More Arctic Air in Store from Upper Midwest to New England

Air just north of Great Lakes is colder than that over the North Pole

Cold weather will stick around through the weekend from the Upper Midwest to the mid-Atlantic and New England.

The bitterly cold air will slosh out by the end of the week and will not dip into the Deep South.

Moderate cold (lower-than-average temperatures) will remain in place into Sunday in most areas farther north.

According to Expert Senior Meteorologist Henry Margusity, "The coldest air mass in North America was sitting just north of the Great Lakes over central and northern Ontario and western and central Quebec Tuesday morning."

Temperatures reached the 40-below-zero mark in these areas and dipped below zero from northern New England to much of Michigan and areas near and north of Chicago.

AccuWeather.com Staff Writer Grace Muller has some statistics on the cold.

"The air just north of the Great Lakes is colder than that over the North Pole," Margusity said.

The arctic outbreak is the end result of the stratospheric warming discussed a couple of weeks ago on AccuWeather.com. The cold pattern delivered by this stratospheric event generally lasts a couple of weeks to a couple of months.

Temperatures have already or will approach levels not reached in the past two to four years in a number of locations by the middle of the week from the Upper Midwest into the Northeast. In some cases, these levels are represented by daytime highs, and in others they are represented by overnight lows.

It's Not Storm-Free Cold

The pattern is bringing snow to more places than just downwind of the Great Lakes.

The southward plunge in steering-level winds high in the atmosphere, known as the jet stream, is guiding a series of storms from western Canada and across the northeastern third of the nation. These storms, known as Alberta Clippers, can bring anything from spotty flurries to a heavy snowfall.

A weak Alberta Clipper may bring spotty flurries to perhaps a coating of snow across part of southern Ohio to northern Virginia, Maryland, part of the Delmarva Peninsula, southern Pennsylvania and southern New Jersey late Wednesday night into Thursday morning.

A stronger clipper that may merge with a more southern storm has the potential to bring a swath of moderate to heavy snow from portions of the Ohio Valley to part of the mid-Atlantic coast Friday and possibly part of New England Friday night into Saturday. This storm is trending colder and farther south with its all-snow area.

Next Week and Beyond

The cold is forecast to relax next week. However, the extent of this relaxation is questionable.
The latest indications are that a storm riding the crest of the warmth during the middle of the week may track farther east, rather than north. If this happens, lingering cold air near the surface could set up a large zone of a wintry mix or ice in the Midwest and Northeast.

Regardless of that major storm track next week, AccuWeather.com's Long Range Team of meteorologists expect arctic air to return in the wake of the storm during early February.

According to Expert Senior Meteorologist Paul Pastelok, "Additional waves of cold air are likely to yield below-average temperatures for the end result of February from the Upper Midwest to the Carolinas on north."

Pastelok added that the temperature departures during the first part of February will outweigh moderating temperatures later during the same month.

It is currently **02** F as in just TWO degrees in my own New England town, in northeastern MA, with a low of -03*F predicted for tomorrow (tonight).. yowza! As a lifelong resident of this area, it's been a while since it got THAT low indeed XD which is way colder than it should ever be (rather, 30s & 40s are a more normal winter); altho since I'm personally most comfortable with temps btwn the low/mid-50s to upper 60s / low 70s, I'm still not in any rush for summer, hehe. I'll choose freezing cold temps over boiling hot ones every time! ;P

The science is clear and there is not substantial disagreement among experts. You deniers seem to have a problem identifying the difference between weather and climate.

It's cold because it is January. What about the radiation from the Fukushima Power Plant
in Japan. Is the Radiation riding the arctic jetstream and laying an obscene blanket across
our nation?

If Hamilton, Ontario is colder than the North Pole that proves the climate has changed. Might not the warm temperatures at the North Pole also be caused by the presence of huge areas of open water where the ice used to be.? For someone calling others idiots you don't seem to have this thing very well thought out.
