The Heat Is Back Along With The Wattery

July was kind enough to give us one day below 90°. It looks like there is a good possibility we finish July with all but one day (yesterday) 90°+.

Today will be the “coolest” day of the foreseeable future. High should reach 90°, paired with dewpoints in the low 70’s will give us a heat index that approaches 100°.

HRRR model (above) thinks the Wattery starts sometime this afternoon. There’s never a good ETA with the Wattery. Some of these could be capable of some lightning, but not worried about any severe weather today. HRRR also thinks there is a break in the rain around dinner, and then wants to throw us some no-consequence showers overnight. Those should end before your morning commute.

Overnight, NWS Nashville issued a Heat Advisory for us from 11am – 7pm on Wednesday. High temp of 97° paired with dewpoints in the low-mid 70’s will let us roast with a heat index from 105° – 109°. Those values are measured in the shade, so in the sun will feel worse.

HRRR model thinks the Wattery takes a break tomorrow. I’m not too convinced on that considering our atmosphere will have plenty of moisture and CAPE. H-triple-R model (below) does think a cluster of storms could visit us overnight. It keeps most of the activity to the north and east. Regardless, not worried about any severe weather. But could get noisy enough to wake up pets and/or youngins’.

Thursday dewpoints drop to the mid/upper 60’s for the rest of the week. Which I’m sure would feel great if the high temps weren’t flirting with the 100° mark everyday. Wattery chances most days to try to help extinguish the heat, but relatively low chances. Looks like another long 90°+ streak may get going…
