Warm, Dry Weather Causing Abnormally Dry Conditions Across Indiana

Indiana has been very dry the last several weeks (Figure 1) and conditions are starting to show in lawns and fields. This dryness has been exacerbated by low humidity and warmer temperatures (Figure 2). After a nice respite this past weekend, temperatures will start rising again into the weekend, but may not seem too uncomfortable with humidity remaining low at the front end of that warming period. The short-term forecast is calling for a slight chance of precipitation over the next seven days, but expect it to be light and spotty. The good news is the climate outlooks for the rest of June is showing increased probabilities of above-normal precipitation (Figure 3), … but will it be enough to compensate for the deficit we have been facing these past few weeks?  It is too early to know for sure, but there are no major storm systems on the horizon, nor jet stream patterns that indicate a lot of precipitation is on its way.
