Grab an Umbrella!

No lack of cloud cover as we kick start the work week!


Plenty of rain to go along with the clouds (7:42 am as I write here). Mainly impacting areas west of I-65 and mainly in the form of plain ol’ light rain…nothing severe.VIDEO RADAR

All of this moisture is ahead of a frontal boundary, currently positioned just south of our state, continuing to lift on a northerly path.DD SATRAD3D Zooms

This brings our greatest shower and storm chances during the morning into the early afternoon, fizzling out by the later evening.WSMV RainChanceGRAPH

So where does this put us in terms of rainfall totals you may be wondering. We’re actually at a surplus! 3.01″ for the month of August, 31.53″  since the first of the year, bringing us to a whooping 1.07″ surplus for the year. With additional rain expect this week, this will only add on!


Clouds and rain serve as a blanket for an unseasonably cool day ahead. Average is 89 and I expect most of the Mid State to hang strong to the lower 80s. Not long, though! Back to normal upper 80s to lower 90s as soon as tomorrow.WSMV_TEMP CYLINDERS TN

If you’re looking for something fun to do tonight, The Sounds game will be an excellent choice! Most of the rain will be out of our hair (besides that 20% isolated chance), expect clouds and muggy conditions with a first pitch temperature of 79 degrees. WSMV FIRST PITCH

It’s still a week out but not too early for a general forecast of the anticipated Total Solar Eclipse! Out of a 1 to 10 scale, Nashville gets a 7 for a decent forecast! We’ll see a few clouds but it’s not looking overcast by any means. I do expect the clouds to be slow moving which is not good news if you do get a cloud overhead. Of course, it’s still early but all hands are on deck and we’ll keep you posted with the most up=to=date changes.


Meteorologist Dan Thomas will be tracking the rain coming up on News 4 at noon today!

August 13: An Unsettled Week Ahead

Some showers are trying to make their way in from the southwest this evening — I don’t think it will wash out your evening plans, but some passing showers could wet things down a bit.  We’ll see increasing rain chances tonight, especially after midnight, and the rain will likely be a factor for the Monday morning commute.  The HRRR model’s radar simulation shows the showers spreading in, with the heaviest rain around sunrise Monday:

I can’t completely rule out a couple of strong wind gusts, but overall our severe weather potential is low.  The storms could produce some heavy rainfall though, especially south of I-40…be watchful for standing water on the roads as you’re heading out tomorrow:

Temperatures tonight will drop to the low 70s, then we’ll only warm up to the low 80s by Monday afternoon:

Lingering showers and a few storms will still be possible Monday afternoon, but they won’t be as widespread as what we’ll see in the morning.

An unsettled weather pattern will prevail through the rest of the week, with high temperatures in the upper 80s and low 90s, and a 30%-40% chance of mostly afternoon storms every day:

Looking farther ahead, Eclipse Day is looking a little better — still a chance of spotty storms, but that’s always a threat this time of year, especially so far in advance.  The European forecast model (the most-reliable long-range model) shows just a slight storm chance…and of course, plenty of warmth and humidity.  It’s still a very preliminary forecast, and of course we’ll keep you updated over the next eight days:

Pleasant Day….Then Rain Returns

Today will be a very pleasant August day, with moderate temperatures and humidity for the this time of year.

As of 7:30am, clouds are beginning to stream in from the west.


It’s still bright though in many communities.


The Cumberland Plateau and nearby towns are dealing with some patchy dense fog.  Give it until 8:30am.  Then, we should be in good shape in that regard.  The areas in yellow indicate visibility around 1 mile.  In the orange, it’s 1/2 mile.  In the red, visibility is around 1/4 mile.


The Mid State is dry, but there IS some rain over Arkansas.


Clouds will win out over sunshine at times this afternoon.  The sunniest part of the area will be southern Kentucky.

As for any rain chance…notice that the only shower chance today will be at the lower corners, late this afternoon.


As I alluded to above, high temperatures this afternoon will be a little below average.

DT 4 RPM 12KM Temperature2

FUTURECAST shows some of the rain back in Arkansas moving in late tonight and tomorrow.  It’s not going to be a washout of a Monday, but there will be some spotty showers and thunderstorms, so be sure to keep your umbrella nearby.

More spotty storms are in your forecast this week.  We’ll talk more about that and have an update on the forecast for the Total Solar Eclipse, which is just over a week away, on News 4 at 8am.  We’d love to you have you join us!

Mini Break from the Rain

Not a bad start to our Saturday evening! Clouds blanket the sky for many but there’s not a whole lot of rain ringing out of them!


Just a few light spotty showers across southeastern Middle Tennessee, in the midst of pushing southeast, out of our hair!VIDEO RADAR

Temperatures are nice and comfortable, in the upper 70 to middle 80-degree range.WSMV DMA TEMPS ZOOM1_EffectSquiggle Autoplot

If you’re hoping to a get a round of golf in, Sunday will be your morning. Variably cloudy skies, rain-free and lower humidity is what you can expect. The earlier, the more comfortable temperature-wise.


After you score a round of golf, how about a dip 8in the pool? Sounds good to me! Daytime highs will run about five degrees cooler than average, in the middle 80s and humidity will be slightly lower.DD_Pool_WeekendOutlook

Mugginess soon returns by early next week, lasting through our entire 7-Day! We’ll also have rain chances each and every day. Check it out…7 Day PM

I’ll have the full breakdown on your 7-Day coming up on News 4 at 6 and 10 tonight. Hope you join me!

