A rather weak, short duration system will scoot across New England overnight tonight, with the center passing inside the benchmark, near Cape Cod. This will bring a quick shot of rain to southern New England and the northern New England coastal plain with snow across the interior. The main storm system will dart from around Kentucky Wednesday morning to around Nova Scotia by Thursday morning.
Precipitation is expected to break out Wednesday evening across western New England and steadily push east through the first part of Wednesday night. Initial precipitation may be rain or a mix for most in the evening before transitioning to snow from north to south and high elevations to lower elevations.
Below: NAM showing potential weather this evening:
By Wednesday night, a steady snow will likely be falling across much of interior northern New England with rain elsewhere. The rain/snow line will try to inch southward through the night. The storm will wrap up as quickly as it started, shutting down from west to east through Thursday morning. By midday, only scattered upslope snow showers will likely remain.
