The heat wave is underway across Greater Cincinnati and the Tri-State, and the morning will offer only limited relief before the heat intensifies again Tuesday. Skies will remain mostly clear overnight with temperatures staying quite warm, and those increasingly warm nights are becoming part of the story as this stretch of heat continues.
High pressure in the middle levels of the atmosphere is slowly shifting east toward the Tri-State, helping temperatures climb a little higher each day. Tuesday will be sunny and hot, with afternoon temperatures reaching the low to mid 90s. More importantly, the heat index values will hit around 100, so the combination of heat and humidity will make conditions especially uncomfortable for anyone spending extended time outdoors. A HEAT ADVISORY is out through Wednesday at 11 pm.
Wednesday brings very little change, with mostly sunny skies and temperatures remaining in the mid to upper 90s as the high-pressure ridge continues to control our weather. By Thursday, that ridge begins getting pushed slightly farther south as a front settles across the lower Great Lakes. Most of the Tri-State remains hot, with highs again in the low to mid 90s, and areas farther south could experience their hottest day of this stretch.
There is also a low chance for thunderstorms Thursday afternoon and evening, mainly across northern portions of the region. A more meaningful change arrives Friday as cooler air high in the atmosphere moves southeast out of Canada. That will push the ridge back toward the Plains and drive the front into and most likely through our area. Friday brings the greatest chance for thunderstorms, along with temperatures finally beginning to come down. Even then, I would expect temperatures to remain above normal, so while the worst of this heat wave may begin easing late in the week, summer heat isn’t finished with us yet.
