There are opportunities for snow this week and they include the Upper Midwest, northern New England and neighboring Canada.
Last week snow fell on parts of the northern Plains, Denver and Cheyenne and barely reached the highest elevations of the Northeast late this past weekend.
This week, cold air will continue to nose southward from the polar regions and will try to hook up with weak storm systems along the Canada/United States border in two separate events. The pattern will extend the chance of the first snowflakes of the season to some northern tier locations.
While temperatures will be marginal in both cases, a few degrees can make the difference between all rain and wet snow mixing in for a time.
As a disturbance and surface cold front swing across the Great Lakes, some wet snowflakes can make an appearance in portions of Wisconsin, upper and northern lower Michigan and central Ontario Wednesday. A second disturbance could bring another opportunity Wednesday night into Thursday evening. Cities that may get a little snow include Duluth, Minn. and Marquette, Mich., and Thunder Bay, Ont. A few snowflakes could reach as far south as Green Bay, Wis., and Traverse City, Mich.
The first of the two systems are then forecast to move on to northern upstate New York, Vermont, northern New Hampshire, northern and western Maine, and portions of Quebec Wednesday night. There is a chance of rain mixing with or changing to a little wet snow before ending. The second disturbance would swing through Thursday night with the chance of a rain/snow mix or a period of snow. Cities that have a chance at getting a little snow from one or both systems include Ottawa, Montreal and Quebec City. Snowflakes could reach as far south as low elevation locations such as Massena, N.Y, Burlington, Vt., and Caribou Maine. A little snow is more likely over the mountains northern New England, southern Quebec and the peaks in the Adirondacks.
According to Expert Senior Meteorologist Brett Anderson, "In both cases in both areas, the second of the two disturbances may have a little more cold air established to work with. So the second system has a slightly greater chance at allowing snow to reach the ground in more places."
In the wake of the potential for a touch of snow for northern areas, the coldest air of the season so far will spread a killing frost and freeze farther east than any such air mass so far this autumn. The upcoming frost and freeze can reach the I-95 corridor of the Northeast.
Elsewhere, a little more snow was spreading southward over the foothills, eastern slopes of the Rockies and some of the High Plains in Alberta and eastern British Columbia Wednesday.
A storm rolling into California this week may, by this weekend, could bring heavy high country snow to portions of Colorado, northern New Mexico and Utah's Wasatch Mountains.
Several storms will bring periods of rain and gusty winds to the west coast of the United States next week with the potential for one of these to reach Southern California.
Colder weather, and in some cases, a taste of winter with snow will continue to invade the northeastern United States this weekend.
Dry weather set to dominate the southern United States into November will only worsen the already extreme drought conditions.
The changing of the seasons will bring beneficial rainfall to northern Brazil, a region that has experienced severe drought over the past several years.
Damaging storms pounded the Pacific Northwest, while two powerful typhoons struck the Philippines within a four-day span.
