Some morning showers moved through this morning and left as quick as they came.
HRRR model keeps us quiet through the evening, but cannot totally rule out a few Wattery winners this afternoon. Upper 90’s + dewpoints in the low 70’s will give us a heat index in the 105°-109° range, reason for the Heat Advisory. Counties just to our west are under an Excessive Heat Warning. We’ll pass. If you have to be outside today, give your body some breaks. Heat exhaustion/stroke is no joke and it will creep up on you.
Activity picks up tonight when a weak “cold” front comes in from the NW.
This particular run of the HRRR model thinks a majority of the action misses us to the north, with only some showers/storms coming in the wee-hours of Thursday. This model may be wrong and the majority of the action may hit us, or we could get nothing at all. We’ll know a lot more when the storms show up on radar this evening. Regardless, we are looking at a low-end threat of damaging winds. We are not outlooked for hail or tornadoes. Rain should be gone for the Thursday AM commute.
The bad news is the “cold” front will not make it any cooler. However, it will knock the dewpoints down into the mid/upper 60’s for the rest of the week. Which is kinda good but the drier air also allows for the temperatures to climb higher, so we may see some triple-digit temperatures this weekend.
Wattery winners will be very few and far between from Thursday through the rest of the week. Not good news for anyone looking for heat relief. I suppose good news for people with outdoor plans, but NWS Nashville thinks they may issue more Heat Advisories for the weekend.
“Where is any relief?” you might ask. Truth is, not totally sure. The Euro thinks we get below 90° not this weekend but the next. The GFS thinks we bake well into August.
