The storm that didn’t snow much becomes the storm that can’t leave

. . . at least not yet.
The loop of low pressure that cut off from the mainstream of the jet stream is responsible for the big, wide storm located off our eastern US coast. Another loop over eastern Canada has been blocking the low near us and keeping the jet stream jammed up like a beach road at the start of a hot summer weekend.

Now it’s time to for the storm to leave.
But another shot of atmospheric energy is coming in, keeping the storm spinning in place and finally wringing out some more impressive looking snow over us.

So that’s how we get a forecast of steady snow into midday Friday.
That’s how we keep the gale-force gusts of wind through late Friday.
Then, finally, we get a nice day to melt the snow on Saturday.

Boston’s still looking for the swirling bands to dump up to 1/2 foot of snow on them. There’s a chance it may not happen at all, so stay tuned!
