11/24 - 4pm - Something Could Be Lurking in the Models

My rain gauge reads .66" of rain since midnight, which seems reasonable given how heavy the rain was early this morning. The good news is that it's out of here, but unfortunately temperatures will stay in the 40's for the remainder of the week. Tomorrow will be the coldest day, with a high that will struggle to reach 40. A high of 50 is not out of the question for Thanksgiving, but it's difficult to tell what might happen this weekend temperature-wise.

What I mean is that some of the models are showing a snowstorm for this Friday and into the weekend. The GFS is really not picking up on this and suppressing the associated low to the south. It also shows warmer air in here that the other models do not favor. The Canadian in particular has the low tracking south of us and then cutting up through Eastern Kentucky, which would be a classic snow solution for us. The DGEX is a little more aggressive with the cold air and precipitation than the GFS, but still nowhere near models like the Canadian.

At this point we just need to sit back and wait. I'd say the chances of a storm actually playing out this weekend are fairly small, but a little snow on the backside of a rain system would make more sense to me. The Louisville NWS isn't jumping on any bandwagon and calling for mostly rain with a possible period of snow or mix if the models trend colder. I think that's a pretty sound forecast given the great uncertainty, so I'll go with that for now.
