Friday, December 1, 2017 –
Good Evening. Temperatures were pleasant again this afternoon.
It looks like we keep the mild air through Tuesday of next week.
We have rain in the forecast on Tuesday. That is the beginning of this weather pattern change coming our way.
Let’s talk about the current weather. Here is a look at the latest satellite imagery from NOAA. We continue with more of a zonal flow – meaning weather is moving from the west to the east.
That satellite image correlates to the current jet stream weather pattern.
We will keep variable cloudy skies in the forecast overnight into Saturday.
8 PM Tonight – We will see some clouds on the horizon with chilly temperatures.
8 AM Saturday – variable cloudy skies are forecast for the region.
1 PM Saturday – We keep variable cloudy skies with mild temperatures.
5 PM Saturday – Variable cloudy skies will prevail with temperatures in the middle and upper 50’s.
Now lets take a look at next week.
8 PM Saturday – We still have some clouds on the horizon, but skies will clear overnight.
8 AM Sunday – We start the day chilly with just a few clouds around.
Noon Sunday – Partly cloudy skies are forecast for the area with temperatures by noon in the 50’s.
7 PM Sunday – We keep fair skies with mild temperatures.
9 AM Monday – We start the work week with sunny skies and mild temperatures.
5 PM Monday – Partly cloudy skies are forecast for the area with temperatures in the 60’s.
6 AM Tuesday – We will be mild Tuesday thanks to a strong south, southwest wind ahead of a strong cold front. We will see showers move into the region by the afternoon and evening. I would not be surprised to see our high hit 66 early in the day.
Here is a look at the jet stream pattern for the middle and end of next week. That cold air will plunge south and southeast.
So here the a look at the progression of the cold air next week. We could see rain and snow showers late Wednesday into early Thursday. There will also be a chance of some light snow on Friday.
I want to point out that the following maps are 500 MB charts – These are forecast maps for about 18,000 in the atmosphere. The red lines are what we call trofs. You can see the high and low pressure areas. Notice the big dip in the jet stream in the east while the ridge of high pressure builds in the west. This ridge is what will displace the cold air and send it south next week.
This is the forecast map for Monday- We are still in the mild air.
Tuesday – You can see the storm system moving into the Great Lakes. This will start the weather pattern change for the east.
Wednesday – Low pressure will continue to strengthen over the Great Lakes which will push the cold air south and east.
Thursday – The cold air moves into the Tennessee Valley.
Friday- Very cold air remains in the east. We could see some scattered flurries.
Saturday – The cold air holds in the east while the mild air covers the west.
With the cold air heading south, we will are in store for the coldest air of the season so far.
Have a great weekend!
