Today’s high temperature of 93 tied the record for Sept. 9 and was “the second hottest day of the year,” according to Storm Center 7 Chief Meteorologist Jamie Simpson.
“It is also the 13th day we hit at least 90,” Simpson said.
Overnight lows will be in the upper 60s, but wow 90s will likely be reached Tuesday and possibly Wednesday.
“If we don’t get too many clouds and showers Wednesday we should hit 90 also. That would make a September heat wave,” Simpson said.
Tuesday will be more humid, raising the heat index to the upper 90s, and there may be a stray shower or pop-up thunderstorm.
Wednesday will have a better chance for pop-up showers and thunderstorms in the afternoon.
“A cold front approaches Wednesday night and that may increase chances for some rain then,” Simpson said.
The cold front passes through Thursday morning and the most significant rains may develop south of Dayton in the afternoon. Temperatures will rise from the upper 60s to the lower 80s.
Friday should have lots of sun with low humidity, with temperatures starting in the mid 50s and afternoon highs near 70.
Saturday should have even lower humidity and few clouds, with temperatures starting in the mid 40s and rising to about 70.
“I’m guessing local apple merchants will have a good day Saturday,” Simpson said.
Sunday is expected to be partly cloudy and a bit warmer, with lows near 50 and highs in the mid 70s.
