High Pressure Breaks Down

Good morning! As the ridge of the high we've been dealing with shifts south and east, highs will be at their peak today. Our average is 80 to 81 degrees and most locations will find highs right around 90 to the lower 90s. We will be close, but I think we will make it by without beating the record of 93 degrees set back in 2011. Looking below, even with warm temperatures the past several days we are still warming compared to this time yesterday. 

As mentioned, forecasted highs will be near 90 for most of East Tennessee with the southern valley likely finding the lower 90s this afternoon. Depending on how much cloud cover we see later today could impact afternoon highs. Given the trend, I am comfortable saying 90 is likely for most.

Working ahead, showers begin making an appearance. A low moving through Canada will bring a cold front across the region Thursday. This will be weak and only bring isolated to scattered showers. This will be followed by a stronger low moving across the Ohio Valley and Great Lakes region bringing moderate to heavy showers and thunderstorms for Friday. This will mainly be an afternoon to evening event, but a few showers will linger into the weekend as well. Overall, this will help knock temperatures back to near average with highs Saturday to be in the mid to upper 70s. 

A mix of cloud cover and sunshine will again be the story today with highs very warm. Continue to practice heat safety will drinking plenty of water and taking breaks throughout the day. Have a  good one and stay cool!
