USCAPEWEATHERAF Posted November 22, 2018 Author Share Posted November 22, 2018 Just now, dendrite said: Not odd at all. The winds were always forecast to back to a more northerly direction as the high approaches. Keep an eye on radar and keep hoping those NW-SE moving echoes start moving westward over time. Well I know that they are supposed to move more northerly and move back westward over mid-Cape. I just thought their movement was weird. Link to comment Share on other sites More sharing options...

You may be getting a little deeper lift and cloud formation up into that more northerly 850mb layer now. idk what else to tell you. It's not a classic OES setup even though you have some strong delta T's. Link to comment Share on other sites More sharing options...

Could that lead to thundersnows? Link to comment Share on other sites More sharing options...
CoastalWx Posted November 22, 2018 Share Posted November 22, 2018 I think the point we are saying is that any snows will be mostly east of the Cape. The elbow north of Chatham has the best chance of anything over 1" later. But, it's not a classic setup. Link to comment Share on other sites More sharing options...

USCAPEWEATHERAF Posted November 22, 2018 Author Share Posted November 22, 2018 the band just east of Cape Cod is strengthening as 850mb to surface differential is around 31C, extreme instability is developing now as the sunsets leading to enhanced snowfall for the Cape and Nantucket tonight. Just wait we will get our snows, after 5 pm EST. Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted November 22, 2018 Author Share Posted November 22, 2018 Winds are too westerly, not going to happen this time around, we still have the rest of the winter season to get a real event. 1 Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted November 23, 2018 Author Share Posted November 23, 2018 Ocean Effect Snow bands intensifying and producing heavy snow, as seen on the SPC mesoanalysis of precipitation type. A lot of moderate snows over the ocean northeast of the Cape. Snowing moderately in Truro and Wellfleet Link to comment Share on other sites More sharing options...
dendrite Posted November 23, 2018 Share Posted November 23, 2018 There’s no way there’s moderate snow there. Probably just some widely scattered flakes. Link to comment Share on other sites More sharing options...
USCAPEWEATHERAF Posted November 23, 2018 Author Share Posted November 23, 2018 Check out the latest BOX radar imagery near Chatham, MA, it is a rotating band of snow heading my way, it could be what is known as a mesolow that forms in bands due to intense instability.

You know SPC's mesoanalysis page, there is a parameter called Precipitation type, where numbers are the precip type, they have on their legend 7 SN-, 8 SN and 9 SN+, there are a lot of 8 and 9 numbers over the ocean in the bands.
