Hot, muggy days in Indiana can get old, quickly! With all the rain lately, and higher humidity, it has been a challenge to get any nighttime relief.

Precipitation forecasts for Indiana over the next 7 days (through late Thursday, July 24) are calling for close to 3 inches (Figure 1).
One heat wave down, more to come.
One heat wave down, more to come. It is summer, though, so aside from expecting plenty of hot days, the things to be more concerned about is reference (or potential) evapotranspiration (ET) significantly exceeding precipitation that would ultimately cause drought-related impacts. The National Weather Service provides a 7-day forecasted reference ET product as well as a 7-day forecast for total precipitation amounts. From these resources, it looks like across Indiana, approximately 1.5” of water is expected to be lost over the next 7 days and anywhere from 0.10” to up to 1.5” of precipitation will be received (Figure 1). This implies a water deficit for most areas – which is not unusual throughout Indiana summers. The concern comes when that deficit becomes much greater than normal. Concerning drought, the U.S. Drought Monitor continues to place northwestern Indiana in the Abnormally Dry (D0) category with two isolated areas within that zone[Read More…]
June 20, 2025, marks the summer solstice in the northern hemisphere. This is more an astronomical (i.e., planetary and orbital, not necessarily huge) event rather than meteorological. This is the date when the north pole is leaning most directly toward the sun due to its tilt relative to earth’s solar orbit throughout the year. Because of this, the length of daylight within a 24-hour period is greatest on this day for all locations north of the equator. More daily daylight means more solar exposure and therefore greater surface heating and temperatures. Of course, we’ve been working up to this moment for a while (since December 21, 2024) and we’ve already been experiencing warmer temperatures. Mother Nature is going to really show off her solstice spirit, however, with extreme high temperatures expected by the end of this weekend into next week. Over the last 30 days or so, average temperatures across[Read More…]
Welcome to the start of Hurricane Season that runs from June through November each year.
Southern Indiana took the lion’s share of precipitation in April with some locations getting over twice the amount of rain than normal for that month.

What do you think of when you hear the word climate? I would guess answers would range from ‘average weather conditions’ to ‘hot, muggy summers’ to ‘climate change’ to ‘environmental policies and politics’. What a range! Fields of climate can vary from paleoclimate studies (e.g., ice cores and tree rings), to applied climate science (e.g., architectural design and vector-borne diseases like West Nile Virus and Malaria), to climate modeling (e.g., lots of physical equations and computers), to climate change (e.g., ‘but the polar bears, Daddy!’), to climate services (e.g., data translated into information). Among all this diversity, the common thread is the consideration and correlations of what has occurred in our atmosphere historically to better understand and prepare for current and future decisions. Since the late 1800s, our country has had an organized effort to collect observational data (e.g., temperature and precipitation) at hundreds of locations so we can monitor[Read More…]
There is the common adage “April showers bring May flowers”. Apparently, Mother Nature utilized a rather liberal definition of “showers” last weekend and the end of last week by dumping over seven inches of rain in southern Indiana.
