Saturday’s high humidity (70 at 9:15 PM) is, as I write this, gone. The dewpoint is now 54. So nice, so dry. Thanks, cool front!
That was our cheerful NWS-Nashville, letting us down gently.
Expect a warm/hot, but comfortable, high of 88 on Monday.
A gradual, slow creep, y’all. It won’t be too hot, and the humidity won’t be oppressive. A nice day for the pool tomorrow.
It’s still summer. Do Labor Day right.
Expect high temps in the low-to-mid 90s this week.
Kinda like this:
I’ll let NWS-Nashville break it to you:
... by Thursday afternoon we`ll be looking at the same type sultry conditions we`ve grown so accustomed to over recent months.
Add to that, regarding Thursday:
A return to isolated, pop-up afternoon thunderstorms.We are in nowcast mode @NashSevereWx on Twitter as storms pop up and work their way in from the east.
We will may see a few weak microbursts. Microbursts happen when winds come screaming down from a storm, slam into the ground, then spread out in all directions. Here is an example.
This gif expresses how I feel about the heat:
Here we have the Biebs representing HEAT, sticking out in the crowd, and being obnoxious about it with the gold watch, two gold chains, red hot hat brim, indoor sunglasses, and that unnecessarily cool way he grips the water bottle. I like that he’s hydrating (although, why two tiny sips, Biebs?), but I can’t think that leather (?) garbage-bag-styled shirt is the loose, lightweight clothing that makes more sense during a heat wave. And worst part about it, is the gif never moves on. It’s stuck in an interminable loop.
It showed up today, sweeping away the humid air that’s been hanging around for weeks.
Water vapor imagery shows humid air in white (departing), dry air in black (arriving):
If you pay close attention to the above, you’ll see the humid air sink south of the TN/MS border, then surge back north of it. Although that’s disconcerting, we are confident our drying out trend will continue tonight, tomorrow, and Tuesday.
A humid, but not too unstable, airmass is atop us this afternoon. This means a few isolated rainers have been racing north. This will continue through the afternoon, then start to die down (but not completely killed off) overnight. Any rain we get will be of little consequence.
#1 That “H” in the Atlantic is known as a Bermuda High. High pressure suppresses rain chances.
#2 That “L” is a surface low. It has caused major flooding in Louisiana. It is pulling moisture in from the Gulf and creating a flash flood threat for those to our west and southwest.
