Yeah it is not like the Great Lakes though unfortunately, one day we will get ours though

I decided to wait until tomorrow's 6z runs before making a snowfall map. After 7 am.

I decided to wait until 7am or later for the first map tomorrow morning, I will update you once at 7 am and then again after 2 pm tomorrow.

Will, Scott, take a look at the 18z RGEM, it is putting down 2-3" of snow and the event isn't done yet on the model

18z RGEM is going gangbusters on the OES threat, over 2" of snow likely, WWA could be issued

I will issue my first call snowfall map at around 11pm

I can finally say with confidence, after watching the models the last four days the minute this threat come up, we are going to have our first Ocean Effect Snow event this season. After watching the model data come in today, I will watch the models tonight, and after the GFS comes to pass, I will update the snowfall map I expect for Thanksgiving, the key is accumulations are likely. Stay tuned!

NWS Taunton mentions snow accumulations likely from HYA eastward on Thanksgiving

NWS mentions snow accumulations likely Thanksgiving Day and night from HYA eastward

NWS mentions accumulations likely HYA eastward on Thursday

This Ocean Effect snow event is one of the better ones in quite a while.

Eastern Cape Cod, east of Hyannis, MA will receive the bulk of the snow threat. Several inches is likely. 850mb temp to the surface of the ocean differential (Delta Ts) are around +30 to +32C, and this will provide the kind of instability that will lead to thundersnows. This is what the Tug Hill Plateau sees and so does Buffalo with SW winds. However, the Cape does well with NNW and N winds at the surface, if we get any convergence we will see a singular band producing 2-4"/hour snowfall rates. This could surpass the events of the past. Stay tuned, snow map tonight after 00z models

Parameters increasing for a good Ocean Effect Snow event, eastern Cape Cod, east of Hyannis, MA. 850mb temps are decreasing to around -22C, and surface to 850mb winds turn more NNW or N for a time on Thursday, this is when the accumulations will be, right now NWS forecasts .5 to 2" of snow, but again this could increase later on in forecasts. Delta ts reach +30C extreme instability should make up for the presence of dry air, stay tuned!

NNE has a higher population, so of course they will win

I think the NWS is catching onto the OES potential from Hyannis eastward. Provincetown could get smoked.
