Tonight’s second Tornado Watch has been issued.

The first Tornado Watch was issued earlier tonight. It had an expiration of 2 AM.

The tornado threat will extend after 2 AM. So a second Tornado Watch has been issued. This one expires at 5 AM. That does not mean the tornado threat will be over at 5 AM. Do not interpret this as an all clear after 5 AM. It’s possible a third Tornado Watch will be needed. Watches typically only go on for 6 hours. read more

The Storm Prediction Center, in coordination with NWS-Nashville, has issued a Tornado Watch for Davidson and Williamson Counties.

This Watch will continue until 2 AM.

Important! A second Watch (Severe Thunderstorm or Tornado) may be (probably will be) needed after 2 AM. We will not be clear of the straight line wind or tornado danger until probably 9 AM or so. (SPC doesn’t issue 12 hour long Watches for anything; too much can change.). read more

Nice weather tonight, but chilly.

Wind chill from 59° at 5 PM, dropping to 49° by 10 PM.

No rain Monday. Hint of rain possible Tuesday on the Euro model but the system dries as it approaches. Bet on dry. read more

Fog formed on area lakes and rivers overnight. Here’s the sat view of it mixing out.

Today watch for these signs.

A Heat Advisory starts at 11 AM and ends at 7 PM tonight. This means the temp/humidity combo will push the heat index/feels like temp to 105° in shaded areas. Much hotter in direct sunlight. Our local heat index should hit 107° in Nashville and 106° in Franklin. You know what to do. Take breaks, guzzle water, etc. read more

Our smoke is coming from two large wildfires in California. Maybe some Canadian smoke mixed in. Winds aloft have picked it up and blown it a few thousand miles.

It’s making sunrises and sunsets red. Feels equal parts unsettling and fascinating. read more

Low 90s temps in the shade this afternoon and Sunday afternoon.

Low 70s dewpoints this weekend. Heat index up to 99.

Remember, temps and that highly suss number called the heat index (anti heat index rant deleted for brevity) are for in the shade. Official high temps are always taken in the shade. If you’re out in direct sunlight, it’ll be worse, obviously. read more

No hazards ahead. Except for heat.

Rain this morning moved out. We’re good today. And Monday looks quiet.

Looks like next best rain chance is Tuesday. The HRRR (below) has Tuesday morning rain:

The GFS also has not-enough-for-a-rainout rain Tuesday: read more

HRRR model has light rain off and on (mostly off) after midnight into Sunday morning and maybe continuing into early Sunday afternoon. No rainouts, keep your plans.

Earlier model data suggested a thunderstorm is possible north of I-40 late Sunday afternoon. Current data doesn’t. Weekend looks good. read more

Light rain – no lightning or worries – may roll in Saturday night. See HRRR model below.

Sunday morning rain retreats north, like a frightened turtle. Rain may sink south again Sunday afternoon/evening and make it us, but that’s unlikely. read more

Satellite in the sky. We bathe in sun.

I can’t find anything meaningful in the models through the weekend. The Euro tosses a sad, lonely, ineffective shower at us Sunday morning but that looks like nothing. Next week a few systems approach from the west but are battling rain-eroding high pressure as they work east. So while next week looks maybe wet, it’s all too uncertain to comment further. Meh. read more
