THe first one comes in this afternoon with some lake enhancement 

to the light synoptic snows and a general 1 to 2 inches by the 

time the snow tapers off after midnight. 



Snow will flare up again as the next shortwave trough follows 

quickly for Wednesday. Expect another 1 to 2 inches by Thursday 

morning before the trough axis moves east and heights rise. Light 

lake effect snow showers are possible on Friday as weak shortwave 

troughing occurs, but additional accumulations are not expected.
