Comfortable humidity and temps Monday and Tuesday, let’s goooo.
Humid, summertime airmass arrives Thursday morning and sets up camp. Temps right around and slightly above normal for late June with humidity increasing from Comfortable to Sticky. Humidity will be Uncomfortable Friday through the weekend.
Clouds this morning has knocked the forecasted high down to “only” 94. With the dewpoints in the upper 60’s it’ll still feel closer to 100.
Currently some rain in NW Tennessee and Kentucky. Models don’t think this rain makes it to us and dissipates before arrival.
It’s still hot. Dewpoints in the mid 60’s will make it feel a lot closer to the 100° mark today.
Maybe pop-up showers/lightningstorms, but HRRR (and most) models think this stays to our east, letting us roast.
Correct.
Up to 97° today but dewps in the upper 50’s will make it feel not-so-bad, but still hot. No rain today to put the high temp in jeopardy.
Saturday and Sunday temps will be 96-97 and dewpoints will get buffed into the mid-upper 60’s, so the heat index goes back into the 100-104 range.
(If it is your birthday I got you “at least it’s not eleventy billion degrees today” and this birthday message).
Temps today lower than yesterday’s streak snapping (almost ten years without hitting 100°) and June 22-record-breaking 101°.
BNA last hit 100° July 8, 2012. We might hit 100° this afternoon. For several days forecasters have gone back and forth between 99° and 100° for the high. The latest data supports 99°, but 100° will be in reach. If we make it to 100° we would only tie the June 22 record set in 1988.
HEAT
Summer officially began early this morning.
This streak of near 100° temps will be a dry heat — not Vegas dry, Nashville dry — except for Wednesday when the dewpoint jumps up from the Comfortable to a Bit Sticky into the Uncomfortable area. That’ll send the heat index to 102°. Rest of the week the temp and heat index will be close together.
Heat will build just in time for Official Summer which starts tomorrow.
Models are beginning to agree that we won’t hit 100°, but it’s going to be very close. If we do make it to a hundo it’ll be nice to stop talking about the almost 10 year streak of sub 100° days that started on July 8, 2012.
Yes there are people out there rooting for the temp to reach one hundred degrees. They like extremes. It’s how they’re wired. If are one of them, you are loved. You be you.
Record Heat Incoming?
Dry air started spilling over us this morning.
It’ll get even drier tonight and tomorrow. Red at the end of the below dewpoint GIF is super-dry air: dewpoints in the 20°s!:
A north breeze will blow through the weekend, a gift from the notorious D.A.M.
