Rain and Cooler Temperatures on the Horizon

Good Afternoon!

It has been quite a toasty one out there today thanks to a upper level ridge centered over the Tennessee River Valley, but an active weather pattern and cooler temperatures are on the horizon. High temperatures for today will top out around 94° with a heat index right around the century mark, 100°. Skies will be mostly clear for the rest of the day with the exception of a few scattered clouds. Tonight will be on the warmer side with lows hovering in the lower 70s with mostly clear skies.

Tomorrow will be very similar to today, except for increasing cloud cover later on in the day thanks to a strong area of low pressure over the northern Great Lakes and eventually moving into the Canadian Province of Ontario tomorrow. The area of low pressure will drive a cold front southeast into the Ohio River Valley. With a lot of moisture and instability in place ahead of the cold front, shower and thunderstorm chances are not out of the question later in the day as the cold front approaches the area. Temperatures tomorrow  will top out around 90° with increasing cloud cover and scattered showers and thunderstorms in the late afternoon and evening hours. Scattered showers and thunderstorms will linger into the overnight hours with a low around 67°.

Temperatures on Saturday will be cooler with highs across Warren County topping out in the middle 70s.
