Good evening, everyone. Rain is getting ready to develop and roll our way, but the focus is on a big temp drop and the potential for some Tuesday into Tuesday night. The exact location of a swath of accumulating snow is still to be determined. πŸ™‚

I have no changes to my earlier map for the best snowfall odds…

Some of the late afternoon guidance shifted quite a bit farther to the west, but a few other models held tight to a more eastern and southeastern event. I really don’t like the 18z runs of any particular model on any given day because they seem to be more jumpy than the typical 0z or 12z runs.

Still, they can sniff out trends and that’s what we will be watching for on the 0z runs that will start shortly.

Here’s a sampling of the 18z runs of the models…

We are now within the 48 hour window, but I would like to see better model agreement before putting out a First Call Map. Here’s hoping we see that with the next round of runs.

I will have all that in my next update later tonight. Have a good one and take care.
