Muggy air fuels storms Monday and Tuesday

You can definitely feel the difference in humidity this afternoon, with the Muggy Meter now well in the uncomfortable range. This is due to an influx of gulf moisture as dew points are 15-20 degrees higher than 24 hours ago. Sticky stuff is here to stay for the next 48 hours and will fuel possibly severe storms and areas of heavy rain Monday and Tuesday.



Another byproduct of the humid air is uncomfortable lows near 70 in the morning. While isolated showers are possible this evening, it appears the best chance of rain and storms will be after midnight and just prior to sunrise. We’ll need to monitor storms in the western Great Lakes to see if they’ll be able to hold together and make it into central Indiana after midnight and before sunrise. It’s questionable a this point, but don’t be surprised to hear some rumbles of thunder overnight.



Strong to severe storms are possible Monday as a cold front approaches central Indiana… and much of the state is under a warranted Slight Risk. With tropical air in place, areas of heavy rain are likely in any storms that develop. All modes of severe weather are possible tomorrow, but there is much uncertainty on time/location of storm initiation after early morning storms and cloud debris. Stay weather aware tomorrow.


An unsettled pattern remains in place Tuesday with storms likely and more heavy rain to start the day.


The aforementioned front settles south of the Ohio River mid-week… allowing less humid air and sunshine to return Wednesday into Friday. Have a great evening – Sean Ash
