Friday will again be below average with highs just below 80. With more cloud cover than Thursday it will feel a bit cool for the season. We have an isolated rain threat that I will now break down:
A warm front is slowly approaching. Ahead of it, we'll increase clouds throughout Friday morning.
We could see a light shower this morning, but it will be Indianapolis or west. East of the city will stay dry during the day.
The storms look potent as they approach from the west, but that's because the air is much more moist out that direction. Back in central Indiana we have much drier air, so storms will weaken significantly as they get to us. That's why we keep rain chances so low during the day.
We can't rule out a stray shower for Symphony on the Prairie Friday night, but it will likely go on because so little rain is expected.
As moisture builds in, we'll bring up the rain threat for Saturday--specifically in the morning.
Storms roll in very late Friday night. We could see storms roll through as early as 4 a.m. and into Indianapolis by 6 a.m. Storms will be exiting by noon, so just plan on waking up to thunder. Outdoor afternoon and evening plans will be good to go. We could get another storm through Saturday night.
Saturday AM storms will bring a quarter inch of rain or less to the area.
Heat and humidity pour in after the passage of that warm front. We could hit 90 by Sunday.
