Nashville Severe Weather

Brushfires could spread.

• Low relative humidity and winds 10 to 15 MPH expected today and tomorrow.
• These conditions can spread fires, especially where little rain has fallen lately.
• But the concern is low.
• NWS-Nashville is monitoring. They have not issued any warnings (called Red Flag Warnings). Winds aren’t quite strong enough to raise serious concerns. And it may not be dry enough.
• We will update you on Twitter if this changes.

Locate your morning jacket, fam.

Ian’s after-landfall, inland path is unknown. One set of models brings its remnants into Middle Tennessee this weekend. Rain the only impact. read more

Rain today should miss us.

South and east of us according to the HRRR model 👇🏽.

No promises but activities today look good.

Maybe don’t burn things tomorrow.

Where the ground is dry, when relative humidity drops, and where wind is picking up, you should not burn things. Fire loves dry ground, winds, and low relative humidity. This will be Monday, which “could bring some marginal fire danger.” read more

Rain is on the Saturday morning radar. This 👇🏽 is from 7:30 AM. See this for an updated image.

Some of this rain is not reaching the ground. Most of it is.

The rain is light. I’m bringing a rain jacket to rollyball fields this morning. read more

When you run a poll the day after it was 100°:

I’m going to rerun this thing in late winter after a cold snap to see what happens.

FWIW (nothing) I’m team summer, my feet never get warm in the winter. read more

High today only 81°.

It’s still a bit humid right now. This afternoon, a cold front will sweep away yesterday’s humidity 👇🏽

A few light showers may get caught up in the airmass change today, but they’ll be of little/no consequence. HRRR model 👇🏽. read more

97° is the record high September 21 temp. We should break this record. The official forecast high is 99°.

(Some were asking if we would hit 100° but models aren’t so sure we’ll get that far over 97°. Clouds may slide over the official observation sight. The heat making ridge may be weakening just a bit). read more

The record high for today /checks calendar/ September 20 is 97° (2018). 96° is forecast.

Tomorrow the record is 97° set in 1955. We are forecast to break that record (98°).

Humidity should be higher than previous forecasts. Mid/Upper 60°s dewpoints will drive the heat index to 100° today and 99° tomorrow. read more

Moving this morning in our general direction are storms that last night caused Severe Thunderstorm and Tornado Warnings in the midwest. This storm complex is now much weaker and crossing the Ohio River, moving south through Kentucky. Most models think these storms will further decay and then completely fall apart before the Tennessee state line. (A few models predict the system – while weaker – will at least hold its precip and cross into Tennessee along and east of I-65). read more

Hot, but not as humid as the other heatwaves this summer. Dewpoints upper 50°s (Comfortable) / lower 60°s (Sticky) during this End of Summer Heatwave.

There’s little to no hope of rain in the next 7+ days. read more

Today will be the same as yesterday and the day before. Then things get…worse.

• The dewpoint will rise a from Comfortable to Sticky starting Sunday, continuing through Wednesday.

• Temps go Full Summer through the end of Summer. Fall begins Thursday at 8:03 PM.

This is hot but it’s not even close to the worst heat we’ve seen this summer because dewpoints — although Not Great, Bob — won’t be that bad. read more
