Another interesting smaller event--

This winter-- UGG.

Larger events can be a challenge, but there is a sense of ease because you know what you have it's just the finer details of rain/snow and amounts. This year, we've had so many smaller events-- per example last Saturday's events where some of the model data hinted of a stronger band and sure enough it happened. (smaller then modeled, but that's expected because of model resolution)

Here, we've got a storm dying over the Midwest and some moisture pushing on the east side of this low SMACK DAB into very dry air. Dry air, that often just dries this stuff up. Next, we have second wave coming through late Friday into Saturday and cold air, just cold enough lingering around.

1. Don't fret temps-- this air is colder and drier than Monday's fiasco. Temps are near 40, but they will drop a degree or two and before precip starts and then tumble quickly down to near freezing, bottoming out in the upper 20's.

2. I'm still not sure where this is going.

Short term models have the heavier stuff going to our south-- closer to the NC/VA border with even maybe a quick 2-3 inches before it changes.

The GFS/ECMWF (Euro) are much drier and maybe give us .15  or so before noon tomorrow that starts as snow and ends as freezing drizzle.

The NAM which is ALWAYS too wet-- has almost 2 inches of snow in our region.

Meh--

I think that snow and sleet breaks out after midnight west and between 2-4 east. It may mix with sleet at first, kick to all snow and then transition back to sleet and then eventually freezing rain.

Amounts-- Coating to 2 inches snow and sleet. Best snow amounts NORTH of 460. (Closer to two inches)

Most schools and stuff cancelled tomorrow.

Snow through mid morning and sleet through 1 PM or so-- sooner the more South and West you go.

BTW, Blacksburg is on Facebook and here is their snow map.. I think their map is a bit cluttered, but conveys the general idea. You should follow them.
