Fall and drought have been nearly synonymous in recent years; 2025 is no different. The September 30 US Drought Monitor, released on October 2, indicated that over 92 percent of the state was categorized as either abnormally dry (D0) or moderate drought (D1), with additional areas classified as severe drought (D2) or extreme drought (D3)[Read More…]

The last week has caused many to struggle with whether to turn the heat on inside. Mornings have been quite chilly, and I am guessing several readers may have also struggled with the decision to wear a jacket as they started their workday. These are tough decisions, no doubt. Several data sources have suggested we[Read More…]
If you have any stakes in agriculture, you may have noticed a fairly rapid drying trend as summer has come to a close. According to the U.S. Drought Monitor on September 2, 76 percent of Indiana is considered abnormally dry—up from just 26 percent one week earlier. Moderate drought conditions have also expanded from less[Read More…]
With brute and sudden force, the atmosphere is doing its job: acting like a fluid. Weather is not a precise science, which means the atmosphere is constantly shifting. There tends to be some sort of pattern shift come mid-late August, and it looks like it’s just about here. Temperatures are on their way down, as[Read More…]
The Midwestern Regional Climate Center (MRCC), with support from the United Soybean Board, has launched the Ag Climate Dashboard — a centralized digital hub offering streamlined access to integrated climate and agricultural data and decision-support tools for producers, advisors and researchers in the Midwest. Designed to support on-farm decision-making, the Ag Climate Dashboard offers up-to-date weather data, National Weather Service[Read More…]
The heat and humidity have returned to the state, as heat indices soared above 100°F on Wednesday and Thursday (July 23-24) this week. The National Weather Service issued heat advisories that spanned from northeast Texas to northeast Ohio on July 24. Over the last 7-day period (July 16-22), average temperatures ranged from near normal in[Read More…]
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[Read More…]
I couldn’t think of a better title this week, thanks to the hot weather we’ve been experiencing and the song by Arrow. While some people enjoy the heat and humidity, I must admit that I don’t find it overly pleasant. Over the past few days, average temperatures have ranged from 6 to 13°F above normal,[Read More…]
We’ve made it! Meteorological summer started on June 1, but the official start of summer isn’t until June 20. The days are longer, temperatures have risen, and my allergies are in full swing. I let the dogs out last night, and there was still quite a bit of light in the sky just before 10:00[Read More…]
Welcome to the start of Hurricane Season that runs from June through November each year. Why would Indiana care about hurricane season? Certainly, by the time any hurricane might impact the state, it will have been greatly downgraded to what is called an extratropical (i.e., poleward of the Tropic of Cancer (23.5° north latitude)) storm[Read More…]
Precipitation in May has varied tremendously, but most of the state has generally been on the dry side. Areas from Vermillion and Parke Counties to Lake Michigan have received between 25% and 75% of the normal precipitation through May 27 (Figure 1). Conditions were dry enough that thunderstorm winds on May 16 prompted the National[Read More…]
The last few weeks have been on the drier side, particularly for northwestern and west-central Indiana (Figure 1). While temperatures have been seasonal, they are still gradually increasing as we approach summer. Therefore, evapotranspiration rates are starting to increase. This has resulted in the U.S. Drought Monitor classifying much of northern Indiana as Abnormally Dry[Read More…]
Midwestern farmers have faced a buildup of pesticide resistance in pigweeds (waterhemp and Palmer amaranth), highlighting the importance of scouting to detect weeds early in their growth stages. Otherwise, weed escapes are a common issue as herbicides lose their efficacy when weeds are allowed to grow long enough into their growth cycle. The Midwestern Regional[Read More…]
Despite the wet start to the month, the entire state saw less than 50 percent of normal rainfall from April 10 to 16, and in some cases, less than 10 percent of normal rainfall (Figure 1). This was helpful, especially as some locations still deal with river flood warnings and ponded and saturated fields. This[Read More…]
Indiana has already experienced several tornadoes this year with more certainly to come. Of course, this is not unusual since Indiana is often considered on the far northeastern edge of “Tornado Alley”. Tornadoes get their energy from the battle between the cooler, drier Canadian air moving southeastward and the warmer, more humid air coming north[Read More…]
Spring field operations have already begun across the state, including tillage, anhydrous ammonia applications, and even some planting. Temperatures look up from here, but we cannot rule out periods of cooler conditions between now and May that could impact crop emergence. As of March 18, 2025, the 7-day average 4-inch soil temperature at the Purdue[Read More…]
While our daytime highs across the state were in the upper 70s, our nighttime lows have been in the 30s (even into the upper 20s) in some places. This could get us thinking about the timing of the first frost and freeze events of the season, when the 7-day average 4-inch soil temperature falls before[Read More…]
While our entire state did not receive the amount of rain from the remnants of Hurricane Helene compared to other states, most of Indiana did receive at least an inch of precipitation over the past few weeks with some southern counties receiving over five inches (Figure 1). General impacts have been greener lawns (don’t put[Read More…]
As September begins, we officially welcome meteorological fall. While the autumnal equinox isn’t until September 22, the past few mornings have already brought a crisp, fall-like feel to the air. Around town, fall decorations are starting to appear, and a few maple trees are showing early hints of color. My wife, however, is eagerly waiting[Read More…]
Several weeks ago, Indiana received enough rain to eliminate drought across the state, leaving behind just a few counties in Abnormally Dry (D0) status. Fortunately, this week has been relatively quiet, allowing many areas to alleviate flooding issues. The U.S. Drought Monitor kept those Abnormally Dry areas nearly the same this week (Figure 1), so[Read More…]
