The extreme cold now freezing the Great Lakes and Northeast will ease somewhat as we go into the weekend, but more bitterly cold will air follow and will only ease slightly before Groundhog Day. This video has more.
Here are some maps showing snowfall totals observed and collected by the National Weather Service:
These reports cover the area from near DC to NYC.
This map focuses on the area around New York City.
The map below shows results for Connecticut.
This map for eastern New England is not complete nearest the coast because it was still snowing in parts of the area. Clearly, there was a great drop off in amounts from the South Shore (south of Boston) to Boston's northwest suburbs (where it was a relatively minor event).
Looking ahead to Groundhog Day and the Big Game, the GFS ensemble forecasts still show a wide range of possibilities, with gametime temperatures potentially as high as 40 or as low as the single digits. My prediction: this will resolve itself by game time.
...with almost 16 inches of rain in Myrtle Beach, South Carolina, and more than 20 inches around Charleston. You don't find amounts like that anywhere in the historic record for this area. This picture shows the radar-estimated rainfall over South Carolina between Friday afternoon and mid morning today:
This map shows where Hurricane Joaquin was just before 8 a.m. ET. You can also see the stripe of clouds centered just of the Middle and North Atlantic coasts.
There are competing forces acting on it, and each move it makes will place it under different influences. This has made it very difficult for computer models and meteorologists to judge where it will actually go. This is reflected in the track model collection on this map:
In assessing the final impact of the storm system coming into the East, there are three main components. First is the cold front coming across the Appalachians tonight in a very rich moisture field with ...
On this map, the cold front that will eventually move through the Northeast is in the far northwest corner of the picture. There are areas of showers moving northeastward well ahead of the front, but the steadiest rain is not likely until the cool air moves in and the front stalls.
The Midwest and Northeast are in the latitude zone where winds are primarily from the west. The direct opposite is the case today, as seen on this pressure analysis. The easterly flow brings in moisture from the Atlantic.
