Thanks for the write-up. when you say the vortmax is pretty far west, i assume you mean on the models and not as observed right? Link to comment Share on other sites More sharing options...

Not to mention the GFS knowing its drier bias. None of the ones I saw have an actual map with accumulations yet. Just probability/percentage chance maps for a plowable snow. Forecast accumulation maps will start to come out tomorrow afternoon for the local stations I believe. Link to comment Share on other sites More sharing options...

Correct. It’s not actually in position in the middle of the country yet. It is still offshore. A chunk of it comes onshore tonight and then most of the rest will be on shore by 12z run tomorrow. 2 Link to comment Share on other sites More sharing options...

We had one decent storm in early December (10"), but the rest of the season was completely forgettable, and afterwards the only thing I really enjoyed was my ski trips to NNE, which did get some good storms. I'm much more hopeful for this winter. Nice to see more Rhode Islander’s on the forum. We can all ensure the pain of the snow hole together.

Like what are the synoptic features that would suggest this might come north? Latent heat release from storms originating from the south typically will have a northward correction as date draws closer. Normally once we’re within 2-3 days. 1 Link to comment Share on other sites More sharing options...

Greg Posted December 14, 2020 Share Posted December 14, 2020 I actually do have a weather question. Can the confluence to the north be equally as strong with a retreating High Pressure system just like an approaching High Pressure system? Just curious, I may be actually have an idea what the answer is but not 100% sure. Link to comment Share on other sites More sharing options...
