After a pretty strong coastal storm hit yesterday with a quick 1-2 inches of rain we are right back on the storm train as a winter storm ,potentially a major one is brewing for the northeastern US starting late Wednesday lasting through Friday
Over the past several days model volatility for this storm has been extremely high but now that we are getting more sampled data from the disturbances and have our coastal low from yesterday forming a block over the North Atlantic the model guidance is trying better to reach consensus although still volatile model guidance the weather pattern looks to support a east coast storm
Today we have a cold front coming through the area and will have little disturbances and reinforcing cold shots through Thursday which should ensure that this storm is wintry for the area not wet meanwhile we have a northern stream disturbance in the northeast pacific coming towards the US and a sub tropical jet disturbance over Mexico both of which have potential to come together along the east coast and form a major storm
The details like snow amounts etc are impossible to tell this early in the game and for now we are just advertising that the threat for a long lasting winter storm is growing and there is potential for major snow accumulation for the forecast area between Thursday and Friday and also a brutal arctic shot there after with Friday being the coldest day possible in 5 years for many as highs will be stuck in the teens and lows anywhere from -5 NE PA to 5-10 degrees along the coast !
More details on the storm later in the coming days as we get new model data in to try to iron out specifics right now the area could see anywhere from a light to modest event to a major snowstorm.
