Discussion
A strong “clipper” system will drop southeastward into the Mid-Atlantic region today and it’ll feature some rather cold air in the upper part of the atmosphere. At the same time, the southern storm that soaked the southern states in recent days will intensify after it moves out over the open waters of the western Atlantic. In fact, this storm could intensify to a point where it is produces hurricane-force winds by tonight in the western Atlantic. While this ocean storm will be situated well off the east coast, it’ll still have an influence in the Mid-Atlantic region as an inverted trough (aka “norlun” trough) will extend from the low pressure center all the way back to the Mid-Atlantic. The combination of the “clipper” system and the inverted trough associated with the ocean storm is going to lead to rain and/or snow showers in the NYC metro region later today and tonight. In some “norlun” trough scenarios, small-scale heavier bands of precipitation can form and we’ll have to closely monitor that possibility late today and tonight; especially, across eastern PA and New Jersey. Following today’s mess, the weekend will start off on the chilly and dry side, but a major warm up will take place early next week. In fact, the weather on Monday should feature sunshine and warmth with temperatures well up in the 60’s for afternoon highs.
