“Cooler” Temps in Exchange for Some Rain + Storms

By on

Fog this morning mixed out fairly quick. Here comes another day of hit or miss showers/storms and a little less heat than the past few days.

Similar to yesterday, storms should start popping up sometime in afternoon, then slowly start to dissipate by sunset. It is entirely possible you don’t get any rain today, but if you do, a storm could contain some heavy rain, gusty winds, and lightning. A storm or two could contain microburst winds, similar to what parts of Nolensville saw yesterday. Microburst winds cause damage to low-end tornadoes. They are can be difficult to warn on because they occur between radar scans. No organized severe weather or tornadoes are expected today, or the next few days. read more

Heat Advisory Continues Today; “Cooler” Temps Ahead

By on

A heat advisory is still in effect for our area today 11 AM – 8 PM CDT. This portion of the blog will read similar to yesterday’s, but heat safety is important.

Heat indicies from 100 to 110 degrees are possible today. The past couple days have been miserable, we know. The NWS says today will be the “miserablest”. If you have to be outside in this heat, staying hydrated, shade, and air conditioning are key. A great graphic was included in yesterday’s blog about signs of heat exhaustion and heat stroke. It is included again below if you didn’t have the chance to glance over it. read more

First, the rain chances.

The HRRR shows a clear day for us, with maybe a shower or storm popping up in random spots. Mid 90°s temps with a superhumid (for us) airmass — dewpoints in the low 70°s ugggghhh — is plenty of fuel for a pop up storm. Just going to be hard for one to form today. One clue: if it’s storming close enough to us in Kentucky, an outflow boundary will come flying south into town. That could create showers and a few lightningstorms. We’ll watch this and post updates on Twitter. read more

Low Probability Storms Today, with Low-Likelihood Non-Tornado Severe Probabilities (*updated, severe threat dropped)

By on

Heat index up to 97° this afternoon. Same temps as the weekend but dewpoints over 70° will be to blame for making the humidity worse than it was this weekend.

A system of storms will be going through to our north, which could maybe bring us some pop ups in the afternoon/early evening, but it isn’t looking super likely. read more

Heat & Humidity Return

By on

Our cooler temps, lower humidity streak is over. Humidity is up today. It’ll stay there for the foreseeable future. Temps return to normal for August.

No Major Rain Threat

There are a few thunderstorms south of us this morning. They’re moving east and won’t bother us. We may see light rain this morning but the bigger rain and storms should be east of us all weekend. Here is the HRRR model showing the weekend: read more

Rain For Some, Heat For Everyone

By on

Today marks a return to normalcy for August: dewps in the upper 60s and afternoon storms/showers. Highs likely won’t break 90 just yet, but the heat is just getting started.

Rain is back in the forecast today. Model runs are showing activity in the afternoon (see HRRR run below). I say more activity, but we’re not expecting widespread coverage, severe weather, or anything of that nature. Anticipate unpredictable scattered showers/storms here and there, but any action could miss you altogether. Not washout material. Still could delay outdoor festivities. read more

Clear Day Today, Warming Trend Bringing Rain Later

By on

Nothing but dry and warm today. Rain is practically nonexistent in the most current model runs. Some more cloud coverage later today through tomorrow.

HRRR Cloud Coverage, valid Thurs. 1pm – Thurs. 9pm

Highs today are just shy of 90 and dewps in the low to mid 60s. Sticky, but pretty low for August. Tomorrow will be similar, but dial up the humidity a bit (dewps in upper 60s). Highs sneak into the low 90s and dewps hang out in the upper 60s for the weekend. read more
