1) Wednesday - Snow will start after 2am Wednesday, and fall at a light to moderate clip through dawn. Accumulations of 1 - 2 inches can be expected by 6am. As mid level temperatures warm, snow may begin mixing with sleet late Wednesday morning before tapering off Wednesday afternoon. Total accumulations of 3 to 5 inches can be expected. >The exact timing of the event will dictate if a delay or cancellation is needed. For a cancellation, an couple more inches would be required. At this point, with the peak of the event possibly occuring during the morning commute, a delay may be necessary.<

2) Friday - A much stronger system will move towards the region Thursday Night. Temperature profiles indicate this could be snow for most of the region at least in the beginning. Significant accumulations appear likely at this time. Currently thinking 5 to 9 inches is possible. >The timing of the event will be centered during the day Friday, so a cancellation is looking promising at this time.<

3) Monday (22) - A strong storm system will cut north to the Great Lakes region, while high pressure remains intact to our north. Secondary low pressure may develop to the south of the region. The GFS and ECMWF both advertise a very intense storm with heavy precipitation and strong winds. At this time, it looks like mainly snow north of the Mass Pike. In that case, we would be talking about another 6+" easily.

So, a busy 7 days ahead of us. Stay tuned.
