At 10 AM a heavy rainstorm was moving across Nashville south of I-40 and all of Will Co. This morning’s weather balloon showed over 2″ of precipitable water content, setting us up for Day 1 of what should be a soggy trio of days ahead. read more

Showers and storms will start to dot the radar this afternoon.

HRRR Model fires up storms just after noon and keeps them around a few hours after sunset.

Temperatures will still be in the low 90s but where showers do form, expect a brief cool off. read more

Scattered showers and thunderstorms expected to make an appearance this afternoon.

HRRR model below is not showing great chances for Nashville this afternoon, but make no mistake. We’re all fair game for typical pop-up storms today. Storm organization will increase later in the week. read more

Monday

We’re still following that typical summertime pattern: hot and humid with some afternoon storms.

Same forecast as the past several days: hot, humid, chance for mainly afternoon/evening thunderstorms.

Will it rain at your bbq at 5PM? We simply don’t know. Someone’s bbq will probably get rained out at 5PM, but we can’t pinpoint exactly who will get it and when it will happen. Not in the summer. read more

Saturday: Be Aware of Heat Index and Scattered Thunderstorms

Same forecast. Again.

The dewpoint will hover around 72º all day, making for a heat index just under 100º.

Watch for scattered thunderstorms starting late morning and extending to sunset this evening. Predicting storm locations in the summer is near impossible, especially this far ahead of time. Here is the HRRR’s best estimate of where and when storms will arrive: read more

Friday

At 10 am, the heat index has already been recorded at 90° and the dew point at 72°.

Rain streaked by this morning north of I-40, with a few downpours south of I-40. Clouds were dragged along with it. This may wreck our rain/storm chances this afternoon.

Maybe.

Why?

Most summertime afternoon storms occur because of the heat-of-the-day. Cloud cover has kept the highs down, interrupting/delaying this storm-making process. read more

Couple degrees cooler this afternoon because of more cloud cover. Highs only around 93…

But it’s still oppressively humid.

Already East Nashville, Fontanel, Riverwalk are in-line for storms. Will it storm in your backyard? Maybe or maybe not. HRRR Model thinks someone will get the water balloon during the afternoon/evening hours. read more

Another typical summertime forecast. It’s miserably hot and humid with high temps today in the mid 90s.

Afternoon storms are bit more likely today. Showers/storms will break out across the region around 1 PM and will come and go. Some storms could contain strong winds and heavy downpours. Will you get one? Who knows, models do not do well predicting the “where,” although they do OK with the “when.” read more
