There is still a big cut-off with totals for areas south of I-70 because of a mix and even freezing rain.

Totals for Pittsburgh are near 6-8″ while areas north is in the 8-12″ range.

There is still a question how far north the warm air gets but that’s going to pose an ice threat of 0.1″ to .15″ of ice accumulation for areas south and east along the ridges for early Tuesday morning. It could take down totals significantly.

Another big thing is a refreeze Wednesday morning as lows look to drop near and in the single digits before we see the warmest day in a while on Thursday with highs in the mid to upper 30s but another wintry mix tracks through the region for the end of the week.
