Equilibrium levels up around 20k! There will be a brief break in the rain following the cold front. Later Wednesday afternoon and Wednesday night deeper wrap around moisture will arrive as the strong mid level closed low crosses the eastern Great Lakes and heads into New England. The wrap around moisture and forcing from the mid level trough will produce a few scattered showers Wednesday night. More importantly, deepening cold air will support growing lake induced instability. Flow may be sheared initially, but should align better from the WNW later Wednesday night as lake induced equilibrium levels rise to 15-20K feet. This will support a robust lake response east and southeast of the lakes, with rain showers becoming widespread. Deep moisture and lift extending up through the graupel growth zone may support some thunder as well.

Anyone keeping an eye on this potent Miller B Nor'Easter this week? Latest runs have the secondary low bombing to 971 just off the coast of Maine. Looks like a couple of very raw, rainy, and windy days on tap for us. Before it transitions we get a hefty thump of rain too. i think the highest peaks of New Hampshire and Vermont might get some significant snows. It's fun to have some active weather to track. We are officially into "interesting weather mode" for the next 7 months.

Looked back at my weather journal and just last year Rochester had a coating of snow on the 18th of October with several other days around that time having flakes in the air.

Denver was 82 degrees at 3pm yesterday and was 21 degrees by 6am this morning. A 61 degree drop in 15 hours. Thats intense!
