Quiet For Now; Changes Coming

Good Tuesday afternoon, today is shaping up to be another hot day across the Ohio Valley. Mother Nature apparently has not realized it is September yet. Temps over the past couple of days have made it feel more like the middle of summer! Fortunately, for the rest of this week, temps should stay below that 90 degree mark as we will have a few chances for storms Wednesday and then again this weekend. Let’s break down the set up for this week.

Today and Tomorrow

The map below from the Storm Prediction Center shows the current weather pattern across the country. The Ohio Valley right now is sitting in between  an area of high pressure to our east and an area of low pressure to the northwest. The high pressure is responsible for the gorgeous weather today. Sunny skies and temps reaching the mid to upper 80s are expected for the rest of the afternoon.


That low will pass by to our north during the day on Wednesday. Fortunately the system is moisture starved and will not produce widespread storms. As the low pushes a front through the region, clouds will increase a little bit and isolated storms will develop. Southern and Central Indiana and areas near the Ohio River in Kentucky stand the best chance to see a pop up storm tomorrow afternoon. These storms are not expected to be too strong or severe. Temps will once again be in the mid to upper 80s with rising humidity values ahead of the front. It will definitely feel like the middle of summer tomorrow.

Thursday through the weekend

After the front pushes through on Wednesday a little drier air will filter into the region. Skies will remain partly cloudy throughout the day on Thursday and temps will rise once again into the low to mid 80s.

The humidity returns Friday as southwest winds ahead of the next weather system kick up. Party cloudy skies and highs in the mid to upper 80s with rising humidity levels will characterize the weather that day. The dry conditions will not last long as rain will move into the region later on Friday night and into the day on Saturday.

As a low pushes by to the north of the region on Saturday a front will slowly push its way eastward toward the Ohio Valley. This system has a lot more moisture to work with than the system for this Wednesday. Thunderstorms, a few on the strong side, will be in the area for a good portion of the day Saturday. The map below from the College of DuPage shows the set up with a cold front draped across the country Saturday evening with plenty of showers and storms.


The rain should come in two waves this weekend. The first wave of storms will come on Friday night and early Saturday morning. Scattered storms will then be in the area during the day. The second wave should come as the front passes though Saturday night. The storms during the day on Saturday and with the second wave have the potential to be strong producing heavy rain, strong winds, small hail, and  lightning. Temps will be tricky on Saturday as it all depends on how widespread the storms are. Areas that see more clouds and storms probably will stay in the 70s all day while areas that see any amount of sun will quickly rise into the 80s.

Overall, not a bad week ahead. This upcoming weekend will not be a complete washout, but make sure to keep the umbrella handy.


Tuesday: Highs in the upper 80s. Sunny Skies

Wednesday: Highs in the mid to upper 80s; lows in the mid 60s. Partly cloudy skies with scattered storms.

Thursday: Highs in the low to mid 80s; lows in the mid 60s. Partly cloudy skies.

Friday: Highs in the mid to upper 80s;  lows in the mid to upper 60s. Getting Humid. Partly cloudy skies. Rain/storm chances going up after sunset.

Saturday: Highs in upper 70s to mid 80s; lows in the low 70s. Thunderstorms. A few may be strong.
