Summer-Like Weather Returns to Southern KY

wxornotBG 6/29/17: Talking hot, humid conditions and what to expect through the 4th of July weekend.

Well, I hope that you enjoyed the fantastic conditions from last Saturday through yesterday, because we may have to wait for Autumn to see them again. I don’t see a scenario in which we see weather that nice again this summer for that long of a period. Heck, we had highs in the 70s at one point! In late June! That is crazy in and of itself. Today begins a stretch of weather that will be nothing like that.


The high pressure system that had kept our weather so nice Tuesday and Wednesday is making its well advertised move to our east and is placing us well within strong return flow from the south.

This will lead to a major increase in dewpoints today, and that will last into the weekend. Along with this, anticipate higher temperatures than we’ve seen the past 5 or so days. I’m thinking highs will rise into the upper 80s this afternoon, and when that is combined with the high dewpoints, it should yield plenty of instability for storms. I don’t think we’ll see widespread thunderstorms, but isolated storms are possible.

These look to clear our quickly tonight.

Today: Partly cloudy, with isolated thunderstorms. Highs around 87°F. Overnight tonight, anticipate partly cloudy skies, with lows around 72°F.

Tomorrow looks pretty similar, honestly, but a slow moving larger scale system will be gradually approaching our region with plenty of moisture and instability to work with. You know what that means.


Thunderstorms are likely tomorrow afternoon and tomorrow night as multiple disturbances within the upper level flow approach the region. Some of these may just be from modeled convection on the models, but in general, the scenario that may play out makes sense. The afternoon chances are a bit up in the air, but there is the possibility for a weaker disturbance to move into the region. This would likely give us isolated thunderstorms during the afternoon. Either way, look for highs to end up in the mid 80s.

The NAM is showing temps in the mid 80s, which I feel is reasonable to expect for afternoon highs. h/t

The higher chance for storms comes overnight, though. Most of the models at this point develop a strong convective system over Missouri and Illinois during the late afternoon hours, and have it moving towards the region. I don’t think this poses a significant severe weather threat, but it should have heavy rainfall and lightning for sure.

Tomorrow: Partly cloudy, with isolated storms in the afternoon. Highs around 85°F. Overnight, look for mostly cloudy skies, and thunderstorms. Lows around 73°F. 

Saturday looks like a late morning, early afternoon kinda day for interesting weather.


The convective system that moves through on Friday night will likely be pushing eastward as it weakens, leaving us to simmer in terrible heat and humidity into the afternoon. This, however, will set us up for one last go at thunderstorms early Saturday afternoon.

The hi-res NAM develops instability over southern KY by early Saturday afternoon, allowing for thunderstorms to be possible. h/t

If instability develops by early Saturday afternoon, then the cold front will do its work. I anticipate that this will happen. Because of this, the SPC has placed us in a Marginal Risk (1/5) for severe weather.

We have a risk for strong/severe storms on Saturday. h/t SPC

Expect highs in the mid 80s again, with unbearable humidity. The cold front may clear out those dewpoints briefly for Sunday, so enjoy that!


Saturday: Partly cloudy, with scattered storms by the afternoon. Highs around 86°F. Overnight, look for mostly clear skies, with lows around 66°F.
