Although New York City started May with five consecutive days of temperatures topping out at or above 80 degrees, temperatures since Sunday have left residents of the entire Great Lakes and Northeast wearing jackets and gloves and even some shoveling snow.
The warming effects of the rising sun angle in May are slow to occur the farther north you go, especially when you consider that Hudson Bay typically remains at least partially ice-covered into June. Such large bodies of water, or ice, contribute to cooling the air over eastern Canada.
The recent flow from the north and northwest has helped send some of cold air southward into the Great Lakes and Northeast.
The front that moved through last weekend delivered the first shot of cold and the locally damaging winds to settled well to the south allowing cold, dry cold air to pour southward out of Canada.
When this air comes southward into the Great Lakes and Northeast, temperatures typically stay well below normal. Add to this the cooling clouds and precipitation that have moved though the Great Lakes and Northeast yesterday and and it makes it feel even colder.
The flow from the north is set to relax this weekend and send allow milder air and dry weather to into most of the Northeast over the weekend.
It will not be in the 80s in New York City or Philadelphia over the weekend, but with some sunshine and temperatures in the 70s, it will be much nicer than the last few days.
