A heat advisory is in effect again today as the combination of low 90s and high humidity will lead to feel like temperatures in the lower 100s. Be grateful, as West TN and KY have peaked out as high as 115-120 in recent days. Thankfully, a cold front will work through tonight and Saturday, bringing mid to upper 80s across the area.
As far as rainfall, isolated showers/storms are possible today, but chances increase tonight and into Saturday with the approaching frontal boundary. In terms of severe potential, timing is on our side. The overnight timing will aid in lessoning the amount of energy storms can use. With that said, still can't rule out strong wind gusts as the line works through. Heavy downpours will also be a concern. Given the heavy rainfall at times this week, some locations will be more prone to flash flooding through tonight and into Saturday. By Sunday, any lingering showers/storms will slowly work out, leaving dry conditions Sunday night and into the new work week.
As an average, rainfall amounts today through Sunday morning will be in the 1 to 1.5" range. This is good news for some, as many in Middle and West Tennessee are dealing with drought. Even so, the better potential is from roughly Nashville and east. This should really help a large portion of the state recover a bit.
Severe potential is low but not ruled out tonight. Strong to damaging wind gusts will still be possible as well as flooding/flash flooding. Drier and cooler conditions will arrive briefly Sunday, before warming conditions return early next week.
