I posted on Saturday (see Facebook & Twitter feeds) that I thought there was "remarkable" agreement amongst the computer forecast models for a mid-week winter storm (especially given their poor performance this season). Today, nothing has changed. For example, looking at the three main models which have a "simulated winter radar", there were few disagreements from the overnight model runs, in the placement or type of precipitation for Tuesday evening:
One of the remarkable things about this storm is that it will go on for two days in parts of the Northeast. There are two parts to the storm, but there may not be a lull in-between. Chicago's in for a blizzard, and there's a lot of pink and purple on that map, meaning power outages and traffic accidents. You can see our official forecast maps and more details about when and where, in our news story. But here's what the ice and snow maps look like this week straight from our forecast database (warning: later periods may not have been quality controlled by AccuWeather meteorologists).
As a result of this storm, roughly 33 states are covered by some sort of storm-related National Weather Service advisory this morning:
As much as 27 inches of rainfall has closed I-95 in South Carolina, as well as nearly 400 other roads and 165 bridges!
Over 17 inches of rain fell near Columbia, South Carolina just last night!
The extreme rain continues today, with the Carolinas in the cross-hairs. This one could be a 1,000 year event.
Hurricane Joaquin rapidly strengthened into a monster storm overnight -- this changes everything.
Will Hurricane Joaquin be the next "Isabel" or "Sandy?" Does it even matter?
It's not a matter of "if" but "where" the flooding footage you'll see on the news later this week will be from.
