Rain will be the main story with this storm as the westerly track will put most on the warm side of the low. Accumulations of 2-5" will be possible region wide with the bulls eye being over central CT. Minor street flooding could become an issue especially in CT where the heaviest rain will be focused. Rain will begin late Tuesday night over southern areas spreading northward through Tuesday night. Rain will become heavy at times Wednesday as the low intensifies. If you're travelling Wednesday, expect slow going on interstates 95, 93, and 89 due to wet conditions.
Snow will be confined to far NW VT, upstate NY, PA, OH, and the mountains of the Southern Appalachians. Snow amounts could be quite hefty in areas where lake effect off the northwest winds behind the storm could add to totals. Amounts on the order of 3-6" will be most common though lake effect zones could see upwards of 8".
Winds will strengthen out of the southwest tomorrow in anticipation of the storm. This will bring in warmer air resulting in the precipitation being mostly rain. On Wednesday, winds will become very strong out of the SW gusting close to 50 or 55 mph by evening. This combined with the saturated ground will likely cause power outage problems. Winds will turn gusty out of the NW on Thanksgiving ushering in bitter temps for those crazy enough to line up outside of stores before black Friday.
I'll have another update tonight if the forecast drastically changes, otherwise I'll be back tomorrow.
