Waking up to a whole new world this morning. Here in Swampscott, drifted snow is high and we're seeing accumulation totals at this point around 18 inches, with still another 6 inches expected throughout the course of the day. Will provide complete video coverage of the snowfall in a wrap up report later today.
No, it's not Genesis from the Bible (although, some may argue otherwise)... but bombogenesis is the technical term for what we're experiencing with this blizzard. After filing through either rather confusing or rather simplified versions of videos done on bombogenesis, I found this one from Accuweather.com that does a great job explaining the nuts and bolts of bombogenesis.
A look at the latest radar imagery shows the tip of the iceberg for the Boston area. A band of snow depositing 2-3 inches per hour is spinning northward from the Cape, where snow reports indicate the Vineyard already having 6 inches of snowfall. Boston is now seeing moderate snowfall as the Blizzard Warning officially goes into effect for the next 30 hours.
Watch for this same reaction from me if we're lucky to get some thundersnow in the heaviest bands late tonight and during the morning hours tomorrow morning in the Boston area.

There have been all manner of terms thrown around for this storm, 'historic', 'crippling', you name it. Here's one of the reasons those words are being used by even such responsible parties as the National Weather Service: there is a near 95 percent chance that Boston, which will be in the bullseye of this storm, will receive at least a foot of snow. Even if the forecast goes awry, as it sometimes does, there won't be any quibbling about a foot, there will be quibbling about 2 feet.
Updates will be coming nearly hourly as the storm gets underway, including live footage from the coastline, expected to receive an extra hammering from severe wind gusts and coastal flooding.
Ocean enhanced snow across the North Shore is already bringing an early taste of Juno's power. Cold northeast winds are already feeling like something wed be uncomfortable with and we haven't even got started. continued live updates become more frequent as the storm gets underway.
Feel that warm, humid, tropical air this morning in Boston? It is about to be swept out of the area by a strong cold front tonight. Along with the cold front -- the potential for some very nasty thunderstorms. The Boston area is in the National Weather Service's slight risk of severe storms (yellow color on the map to the left)
Any storm that develops randomly this afternoon could be severe, with torrential rain (think tropical). Instantly drenched. We are seeing a good deal of sunshine this morning in Boston which can help percolate the atmosphere and destabilize it even more as the cold air descends.
The next problem arises tonight. A squall line of storms expected to develop in the red area in the map will approach the Boston area and still have the potential for damaging winds. Stay tuned to Eppley Weather for additional details.
