Cold northwesterly flow is expected to maintain snow chances in lee of the Lakes and in the higher terrain through Wednesday, but conditions thereafter will be of improvement as building high pressure drys and warms the weather in advance of another Wrn CONUS trough. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... The advance and passage of the aforementioned trough is timed to degrade conditions via rain for the weekend, and cool temperature back toward the average for the start of the new week. && .AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
