A Few Flakes Tonight - Eyes on The Horizon

Tonight we will see rain showers changing to or mixed with snow. I don't foresee anything more than minor accumulation (<1/2") on grassy/raised surfaces - so put your snow shovel up for the moment.


However...next Tuesday brings a much better shot of accumulating snow in the Piedmont of NC. How much - impossible to say at the moment...

Synoptic situation - expecting a trough to move east/south across the plain states and then form a surface low near the GOM that will move NE to a point off the coast of NC. Much like our previous storm but lacking the northern branch feature that really made the low "bomb" as it headed up the coast.

Here are two shots from the GFS. #1 is the 500mb feature and #2 shows the surface feature(s) @ 150 hours. As always, this is almost a week away so it is bound to change.
