The episode as NWS IND wrote it up.
A gradually dissipating complex of thunderstorms moved across north central Indiana during the morning hours of the 23rd, causing widespread minor tree damage. A gust front associated with this complex of storms then pushed to the south and caused additional tree damage across the Indianapolis metro area. Damage from this gust front was most severe near Carmel, IN.

Area Forecast Discussion National Weather Service Indianapolis IN 740 AM EDT Sat Jul 23 2022 .Forecast Update... Issued at 740 AM EDT Sat Jul 23 2022 ...Severe Thunderstorm watch until 18z for portions of north central Indiana... ...Heat Advisory in effect today across portions of Central Indiana... An MCS developed across northern IL/IN overnight and is moving ESE this morning. Latest trends suggest this MCS may move far enough south to impact portions of north central Indiana. ACARS soundings show strong low level inhibition remains across the region which could limit the damaging wind potential. Although if the MCS were to make it into northern parts of the CWA, moderate MUCAPE and 30-35kts of 0-6km bulk shear would support an isolated damaging wind/severe hail threat. Hot and humid conditions are likely today as temperatures rise into the low to mid 90s. Dewpoints in the 70s will make it feel rather uncomfortable with heat indices approaching 105 degrees, especially across southwest portions of central Indiana. Make sure to drink plenty of water and take breaks when needed. && .Short Term...(Today through Sunday) Issued at 259 AM EDT Sat Jul 23 2022 A shortwave trough is approaching the region this morning. This shortwave along with a 30-35kt LLJ has aided in the development of thunderstorm clusters from Eastern Iowa to southern Michigan. The bulk of the convection developing overnight should remain north of the area. 850-300mb flow, a strong instability gradient over northern Indiana/southern Michigan, and the strongest 850mb winds located to our north suggest these storms will mainly stay out of the CWA. Decided to keep chance POPs north of I-70 this morning due to some uncertainty with how convection develops over the next few hours. ACARS soundings show strong low level inhibition across the area thanks to radiational cooling and subsidence. Due to this, no severe weather is expected this morning as this strong surface inhibition would likely limit any damaging wind threat. Any leftover clouds from potential convection in the morning should clear out by the afternoon, allowing for temperatures to warm into the 90s. Sunny skies and moisture advection will allow for further destabilization and gradually erode the cap. Strong instability, deep moisture, and a weakening cap through the day may lead to a few showers and thunderstorms across northern counties this afternoon. An isolated severe thunderstorm cannot be ruled out with damaging wind gusts and isolated large hail being the primary hazards. Highs in the mid 90s with dewpoints in the 70s will lead to hot and uncomfortable conditions today... especially over southern counties where heat indices may approach 105F today. Quiet weather is expected overnight Saturday before another upper level impulse approaches central Indiana during the latter half of the day on Sunday. Southerly flow ahead of the approaching system will limit diurnal cooling Saturday night with lows in the mid 70s. A cold front associated with the upper level impulse is expected to produce scattered showers and thunderstorms Sunday afternoon. Strong instability and 30-40kts of effective bulk shear should support organized thunderstorms. Strong to severe thunderstorms will be possible with the potential for damaging wind gusts and isolated severe hail. Guidance suggest steepening low-level lapse rates and a 40kt LLJ could lead to 25-30mph wind gusts through the day. Look for another hot and humid day on Sunday before storms move in during the afternoon. && .Long Term...(Sunday night through Friday) Issued at 259 AM EDT Sat Jul 23 2022 Highlights: * Periodic chances for precipitation and possibly thunderstorms throughout the extended * Gradual temperature decrease as a boundary moves through next week. Extended Pattern Overview: Second half of the weekend will feature the persistent high amplitude ridge over the North Atlantic, which has continued to bottle-up the mid-lvl shortwave over Hudson Bay for the past few days. Upstream across the Pac-NW it appears the development of a ridge is beginning to show-up as 500mb heights will start to become elevated. Ensemble datasets have been consistent with minimal noise amongst membership in a amplified ridge over the AK region early next week. Mon/Tue the flow in the mid-levels for the Great Lakes/Ohio Valley will be quasi-zonal, supportive of a somewhat progressive pattern. This will likely allow the possibility of a frontal boundary to slide south across Indiana, but then become sluggish along the Ohio River. With the southern stream atmosphere rather benign, or lack of any organized systems, this would also indicate the boundary will be tough to push too far south of the Ohio River. Wed/Thur the boundary should push back north, as the Hudson Bay shortwave kicks a lobe of vorticity south into the Western Great Lakes/Upper Midwest and will help to pull the boundary north as a warm front across Central Indiana. Simultaneously upstream further amplification to the ridge is progged to occur. Guidance has been inconsistent with placement and timing of a surface wave for the Great Lakes region Wed/Thur, which will dictate timing of the frontal boundary sliding back south as a cold front later in the week. Fri/Sat still appears to be the best days of the extended, with a quasi-northwest flow to the atmosphere. The North Atlantic block will relax and allow the Hudson Bay vort max to push east, but this will allow start to allow the Pac-NW ridge to nudge east as well. This suggests the weak troughing poised to cover the Ohio Valley/Great Lakes will be brief, with a return to above seasonal temps beyond the current extended periods. Daily Extended Conditions: Mon/Tue: Frontal boundary will traverse the region, so increased cloud cover Mon coupled with periodic chances for precipitation and possibly thunderstorms will keep temps more seasonal in the low/mid 80s. Tue will be a challenge for temps at this range as it will hinge on placement of the frontal boundary. Ensemble data is still indicating a higher confidence that the surface ridge will still be overhead until late Tue. This scenario would indicate one more day of pleasant conditions with highs in the low 80s with a chance for precipitation likely late in the day as diffluent flow pushes east. Wed/Thur: Flow becomes zonal in the mid-levels and with a surface wave navigating the Great Lakes, which should assist with pulling the frontal boundary north as a warm front early Wed and a southwest surface flow. This will bring warm/humid conditions back to Central Indiana along with periodic chances for precipitation and possibly thunderstorms. While the current setup would support temps moderating back to the upper 80s perhaps around 90 Wed/Thur, given the abundance of cloud shielding and periodic chances for precipitation, it's conceivable to think enough shielding could keep temps down in the mid 80s for a longer period. Fri/Sat: With a more progressive pattern late in the week, this should usher in diffluent flow to the region and a period of cooler/dry conditions. Current data and forecast would suggest temps will be peaking around 80 to the low 80s. But this will be short- lived as the height rises upstream will be knocking on the doorstep of the region late in the extended. && .Aviation...(12Z TAF Issuance) Issued at 639 AM EDT Sat Jul 23 2022 Impacts: * VFR Conditions are expected this TAF period. * Very Low Confidence for an Isolated Thunderstorm after 14Z in the vicinity of LAF. Discussion: Little overall change since the previous discussion. Guidance has struggled to handle the complex of showers and thunderstorms over Northern Illinois and Southern Wisconsin overnight, so confidence that the current area of precipitation will continue to progress south towards Central Indiana airfields is low. The best timing for any thunderstorms appears to be late this afternoon into the evening hours, although confidence is still low on timing and placement. With that being said have opted to continue with no mention in the current TAF about precipitation. VFR conditions and southerly winds to slightly southwesterly winds around 7-11kt can be expected. && .IND WATCHES/WARNINGS/ADVISORIES...
