Nashville Severe Weather

A Heat Advisory is issued by NWS-Nashville when they think the heat index (“feels like”) will hit 105°.

• We were under a Heat Advisory for today, but it was just canceled.
• Why? We started “cooler,” there’s cloud cover, and we may get an iso shower or storm this afternoon.
• Max expected heat index today “only” 102°.
• “Only”

What was that about showers or storms today?

• I can’t show you a model that has a storm popping up on us during the day. I’m not expecting rain. It’s possible but yeah, not expecting anything.
• Clouds tossing shade expected to roll in mid-afternoon, right when we’d hit the max feels like temp. Begone 105° heat index potential! Just One Oh Two. Here’s the HRRR model rolling those clouds in:

The Wattery returns next week! Monday especially. read more

No relief this weekend. Heat Advisory today from 11am – 7pm. We’ll probably be reissued one for tomorrow, per NWS Nashville. High temp will get very close to 100°, and the dewpoint close to 70°, giving us a heat index of 105°-109°. No hope for any rain to cool us off. Tomorrow is more of the same story, except maybe some showers around sunset. A/C will be vital. read more

Uncomfortable dewpoints + upper 90°s temps will drive the heat index over 100° starting today, continuing at least through the weekend.

Temps “drop” Monday, but still very humid.

• Temps just into the mid 90°s lol.
• This reason: more clouds due to higher dewpoints should block the sun and interrupt the bake.
• Rain and thunderstorms may develop late Monday afternoon, reducing forecast temps.

Not much happening next several days other than it’s gonna be hot.

Dewpoints in the upper 60°s today through the weekend will be … uncomfortable. Combine that with near 100° temps and we’ll see the Heat Index approach 105°. At 105°+ NWS issues a Heat Advisory. read more

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. read more

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°. read more

Our streak of 28 consecutive days of reaching the 90’s looks to stop at 28. Our high temp looks to only make it to 85° today. It was a good run, some may say a great run. But all good, or bad things must come to an end. 28 days is the 5th longest streak on record. Not as cool of a streak as Cal Ripken Jr.’s or Joey Chestnut. The streak really hasn’t been cool at all, it’s just been hot. read more

Dry air is prohibiting the rain from Kentucky from moving into our area. Would not be surprised if a shower squeaked by, but won’t be anything of major consequence.

Latest HRRR model (below) runs think the rain/storms hold off until after a Nashville SC win. But models aren’t always right. Prepare and plan for the unexpected. read more

Previously mentioned showers coming in from Kentucky look weak. If they do make it here this afternoon, they would just be some very light showers. No need to alter any plans. No severe weather worries with these. HRRR model gives its’ take below. read more

Below I posted the MaybeWrong HRRR model. It thinks light showers descend from KY beginning midnight tonight and hit or miss sprinkle you until around Saturday afternoon. Would not alter plans. Rainfall unevenly spread and very light. No storm concerns. read more
