Good Morning.
A Ridge of High pressure will move over SoCal from the West later today, and for most of Tuesday. There is an extensive cloud cover from the Coast to the IE this morning so expect to have fog along the Rim. Gradual clearing will take place as we transition to High pressure. Temperatures will warm up for later today, and for Tuesday, which looks like the warmest day of the work week ahead. Tuesday late afternoon or evening another warm area of Low pressure will move into SoCal from the West, bringing more rain to the area through Wednesday night. There will be some AR enhancement with this system for Wednesday, so rainfall amounts will run from 2.00″ to possibly 5.00″ in the wetter locations.
..Then scattered showers can be expected through Thursday night or Friday morning. On the heels of Wednesday’s system, cold air advection will bring lower snow levels to the local area for late Wednesday night Through Friday, possibly down to the 4500′ level at times.
..Currently, looking at the next system, on the GOES17 IR loop with GLM enhancement, there is lots of Lightning out over the Pacific to our West. This area will be worth watching as it moves closer to SoCal as there is lots of instability. This next system has a couple parts. Cold air wrapped in the Low, slowly moving in from the North West, and Warm air in an Atmospheric River, feeding up from the South, and in the middle where it all is coming together, lots of instability. So this could be an interesting storm for the upcoming mid work week ahead. This next weekend looks good at this time but another wet system looks promising for Monday and Tuesday.
..So as you can see, we are not out of the grips of winter just yet. March is the beginning of the Jet Streams’ migration to the North. However, as we have seen, it is a slow process, and sometimes very strong and cold areas of Low pressure develop and move South along the California Coast. While at the same time warmer and much wetter systems from the South collide with those areas of Low pressure over SoCal, such as March of 1991 when we had huge amounts of snow, and back in the early 80’s when it would rain all day, and then turn to snow all night for several days. What a mess that made of the roads!
..Also, thank you to those of you who have donated to this website as that really helps offset the costs of running the website and its associated subscription fees, equipment maintenance, and tech fees.
..That’s it for today.
..Have a good Day! RC
