Cold air, winter weather returns to the forecast
Par for the course this winter, as one storm exits we are already looking ahead at another system which is modeled to potentially bring additional winter weather to the Northeast US. On the heels of a major winter storm for interior and northern New England, which brought a significant cold front and 30-40 degree temperature drop Thursday morning, forecast models are honing in on Pacific energy which will eject into the Southwest US later this week into the weekend. With a lobe of the Polar Vortex hanging around to our north providing cold air, any energetic or moisture filled disturbance would bring the potential for snow. The disturbance late this weekend could do exactly that.
Much of the forecast, however, hinges on the exact positioning and strength of the disturbance as it ejects northeastward from the Southwest US towards the Mid Atlantic. And not surprisingly, forecast models are up in arms as to exactly how consolidated the system will be as it does so. The Canadian, SREF and DGEX extension models all like the idea of the system ejecting as one consolidated trough with significant moisture, while the Euro and GFS are adamant in the idea that the system will be faster and split into multiple pieces.
