Marine Weather and Tide Forecast for McMinnville, TN

SHORT TERM
(Rest of today through Tuesday)
Issued at 1041 AM CDT Mon Aug 3 2026

Patches of light rain and drizzle are showing up along and near the Cumberland Plateau this morning as an upper low circulates over the Appalachians. The 12Z sounding from OHX shows a stable air mass in place, for once, and largely dry above ~775 mb. So we're certainly expecting no hazardous weather today, or any time in the foreseeable future for that matter. Temperatures will gradually warm back up after today, and we're keeping low to medium PoPs in for mainly the Cumberland Plateau and adjacent areas tomorrow as the pesky upper low refuses to budge.

LONG TERM
(Tuesday Night through next Monday)
Issued at 1041 AM CDT Mon Aug 3 2026

There are better rain chances on Wednesday as the aforementioned upper low retrogrades and pulls additional moistures into Middle Tennessee, but QPF values are quite modest and we don't anticipate anything impactful. By Thursday, temperatures will be at or slightly above seasonal norms, and we may see heat indices reach the low 100s in some of the hotter locales. This will remain the case through the weekend, although it appears that we'll stay just below Heat Advisory criteria each day. Better rain and storm chances will spread across all of Middle Tennessee from Friday through the weekend as the next surface boundary and upper trough approach Middle Tennessee from the west, although there's nothing yet to hint at much of a severe weather risk. Total QPF from today through Sunday night continues to represent quite the gradient, with values ranging from less than 0.1" near the Tennessee River to 1"+ across portions of the Cumberland Plateau.
Despite the return of seasonal heat and humidity and persistent rain chances, the risk of severe storms, flooding and heat-related hazards are all very low throughout the 7-day forecast.
