Mid-afternoon update....

A tornado watch has been issued for a good chunk of SC up into the Charlotte metro region of NC. The wedge has been successfully eroded away for most of the Piedmont, and the airmass is slowly getting more unstable. Most temps were in the 60s, and so were the dewpoints as of 2-3pm.

The sun is out in parts of GA up into parts of southern SC, and the airmass is rapidly getting more unstable there. Some of that unstable air will get pulled northward in the southerly flow ahead of the system.

The main band of rain and embedded storms will progress through the mountains and emerge into the foothills by early this evening.

Don't let the radar deceive you. The activity will probably not look terribly impressive as it begins to emerge out of the higher elevations. However, as the incoming dynamics interact with the more unstable air in the Piedmont and Upstate, the storms will likely intensify.

Damaging winds and a few tornadoes are the concern this evening into tonight.

Stay with News 14 Carolina on television for all of the latest information. And tonight is a perfect example of every home needing a NOAA weather radio.

Powerhouse system moving in...

Below is today's edition of the video...



The region will continue to see periods of rain today as a major storm system crawls into the area. The cool conditions we had in place yesterday will give way to a much milder airmass in time today, and most of the Piedmont will be well up into the 60s by later this afternoon. Some spots could even hit 70 degrees or so.

As the airmass gets more unstable, thunderstorms enter the forecast equation. While a few storms could be involved late this afternoon, I think tonight is the main time-frame for storms. This is a classic high shear/ low instability setup, and similar setups in the past have resulted in severe weather. We will have to be vigilant in watching for severe storms capable of producing damaging winds and even a few tornadoes tonight.

This is another case where the possibility exists over severe weather while the bulk of the community is sleeping. Every home should have a NOAA weather radio. If and when severe weather develops, we will be on the air covering it for you, but we can't wake you up through the TV sets. There is a chance this winds up being a non-event, but have a way of hearing watches and warnings in the event they are required.

Quiet and chilly weather resumes tomorrow through the weekend. A 'clipper' system will roll through Sunday and bring some clouds. However, the moisture still looks quite limited, and once again I have left precip out of the weekend forecast. Most high and low temps on a daily basis will be a little below average.

Next week...

Model madness continues for next week, and I still think there is the possibility of a storm system for the Deep South and/or Southeast Tuesday into Wednesday. I think the GFS is unusable for the time being (at least as of the 0z run today)....it over-amplifies things early next week over the eastern US and really crushes the disturbance that would create the storm system. The Canadian and European models both still have the system, and I think they are more correct. But time will tell....

Dynamic storm system on the way. . .



After some fairly chilly, docile weather Saturday and Sunday, the weather is about to get more active around here. Today, clouds will be on the increase for the Charlotte and Triad zones on up into the mountains, and some drizzle could develop in time. Highs today will largely be in the upper 40s to lower 50s.

The core of our next system will swing through later tomorrow and exit very early Wednesday. Rain will be a possibility from time to time tomorrow, with the heaviest rain during the day being the farther west you head....especially in the mountains and foothills. With time, the band of heavier rain will pivot eastward through the rest of the area. This will occur mainly Tuesday night. at that point, a few storms could be involved as well. This is a high shear/ low instability set up, and a few severe storms can't be ruled out, especially as you get closer to I-95.

Flooding will likely be an issue for the mountains and foothills. I fully anticipate some 3-5" rain amounts in those areas. For the I-85 corridor, this is looking like a 1-2" type rain event.

Later this week...

A fresh push of cold air will arrive later Wednesday, and highs will likely struggle to get out of the 40s in some Piedmont spots Thursday into the weekend.

A couple of 'clipper' type systems will move through late this week and then again Sunday. At this point, moisture looks pretty limited, so I don't have any precip chances in the forecast with those.

System next week...

It sure looks like another system will roll through the region Tuesday or Wednesday of next week. This is the one that has been hinted at by the modeling for a while now. That one definitely bears watching for the potential for at least some wintry weather somewhere around the region as a whole. WAY too soon for any type of details....but it has my interest.

Cold front moving through today...

Black Friday began in mild, breezy fashion with Piedmont temps surging up into the 60s ahead of an advancing cold front. That front will continues to move through the region today, and we will continue to have the chance of some showers into this afternoon. A few rumbles of thunder can't be ruled out, but there is not enough instability in place for a big worry with thunderstorms.

