The episode as NWS IND wrote it up.
A front and an a low pressure system brought heavy rain to central Indiana for the second time in a week. Some areas received more than 2 inches of rain once again. This lead to road closures due to high water as well as new & prolonged flooding of area streams and rivers. Some water rescues were performed as well.

Area Forecast Discussion National Weather Service Indianapolis IN 1025 AM EDT Thu May 4 2017 .UPDATE... The AVIATION Section has been updated below. && .SYNOPSIS... Issued at 214 AM EDT Thu May 4 2017 In store today, another rainy day is. Low pressure over Arkansas will move into Kentucky. Spread rain across Central Indiana this will. Heavy, at times, rain may be. In effect for Central Indiana today a Flash FLood Watch is. A slow journey the low pressure system will make...across Kentucky Tonight and across Ohio on Friday. Bring more rain to Central Indiana through the end of the work week this will. In the region on Saturday broad low pressure will remain and more rain will be possible. Dry weather will return Sunday with colder temperatures as High pressure arrives. Then persist through the start of the next work week dry weather will. && .NEAR TERM /Today/... Issued at 948 AM EDT Thu May 4 2017 What a miserable day across central Indiana with persistent rain...raw northeast winds and temps primarily in the 40s to around 50 as of 1330Z. Little update needed as forecast has things well in hand. The axis of steadiest rainfall has aligned over the northern Wabash Valley and northwest half of the forecast area in the vicinity of a well noted deformation axis and on the poleward side of the 850mb thermal gradient. Further south across central Indiana...precipitation remains widespread but is starting to show some breaks in the activity. Likely to see this trend continue through midday as the nose of the low level jet which has been serving as a fuel source to the rainfall over the last 12 hours or so shifts slightly east. A renewed surge of moderate to heavy rain will lift north into the region during the afternoon with the arrival of deeper forcing aloft as the surface low centered in west Tennessee this morning approaches from the southwest. In addition...all hi-res guidance capturing the development of a trowal by late day into the region from the east. This should all but guarantee keeping the spigot on over the forecast area through the night. In a nutshell...100 pops continue through tonight. Lowered temps a few degree today based on current readings and expectation of little upward movement through the day. Previous discussion follows. Issued at 214 AM EDT Thu May 4 2017 Over Arkansas this morning surface analysis showed low pressure. In place across Central Indiana cool northeast surface flow was. An extensive shield of rain spreading across Central Indiana radar shows. To continued rainfall today many features point. Water vapor imagery shows a deep upper trough over the plains...heading east. Pouring into the Ohio valley, ahead of the trough deep moisture was seen. Forecast soundings today remain saturated. PWATs are less then the previous system...only around 1.25 inches. Deep moisture and excellent lift Time height sections show. Further support is seen from on the GFS 295k Isentropic surface...present is good up-glide with specific humidities over 8 g/kg. With NE winds at the surface and southerly winds aloft a classic overrunning situation in place is. No adjustment needed to the ongoing flash flood watch and 100 pops. A lack of instability and CAPE forecast soundings reveal. Inhibit thunder development this will, and less likely heavy downpours will be. Reasonable it looks for slow and steady moderate rain. Will continue to trend highs today cooler than the blend given the expected clouds...rain and cool northeast flow. && .SHORT TERM /Tonight through Saturday Night/... Issued at 214 AM EDT Thu May 4 2017 Change little through Friday the weather will. Through Friday...The GFS shows the deep upper low...nearly cut- off...pushing through the Tennessee valley. In place across southern Indiana a slow moving surface low this keeps. Amid weak to moderate forcing...This will result in Wrap around moisture and cyclonic flow across Central Indiana through Friday. Again...this should result in a longer duration...slow and steady light rains. Not Likely convection does appear as Forecast soundings continue to show minimal instability. Still given all the upper support and plentiful moisture...confidence for rain is high. Reasonable the models seem suggesting several inches of rain across the area through the period. Toward categorical will trend pops and trend highs cooler than the blend and lows warmer. A brief break looks in store on Friday Night as the upper low finally moves east to West Virgina. quickly northeast the surface low does move toward Western New York. Move east of the area the best moisture does on Friday night. Drying within the column forecast soundings show. Toward a low chance pop only will trend on Friday Night. Depart quietly though this system will not. Another short wave the GFS and NAM again suggest diving quickly south across the Great lakes to Indiana. Shallow m4oisture with some instability Forecast soundings show here...particularly in the morning. Easily reached convective temperatures in the lower 50s will be. Thus Chance pops on Saturday will be needed as the upper support arrives along with cooler air aloft in the afternoon hours. By Saturday night forecast soundings go dry as upper support and any heating is lost. To New England the upper low departs on Saturday night. Trend toward dry and cold then with NW flow expected the forecast will. && .LONG TERM /Sunday Through Wednesday/... Issued at 255 AM EDT Thu May 4 2017 Ensembles indicate a fairly static upper pattern during this period, with deep troughs over the western states and off the East Coast, and ridging over the Plains and Midwest. Some of the ensembles are indicating the potential for a disturbance to drop southeast through the area towards the middle of next week around the Plains ridge. The members that are showing this disturbance are quite aggressive with precipitation potential, especially by next Wednesday. Will continue with a dry forecast for Sunday and Monday, and will add some PoPs for next Tuesday and Wednesday based on above. && .AVIATION /Discussion for the 041500Z TAF Update/... Issued at 1025 AM EDT Thu May 4 2017 Only minor adjustments needed for the morning update as ceilings have slipped to near IFR levels at all terminals. Added in gusts for the afternoon based on current obs. 12Z discussion follows. Ceilings have yet to lower much, except in the KLAF area, as low level dry air from the east advects into the area. Large scale convergence and precipitation should allow for ceilings to fall as the morning progresses, reaching the IFR category by midday or early afternoon. Rain expected to continue throughout the day. There is some threat for a few embedded lightning strikes midday and on into the afternoon hours over the southern terminals, as some weak elevated instability may work into southern Indiana. Surface winds 040-070 degrees this morning will gradually back around to 010-030 degrees by early evening. Surface gusts 20-24 kts possible at times, especially in the KLAF area. && .IND WATCHES/WARNINGS/ADVISORIES...

4 flood. Local standard time, as filed.
Minor street and yard flooding observed in and near this location. This report was obtained via Twitter.
Rainfall of 2.55 inches was observed in the area, along with numerous flooded roads.
A trained spotter reported flooding over several roads in northern Monroe County due to thunderstorm heavy rainfall.
Also, WISH-TV reported that the Monroe County dive team responded to two separate calls related to flooded roads. The first call was at Anderson and Bean Blossom Roads at 7:30 AM when they responded to a call of a vehicle mostly submerged in flood water. The driver, a 53-year-old woman, was out of the vehicle and safe by the time they arrived. Dive team members observed a second car driving into flood waters after clearing the first scene. They proceeded to push the two occupants to more shallow waters before placing them in a squad car for safety.
Additionally, the Bartholomew County Sheriff’s Office says its water rescue team pulled a woman from an overturned, submerged car at about 1:30 AM Saturday south of Columbus. It says she was transported to a hospital with minor injuries. No details on location or why the car overturned.
Indiana Department of Homeland Security reported seven people and a dog being rescued from where they were camping behind the city's waste water treatment plant. They became stranded by rising water near the 800 block of South River Road. Police received a call from one of the campers at about 7:45 AM EDT Saturday. Conservation officers had to launch an air boat through a field to get to them. No injuries were reported.
