The episode as NWS IND wrote it up.
A lingering, small upper level short wave slowly departing the Midwest, combined with adequate daytime heating to promote scattered afternoon showers across much of central Indiana with a few embedded non-severe thunderstorms.|One thunderstorm crossing Jennings County produced a cloud-to-ground lightning strike that struck a tent in the County Squire Lakes neighborhood northwest of North Vernon.
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 Aug 2, 10:36 PM EST, 22 minutes earlier. Its key messages:
Area Forecast Discussion National Weather Service Indianapolis IN 1136 PM EDT Fri Aug 2 2024 .KEY MESSAGES... - Clearing tonight with patchy fog overnight into early Saturday morning - Partly Cloudy and warm on Saturday - Aside from patchy early AM fog this weekend...mainly rain-free, yet humid and marginally hot conditions will continue into next week && .FORECAST UPDATE... Issued at 944 PM EDT Fri Aug 2 2024 Latest lightning data was not showing any activity across central Indiana as LAPs and SPC mesoanalysis data was indicating decreasing instability with the boundary cooling post sunset. Meanwhile, radar data was only showing isolated cells over the lower Wabash Valley, some still putting out moderate rainfall as PWATS were still on the order of 1.6 inches which is above normal. Meanwhile, a larger area of convection was pivoting southeast on the back side of the upper low, which was moving east across west central Ohio per H20 vapor imagery. The low will continue to move east and in additional to nocturnal boundary layer cooling should put an end to the showers by or shortly afternoon Midnight. Fog and or low stratus could be an issue overnight based on small temperature and dew point depression differences along with some clearing associated with the ridge getting closer. Hi-RES soundings indicate some drying aloft and in the boundary layer which should mean the fog will be relatively shallow and should burn off shortly after sunrise. Meanwhile, upstream dew points in light northwest low level flow are not much if any lower, so temperatures will not fall much lower than the upper 60s overnight. Will mention patchy fog in the HWO but will hold off on headlines. && .MESOSCALE UPDATE... Issued at 702 PM EDT Fri Aug 2 2024 H20 vapor imagery was vividly showing the upper low spinning over the Richmond, Indiana area early this evening. The low was interacting with deep moisture (anomalous PWATs to 1.75 inches) per Hi-Res soundings and strong instability with MLCAPES 1500 to 2000 J/kg to trigger isolated to scattered thunderstorms. These storms were rotating counter clockwise around the low per radar reflectivity mosaic. Look for the activity to continue at least for awhile after sunset, and then as instability dies and the low moves off to the east, so too will the storms by mid to late evening. && .SHORT TERM (This evening through Saturday)... Issued at 300 PM EDT Fri Aug 2 2024 Synopsis - Surface analysis late this morning shows low pressure over Southern Ontario, just north of Lake Erie. This was resulting in cyclonic flow across Central Indiana. High pressure was found over NB/KS. Water vapor imagery shows a deep upper low over Central Indiana. Skies were mostly cloudy across Central Indiana. Dew points across central Indiana remained very moist, in the upper 60s and lower 70s. Radar shows scattered showers and storms popping across Central Indiana and progressing southeast within the flow. Strong ridging and subsidence was found upstream over the northern plains and western Great Lakes. This afternoon and evening - Diurnal heating is expected to continue to fuel scattered showers and thunderstorms into the early evening. ACARS soundings continue to suggest favorable CAPE in place along with steep lapse rates as convective temperatures are reached through the late afternoon. Given the warm and humid air mass in place, a favorable set up remains for convection this afternoon. HRRR remains in agreement, suggesting scattered showers and storms across the area through 00Z- 02Z. Thus will continue to use high chance pops through 00Z-02Z, particularly across the eastern parts of the forecast area, due to proximity to the departing low. Overnight - The models suggest the upper low will push east of Central Indiana, allowing the ridging aloft over the western Great Lakes to begin to sag southward across Central Indiana. This will result in a subsidence and drying trend as seen within the forecast soundings. Any rain chances will be lost as forcing is lost with the departing low and lack of heating. Thus overnight skies are expected to show signs of decreasing cloudiness. As the previously mentioned surface high over the plains builds eastward, northerly lower level flow is expected. Only minor change in dew points are expected overnight as they fall to the mid 60s. Thus overnight lows in the lower to mid 60s will be expected. Patchy fog will be possible particularly in rural areas as dew point depressions fall to less than 1-2F. Saturday - Forecast soundings on Saturday trend toward a dry column through the day with attainable convective temperatures. Models suggest strong ridging building aloft which will lead to subsidence. This effect can be seen within the very dry forecast soundings within the middle and upper levels. Thus only partly cloudy skies will be expected due to a few CU clouds. 850MB temps will remain quite warm, around 15C. This will allow for highs on Saturday to reach the upper 80s to around 90. && .LONG TERM (Saturday night through Friday)... Issued at 302 PM EDT Fri Aug 2 2024 Saturday night through Monday... The rest of the weekend will continue the short term's trend to an overall less-active pattern as broad yet very weak surface high pressure crosses the Midwest. More reasonable precipitable water values closer to 1.25 inches and lack of forcing will promote widespread rain-free conditions. However, the subtropical ridge prevailing through the western two-thirds of the CONUS will extend its more zonal/eastern portions into the Midwest...which will maintain higher humidity with overnight lows between 65-70F. Slight moderation of daytime readings is expected as weak low pressure approaching to our north-northwest promotes light southwesterly breezes, with highs nudging upward from mainly upper 80s to lower 90s. Heat Index values may briefly exceed 100F Monday afternoon south of Interstate 70 under abundant sunshine, although Heat Advisory criteria is not expected to be reached at this time. Equally impactful may be areas of notable visibility reduction in pre-dawn fog over portions of the region that have recently seen heavy rains. Tuesday through Friday... The rest of the next work week will see a slow/modest trend to lower heights and back to near-normal late summer conditions...as broad troughiness that has been contained to central Canada shift southward to the far-north central CONUS. While this will not likely bring central Indiana the autumnal conditions expected for the Upper Midwest...following a second marginally hot day on Tuesday, widespread low 80s will hopefully be the rule for latter portions of the long term as the southern extent of amplified Canadian high pressure spills into the Midwest. While overall dry conditions are expected to continue, widely scattered showers/storms could accompany this transition...especially towards the southern Great Lakes where better forcing will follow the main cool frontal zone push. && .AVIATION (06Z TAF Issuance)... Issued at 1136 PM EDT Fri Aug 2 2024 Impacts: - Reduced visibility from fog early Saturday morning Discussion: Air mass change has been minimal and the lower troposphere is still moist. With light/calm winds and clear conditions, patchy/shallow fog, potentially locally dense is expected. This will diminish by around 1230-1300z. && .IND WATCHES/WARNINGS/ADVISORIES... None. && UPDATE...MK SHORT TERM...Puma LONG TERM...AGM AVIATION...BRB
