At 8:31 am this morning, we officially made it to the end of summer.
Not very “2020” of Mother Nature, but our temperatures will be below average today!
On the autumnal equinox, there are nearly equal amounts of daylight and darkness. Sunrise in Nashville is at 6:35 am, and sunset is 6:43 pm. The amount of daylight is getting smaller as winter inches closer…
Three of the best words in weather.
A few clouds this morning will give way to a mostly sunny afternoon. High temperatures will reach 75º.
The wind may pick up a bit, but nothing a little kite flying can’t take care of.
A few scattered showers may sneak into Middle Tennessee this afternoon. The HRRR model thinks this is unlikely, though.
Pretty scattered if you ask me… If anything materializes, it will be in the afternoon.
A front that’s currently located over the Tennessee Valley region will move north this afternoon, increasing our rain chances.
See how we are sandwiched between the stationary front (red and blue patterned front) and the warm front (red patterned front)? That means we are in the warm and rainy sector of this frontal system.
There are few things I love more than a cold front on the move. And guess what? It’s happening today!
The cold front that’s stretching across much of the eastern US is expected to approach Nashville around early afternoon, bringing cooler temperatures and lower dew points.
A warm and humid air mass will make it feel like we are stuck in Florida this week. And not the good, “Let’s go to the beach!” kind of Florida.
There’s not a dew point below 70º to be found in the next few days.
Threats Today Include Heavy Rain, Gusty Winds, and Isolated Tornadoes
The remains of Tropical Depression Laura are spinning our way. The storm has finished its trek northward, and today it will set its eyes on Middle Tennessee and Southern Kentucky as it moves east. At daybreak, the storm was at the Arkansas/Tennessee state line.
It was 121° at Death Valley yesterday and 33° in Stanley, Idaho this morning and at 4 PM the NHC issued this Advisory calling for Hurricane Laura to be Louisiana landfalling as a Cat 2 after midnight Wednesday.
Hit-Or-Miss Showers Prevail Today
Low level clouds are lingering this morning. These clouds should dissipate as the sun heats up the surface air.
We are currently sandwiched between two upper level ridges, placing us right below an upper level trough. The trough will create some convection this afternoon and keep a chance for rain showers in the forecast. The HRRR keeps most of our area dry, except for a few pop-ups this evening:
Scattered Afternoon Rain, and OMG It’s Humid Today
An enjoyable morning will set the stage for thunderstorm activity to pick up throughout the day.
The HRRR shows scattered showers mostly missing Williamson/Davidson this afternoon, but I’m not taking the model’s word for it. With the moisture in the air + afternoon heating, I expect more showers to pop up. Some may be in your backyard, some may not.
