That means ground level ozone concentrations may approach or exceed unhealthy standards. The general public is not likely to be affected. Active children and adults, and people with a respiratory disease such as asthma, should limit prolonged outdoor exertion.
NOTE: Air Quality Alert today.
Hello, humidity! Dew points are going to creep back up into the mid-60s today as high temperatures continue to creep up into the mid-90s.
Later today, a frontal boundary will begin to approach Nashville and middle Tennessee. It may stall out just before it reaches Williamson and Davidson County areas, setting up for a weekend of dodging showers and storms.
Hot, muggy weather is slowly returning.
Even though it’s getting hotter, today should be one final day of comfy humidity. Our high temp will easily move into the low 90°s this afternoon in Williamson and Davidson Co. Dewpoints will remain comfy in the low 60°s, making today to be the last comfortable day for most.
Up goes the mercury in Nashville. Today is going to be the warmest day this week as our warming trend continues. Humidity will be tolerable, some may find it comfortable. We are still in a dry spell, with only an incredibly low chance of an extremely isolated shower and storm somewhere in Williamson and Davidson Counties. (Editor’s Note: It’s not going to rain today).
Just sit back and imagine, rain-free, mid-upper 80º days in June… wait!
No need to imagine, that’s exactly what we are going to have most of this week! Just look at this:
High pressure is centered over central Missouri this morning. It will eventually move into the Tennessee River Valley by tomorrow, maintaining near-normal temperatures with comfortable dew points.
Waking up to a dewpoint of 71° is what you sign up for in Atlanta or B’ham or Florida or Gulfport Mississippi (gooooo mighty Admirals!) but here in Nashville that’s not cool. Upper 60°s dewpoints are fine, that was part of the contract we signed when we moved here, but I draw the line at 70°. I looked outside this morning and sweat formed on half my eyelashes and no one thought that was attractive.
Holy cow! It’s June! Where does the time go?
The overarching system that gave us showers and thunderstorms is on the way out this morning. However, there will be enough temperature recovery with residual small-scale boundaries to produce isolated to scattered thunderstorms. Isolated severe storms cannot be ruled out of the picture; however, the HRRR model doesn’t really think anything of consequence will pop over us today. Below is the NAM3 model:
Showers and storms have already appeared on the radar this morning, but as we are publishing this, the radar is quiet. That won’t last long.
Excessive moisture left behind by Alberto has kept dewpoints in the low 70’s, producing oppressive humidity. As high temps creep towards the 90 degree mark, this is going to be a hot and sweaty day. The moist and unstable airmass will fuel thunderstorm development today.
