*An Air Quality Alert is in effect for the Miami Valley on Monday. Pollutants trapped near the surface will make breathing difficult for this with asthma and respiratory illnesses. We suggest carpooling, combining trips, and waiting to refuel or mow the lawn until after 8 p.m. or before 8 a.m.*
Sunday night will still feel quite tropical with temperatures in the 80s well after sunset. Overnight, lows will only dip to the mid-70s. This is the warmest stretch of overnight weather so far this year.
Monday morning will be warm and muggy with temperatures already in the 80s by 10 o'clock. Afternoon high temps will reach the low-90s again, with heat indices nearing 100 degrees. Plenty of sunshine will be available, meaning that a pop-up shower cannot be ruled out. However, most of us stay dry.
A greater chance for showers and thunderstorms arrives Tuesday. Despite this, another hot afternoon is coming with highs in the upper-80s. Showers and storms are still likely Wednesday, especially during the first half of the day. Highs top out in the mid-80s, and a dry evening is expected. Thursday is the pick day of the week with highs in the mid-80s, lower humidity, and a partly cloudy sky.
As we get ready for the Vectren Dayton Air Show, our chance of thunder increases. Pop-up storms are possible Friday evening with temperatures in the mid-80s. Saturday will feature a few scattered thunderstorms, but dry times during the day. Sunday will have less of a chance for rain, but isolated afternoon thunderstorms cannot be ruled out.
The best window of opportunity for the Air Show will be the morning, both days. Afternoon highs next weekend will be in the upper-80s, so make sure to wear sunscreen and drink plenty of water.
