Then -- just to give you a heads-up -- five days after record-breaking temperatures, we could see our first winter storm.

“We’re watching the potential for our first accumulating snow this coming Tuesday,” says Bill Potter of Hudson Valley Weather. “How on earth is this possible? Well… the jet stream is very active right now, and in the wake of the storm this weekend, it could buckle just enough to allow some arctic air to filter into the Hudson Valley on Monday. Then… as soon as the arctic air settles in… a storm system could approach from the southwest and throw moisture over top of the cold air. If that happens… we could see a period of snow, mixing with sleet and freezing rain… ending as a plain cold rain.

“There are a lot of “ifs” here… with details being critically important. Likely most important, will be the exact location of the arctic high pressure, that will supply the cold blast of air.”
