The computer models have come together on a low forming in the Ohio Valley and moving off the Atlantic coast on Friday. The models’ solutions now agree with putting the northeast corridor on the cold side of the storm. That gives us 3 to 6 inches, most near the coast and less inland. But stay tuned for updates – the impulse in the atmosphere that is forecast to generate our Friday storm is south of Alaska now. Modeled forecasts will get better when the wave reaches the Pacific coast of the USA, where it can be measured more frequently and more precisely.
In the meantime, we may get some small (but could briefly look impressive) snow showers Wednesday afternoon and evening.
