40/70 Benchmark Posted January 28, 2021 Share Posted January 28, 2021 Not bad, but I have had much better....I was too warm over the immediate coast of Cape Ann, southeastern MA, and the cape, where 1-3" fell, as opposed to the forecast of under an inch. https://easternmassweather.blogspot.com/2021/01/january-27-snowfall-verification.html Link to comment Share on other sites More sharing options...

CoastalWx Posted January 28, 2021 Share Posted January 28, 2021 I think the combo of very little onshore flow and good lift into the DGZ kept it a 32F snow there vs getting into the mid 30s like they would have with strong NE winds. It was also chilly just off the deck. 1 Link to comment Share on other sites More sharing options...

Yeah I didn't think much would happen there. Then at BOS, they stayed more nrly with the winds. The mesos had that too. Link to comment Share on other sites More sharing options...

USCAPEWEATHERAF Posted January 28, 2021 Share Posted January 28, 2021 Gulf of Maine is running between 5-7 degrees Celsius at the moment and with an airmass at 850mb as cold as -15 to -25C overhead, that puts our delta ts at +20-22 and 30-32C potential differentials. That is extreme instability no matter what numbers you want to use. Link to comment Share on other sites More sharing options...
