Coastal Storm #4 Looking Less Potent Than The First 3


We are still looking at the possibility of another coastal storm early next week. However the upper air pattern is changing somewhat and at least right now it appears that the upper air structure here is less dynamic than it was in the other 3 storms. Each storm had a different character to it with different impact and outcomes. This storm will also have different impacts and a different outcome than any of the others.

Looking at the upper air it is far less organized. There is a lot of energy but it is running around all over the place rather than having one very strong short wave in play. The blocking high to the north weakens over the weekend and disappears. With all this energy running around it is hard to have confidence in the outcome. This afternoon's gfs has 2 waves of low pressure with a lead wave coming in Monday night and Tuesday with some precipitation followed by a second wave behind it on Wednesday.

Right now with so much noise on the models the best course is to wait until models settle down a figure out which if any of these short waves is going to dominate in the pattern. Right now I think the best forecast course is to have rain and snow in the forecast for Tuesday and again on Wednesday. Usually in situations like this the models wind up settling on on dominate wave and a weaker second system. For now we watch and wait. Longer term this should be the last one in this dynamic pattern we have been in; at least that is the hope.
