Good evening Tennessee Valley and a very Happy Friday! Temperatures fell short of the forecast high with the official high at HSV coming in at just 56 degrees. Now that’s not awful given that it is still a few degrees above average. In the rain department locally some have seen close to 1.5 inches.
As an area of low pressure continues to push east this evening and will eventually push more NE as we head into the day Saturday. As the low pushes east and northeast the rain chances will drop for the first half of the weekend. While showers remain in the forecast for Saturday, I expect it’ll be lighter and a bit more on the scattered end. We should not see the downpours tomorrow we saw early this morning.
The aforementioned low will continue NE on Sunday and we should then dry out and we’ll see a few glimpses of the sun as well. By Sunday a large upper level ridge will begin to develop off to our west and push its way into the Tennessee Valley for the start of the new workweek. Monday and Tuesday will be quiet with plenty of sunshine and average temperatures for mid-December.
Now come Wednesday of next week things begin to get a little more interesting. I noticed a developing trough that will kill any ridging pattern we will have previously been sitting under. This trough will once again be sitting over Texas, but models kind-of have it falling apart. It’s not so much that it’ll fall apart, actually it’ll get overtaken by a bigger trough system sitting to the north of Minnesota by the end of the day Wednesday.
That system will dive south on Thursday, but the parent low should stay just to the north. Still looking at the models it does look like the base of that trough will push through Southern Tennessee and Northern Alabama. The EURO is trying to suggest some rain will be the result of this, but the GFS keeps us completely dry all next week. For the time being, I’ll put in a small chance of rain especially since next weekend will be the last travel and shopping weekend before Christmas.
