A Welcomed Pattern Change On The Horizon

8/8/2022

Good morning! Our continuous rounds of showers and storms find us once again today. The good news is
activity is be fairly sparse, with only isolated chances (20-30%) this afternoon to early evening. The heavy
hitters will arrive tomorrow and especially Wednesday. A slow moving cold front will crawl into the area,
bringing between 1 and 3 inches (and locally more) the next few days. Looking at the Day 2 (Tuesday) flash
flood potential, a Marginal to Slight risk is in place. A Slight risk entirely encompasses the area Wednesday, with isolated to scattered instances of flooding/flash flooding.

Breaking things down a little deeper, the approaching front will generate the development of storms tomorrow afternoon. These will continue, though fade is spread, overnight Tuesday. Activity will revamp Wednesday, bringing heavy rainfall rates and a few strong thunderstorms. As the boundary drifts south, lingering showers will be possible into Thursday, before much needed drier conditions prevail. We also find ourselves in a cool period, with highs Friday through the weekend BELOW average! Dew points will also be much lower, making things feel late Summer-ish.

Looking at the expected rainfall amounts on Wednesday, East Tennessee could see between 1 and 1.5". This is an average, with some locations likely topping 2" within stronger and persistent storms. Keep your safety in mind if in flood prone or low lying locations. Chances are a few of these locations will see higher running water tomorrow and Wednesday.

That will do it for today, our last wave of heavy rainfall and warm/muggy temps, before a welcomed pattern change late week. Highs Friday and the weekend will top out in the upper 70s to low 80s!
