Rain Friday Night Into Saturday Plus Long Range Pattern Change Slowly Grinds Ahead
We have rain in the forecast for Friday night into Saturday which is nothing new around here lately. We have seen more rain they normal for months now and that part of the weather pattern remains intact for now. At least this time around it doesn't ruin the whole weekend and only takes out Friday night and Saturday. Sunday looks to be okay.
Rainfall from this weather system looks to be on the order of three quarters of an inch to an inch or so and it doesn’t seem to be too problematic. It all moves away and weather conditions improve Sunday with some sunshine returning. It will turn a bit colder Sunday into Monday but this looks to be a glancing push of cold air before the next weather system approaches for Monday night and Tuesday. This is a warm front cold front scenario with some showers Monday night into Tuesday. There could be a little snow or sleet at the start Monday evening for a cheap thrill especially inland. After this system goes by we will be waiting to see how weather models evolve and handle the very large scale changes that are going on the upper atmosphere and the stratosphere. Weather models seem to be grasping at how all of these large scale changes play out and having a difficult time coming to grips with it all. We like to spend our mornings absorbing the overnight models and waiting to see what the afternoon series takes us. We will tear this all apart later today. We all know about the polar vortex and the polar vortex split which is a done deal. Now it is a matter of seeing if this is ultimate pattern driver or is the action in the Pacific so overpowering that it trumps everything else.
