$$What forecasters said that day
The local office's own words before this river flood warning went out, 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 this river flood warning went out at Jul 22, 6:49 AM EDT, 1 hour 25 minutes earlier.
Area forecast discussion, Jul 22, 6:49 AM EDT, 1 hour 25 minutes before
Area Forecast Discussion National Weather Service Indianapolis IN 649 AM EDT Sat Jul 22 2017 .UPDATE... The Aviation section has been updated below. && .SYNOPSIS... Issued at 338 AM EDT Sat Jul 22 2017 Central Indiana will remain on the edge of a strong upper ridge through tonight....maintaining hot and exceptionally humid conditions. Chances for thunderstorms will continue until a frontal boundary can push through the area overnight into early Sunday. A secondary front may bring additional scattered storms on Sunday evening before high pressure builds in with mainly dry weather and seasonable temperatures for the early part of the week. && .NEAR TERM /Today/... Issued at 338 AM EDT Sat Jul 22 2017 Active early morning continues across northern portions of central Indiana as a bowing convective line moves into the northern Wabash Valley. Yet another steamy overnight across the region as 07Z temperatures were largely in the mid and upper 70s. Convection and heat remain the primary concerns for today once again as the region resides on the periphery of the heat ridge. The first order of business will focus on the potential for severe convection prior to daybreak with expectations of additional robust storm development by late day over northern counties near the sagging frontal boundary. Bowing feature progressing southeast across northern portions of the forecast area at 0630-07Z. LAPS sounding at KLAF indicates the presence of an inversion below 850mb which may be inhibiting the strong winds being sampled via KIND radar from being fully realized at the surface. The convection should continue tracking southeast along the instability axis and theta-e ridge which extends through Indy and toward the Cincy metro. Damaging wind gusts remain the primary threat with these storms early this morning...along with torrential rainfall and despite the quick movement to the storms...localized flooding as well. Severe Thunderstorm Watch #431 remains in effect through 11Z for the northeast half of central Indiana to account for the current storms. Expect the convection will be moving on into western Ohio near daybreak in a weakening state. The southern flank of the convection back across northern Illinois may move across the same areas later this morning before diminishing and will need to monitor. The general trend though as we go through the morning and into the early afternoon will be towards brightening skies...clouds scattering and the focus shifting back to the heat and humidity. With moisture pooling and a surge of heating ahead of the approaching frontal boundary...potential is there for dewpoints to hang in the mid and upper 70s into the afternoon as temps surge into the 90s. This will promote a strongly unstable airmass by late afternoon with MLCAPEs nearing 4000 J/KG being realized immediately ahead of the front over northern counties. With a low level jet likely to energize over the region by late day and a remnant outflow boundary from the morning convection setting up over northern portions of the forecast area...expect convection to erupt quickly after 21Z and grow upscale rapidly into the evening aided by cooling aloft. Damaging winds will be the primary severe weather threat but all forms of severe weather will be possible. Precip water values above 2 inches will support a continuing heavy rain and flooding threat as well. Temps...as mentioned above...heat and humidity will again be factors today. Expect highs ranging from the upper 80s over northeast counties where convective impacts lend towards more uncertainty on temps to mid 90s in the lower Wabash Valley. Max heat indices again will get above 100 degrees in most areas with the highest values over southwest counties. The heat advisory will continue in its current state and location until 23Z. && .SHORT TERM /Tonight through Monday Night/... Issued at 338 AM EDT Sat Jul 22 2017 Forecast challenges focus on precip chances...especially tonight and again late Sunday and Sunday evening. Convection will likely be ongoing this evening as development takes place over northern counties and progresses southeast through the evening and overnight ahead of the cold front. A surface wave along the boundary...continued influence of a low level jet...BL shear values around 30kts and a strongly unstable airmass all support a threat for severe storms this evening gradually transitioning into more of a heavy rain threat overnight. Highest pops will be employed over the eastern half of the area where parameters will be just a bit more favorable for more widespread convection. Precip water values will remain above 2 inches and combined with freezing levels near 15kft supporting warm rain processes...torrential rainfall and flooding will continue to be concerns as the storms surge south overnight. Growing confidence that most if not all of the convection will be out of the forecast area by 12Z Sunday with the front settling south of the Ohio River. Much of the day Sunday should be dry with an edge being taken off the humidity levels. A secondary front associated with a sharp upper wave diving out of the western Great Lakes may serve as a focal point for renewed convective development to the northwest of the region Sunday afternoon...possibly spreading into the northern half of the forecast area during the evening. Steep mid level lapse rates in response to cooling aloft suggestive that strongest storms may carry a damaging wind and large hail threat. Will bring low chance pops back into the northern counties Sunday evening as a result. Convection will diminish overnight Sunday with high pressure building south into the region on Monday with cooler and noticeably less humid air. Likely to see diurnal cu develop on Monday before skies become mostly clear Monday night. Temps...it will remain very warm on Sunday with low level thermals supporting highs from the mid 80s to around 90. Temps will fall back into the lower and middle 80s Monday with cooler air aloft advecting into the region. Lows will slide back into the 60s through the period. && .LONG TERM /Tuesday through Friday/... Issued at 338 AM EDT Sat Jul 22 2017 High pressure will maintain the dry and pleasant airmass across central Indiana and the Ohio Valley through midweek before a more active pattern returns as a cold front drops through the area late week. The upper ridge that will be squashed back to the southwest by Monday will begin a reexpansion back towards the area by the middle of next week with southerly flow reestablishing. This will lead to a progressively warm and more humid airmass back into the forecast area by Wednesday as highs rise into the upper 80s to near 90 over much of the region. A cold front will track slowly south into the area by Thursday...forcing the core of the ridge to retrograde back into the southern Plains as mid level heights buckle once again. The best chance for convective impacts over central Indiana will exist on Thursday and Thursday night as the frontal boundary is draped across the Ohio Valley. The boundary should shift south of the region by Friday with rain chances diminishing as weak high pressure expands in from the north. && .AVIATION /Discussion for the 22/12Z TAFs/... Issued at 646 AM EDT Sat Jul 22 2017 Predominantly VFR through the period outside of convection. Convection will be a threat early in the period at LAF and later this afternoon into the evening at the other sites. Uncertainty precludes more than a VCTS mention at this time. Winds throughout the period will be 10KT or less, predominantly out of the southwest, becoming west and northwesterly late in the period. && .IND WATCHES/WARNINGS/ADVISORIES...
