INDIANAPOLIS — Our time in a comfortable Muggy Meter expires over the next 24 hours with a surge of uncomfortable dew points expected to arrive Friday afternoon.
On the leading edge of this tropical, widely scattered showers and storms emerge...very late tonight and early Friday.
However, much of Friday the radar should be rain-free as the increasingly hot, humid air becomes "capped." The end result will be a hazy, uncomfortably hot afternoon of highs near 90° and heat indices in the 90s.
We'll be monitoring radar closely Friday evening, especially in northern Indiana, for storm initiation along an approaching front. These heavy storms, possibly with severe wind gusts, will creep southward to the I-70 corridor by sunrise Saturday.
Though Saturday shouldn't be a wash-out there will be some heavy storms to open the day and close it after humid heat helps develop more rain.
A lingering front and the muggy air keep daily chances of storms in the forecast into the middle of next week. We're still expecting the well-advertised Saharan dust cloud to arrive here Friday night and cause rather hazy conditions all weekend.
This leads to eerie-looking sunrise/sunsets and possibly poor air quality for sensitive groups.
