Clouds and cold air. Could there be some snow flurries?

Wednesday, December 6, 2017 –

Good evening.  Temperatures were cold again today as we kept cloud cover across the region.  The high for today was recorded at 12:30 AM.

We are going to keep the cold air through the weekend.

Look at this satellite imagery from NOAA.  You can see that the front across the southeast has stalled a bit; therefore, the clouds and moisture ride up the axis of the front from the southeast to the northwest.  Notice also the clouds moving south out of Canada. We will see another surge of cold air on Saturday.

We could see some snow flurries on Friday with a chance of light snow on Saturday.  The best chance for accumulations will be across the higher elevations above 3,500 feet..

The clouds remain in the forecast tonight with a little sun with the clouds on Thursday.

8 PM Tonight – Clouds linger with cold temperatures.

7 AM Thursday – We keep cloudy skies with cold temperatures.

1 PM Thursday – Variable cloudy skies and cold temperatures with highs int he lower 40’s for the Tri-Cities.

5 PM Thursday – We could see some limited sunshine with temperatures in the 30’s just before sunset.

Look for another push of cold air Friday into the weekend.  This is a look at the weekend jet stream pattern.

This pattern in combination with a cold front could bring some light snow to our region on Saturday.

8 PM Thursday – We maintain cloud cover with a slight chance of some mountain snow flurries.

7 AM Friday – A wave of low pressure to our southwest will bring moisture into the area.  We could see some snow flurries with a possibility for snow light snow across the mountains on Friday.

7 PM Friday – Variable cloudy skies are in the forecast with cold air across the area.

1215 PM Saturday – Here comes the next surge of cold air from the north.

8 PM Saturday – Snow showers will be possible with a chance of a light accumulation in the mountains.

8 AM Sunday- Skies will be sunny and high pressure builds into the region.

Here is a look at the projected snowfall for Saturday.  The mountains of east Tennessee and western North Carolina could see a trace to maybe an inch of snow as it appears right now along with the higher elevations along the Kentucky and Virginia border.  It does appear that the best chance of accumulation will be across parts of West Virginia.  Snowshoe could pick up one to three inches of snow.

We stay cold into next week with another chance of snow Tuesday into Wednesday.

Here is a look at the 500 MB charts.  Keep in mind these show what is going on aloft int he atmosphere at about 18,000 feet.

Tuesday – We have another shot of cold air coming down from the north.  The coldest air is in purple.  We will be watching a front across the southeast which will bring us a chance of snow.

Wednesday – The cold air starts moving to the east-northeast.  We will have to watch the low pressure system along the east coast.  Temperatures will be cold enough for snow in the east and the northeast.  Stay tuned.

Have a great night!
