INDIANAPOLIS — As expected, central Indiana is in the midst of dangerous heat indices peaking in the 100°-105° range Sunday afternoon and again Monday. We're advising you to limit outdoor time if possible and stay well hydrated with plenty of breaks if you can't limit your time outside.
The Muggy Meter will remain oppressively humid until the middle of this week with dewpoints in the 70s between now and Tuesday afternoon.
This will lead to another night of muggy lows in the 70s and sultry conditions into Monday afternoon with highs near 90° and heat indices 100°+.
Spotty downpours will linger around central Indiana until around sunset this evening as the atmosphere stabilizes for the remainder of the night.
It's a rinse and repeat set-up Monday, but with the expectation of greater downpour and storm coverage in the afternoon/evening.
Organized severe weather isn't expected, but with highly humid air in place, the potential for excessive rainfall rates continues.
The latest data suggest the axis of heavier rain potential will sink into southern Indiana on Tuesday after a likely damp start around Indy that day.
This is part of a step-down process in the Muggy Meter from oppressive Monday, not as Wednesday, to flat-out comfortable air Friday into next weekend. That's when we'll be able to give the A/Cs a well-deserved break at times and enjoy some refreshing breezes.
