Update on November 14: Cold Snap to continue in USA
On the heels of last winter storm the potential for snow is there on Saturday till Monday for a large part of the Plains, Midwest, and at least interior Northeast. For some locations, it may be the first accumulating snow of the season.
Forecast
15 Nov: A broad area of snow will spread across the central Plains, Missouri Valley and mid-Mississippi Valley, spreading to the Great Lakes Saturday evening. A second area of snow will plunge southward from central Rockies and Plains.
16 Nov: An expansive area of light snow may fall from parts of the southern Plains to the Ohio Valley and northern New England.
17 Nov: A stripe of snow may fall on the backside of advancing, reinforcing cold front in parts of the Ohio Valley and interior Northeast.
While not a widespread threat at this time, we can't rule out some patchy areas of sleet and/or freezing rain along the southern edge of the precipitation from the southern Plains to parts of Tennessee and Kentucky.
Early Snow in South!
There already have been two unusually early snows in the South: the post-Halloween event in parts of South Carolina and the southern Appalachians, and some light snow that streaked across the Mid-South on Thursday.
Update on November 13: Arctic cold wave to last till next week
The ongoing Arctic outbreak pattern is considered to be a classic pattern that will remain largely locked in over US for at least the initial half of the next week, before easing a bit, later next week.
Maximum temperatures are expected to be in teens or 20s around the week over northern Rockies, northern Plains and Upper Midwest. With fresh snow over the areas of the northern Rockies and High Plains, we are expecting subzero cool, which will be most widespread in these areas.
Moreover, the temperatures in some of the areas that received heavy snow from Winter Storm Astro in the northern Plains and Upper Midwest may also dip below zero later in the week. The arctic surges will also sweep into parts of the East.
Update on November 12: Polar air invasion continues across USA
After having snow in Midwest over the weekend, a potent burst of Arctic air is plunging into Midwest and area down the South into cold frenzy. This will result in drop in temperatures down to the values during mid winters.
Temperatures had fallen by 20 to 30°F in less than one hour. Four people were reported to be dead in separate incidences in Minnesota.
According to Skymet Meteorology Division in India, sub-zero temperatures are also likely across the states at various time during next week.
Update on November 11: Heavy Snow in Dakotas, Minnesota, Michigan & Wisconsin
Due to a potent arctic outbreak, parts of the Upper Midwest and Plains are seeing their first heavy snow of the season. In a few cases, records have been set. A winter storm is well on its way, and by the time it winds down early Wednesday, it will have put down a swath of heavy snow from Montana to Michigan.
The winter storm that broke out on Sunday as predicted by Skymet weather division brought bountiful snowfall in eastern Wyoming, across South Dakota to southern Minnesota/southern Wisconsin/and parts of Michigan and extreme northern Illinois. The places which recorded major snowfall are:-
- Bismarck, North Dakota 3.2 inches
- South and East Montana 9 inches (Glasgow 6 inches) – highest in Big Mountain Summit 14 inches
- Webster, South Dakota 8 inches
- West and East Minnesota 12 inches – highest St. Augusta 16.5 inches
- Wisconsin 14 inches
- Michigan 12 inches
- Wyoming 11 inches at Cloud Peak Reservoir and Grand Targhee,
- Colorado: 6.0 inches near Phippsburg in northwest Colorado.
- North Dakota: 7.5 inches at Marmarth in southwest North Dakota.
The winter storm and snow will continue till Wednesday.
Update on November 10: Heavy snow and wind is all set to lash northern Maine and far Northern New England by overnight. A low pressure system then forms off the New England coast and deepens rapidly under the support of an upper level jet stream. As the surface low moves northeast off the New England, it circulates a burst of moisture back across inland Maine and far northern New England. Coastal locations will be too warm for snowfall but inland as much as 8 to 12 inches of snow is likely including Caribou where record snows occurred just last weekend.
Caribou has already seen nearly a foot of snow in November so far, more than the typical snowfall for the entire month. If another foot occurs, it will be more than double their normal snowfall for the entire month.
Update on November 9: Polar Air likely to interlude across the U.S. in coming week
Computer models indicate that the atmosphere will set up to produce another arctic outbreak across the eastern U.S. this weekend and into the next week. The first blast of colder air came by Saturday, which led to drop in temperatures by some 10 to 15 degrees below normal across the East. The second system brings an even colder blast of arctic air from the Upper Midwest through much of the East in the Monday through Wednesday time frame with temperatures reducing as much as 20 degrees colder than normal across the Appalachians.
There is the potential to develop snow/ice near the arctic boundary that is laid down across the east next week.
Snow begins on Sunday
Snow starts by late Sunday over parts of Montana/Wyoming and it will spread eastward to the northern Plains/Upper Midwest and parts of the Great Lakes. A band of snow will develop from eastern Wyoming, across South Dakota to southern Minnesota/southern Wisconsin/northern Iowa/and parts of Michigan and extreme northern Illinois.
All of this will stem from an interaction of a wave of low pressure and the southward push of an arctic cold front
