Things are shaping up for a potentially near-record lake effect snow event off the east ends of Lakes Erie and Ontario from tonight into Wednesday. Lapse rates will be steep with temps as low as -40C at 500mb above the still fairly-warm lakes. NWS Buffalo is expecting 3-5 inch-per-hour accumulations at times in the heaviest bands, and thundersnow is a good bet with this event. Some areas could see 2-3 feet, with another lake effect event likely coming quickly on the heels of this one late in the week. If I were located anywhere near this area, which I am not, I would be tempted to chase this. Just be well-prepared if you do, though, getting stuck in near-blizzard conditions is a definite possibility.
