Feb 2-3rd clipper threat

Recommended Posts

There is a wave coming down from Canada and there have been some interesting developments at H5. The wave isn’t super strong, but it looks like there is some strengthening as it hits ocean. There is also a bit of phasing going on, so although the vort is weak to start, the explosive development should occur as this over strengthens, expanding the precip field. It needs some work, but if this deepening occurs further west eastern mass should get some ocean effect snow. These type of events get overlooked but every once in a while a localized are wakes up to a surprised 3-4 inches. It’s probably going to be a lot less than that, but if this trends aggressively we have an outside shot at 2 inches of snow, so it’s still worth tracking.

What in the sam hell is this?

It’s a clipper threat. It still needs some work but the NAM has a shortwave diving down and going right underneath us. I would rather track clippers than continue to analyze 300+ hour pattern maps. Tracking actual storms beats tracking patterns any day.

I don't really think this is a clipper, but you can argue the main s/w energy traversing northern Maine is more of a clipper. It's ultimately an amplifying shortwave trough driving a sfc cold front through the region. Moisture convergence along the front as it pushes towards the coast results in a narrow area of precipitation (probably rain or a rain/snow mix).

Caribou NWS called it a "true Alberta Clipper" in disco other day. Don't know why the other Alberta Clippers are false.

Snow beginning, looking for up to 6". All amounts are welcome.

Certainly worth tracking here though the Connecticutians huff from the tropics of New England that it doesn't count.

Back in the day this type of system was always referred to as an Alberta Clipper.  And there were more of them back then.
