Tricky storm with rain/snow/sleet lines, but here are my latest thoughts:
Storm Headlines...
-Starts well after the evening commute Monday... between 9PM-Midnight from southwest to northeast.
-Initial burst of precip is mostly snow, even at the coast, and possibly the Cape too from Midnight-7AM.
-Snow turns to rain quickly at the coast, around the time of the Tue AM commute
-Despite turning to rain in Boston before/near the commute, the 3-4" that falls by the change-over time of 7-8AM, creates a slushy/slick mess
-Between 128 and 495, the morning commute features snow, heavy at times, and treacherous traveling. The mix there starts near commutes end. (10AM)
-Northwest of 495, the cold holds and it's mainly snow, from Worcester, points north through the morning. Change to sleet/frz rain there in the PM.
-Onshore winds are strong Tuesday morning, but not nearly as strong or as prolonged as last storm
-High tides also astronomically low... coastal flooding won't be nearly as extensive as last storm. Minor erosion/splash over still possible, but no major threats.
Snow totals... Look under "special map" for more
-South Shore coast... 1-3" change to rain by the AM commute. 2-4" interior SE Mass
-North Shore coast... 2-4" with 4-6" just several miles inland
-Boston will pick up 2-4" in the city, but up to 4-6" from Newton to Arlington and nearby towns/cities just outside Boston
-Route 128 belt features many towns picking up 4-6" before the mix with sleet and rain
-495 belt/Worcester features many towns picking up 6-8" of snow before a mix with sleet and perhaps some rain by mid-afternoon
-North of Worcester and just north and west 495 features 8-12" of snow with minimal mixing.

I hope I'm not jinxing us with this statement.."The recent wet pattern is over....onto sunshine & a more summer- like pattern.." The last time someone from 7 weather called a pattern change too soon we got a blizzard and 3 subsequent nor'easters (looking at you Pete!!--LOL). We don't have to worry about any blizzards or nor'easters but one never knows in the new world order.

If you were caught in those 'cloudbursts' today, you had more than you could handle in the rain department. Torrents fell in a short amount of time - what we deem 'flash flooding' in the weather biz. Since it happens suddenly, the National Weather Service has adopted the acronym TADD:

Bam. Pow! Those were some nasty storms last evening with some towns in metrowest & the city itself blasted with locally heavy rain, hail, lightning and strong wind gusts. A cool front is the culprit and that front will linger across the region again today. That means another round of some scattered showers & t-storms likely.

Heat and a bit of humidity fed a strong - and sometimes severe - line of thunderstorms today. By the time the dinner hour rolled around (6pm-ish), the storms had consolidated into a line. Everyone got a drink of water and a big drop in temperatures - some falling nearly 20 degrees in minutes!
