TODAY’S WEATHER DISCUSSION AND FORECAST

Saturday, 04-18-2026
..Good morning.
..This morning we have clear skies with light winds from the North. Yesterday’s High temperatures from around some of the local areas were: Here at lake Gregory-60/32, Twin Peaks-63/37, Lake Arrowhead Village-56/31, Skyforest-54/41, Running Springs-62/33, Arrowbear lake-55/30, Big Bear AP-50/21.
..Today we are under a weak Ridge of High pressure. The surface winds will be Offshore for most of the day today along with very low humidity levels.
..As a result of the very low moisture in the atmosphere coupled with weak Offshore Pressure Gradient locally, temperatures today will warm by 5-10* locally.
..For Sunday. The Ridge will begin to move East and weaken over SoCal. An area of Low pressure will begin to affect SoCal late on Sunday as it slowly moves South along the California Coast. Onshore flow will slowly increase across the Region along with cooler temperatures as we head into early next week.
..Late Monday, the Low will begin to move Onshore across Central California. The trailing Trough will bring with it increasing humidity, Clouds and Gusty winds and eventually, a chance for a few scattered showers by early Wednesday morning.
..Onshore or SW winds will continue to help keep temperatures cool through the rest of the week.
..Another short wave to our West will develop into an area of Low pressure then move across SoCal bringing more gusty winds that will continue chances for light precipitation and or Thunderstorms through the end of the week. RC*
*My weather outlooks are derived from what I think will be the most likely outcome based on the most current information available.

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
