Warm air blows in ahead of rain and possible storms on Sunday
Finally...warmer air is starting to move into our area! A gusty wind (at times) out of the south will help temperatures rise to near 80 on Friday and Saturday.
In the days leading up to the Food City 500, the most important thing may be the sunscreen. With temps topping out near 80, we wear less clothing. However this time of year, the sun's peak angle is just as high as it is in late August. Make sure to keep applying sunscreen, if you're going to be out and about for long periods of time.
As a cold front gets closer to the region on Sunday, the rain chances start to increase. Currently, we see the best chance of rain spreading from west to east from 12 p.m. onward. These rounds of rain may contributed to an isolated flood threat on Sunday, with a slightly better chance of that occurring on the TN-NC line.
The best chance of flooding will be near creeks and streams and/or in low-lying areas. Rivers currently are not forecast to reach flood level on Sunday.
We don't think we'll see the nightmare situation that unfolded in 2017. In that instance, a steady soaking rain lasted for more than 48 hours and dropped more than three inches of rain. In this case, we see a few periods of rain on Sunday dropping less than that. Beaver Creek may still rise to/above its banks, but not to the extent that it did just last spring.
Rain and perhaps a few storms on Sunday would likely fall below severe weather criteria (60 mph winds or more, 1" hail or greater, and /or tornadoes). The main impact on Sunday will likely be race delays, if not postponement.
What is the one thing that could actually make things drier? Well...if storms really fire up along the Gulf Coast, this could rob us of the potential for a widespread soaking rain of 1-1.5". I doubt that we'd be completely dry, but that may actually alleviate some things and allow us to get some racing in on Sunday.
Behind this storm system, watch out! Temperatures drop into the 40s for daytime highs on Monday. In the event that the Food City 500 gets postponed, you'll want to adjust the wardrobe to something that will keep you warm on Monday.
