Rain and Wind for Saturday afternoon and night – Some could see a little light snow

 

Friday, November 17, 2017 –

Good Evening.  We certainly had a beautiful afternoon.  Check out out the climate data for today at the Tri-Cities Airport.

Our next weather maker will bring clouds to the area after midnight.  You can see that system from the Ohio Valley southwest to Oklahoma on this satellite imagery from NOAA.

This evening will give way to fair skies, but the clouds will move into the area after midnight.

8 PM – Clear and cool conditions will prevail.

Midnight tonight – High clouds will start to increase across the area.

7 AM Saturday – Clouds increase and so do the winds.

A Wind Advisory is in effect for Saturday.  Winds will be sustained at 15 to 25 with gusts to as high as 40 mph.

Noon Saturday – Mostly cloudy, windy and mild weather is forecast for the region.  Notice the showers off to our west.

5 PM Saturday – The strong cold front will move towards the region.  This will increase the chance of showers and a possible thunderstorm.

The main threat for a  few strong to severe thunderstorms will stay just to our west.  We can’t rule out a few thunderstorms in our area during the evening as the front moves through.

8 PM Saturday – Here comes the front!  Showers and a few thunderstorms will be possible.  Heavy rains and gusty winds will also be possible.

Rainfall potential through 2 AM Sunday.

The front will move through the area between 8 and 9 PM.

Take a look at the Jet Stream right over us late tomorrow night tomorrow night.  Winds at 30,000 feet will be near to 100 mph.  Image UCAR

As the front moves through, watch for the rain to change to some light snow across the higher elevations Saturday night into Sunday morning.

5:45 AM Sunday – The cold air moves into the region with lingering snow showers across the mountains.

11 AM Sunday – Sunshine returns with cold temperatures.

The higher elevations above 4,000 feet could see a light dusting to up to an inch of snow.  The Smokey Mountains could see a trace to as much as two inches of snow through Sunday morning.

We will be sunny and cool on Monday.

The cool temperatures will stay with us much of next week.  A look ahead to Thanksgiving Day – Partly cloudy and cool with a high in the upper 40’s.

Have a great weekend!
