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*
