A beautiful start from the TDOT SmartWay cam along I-40 this morning. Temperatures for many sit in the mild mid 50s with highs to warm near the 70 mark this afternoon. That said, cooler temperatures are coming, so break out that cooler gear.
We will stay dry today and tomorrow as a cold Canadian high sits in control well to our north. During this time, a low pressure system will develop across the west, shifting east and arriving to the Ohio Valley by late Thursday. This will lead to isolated showers Thursday, with the bulk of activity overnight and into Friday. Similarly, a passing cold front will lead to much cooler air for the weekend, where another system could bring precipitation chances Sunday and into early next week. There remains quite a bit of uncertainty with this later system, so will keep a close eye on how things evolve moving forward.
In terms of temperatures, cooler air is coming. In fact, highs tomorrow (Wednesday) are expected to top out in the mid and upper 50s. That will be a 10 to 15 degree swing from what we see today. Additionally, a cold front Friday will lead to chilly weekend temperatures. Looking below, Sunday highs could be as cold as the mid and upper 40s. We will wait and see how strong the cold air advection regime ends up being, but this is all to say below average is anticipated Sunday and into early next week.
Enjoy our last bit of sunshine and warmth today, as cloud cover and cooler temperatures return Wednesday. Fortunately, we will hold off from seeing showers until later in the day Thursday and through Friday. Have a good one and don't forget to check out our video forecast below.