Showers Today, Gone Tomorrow

Today will be a little unsettled.  We’ll have spotty showers popping up here and there.  Then tomorrow, the rain will be gone and humidity will decrease some too.

Outdoors as of 8am it’s mostly cloudy.  There are a few sunny breaks, but most of us are dealing with clouds.


Temperatures are in the 70s.  It’s very humid, as well.


4WARN Live Doppler Radar, Middle Tennessee’s only live radar, shows some rain over our northeastern counties, gradually moving toward the Cumberland Plateau.


As the day progresses and the air warms, scattered showers and a few thunderstorms will develop, partially in response to a weak cold front moving through.  Notice how late morning through the afternoon looks to produce our best chance for rain.

DT DAYPART RainChances

With all the clouds and the expected areas of rain, temperatures should remain below 90 again!

DT CITYCAST 3D1_EffectRandomDots_16x9

The East Nashville Tomato Art Fest will be a fun one to take in today.  Again, while there could be a few showers, for the most part the weather will cooperate.


The Decatur, Macon, Williamson, and Putnam County fairs all continue today too.  Here’s Williamson’s forecast:


In Putnam County, showers will be winding down tonight making for a fun evening on the midway!


FUTURECAST shows how rain showers will be most prevalent around the middle-latter part of today…

Behind the cold front, clouds will break some overnight.  If you like, go outdoors and see if they part enough in your area to let you witness the peak of the Perseid Meteor Shower.  Meteors will be traveling in all directions across the sky.  However, they’ll all emanate from constellation, Perseus, the radiant point of which will be rising out of the northeastern sky.  Try to avoid any lights nearby while viewing.  The moon won’t help, but it’ll take several hours for it to rise, which of course will work in our favor.


Tomorrow, we’ll have a mix of clouds and sunshine with the accent on clouds at times as a weak weather system now over the Plains states moves into our area.


Join Alan Frio and me on News 4 at 8:30am.  I’ll talk about what’s in store for this coming week…plus have an update on the forecast for the upcoming Total Solar Eclipse!

Better Weekend Forecast…10 ’til Eclipse


Rain and thunderstorms are dotted across the Middle Tennessee as the weekend begins.  The rain has really been coming down heavily south of I-40. There has been flooding in Marshall County tonight.  As of this writing, a Flood Warning remains in effect for Giles County until 9pm.

LS PICTURE vertical 1.png

Computer models have not handled this system very well, they have been flip flopping day by day on the chances of rain for the weekend and beyond. Here’s the latest depiction for tonight and tomorrow.

So basically don’t be surprised if we have a few more showers and maybe even a thunderstorm or two pop up tonight.  We are not looking at anything severe. Tomorrow I think we will have a few areas of rain early then it will push to the south.  Some clearing should take place later in the day.  Temperatures will reach the upper 80s. Sunday looks dry for the most part. And after much consideration and review of the latest model runs, I have decided to lower Monday and Tuesday’s chance of rain to 20%.

This will make for a much better forecast for outdoor fun this weekend from the Tomato Arts Fest to county fairs to Shakespeare in the Park. Enjoy! Of course it will still be warm.


Now let’s turn our sights to the Great American Eclipse.  We are 10 days away…so it’s time for a preliminary forecast. It’s not looking good.  The pattern looks unsettled.  What we call a “northwest flow” will set up, this tends to bring us more cloud cover and right now it looks like some scattered showers and thunderstorms.


But let’s not worry yet, we are still over a week away and weather systems can speed up, slow down and change all together.  We’ll keep updating you as we get closer to time.

Weekend Looking Better than Before

We all know the weather forecast changes from time to time.  It has to.  The atmosphere is far too vast and complex, even in this day and age, for meteorologists to sing the same song perfectly consistently about weather for an upcoming day or event.  This weekend is one of those times.

Earlier in the week, it looked like scattered showers and thunderstorms would be a BIG part of our weekend outlook.  Now…not so much.

This morning (as of 9am), it’s variably cloudy, warm, and muggy.  Temperatures are running in the 70s and lowermost 80s.


A few showers have formed on and near the Cumberland Plateau, as shown on 4WARN Live Doppler Radar.


Later today, showers and thunderstorms will become more widespread in coverage, as a cold front now over the Plains states closer to Middle Tennessee.


Here’s your rain chance today…

DT DAYPART RainChances

FUTURECAST shows the increase in rain coverage as we get into the afternoon.  Widely scattered rain and storms will linger into tonight, although over time, they’ll gradually diminish.

Tomorrow, the best rain chance will be along and south of Interstate 40.  During the afternoon, as slightly drier air funnels in, some folks especially over southern Kentucky will notice the humidity coming down slightly, in the wake of a weak cold front.

WSMV Weekend EMOJI Forecast

Much of Sunday looks excellent!  Then, late Sunday afternoon or Sunday night, another weather system will begin to move into Middle Tennessee from the west.  That’ll bring another round of rain and thunderstorms, many of which will linger into Monday morning, for the commute.

WSMV Weekend EMOJI Forecast2

Coming up on News 4 at Noon today….we’ll talk more about this weekend.  PLUS, I’ll share a bunch of fun things to do outdoors this weekend, so you can take advantage of the relatively nice weather we expect.

Hope you join us then!
