Gusty Winds and Heavy Rain Today

The national weather service has issued a Wind Advisory from 2-8 PM for Eastern MA, the Cape & Islands, Southern Worcester County and Rhode Island.
NWS Boston headlines
This storm continues the active weather pattern of the last few weeks across the northeast. A triple point low will move northeast into Ontario/Quebec.  Notice the three fronts on the surface chart.  The first has temporarily (sorry) kicked the below average cold back to Canada. With this is the first slug of rain.
WPC surface analysis 8 am
The second boundary contains the heaviest downpours and perhaps some thunderstorms.  Here is the regional radar.
NWS Northeast Regional Radar
It's pouring in Maryland and SE Pennsylvania.  Philly is next for the heavy downpours. NYC gets it between 1-2 PM while New England taps the strong low level energy and is dumped on all afternoon.  The simulated radar at 4 pm

As the low level energy is tapped winds can gust 40-50 mph.  This is especially true in Southern CT, RI, Southeastern Worcester County up along 495 and east to the coast.
NWS Boston Maximum wind gusts 
Total rainfall is going to end up 1-2" in Southern New England.  There looks to be a bullseye across the Green and White Mountains which combined with the snow melt could lead to river flooding.
WPC total 48 hr precipitation forecast through Sat 8 am

Finally without trying to piss off everyone I mentioned that these 50s were temporary.  That is because we are back in the 30s and 40s this weekend.  It is possible we see some snow.
WPC surface forecast 8 am Saturday
Where is spring? That's a good question.  Perhaps some warmer weather toward the middle and end of next week. I'll have more on the potential snow as that situation evolves.
