Short term:
Looking at the 00Z and 06Z GFS model run with support form the ECMWF there is another piece of short wave energy in the 500 mb flow that developes a bit of a frontal wave that appears Thursday night over Western Pennsylvania. If this verifies, while it may slow up the cold air advection further east, it also has a chance of providing snow across Northern Indiana and Southern Michigan into Northwest Ohio.
Long term:
The CMC operational run with ensemble support shows a big ridge building in the PNA position in about 10 days. A 558dcm ridge (actually showing up as 576 dcm on some charts) teleconnecting with a 486dcm Canadian low a little further north then the classic Hudson Bay position. This is to a point somewhat maintained through another week which is how far out the model goes out. However there is no support here from the Operational GFS but some of its ensemble members do show this to soem extent. This may change with the next model run but it is something at this point in time worthy of another look.
