A powerful, multi-part storm system is bringing a real change in the season. On Wednesday, it delivered the first snow of the season to Colorado. Here were some of the snowfall totals:
Castle Pines (Douglas County): 5.3”
Ft. Collins (Larimer County): 6.0”
Loveland (Larimer County): 6.5”
Breckenridge (Summit County): 7.1”
Wheat Ridge (Jefferson County): 7.6”
Aurora (Arapahoe County): 8.0”
Denver (Denver County): 8.5”
Boulder (Boulder County): 10.5”
Evergreen (Jefferson County): 12.8”
Copper Mountain (Summit County): 18.0”
Jamestown (Boulder County): 19.8”
Now, how about snow in October in the Texas and Oklahoma Panhandles? Well, that is what has happened, today. Here are some of the snowfall totals as of 2PM CT (THU):
Boise City (Cimarron County, OK): 1.0”
Guymon (Texas County, OK): 1.0”
Panhandle (Carson County, TX): 2.8”
Wildorado (Deaf Smith County, TX): 3.0”
Amarillo (Potter County, TX): 4.5”
It is also snowing today in portions of New England from northwest Pennsylvania through the heart of New York state and into New Hampshire. Now the snow is ready to impact further south into the central Appalachians and possibly even the I-95 corridor from Washington DC to New York City.
Even while the majority of the modeling data have been leaning away from the potential for snow in the Mid-Atlantic and into New England, Saturday, as a result of a secondary low pressure system moving norhteastward out of the Southeast and up along the Atlantic Coast, I have been choosing to follow the ECMWF (European) for several days because of the confidence I have gained in this model over the past 15 years and because it has simply made sense and looked correct. Now, guess what is beginning to be shown by the remainder of the models, the potential for snow from DC to NYC.
As the piece of energy ejects out of the southern Plains, the one that brought the snow to Colorado and the Panhandles of Texas and Oklahoma, it will merge with a secondary piece of energy dipping southeastward out of the Upper Midwest. These two pieces of energy will form one storm over the Southeast, on Friday, and it will lift northeast along the eastern U.S. Coast. The current track thought would take it near the Delmarva, Saturday morning, to the Canadian Maritimes, Sunday morning. This track would produce a band of accumulating snow, Friday night through Saturday night, from northeast Tennessee into New England. The heaviest snowfall, 3” to 7”, will fall across the spine of the Appalachians in Tennessee, West Virginia, Virginia, Maryland and Pennsylvania and into the Adirondacks of New York. The southeastern edge of the accumulating snow will edge near the I-95 corridor from Washington DC to New York City. Further northeast towards Boston the chances of seeing snow increase further. I believe we will see some slushy snow into Philadelphia and New York City and rain will likely mix with and may briefly change over to snow in DC.

Another fast-paced storm system will roll through the center of the nation and off the East Coast early next week. This system will develop a low over the eastern Gulf of Mexico and take it across Florida and into the Atlantic bringing rains to the sunshine state and clouds with a few showers for the Ohio Valley into the Mid-Atlantic and New England.
Next week’s headliner wll be yet another powerful storm system that could once again bring accumulating snow to eastern Colorado, Tuesday/Wednesday and then spread colder air back into the eastern half of the U.S. for the latter part of next week.
