Pumped up East Coast storm: Where it’s worst Wednesday

Radar at 3:45 p.m. Tuesday ( Radar at 3:45 p.m. Tuesday (

This super-energized East Coast has it all:  severe thunderstorms in Florida, a deep and wide river of rain up I-95, and heavy snow on the north and western flank.  So far, airports have deftly weathered this juiced up storm, but they’ll face a steeper challenge Wednesday as it cranks up some more.

Here’s a concise look at the biggest trouble spots tomorrow (Wednesday) – the busiest travel day of the year:

New York to Boston – high winds/heavy rain: Rain will surge up I-95 as if it was shot out of a firehose late tonight into Wednesday. Travelers from New York City to Boston will face wind-driven heavy rains into Wednesday afternoon.

Wind advisories – for gusts up to 50 mph – extend from the Delmarva through southern New England. Some of the strongest winds are forecast from Providence to Boston where a high wind warning has been issued for possible gusts to 60 mph. Notes the National Weather Service: “Damage to trees, power lines, & property are possible with wind of this magnitude. Power outages are likely.”

Hazardous high winds possible in the Northeast Wednesday (

In Boston, the National Weather Service also warns of “widespread urban/poor drainage flooding” and has issued a flood watch through Wednesday afternoon.

Suffice to say, this wind/rain is likely to cause air travel delays throughout this region. And driving will be unpleasant..

Pittsburgh to Buffalo – snow: Especially early Wednesday morning, expect snow in West Virginia, eastern Ohio, western and central Pennsylvania, and western New York. Strong winds may lower visibilities in this area, making travel even more hazardous. In Pittsburgh, total accumulations of 3-6 inches are possible, with 4-8 inches in Buffalo. Conditions may improve some in this region during the afternoon.

24 hour snowfall forecast from European model between 1 a.m. Wednesday and 1 a.m. Thursday (

I-81 corridor: snow: As the storm is pulling away Wednesday morning and afternoon, a period of snow is likely from central Virginia (Harrisonburg) through the interior of southern New York (Binghamton) and the mountains to their west. Generally just an inch or two is likely around this route (highest amounts at high elevations, less than an inch in valley areas). In piedmont sections east of I-81 towards the big cities, a brief period of conversational snow is the most likely scenario, rather than accumulating snow.
