Winter Storm Gorgon, as it was named by The Weather Channel, is making its way across the country at very high speeds; by the time it moves off of the Eastern Coast on Tuesday night, it will have brought snow to more than 2,000 miles of land in less than 48 hours.
This system has put advisories, warnings, and watches for cold weather and snow for about 22 states. All the way from Washington to New Jersey, this storm has dumped snow on a little less than half of the country.
The Northwest and the Rockies have already received some snow, but Washington received rain instead. This caused some avalanche warnings to be put into effect in much of that area, as well as several mountainous ranges in the northern Rockies.
Washington was the first state that this system impacted, and about 11 inches fell in the central region of the state. This was a mixture of snow and freezing rain which caused some localized power outages and knocked down some trees.
Mudslides also became a problem as Gorgon moved through western Washington, which left the roads impassable and even some motorists stranded.
The mountains of Montana and Wyoming received locally heavy snowfall, and the Tetons of Wyoming reported about 45 inches in just a 32 hour period. In Montana, 25 inches fell near Columbia Falls between Sunday morning and Monday morning.
As for the Plains and Midwest, the snowfall totals by state include 3 inches in North Dakota, 5.5 inches in South Dakota, 4.5 inches in Minnesota, 7.8 inches in Iowa, 5.7 inches in Illinois, 1.5 inches in Indiana, and 1 inch in Wisconsin.
This system will begin to simmer down some as it moves into the Northeast region, but there is a still a possibility for early morning commuters to experience some light snow in Baltimore, Philadelphia, and Washington D.C. About the same kind of conditions will also be present inland in cities like Pittsburgh, Harrisburg, and Allentown, but the snow will start a little bit earlier in those areas.
New York City may also see some light and dusty snow because some snow showers are possible in New England, but it is unlikely for any of the snow to accumulate. As we move into Tuesday night, this system will move eastward out to sea, but the lake-effect snow will probably kick up after it has moved out of the region.
As for the Northeast, only light snow is expected on Tuesday night. Any of the snow cover that does occur will be in the east or southeast of the five great lakes. Since this snow will be arriving during the early morning commute for Philadelphia, Baltimore, and Washington, it may cause more of an impact than 1 or 2 inches normally would. The temperatures will be in the 20s on Tuesday morning which only helps the snow to stick rather than melting on the pavement.
Motorists who frequent the I-95 corridor while driving haven’t had much experience with snow this season, because so far, Philadelphia has only recorded 0.1 inch of snow thus far. This is a large difference compared to the whipping 20.2 inches they had through January 4th of 2014. All of the large cities from Boston to Washington have had below-average snowfall totals so far this season.
On the other end of the spectrum, the I-95 corridor through Maine has seen large amounts of snow. Bangor and Caribou have seen 20 inches more than the average for this season.
