A complex cyclonic vortex has been bringing wintry weather across New England lately. A disturbance moving across the Great Lakes is forecast to intensify significantly as it traverses New England tonight into Wednesday. This will result in colder air to filter into the area, changing rain and freezing rain back to snow along with increasing winds from the north. Up to a foot of snow is possible across northern Maine by the time the storm moves further away into the Canadian Maritimes on Thursday. Colder air will usher into much of the eastern U.S. as the storm moves away and a high pressure ridge builds in from the Plains. Meanwhile, an active weather pattern over the Northeast Pacific will continue to bring energetic weather systems onshore across the West Coast. Wintry precipitation will once again move across the Intermountain region while rain is expected to continue along coastal Pacific Northwest into Thursday. The rain will extend as far south as Los Angeles, California Wednesday night. Over the central portion of the country, Chinook winds will bring a quick warm up across the northern High Plains on Thursday behind a warm front. Farther south, moisture will gradually gather across Texas, leading to increasing chance of rain to spread northeastward into Oklahoma by Thursday.
