One Storm To Rule Them All?
Posted by Pete Bouchard
"The board is set, the pieces are moving."
We're on the eve of what could be the biggest snowstorm in almost a decade.
We're drawing comparisons with the Blizzards of 2005 and 2003 (22.5" and 27.5" - greatest all time in Boston). Yes, that much snow will hammer the Commonwealth. Confidence is high, the models are jiving and you need to take this threat seriously.
With such a large, long duration storm, where do we get started? How about the timeline?
Startup: Early morning tomorrow. Pacing is intermittent and light. 2-4 by afternoon. There will likely be mixing - or even plain rain - along the South Shore much of SE Mass. including the Cape and Islands. This is where a lot of us will be standing around saying "what storm?"
Phase two of the storm will then engage after dark tomorrow evening. Heavy bands will erupt from our developing offshore nor'easter/blizzard and snowstorm "feeder bands" (these nor'easters are cousins of hurricanes...sharing some similar characteristics like wind and wave generation) will start wrapping back over New England.
As snowfall rates increase beyond the point where plows can keep up, roads are likely to become impassable near or after midnight Friday night into early Saturday morning. If you attempt to travel, it is possible you may become stranded. Don't be that person.
Snow will continue - intense and unyielding - through Saturday morning and into the late morning hours. Thereafter, we can emerge and start cleanup.
Things we're working on:
Who gets three feet?!? Tough call. In storms like this, the convective (Huh? Think t-storms) nature makes it impossible to tackle ahead of the event. When we're in it, we'll know. Keep in mind folks, there may be multiple sweet spots or bullseyes. That happened in the Blizzard of 2005.
The REAL endgame of the storm. We'll leave it at Saturday afternoon, but the last flakes may not fly until Saturday EVENING.
Cape Cod snowfall. Always a moving target. Mix/rain early Friday will cut down on amounts, but we'll really make hay when the storm cranks on Friday afternoon/Saturday AM.
