Sunshine, heat, and humidity for another day making for nice summery weather. Temperatures are topping out near 90 degrees again this afternoon with dew point temperatures in the low 70s. It’s uncomfortable, but not enough to keep you inside. The MaxTrack doesn’t have much to look at today, but that will chance shortly.
We started the week with building high pressure. This brought back the sunshine, kept the storms (mostly) at bay, and ramped up the heat and humidity. This was sort of like a blast of midsummer weather. Changes will become apparent over the next 24 hours as that high pressure begins to break. You’ll notice cloud coverage popping up quickly through the day Thursday along with a better chance for scattered showers and storms. A weak trough will aid in thunderstorm development. Heavy downpours, lightning, and gusty winds expected. We’ll have the same effects on Friday. Temperatures will still be warm, and humidity will remain in place, but the 90s will turn into the low to middle 80s. Saturday will be a completely different story. The powerful hurricane Laura will be rolling onshore between the Louisiana/Texas state line early Thursday morning. Over the entire day Thursday and Friday, it will curve northeast and eventually east into the Cumberland River Valley. Laura will weaken severely before it arrives in Kentucky. Still, it will bring tropical moisture and some wind with it. Expect most of Saturday to consist of persistent rain with breezy conditions. Thunderstorms are likely to develop in the afternoon. The remnants of Laura will move on quickly and we should be seeing a reduction in rain and wind as early as Saturday night and early Sunday morning.
