Snow Tuesday Night?

On this rainy Monday, our attention is already turning to the next system that will impact our weather, from Tuesday night through Wednesday.  Today’s moisture is falling entirely as rain, but things are looking a bit more complicated by tomorrow night.  If you’re a snow-lover, don’t get too excited…if you’re a snow-hater, don’t get too worried.  This looks like a minimal snow-maker for most of us — the exception to that is in the “usual spots” in eastern Middle Tennessee.

Before the rain-to-snow showers arrive, we’ll have to contend with some locally dense fog Tuesday morning…that’s the dim gray area shown on this Futurecast image:

The fog will burn off by between 9-10am, and we’ll see quite a bit of sunshine through early afternoon.  That’s temporary, though…by late afternoon, clouds will thicken, and we’ll see rain showers moving in around sunset.  These three images show the progress of those showers between 4:00pm and 8:00pm Tuesday:

RPM 6P TUE
RPM 8P TUE

As the showers move east, cold air will move in.  The cold air will catch up to the showers, leading to a mix of rain and snow, and eventually snow in eastern Middle Tennessee:

RPM 12A WED

Notice how “confined” the snow is in those images — accumulations just aren’t likely across most of the Midstate, including the Nashville Metro.  But that doesn’t mean Nashville will be completely snow-free…by Wednesday morning, the atmosphere will be squeezing out a few bursts of flurries and light snow:

Those little bursts of snow will only add up to a dusting for most of us: a thin layer of flakes, mostly on lawns and rooftops.  The Cumberland Plateau and eastern Highland Rim will, as usual, have the best chance to pick up measurable accumulations:

The National Weather Service is thinking along similar lines, although at this point they’re slightly more snow-optimistic:

Plenty of cold air will flow in behind this minor snow-maker.  Another chance of flurries will head our way Friday, but right now that’s looking even less impressive than Tuesday night and Wednesday’s snow chance.

Bottom line: yes, some of us will get snow. No, it won’t amount to much.  So don’t…well, you know:
freaking-out
