The Skiing Weatherman Conditions Report: February 6-9

Herb Stevens, GoLocalProv's Skiing Weatherman
I am going to start this post by getting right to the heart of the matter concerning the weather and snow conditions…we are now entering a period that could end up being the snowiest week of the season across the Northeast, and you should be making your plans to head for the hills. This week is getting underway with a narrow stripe of moderate to heavy snow across the northern Mid-Atlantic States, metro New York and southern New England. Anywhere from 4 to as much as 8 inches of snow will fall today (Monday), with Long Island and central New Jersey the sweet spot for the highest amounts. Now, that sort of distribution of snow only benefits a handful of ski areas, but I think this storm is only the appetizer…the main course and desert are on the way over the next 7 days. By this time next week, resorts from northern New Jersey to Maine will have anywhere from 18 to as much as 30 inches of new snow for you to play on.

How it’ll play out

The first system streaked out to sea southeast of Cape Cod on Monday. Yesterday one area of low pressure took shape over the northwestern Gulf of Mexico near the Texas coast, and then moved up just west of the Appalachians to a position near Pittsburgh by morning. Now it would be a bad track for snow lovers in the Northeast if it were to continue on up to the eastern Great Lakes, but because the upper support for that low will continue to pivot eastward toward the ocean, a second area of low pressure will form somewhere near the mouth of Chesapeake Bay.

The original low will weaken as it wanders up toward western New York, while the new low will feed off the relative warmth of the water and the upper support overhead, and become the primary circulation center for this event in the Northeast. This transfer of energy from an inland low to a coastal low is known as a Miller “B” storm, named after Air Force Colonel Robert Miller, whose research differentiated between two different scenarios that lead to storms on the East coast. Here is a map that shows you the general ideal of how a Miller “B” storm works…

The circled low over Tennessee is the original, or “primary” low, and the orange dashed lines which show a surface trough, roughly shows the track of that storm. But without the upper support, which continues to move toward the coast, the primary weakens and the “secondary”, which on this map is off the South Carolina coast, takes over and heads up the coast.

This time around, the secondary will have a good supply of cold air to work with over the Northeast, but it won’t be as deep or as cold as what we have seen the last couple of weeks. That will mean that coastal regions will see a mix of precipitation types from New York up to around Boston…north of there, even the coast will see snow. Because the storm will have it’s origin near the Gulf, this storm will be a juicy one, capable of producing heavy amounts of snow across much of the Northeast where it counts…in the hills. There is one factor that will limit the totals across far northern New England…the track of the storm will be off to the east-northeast, so amounts will taper down to 4 to 6 inches once you get north of roughly Route 2 in Maine and New Hampshire.

The Lincoln/Franconia Notch area, the North Conway region, as well as the mountains of western Maine up to Sunday River will pick up 6 to 10 inches; with 8 to 12 inches, falling from the Lakes region of New Hampshire southward to about the Mass Pike…Wachusett Mountain should be tagged with about 10-12 inches. Vermont will pick up substantial snow, as well, with 8-12 inches in the southern half of the state and 4 to 8 north of Route 4. The Berkshires are also in line for a solid 8-12 inches.

Looking ahead

In the wake of yesterday’s storm, a colder air mass will be drawn southward into the region, and the establishment of that colder air will set the stage for the next storm, which will also form near the Gulf before turning northeast for a run up the coast. The timing of the storm at this point appears to be later Saturday and Sunday, although that could change due to the fact that the upper air support for that system is somewhere up over Alaska as I write this post. It has a long way to go as it spins southeastward through the northern and central Rockies before producing the new surface system late this week. If you are about to make a trip to the Rockies, you will be happy to know that the upper level disturbance will produce some much needed snow in the West, too.

The weekend system looks like it will be a Miller “A” type storm, one whose primary comes up east of the Appalachians and continues up the coast toward the Maritimes. As a storm that comes from the Gulf breeding grounds, it should also be carrying a ton of moisture, and the potential exists for a snowfall that will be greater than what the midweek storm produces. Early indications are that the low will track more northeasterly than the midweek storm, so the far northern resorts should do better with the second event. Areas within 50 miles or so of the coast in southern New England could see a mix of snow and sleet at some point, but those areas should “net” snow. After that storm departs, the jet stream set up looks favorable for slightly colder than normal temperatures to be dominant through at least the middle of the month, which should sustain packed powder surface and set things up very nicely for the President’s Day holiday.

So, here comes a parade of storms that will produce multiple powder days, boost trail counts, cover some of the frozen granular spots that have been part of the landscape for a few weeks now, and build up base depths for the stretch run of the season. Arguably, the best run of snow conditions of the season is on the way…make your plans now.
