A mixed bag is expected today as we have lake snows moving over northern and east central Indiana today, but nothing major in other areas. Clouds will dominate, and after yesterday’s mild push over the southern part of the state, we see temps moving back down. Low pressure is interacting with lake winds to produce the snows today, with the best snows stretching from SW Lower Michigan down to east central Indiana and west central Ohio. We can see several inches of accumulation in the north and east.
A stronger clipper system is in for the area tomorrow. The best snows develop late morning and early afternoon on through the overnight. We can see 1-4 inches over the northern half to third of the state and into Ohio. This will be a fairly significant event. However, areas in SW Indiana and southern Indiana we see little to no action
Thursday and Friday should be mostly dry with no frontal action moving in. But we continue to see some on and off light snow action around in northern Indiana, fueled by lake effect breezes through the period. Saturday looks like another “north vs. south” kind of day, with snows in the morning north of US 30, but nothing farther south. Another low pressure circulation moves in for Sunday, and we have to put precipitation in the forecast to finish the weekend. Snow totals can be 2-4 inches over the northern half of the state, with 100% coverage north of US 24. Once again, south of I-70, we have nothing. This is the system we had been watching for Sunday night and Monday. The low is pushing farther north, keeping precipitation out of southern Indiana and it is coming faster.
We should be a little drier for next week, then, Monday through Wednesday. Temps remain normal to slightly below. While we do see a large part of the state trying to climb above freezing, we do not see as strong of southwest flow now and think that any bump in temperatures will be minor. Lake snows and strong north winds are back by Thursday, and temps head back down.
The extended period still shows plenty of cold air, and we look for snows around the 21st into the 22nd. There should be good coverage over the state, but the question remains concerning any liquid that may try to mix in. Behind that, we are dry through Christmas weekend, with snow trying to develop out of an upper level low coming through the great lakes Christmas night into the 26th.
