After a couple predawn showers Wednesday, the remainder of the day should be quiet and free of any significant rain. However, by this time, eyes will be focused on the possibility of a more significant event on Thursday.
Model guidance is beginning to suggest this will come at the state in (2) waves. The first rain/ storm cluster will likely arrive mid to late Thursday morning and may feature some embedded strong/ severe cells across downstate Indiana. Given the ingredients in play, hail would be the greatest threat from these morning storms across southern Indiana. Further north, across immediate central Indiana, severe weather isn’t expected, but general rain and storms will be a good bet, including locally heavy rain.
11a Thursday forecast radar
We will then likely see a lull in the activity into the early to mid afternoon hours before a second round of storms blows through during the evening. This 2nd wave of storms may feature more of a damaging wind threat from places in and around Bloomington and points south. From this distance, it appears as if the time period between 5p-8p is the one to watch.
6p Thursday forecast radar
While it continues to look like the more substantial severe threat will be south of the region, that isn’t to say the southern portions of the state won’t see a warning or two Thursday and we’ll continue to keep a close eye out as time draws closer.

Above to well above normal temperatures will dominate the upcoming 7-days across the eastern half of the country. Meanwhile, cold will rule across the Rockies and points west.
The Gulf will open for business this week. 2 systems will tap into that Gulf of Mexico moisture, resulting in well above normal rainfall into the Midwest, Great Lakes, and Ohio Valley.
Widespread rainfall amounts of 1.50″ to 2″ can be expected across central IN in the week ahead, with locally heavier totals.
While the SPC doesn’t currently have any organized severe weather risk outlined in their Days 3-7 outlook, we’ll want to keep an eye on Thursday across the MS Valley into perhaps the OHV for a severe threat.
Forecast period: 03.21.21 through 03.28.21
While the period will open on a quiet note, we’re tracking 2 storm systems of significance in the week ahead. The first system will produce a smattering of showers and storms Tuesday before a second (stronger) storm system lifts northeast into the region Thursday. This is the system that will require attention as time draws closer. If the European’s further northwest track comes to fruition, enough warmth and humidity will be pulled north to result in at least a threat of stronger storms into our region. Regardless, heavy rain is a good bet Thursday as this storm blows through. The period will end with quieter weather as we get set to head into next weekend.
