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 Northern Indiana wrote its last area forecast discussion before the first event at Jun 4, 1:35 PM EST, 40 minutes earlier.
Area Forecast Discussion National Weather Service Northern Indiana 235 PM EDT Sun Jun 4 2017 .SYNOPSIS... Issued at 235 PM EDT Sun Jun 4 2017 Scattered showers and storms will continue across northern Indiana and northwest Ohio through the evening. A few of these storms may produce damaging winds and heavy rain but any severe threat is expected to remain isolated. A few afternoon showers and storms are possible again tomorrow but no severe weather is anticipated. Highs tomorrow will still be around 80 but cooler and drier conditions are expected for the rest of the week. && .SHORT TERM...(This Evening through Tonight) Issued at 235 PM EDT Sun Jun 4 2017 As earlier feared, surface dewpoints struggling to climb out of the low/mid 60s, far from most raw guidance. This is likely due to deep mixing/high sun angle and limited agricultural evapotranspiration this early in the season. SPC/RAP mesoanalysis does show around 2000 J/kg SBCAPE to our SW, driven mainly by temps soaring near 90F. This has eroded weak cap in place and sporadic pulse convection is firing along old differential heating boundary. Convection is still struggling some though given lack of low level moisture. DCAPE is however climbing to around 1000 J/kg with steep low level lapse rates and RAP is insistent on better moisture pooling/instability later this afternoon. Still think an isolated strong/severe storm is possible during the late afternoon and early evening but coverage and intensity appear limited. Damaging wind gusts by far the only real threat but some brief heavy rain is also possible. Convection will continue to fester across our southern CWA through most of the evening/early overnight but expect any isolated severe threat to wind down around sunset. Entirely dry conditions not expected until early Monday morning. && .LONG TERM...(Monday through Sunday) Issued at 235 PM EDT Sun Jun 4 2017 Very little impactful weather to discuss in the long term period. Passing wave will merge with James Bay upper low and form a seasonably strong cutoff/closed low over the eastern Great Lakes through at least midweek. Trend over the past few model cycles has been a slightly more westward location of upper low, increasing the influence on our area's weather. A couple of vorticity spokes will rotate around the upper low and, combined with relatively cool temps aloft, may support a the chance for a few showers and storms. The first chance, driven mainly by residual low level moisture and diurnal heating, will arrive tomorrow. Some weak low level convergence along secondary cold front structure but overall forcing is weak and precip mainly supported by steep-ish lapse rates. Not steep enough to generate any substantial instability/strong updrafts but a few showers possible and isolated thunder can't be entirely ruled out. Best chances will be in the eastern CWA. Second chance for showers arrives Tue afternoon with loss of low level moisture being compensated for by better mid/upper level curvature. A few showers possible, mainly east of I-69, but thunder chances appear even lower and not worth adding a mention. No impact expected. Some non-zero chance for isolated sprinkles in our far E/SE Wed/Thur but upper low is pulling away by then with shortwave ridging and dry conditions expected. Next decent chance of rain not until Friday afternoon when next shortwave/cold front arrives. Cooler temps probably the main story. Predominate northerly flow and at least some cloud cover will keep highs on the cool side of climo. 850mb temps tank to around 5C in the core of the thermal trough late Tue/Wed. Expect highs around 70F during this time, slowly rebounding to upper 70s by the end of the week. Dewpoints on Tues and Wed will also likely drop back into the 40s, leading to a refreshing feel. && .AVIATION...(For the 18Z TAFS through 18Z Monday Afternoon) Issued at 138 PM EDT Sun Jun 4 2017 Remnant outflow boundary from earlier morning convection across the southern Great Lakes has provided focal point for scattered shower/thunderstorm development early this afternoon west/southwest of KFWA where sfc temperatures have warmed into the mid/upper 80s. Expecting these scattered showers/storms to overspread Fort Wayne terminal through 22Z. Given upstream trends , moderate amount of peak diurnal instability, and broad low level confluence did opt to include short duration tempo TSRA mention at KFWA in the 19Z-21Z timeframe and will assess trends whether an extension to this timeframe is needed over next hour or two for the late afternoon and/or early evening hours. Threat of rain/thunderstorms appears a bit more questionable at KSBN and have continue to omit with this TAF issuance. Thunder chances diminish at KFWA after 00Z tonight with dry weather through remainder of this period. Winds to shift northwest late tonight/early Monday morning behind a cool front with mainly VFR conditions through the period. && .IWX WATCHES/WARNINGS/ADVISORIES... IN...NONE. MI...NONE. OH...NONE.
