Midday...

Had enough snow with sleet mixed in to dust the ground in much of the I-85 corridor in Cleveland, Gaston, and into Meck county and the surrounding areas. Radar doesn't look terribly promising for anything north and west of I-85 in the Triad, and frankly, the precip looks to be pretty short lived in the Triad viewing area where it does occur.


Watch the radars....this event will wind down from west to east, and that will be about it for this event. Doesn't look like there is much opportunity for any further development after the current wave. So, folks that saw something....enjoy! Folks that didn't....let's look for the next one.

Saturday Morning....

Good morning! Wanted to put up a quick post about what remains a pretty low-confidence forecast.


It looks like a good portion of the region will see at least light precip move through at some point today. The total amounts of precip with this one look pretty low overall until you get down into central and eastern SC and eastern and SE NC.

For the Charlotte area, looks like I am just going to have to go with the wording of a light wintry mix today....the mix being rain, sleet, and snow. A lot of the precip types will depend on precip rates. Temps are tricky....the area is in the 30s now, and I question exactly how much warming can take place.

This evening, there could be a final push of some light to moderate snow pivot through the region, and I suppose some places could pick up some minor accumulations.

For the Triad, same general idea, although there might be less rain in the equation. There is a little better chance of picking up some small accumulations in this area, especially as we head into later this afternoon/ evening.

The winter weather advisory for the Triangle put out by the Raleigh NWS is probably placed well. I still suppose the Triangle area has the highest potential of picking up some accumulations with this.

Also note there is the potential for a short-fused winter weather advisory to be popped out about anywhere around the region as we see how the precip shield will develop.

**Just laying the cards all out on the table here....this is about as low a confidence forecast as I have put out in recent memory. I have very little confidence on where the heaviest precip areas will set up, not to mention what the exact thermal profile will be. When you are dealing with a degree or so difference at 3,000 to 5,000 feet in elevation determining precip types, and in situations like these, the rate of precip plays a big role, saying it is a challenge is an understatement. But I guess that is what makes it fun. This system has been a booger from the word 'go.'

With all of that said, this is not a huge winter storm, and many people will not see any type of accumulation at all. But it sure is fun to watch.

Friday afternoon...

The 12z models have not shown any more amplification with the weekend system....in fact, some show less.


I will continue with the same ideas I had on air this morning. Please see the map in the previous post below. The best chance of seeing some flakes lies between I-85 and I-95 starting northeast of Charlotte, and the best chance of seeing accumulations is from around the Triangle up into southeastern VA.

It just appears the system will not amplify enough to spread precip back into the foothills or much of the western Piedmont.

Again, see the map below for the best zone of seeing a few flakes tomorrow evening.

Standard disclaimer....there is always the chance of a last-minute northwest trend. However, I saw no indication of that as of the 12z models.

**The 18z NAM has come in with a more amplified system and QPF pulled farther west. Then again, it is the 18z NAM. We will see what 0z holds tonight.**