Temperatures will begin to drop this afternoon, and by the time Saturday morning arrives, most spots will be below freezing.

Sunshine will abound tomorrow and Sunday with highs in the 50s. Lows will remain below freezing through Monday morning.

Next system...

Our next storm system will roll through Tuesday and Wednesday next week. Look for shower chances both days, and some storms look like a possibility Tuesday night into early Wednesday.

Much colder air will flow in here later Wednesday, and the rain could change to snow up in the mountains prior to ending. We will have another chilly, primarily sunny couple of days to finish next week.

Happy Thanksgiving!

I want to wish everyone a happy Thanksgiving!

In terms of the weather....no the prettiest of Thanksgiving forecasts. We have somewhat of a cold air damming scenario in play today. The result is a lot of clouds and fairly cool temps. Piedmont highs will range from the mid 50s to lower 60s, and some light rain and drizzle is possible at times.

The wedge will get scoured out tonight, and that will mean steady or even rising temps.

Tomorrow, a cold front will slide through, and that front will bring some showers. So, as you head out to hit the sales, bring the umbrella. Highs tomorrow will actually occur during the morning with falling temps tomorrow afternoon.

Beautiful, albeit chilly, weather will unfold Saturday and Sunday. Piedmont highs will be 50s with lows at or below freezing. Both days will feature a sunny sky.

Next week...

Another storm system will roll through Tuesday and Wednesday of next week. Look for rain possibilities on both of those days with some colder air to follow by Thursday. That system could involve some mountain snow on the backside as colder air rushes in before the precip ends.

Quiet for travel in our region...

Below is today's edition of the Carolina Weather Video.....



Today is the biggest travel day of the year, and if your travel plans take you anywhere around our immediate region, there will not be any weather problems for you. However, the travel trouble spot today is in the nation's midsection. Rain will occur from the Ozarks into the Ohio Valley. Snow will again fly from the Dakotas into Minnesota and Wisconsin.

For our area, we will see lots of sunshine today with cooler conditions than yesterday...most Piedmont highs will be between 60 and 64 degrees. Speaking of yesterday, a record high of 75 was achieved at the PTI airport.

Our Thanksgiving day is shaping up to be a cloudy, cool, and damp one. Highs will be pretty cool....only low to mid 50s in the Piedmont....and we will have a primarily cloudy sky. Some drizzle is possible at times as well.

Our next front will spread showers in from later Thursday night into Friday, especially Friday morning.

After that front clears, we will have a chilly, sunny forecast for the rest of the weekend. Piedmont highs Saturday and Sunday will be in the 50s with lows in the upper 20s and lower 30s. Highs will be in the 40s this weekend for many mountain spots.

Next week...

Another system will wrap up toward the Great Lakes and bring another cold front our way. Showers, and maybe a storm or two, will roll in Tuesday and Wednesday with a push of chillier air to follow.

The latest model runs have our system at the end of next week well to our north.

Mild with a few showers possible...

Below is today's edition of the Carolina Weather Video....lots of good stuff in there....give it a watch.



Another mild day will unfold around the region today with highs in the lower 70s in many Piedmont spots. A cold front is approaching and will bring the chance of a few showers from this afternoon into this evening. However, rain amounts where the showers do occur will not be terribly impressive.

Tomorrow will be quiet around our region with lots of sun for much of the day and highs in the upper 50s to lower 60s.

Thanksgiving weekend...

Thanksgiving day is looking relatively cool and cloudy with highs in the mid to upper 50s to near 60. Some drizzle is possible, but no real appreciable rain.

Another cold front will slide through Friday and bring some rain, especially through the first half of the day. Then we are looking for full sunshine Saturday and Sunday with chillier temps. Highs should be in the 50s with lows in the upper 20s to lower 30s.

Next week...

It looks like we will have a system move through Tuesday or Wednesday and bring some rain. After that, more chilly air should arrive, and there is the potential for another system around the Dec. 4-6 time frame. The GFS keeps popping a system with the potential for wintry weather with that one....but all I can really say at this point is that yes, there *might* be a system around that time frame......but then again, the northern branch might wind up stronger and crush it. So, nothing too exciting yet. But it is interesting to watch.
