and low clouds can be expected again overnight and in the morning tomorrow.
..Temperatures will be running in the upper 50s to mid 60s today across the mountains as well as on Sunday.
..Late Sunday as a much stronger system approaches the West, we will see gusty winds develop along the Rim and front country in advance of a pretty wet system that will bring a good wetting rain to the area through early Tuesday morning.
..This system will have support of an Atmospheric River (AR) that will be dying out as it passes over SoCal. However, it will be strong enough to bring up to 2 inches of rain in some local mountain upslope areas. The recent burn areas need to keep watch over the recently burned hills for the possibility of flash Flooding or mud flows.
..The snow levels due to the AR from the South will keep those levels at 7500′ and above for this storm.
..As this will be the first rain that will likely cause some run off, this is a good time to check those drainage areas to make sure they are clear of debris.
..Tuesday and for the rest of the week ahead, we will have clearing skies and warming temperatures as High pressure rebuilds into the SoCal region. RC
..That’s it for now, have a good day! RC
