Discussion

A remarkable cold air outbreak is coming to the region for Friday night and Saturday and it will be accompanied by a rain-changing-to-snow event in many interior sections of the Mid-Atlantic/Northeast US. The weather will become quite a bit more active later today as a strong cold front advances this way from the Upper Midwest and low pressure begins to develop over the Tennessee Valley. This low pressure system will push along the southeastward-advancing cold frontal boundary zone and rain is likely to return to the region during the afternoon and evening hours. As colder air wraps into the system tonight, the rain is likely to change to snow in a good part of the Mid-Atlantic/Northeast US; especially, across interior higher elevation locations of upstate PA, NY and New England where accumulations are possible. In fact, there can be a changeover from rain-to-snow showers later tonight all the way into the suburban locations just to the north and west of metro region. This low pressure system will intensify dramatically by the time it reaches the Gulf of Maine on and a deepening pressure gradient will result in powerful winds to go along with the unusual cold. Winds on Saturday can gust to 50 mph or so raising the chance for scattered power outages. Looking ahead, the overall weather pattern that has resulted in multiple cold air outbreaks from Canada into the central and eastern US during the past several weeks is likely to finally break down during the third week of May, but we’ll have to endure some pain before we get to those expected warmer-than-normal conditions.
