Today is going to be a scorcher! Air temperatures will be in the middle 90s today and it will be humid, making it feel even warmer. The heat index or the "feels like" will be in the upper 90s or even 100 degrees!
Humidity is directly related to the dew point. Mid-morning dew points have already been increased back to the lower and mid 70s. This is going make it very uncomfortable outside this afternoon.
We are smack dab in the middle of a warm front and a cold front. This area is known as the warm sector. It is a very warm and humid air mass. A cold front is positioned to our NW. It is firing off showers and storms, that are progressing NE. But more storms are expected to develop along the front during the afternoon over the course of daytime heating.
Some of these storms could be strong, but I think we will miss out on most of the action. The Storm Prediction Center has southern Indiana under a "marginal risk" for severe weather. This is the lowest level they provide of six categories. It was also shifted further to the north to exclude some of our counties this morning. SPC's discussion does not even mention the Ohio River Valley. Their focus is northern Indiana.
While severe weather cannot be completely ruled out, we are lacking several ingredients. If any storms become strong or severe, the main threats would be gusty winds, heavy rain and lightning too. The chances for storms will increase as we move into this evening and tonight as the cold front approaches.
Because of all the heat and humidity, we will have decent instability known as CAPE, or Convective Available Potential Energy, around 2000-2500 J/kG.
What we are really lacking is shear or wind energy. It is only about 10-15 kts at the mid-level, which is very weak and not really conducive for severe weather.
Isolated showers and storms are possible this afternoon, but as mentioned above, the chances for storms become more likely throughout the evening, tonight and tomorrow morning, as the cold front approaches. They will stay pretty scattered though.
Once the cold front pushes through, both our air and dew point temperatures will drop. By the middle of the week, it will be significantly cooler after we replace that warm and humid airmass with a cooler and drier one.
How low will we go? And for how long? Find out tonight on WDRB this evening with Jeremy! He will also have the latest information about our storm threats for Monday morning.
I'll keep you posted on social media as well! Find my links below. Have a great rest of your weekend!
