The episode as NWS IND wrote it up.
During the afternoon hours a complex of thunderstorms crossed into Indiana from Illinois. A widespread swath of 65 to 75 mph winds occurred from central Terre Haute as far south as Sullivan, with the southeastward path then continuing into Clay, Owen, Greene, and Brown Counties before gradually beginning to weaken as it entered Lawrence and Jackson Counties.
The southern side of Terre Haute saw numerous large trees and power poles snapped or uprooted with widespread property damage to cars and homes along with thousands of power outages. Clay City and Jasonville also were areas of more concentrated damage with additional trees downed. The Bloomington ASOS measured 78 mph, which lined up with the town of Bloomington seeing the most significant damage from this event with a large swath of the town seeing widespread tree, power pole, and property damage.
Spotters later measured a 75 mph wind gust in far southern Brown county where additional tree damage was found but after this point the storm complex gradually weakened with the last damage noted in the Seymour area as the complex moved into an air mass that was more stable following weaker thunderstorms that had occurred earlier in the afternoon. The storm complex exited south central Indiana around 4:45 PM for a total event time of 2 hours between Terre Haute and Seymour.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Indianapolis, IN wrote its last area forecast discussion before the first event at Jun 25, 8:57 AM EST, 1 hour 48 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Indianapolis IN 957 AM EDT Tue Jun 25 2024 .KEY MESSAGES... - Thunderstorms will be around at times today into Wednesday. Some severe storms are possible, especially this afternoon. - A good amount of uncertainty remains in the specifics of the storm chances today into tonight. - Today will likely be the warmest day of the week. - A brief respite from heat and humidity Thursday before another warm up and additional storm chances this weekend. && .FORECAST UPDATE... Just a quick update this morning as we wait for storms across northern Indiana to propagate southward. Trimmed PoPs a bit and refined the edge in an attempt to estimate the arrival of the aforementioned storm complex. CAMs are not, and will not be, handling this system well as it has a mature cold pool. The system should propagate into the low-level winds which are largely from the south- southwest. The system is currently outflow dominant, and is expected to remain so as shear decreases with southward extent. Upshear Corfidi vectors diminish in magnitude with southward extent as well, so the system may slow down a bit as it heads southward this afternoon. This may pose a flooding hazard later on, especially on the southwestward flank of the system. The threat for severe weather (damaging winds and hail) also remains present as CAPE is large and lapse rates are steep. The evolution of this system is expected to affect subsequent development later this afternoon and evening. && .SHORT TERM (Today and tonight)... Issued at 302 AM EDT Tue Jun 25 2024 Forecast remains challenging for the short term, as details will be mesoscale driven. Each potential cluster of thunderstorms may impact future ones, which results in a low confidence forecast with multiple potential outcomes. CAMs often struggle with weakly forced scenarios, so use caution in using individual CAM output. Bottom line: There will be chances for thunderstorms throughout the short term, some of which could be strong to severe this afternoon depending on available instability. Hot temperatures will return, but how hot depends on convective development. Early this morning... An area of thunderstorms had developed across northeast Illinois, on a temperatures/moisture gradient along an approaching airmass. The storms were moving south/southeast along the gradient. As the airmass works its way east during the early morning, these storms should begin to move east as well. Stronger winds aloft remain across northern portions of the area, so the storms should hang on longest there. Uncertainty remains though on the speed that the area of storms moves east. Will have some chance PoPs, mainly across the northern forecast area for now. Today... The temperature gradient aloft should be east of central Indiana by the start of the today period, but some warm advection will still be ongoing. There will likely be some clouds around from the earlier convection, and some of this convection may still be ongoing, but in a weakened state. Meanwhile, the tail of some additional upper forcing currently creating storms across Wisconsin, will be moving into Indiana from the north. Whether it can generate more convection will depend in part on what the early morning convection does. More early convection/clouds will lead to lower odds of convection with this forcing and vice-versa. There are multiple scenarios that may play out, but feel that these two are the most likely: 1) Clouds/dying early morning convection inhibits additional development for a while today. Afternoon convection develops along old outflows and any upper forcing that moves in. Mainly scattered storm coverage. 2) Clouds/early morning convection dissipate quickly. Instability builds and a line of storms moves south across the area from the initial upper forcing. These storms will intensify during the late morning into the afternoon as they move south across the area. Scattered to numerous coverage would occur. Either scenario could result in strong to severe storms in the afternoon given the potential instability that could build. The primary threat would be damaging winds. Will keep PoPs in the chance category given the high uncertainty. The other concern today will be the heat. 850mb temperatures will be above 20 degrees C, leading to the potential of mid and upper 90s. Dewpoints will be around 70 to the lower 70s, leading to potential heat indices near 105 in the southwest forecast area. If confidence were higher in cloud cover/convection, a Heat Advisory would be needed in the far southwest. However, uncertainty is much too high. May issue a Special Weather Statement for heat. Tonight... Thunderstorm chances will continue tonight. Storms may be ongoing early in the period from the afternoon convection, depending on its eventual timing. Overnight, a cold front will approach from the north, along with some additional upper energy. This will result in more shower and thunderstorm development, especially north. However, once again, uncertainty remains on the amount of instability that will be available due to earlier convection. Will go with high chance category or likely category PoPs tonight, with highest PoPs overnight when the cold front approaches. Low temperatures will be from around 70 to the lower 70s. && .LONG TERM (Wednesday through Monday)... Issued at 302 AM EDT Tue Jun 25 2024 The long term period will see temperatures fluctuating between near normal and above normal with multiple chances for showers and storms as numerous system pass through the region. Wednesday morning will start off with showers and thunderstorms along a cold front pushing south/ southeast through the area. As this will be an outflow influenced frontal environment, can't rule out the possibility of a few stronger cells forming and potentially producing damaging winds and maybe some hail as the front exits. There is some uncertainty on when rain will end as some models indicate redevelopment could occur in the evening to overnight hours. Overall, expecting a bulk of the rain to come to an end by the evening to early overnight hours Wednesday. Behind the front, cooler temperatures and high surface pressure will move in allowing for a pleasant and relatively dry day Thursday. Unfortunately, this nice weather will be short lived as heat and humidity return for the weekend. The end of the long term period will see multiple chances for precipitation but models lack agreement on exact extent and timing. Currently best precip chances look to be Saturday, but could arrive as early as late Friday. This will likely be followed by a dry break before another system potentially arrives around Tuesday. && .AVIATION (12Z TAF Issuance)... Issued at 646 AM EDT Tue Jun 25 2024 Impacts: - Isolated convection this morning, then chances for convection anytime thereafter. - Wind gusts over 20kt mid morning through the afternoon Discussion: Low confidence forecast due to high uncertainty in convective development through tonight, as each round of convection will have an impact on the next. Isolated storm west of KLAF near 11Z will continue to slowly move southeast. It may not make it to KIND as atmosphere is less favorable there. Other storms will develop/move in later this morning or early afternoon north and eventually move south. More storms will develop tonight. Given the low confidence, continued with VC or PROB30 at all sites. Outside of convection, VFR conditions are expected. && .IND WATCHES/WARNINGS/ADVISORIES...None. && UPDATE...Eckhoff SHORT TERM...50 LONG TERM...KF AVIATION...50
