Indianapolis has been experiencing high temperatures for the third day in a row, with the airport recording a high of 92°. The same goes for most areas in Central Indiana, with heat indices reaching the upper 90s to over 100°. Fortunately, there is some relief in the form of storms and a cold front heading towards our region. This pattern is expected to repeat itself twice over the next week.
Late tonight and early Sunday, we can expect the arrival of storms.
Central Indiana is currently not under a severe weather threat, but it’s important to keep an eye on the storms developing in Iowa and Illinois on Saturday evening. Although these storms are expected to weaken as they move southeast into Indiana, there is still a possibility of isolated damaging wind gusts in some of our northwest counties. However, for the most part, it will be a line of weakening storms that will bring some downpours, thunder, and lightning to our area.
It appears that this event will occur late at night, with our northwest counties experiencing it around 2-3 AM and our southeastern counties seeing it end no later than 8-9 AM. Once the system clears out, we can look forward to a dry day with clear skies. While there is a chance of an afternoon shower, the likelihood is low.

The intense humidity levels take a brief hiatus.
As the front moves out of Central Indiana, we can expect a return of northwest flow. This will cause a slight decrease in humidity levels on Sunday and Monday. Despite this, the high temperatures will remain slightly above average, hovering in the mid-to-upper 80s. While there may be a few areas that reach 90°, it won’t be as widespread as it has been in recent days.
Tuesday will bring about hotter temperatures and increased humidity, with the possibility of storms on the horizon.
On Tuesday, the expanding hot dome will cause a surge in humidity levels. The expected highs in the lower 90s will bring heat indices close to 100° in various locations. This will create an unstable atmosphere filled with moisture that will pave the way for storms and a cold front on Tuesday night and Wednesday.
As we approach the upcoming days, our team will closely monitor any potential severe threats that may arise. In the event of such a threat, it is possible that we may experience damaging winds. Based on our current analysis, it appears that this threat may occur during late night on Tuesday and continue into the daytime on Wednesday. While there may be a few waves of precipitation during this timeframe, Tuesday daytime is expected to remain dry, albeit hot and humid. It is important to note that we do need the rain, so any precipitation that does occur will be much appreciated.
Following the aforementioned period, the weather will become calm again, accompanied by a slight drop in temperatures. What’s noticeable is the lower dew points, which will be evident from next Thursday and throughout the early days of next weekend. Although there might be a few chances of rain, it’s too early to predict any specifics at this point. However, the trend indicates that the temperatures will still be above average as we approach the end of June and move into July.
