Boston / SNE news stations love to take a pass on actually making a call for Cape Cod during storms like this. Always seem to cut the Cape in half with two shades / buckets of 8-12" & 12-18". Heads they win, tails you lose!
How long the primary system holds on over interior mid-Atlantic vs. transfer to the coast will be important for extreme southern New England areas.
12z NAM seems to transfer to coast a bit quicker with primary not making it as nearly as far north —> flatter run
18z AI-EURO ticking a hair colder and dials back the precip just a bit in northern New England.
Confirms widespread +1 foot with QPF ranging from 1.1-1.4 across all of MA, CT, and RI.
South Shore looks to be the jackpot.
Recent system this past Sunday/Monday a great example. Had Cape Cod modeled as rain for the majority of precip with no significant accumulations. Ended up with a widespread 4-6".
Another rare winter storm with minimal wind. Snow falling almost vertical so very easy to measure. Right around 3.75”, should end up +4” of heavy wet paste.
Performing well on Cape Cod despite accumulation not beginning until after 4PM.
