Rain for Wednesday with cold air returning just in time for Christmas!

Tuesday, December 19, 2017 –

Good Afternoon.

It certainly has been a beautiful afternoon.  Temperatures managed to climb to the lower 60’s in the Tri-Cities.  Clouds and rain are back in the forecast for tonight and Wednesday.  Take a look at the current satellite imagery from NOAA.  You can see the moisture coming into the area from the southwest.

Temperatures will stay mild through Saturday.

Rain chances increase overnight into Wednesday with more rain on tap for Friday afternoon into Saturday.

The Storm Team 11 forecast calls for an increase in clouds and rain tonight into Wednesday.

8 PM Tonight – Clouds are here with scattered showers.

5 AM Wednesday – Keep the umbrella out when going to work.  Clouds and showers and likely.

8 AM Wednesday – Cloudy skies and rain are in the forecast for much of the area.  Locally heavy rainfall will be possible from Tennessee south.

1 PM Wednesday – We keep the cloud cover with scattered showers.

5 PM Wednesday – There could be some sunshine across the northern counties; otherwise clouds and scattered showers will be possible.

We will see a bit of a break on Thursday with variable cloudy skies and mild temperatures.  Rain is back in the forecast for Friday and Saturday.  We could find some locally heavy rain coming our way on Saturday.

Rainfall potential through early Thursday.  Once again, the heavier rains will be from Tennessee south.

8 AM Thursday – Low pressure will move east taking the rain with it, but we will be left with clouds.

1 PM Thursday – Variable cloudy skies are forecast for the region with temperatures in the 40’s.

9 PM Thursday- The clouds linger, but we could see a few breaks in the clouds overnight.

1 PM Friday – Here comes the next weather maker.  Clouds and scattered showers are back in the forecast.

5 PM Friday- Rain chances are going up as a cold front pushed into the Tennessee Valley.

7 AM Saturday – The cold front will bring some locally rainfall to parts of the Tennessee Valley Saturday.

How about the Christmas holiday?  Models are trending colder Sunday into Christmas.  Right now it looks like we will have a chance of rain on Sunday with rain changing to snow late Sunday into early Monday.  At this time, it does appear that snowfall totals would be light.  The forecast for Monday is still subject to change; however,  it does appear that the cold air will make a comeback late in the weekend into early next week.  Stay tuned.

This is a look at the upper air chart – 500 MB -18,000 ft high for Monday morning.  There are signs that the cold air will push south behind the cold front.  The amount of moisture behind the front is still not certain.  Right now, it does look like we could see some light snow or flurries Christmas morning.

Here is a look at the surface map for Christmas Day from NOAA.  Most of the moisture will be to our east.

Enjoy the warmth through Saturday and keep your umbrella close by.

Have a great night!
