Expect modifications of snowfall idea These early season storms are always a challenge, and this one is no different. Whereas in previous model runs, the upper level trough was more tilted, and the result of that was a more intense surface low, that does not appear to occur west of Penobscot Bay. Where my confidence is low is for eastern areas, as a result. The upper trough begins to tilt negatively, and a surface low forms along the cold front near Penobscot Bay, and intensifies heading into the Bay of Fundy. For the western half of the state, I am pretty confident with this snowfall map. The mountains should do well, which is great news for ski country. It's those hills which should receive the most accumulation. For the interior coastal plain and outskirts of the foothills, it's going to be a slushy mess. This is going to be a problem once it all freezes up as temperatures drop on Friday. Expect slick conditions not only for the duration of the storm, but also in to Friday night.  This loop runs from 1 AM Thursday to 1 AM Friday. Precipitation overspreads the region Thursday morning, then continues into Friday morning. Areas of rain may see some backside snow showers on Friday as the storm continues northeastward. I will update on the timing of this on Wednesday, and will make adjustments as necessary at that point.  Get your snow tires on!
