Stormy Pattern Returns; Localized Flash Flood Threat Emerges…
A cold front will sink south into the Ohio Valley Tuesday afternoon before stalling out through the remainder of the work week and into the weekend.
Unsettled weather returns as a frontal boundary stalls out across the region into the upcoming weekend.
Rain and storm chances will increase in overall coverage and intensity as we move into Tuesday- particularly during the afternoon hours. With precipitable water values exceeding 2″ at times, locally heavy downpours can be expected.
Despite cooler (still mighty humid) temperatures arriving, the overall pattern won’t change significantly into late week and this weekend. With the frontal boundary draped across the Ohio Valley, periods of showers and thunderstorms will remain in the forecast. At times, disturbances will track along the boundary and lead to increased coverage of storms. Perhaps Thursday and Friday will serve up the greatest coverage of thunderstorms as a surface wave moves out of the central Plains into the Great Lakes.
The combination of a juicy air mass and a stationary boundary draped overhead spells a flash flood risk. The lack of any sort of overall steering current suggests the potential of thunderstorms that may train over the same communities at times. As mentioned earlier, precipitable water values (PWATS) will approach and exceed 2″ and this will support torrential downpours at times.
Officially, we think the upcoming 7-day period will deal out widespread 2″ to 3″ rainfall totals across central Indiana, but there will be locally heavier amounts where thunderstorms train.
After a dry few days with exceptional heat, the unsettled and cooler pattern, overall, will be welcomed with open arms!

And Then The Rains Came…
Central Indiana has dealt with heavy rain over the past (24) hours, and it’s continuing this morning. In some areas, rainfall has been excessive. Note the latest Storm Total Rainfall map below. Areas of light green indicate where 1″ of rain has fallen (since June 8th), yellow indicates where 2″ of rain has accumulated, and the orange hues represent areas of 4″ to as much as 5″ in spots. – Again this is just rainfall from Friday morning through 7a Monday.
Moisture continues to stream across central and southern Indiana this morning, and some of this rain is falling at a moderate to heavy rate.
Widespread rain will eventually come to an end later this afternoon before scattered showers and thunderstorms redevelop this evening into tonight. Potential is also present for the possibility of another thunderstorm complex impacting parts of the region late tonight into early Tuesday- especially across the southwest part of the state. Scattered thunderstorm chances will remain Tuesday (more of the splash and dash variety as opposed to a widespread soaker).
Eventually, drier air will work into the state for midweek and rainfall coverage will diminish Wednesday and most of Thursday.
An increasingly moist air mass will return to close the week and with the increasing humidity, rain and storm chances will make a return Friday into the upcoming weekend.

Records? We’ve Got Records, And Looking Ahead…
Meteorological spring began March 1st (though you wouldn’t know it with all of the cold and snow lately). Snow dominated the headlines in March with nearly a foot that fell. Cold also was a story as temperatures ran significantly below normal. Check out these impressive stats, courtesy of the Indianapolis National Weather Service:
- The 10.2″ of snow that fell at Indianapolis on the 24th set the daily snowfall record and 2nd snowiest March day ever.
- The 11.6″ of snow at Indianapolis resulted in March 2018 going down as the 6th snowiest March on record.
- Temperatures ran 3.3° below average.
Though we’re only a few days into the month of April, the fourth month of the year is already trying to “out do” March. Sleep has been few and far between here in the good ole forecast office with such an active start to the month. From the heaviest Easter snow on record to setting the wettest day in April ever and widespread flooding, we’ve had it all in just the first (3) days!
- Indianapolis recorded 3.9″ of rain on the 3rd- good for the daily rainfall record and greatest amount of rain within any April day on record.
- Easter snow: though some places received more (3.2″ at Whitestown and up to 6″ of snow at Lafayette and Frankfort), Indianapolis accumulated 2.1″ which set a record for snowiest Easter and snowiest April 1st.
At one time what looked like another snow-starved snow season is now getting oh so much closer to “average,” with the late season rally. As the saying goes, “it’s never over until it’s over!” In Whitestown, we’re now over 30″ on the season! Indianapolis is up to 22.7″ on the season and only 3″ below average.
Looking ahead, the upcoming couple weeks should continue to promote an active pattern. Temperatures should follow the colder than normal theme and precipitation should run above average. For the snow, we’re not done with that yet, either! Speaking of snow, we’re tracking additional opportunities for snowfall this weekend and again early next week… Hang in there, spring will get here eventually…
More of a winter than spring feel this week. Image courtesy of Weatherbell.com.
Colder than average temperatures continue in the 6-10 day.
Additional opportunities of accumulating snow are present over the next couple weeks.
An active pattern remains…
