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:
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.
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.
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.”
A Hot, Potentially Stormy Start to the Week
You know the drill by now: hot and humid today, with a chance for scattered showers this afternoon.
The dewpoint will hover around 71º. As of 11am, the heat index at BNA was already 100º, so I wouldn’t be surprised if we approached a heat index near 105º by this afternoon. If the temp soars, the humidity will come down a bit. But if not, the humidity will stick around. Either way:
