The coastal storm system that morphed from what was once Ida is now an old-fashioned nor’easter, the kind we often see during the winter months, but this one is magnified to levels that make it a storm of rare ferocity.
A huge part of this atmospheric equation is an equally massive ridge of cold high pressure to the north. The pressure gradient, or squeeze, between it and the coastal low is responsible for the sustained, strong winds (especially along the coast) and heavy rain.
The storm will be stubborn in its departure, with the northern high blocking its progress, and the resultant long duration through Friday will produce impressive rain totals, particularly over the eastern half of Virginia.
Another interesting note on this is that snow has been falling at the highest elevations of Highland County, well to our west. And… to answer the burning question of the day; if this were snow here, we’d be digging out from several feet!
