Weekend Snow for Oklahoma?

Been watching the GFS since Monday concerning the next storm system that will affect Oklahoma. It has flip flopped several runs temp-wise but has placed precip in Eastern OK by Sat evening. The flip flopping is what I'm having trouble with because the variable is surface temp! Will the precip fall as snow, ice or rain?

The NAM picked up on Saturday evening on the 06z run this morning, 84 hours out. Thus far, the NAM supports precip in the form of rain only, with temps hovering around 40.
I'll be watching future runs closely over the next few days for movement of that freezing line.

Seems the better set-up will be very late in the weekend and Monday when the truly cold air makes it this far south.

More later...
