TODAY’S WEATHER DISCUSSION AND FORECAST

..Good Morning.
..This mornings Fire update video. Click HERE
..So the weather has taken a change for the better for the Firefighters. This morning the humidity levels are up as well as the fuel moisture levels. This will really help in getting additional containment on the Line Fire. The Fire Weather outlook for today is for slow growth of the fire with slow creeping of spread. Cooler temperatures and winds mainly from the SE at 5-15mph. Humidity levels are up as well. At the bottom of Waterman Canyon the RH is @ 87% with light Fog. Big Bear has RH @ 34% up from the low teens recently with light winds mainly from the N @ 3-6mph. All good news on the fireline today.
..So for the weekend outlook weather wise, we will see much cooler temperatures throughout the weekend. The Valley and foothills will have morning Fog as a deepening Marine layer develops and moves Inland during the next several days.
..An area of Low pressure is currently passing through the PAC-NW. This will help to bring gusty South to SE winds to our area as well as Morning Fog to the Valley and foothills locally.
..The upper level flow will keep us in a Long Wave Troughing pattern across the West, with areas of Low pressure moving through the flow for the next several days.
..Temperatures will be much cooler especially on Monday and Tuesday mornings. The Marine layer will deepen up to around the 3500-4500′ level on those days. Drizzle and of light rain showers can be expected in the areas affected by the deep Marine layer. Wet roads will be likely as well so use extra caution when driving as this will be the first moisture on the roads for a long time making for potentially slippery surfaces.
..LOOKING AHEAD:
..Monday and Tuesday will be the coolest days of the next five. West Coast Troughing will continue through Thursday as a couple of systems pass through the PAC-NW.
..This will keep us in an onshore flow with morning Fog likely trough Thursday below the 5000′ level.
..As we head towards next weekend, High pressure will be sitting off the Coast of California, and will move Inland for the weekend bringing warming temperatures.
..Then another Trough will move through the upper level flow Monday with another cooling trend.
