Storms Rumble In During The Overnight…
Central Indiana was blessed with a very pleasant start to the work week (despite that frosty open to the day), with plentiful sunshine and highs in the lower to middle 60s. Unfortunately, the pleasant weather won’t hold, as changes are in the offing as early as the overnight period. We’ll enter a rather challenging northwest flow regime over the next couple of days and periods of showers and thunderstorms will ride in a northwest to southeast fashion from time to time.
We believe greatest coverage of thunderstorms will ride into north-central Indiana during the overnight period, and bracket an arrival between midnight and 1a, with heavier rain and embedded thunderstorms increasing in overall coverage from 3a-4a.
Here are a couple images of what the radar may look like overnight: 1a and 4a.
Showers and thunderstorms will continue to impact the central portion of the state through the rush hour before storms diminish and give way to dry time early Tuesday afternoon.
Another batch of showers and thunderstorms may fire during the prime heating hours Tuesday evening and impact areas from mainly Indianapolis and points south.
Unsettled weather will continue as we push through midweek, including another round of showers and thunderstorms late Wednesday into Thursday (likely following a similar path to what tonight’s storms take).
While we’re confident on the overall setup, details with regard to timing and rainfall amounts are much less certain in this fast-moving northwest flow aloft. There will likely be some neighborhoods that receive between 1″-2″ of rain between Tuesday morning and Thursday morning, while other neighborhoods receive an 1″, or less. It would appear heaviest rainfall totals will paint themselves in a thin line from northwest Indiana, through central Indiana, including Indianapolis, and on into far southeastern portions of the state.

Rain And Storm Chances Return…
Highlights:
- Frosty start
- Rain chances return
- Dry and pleasant close to the week
Wet Weather Returns…Bright and sunny conditions are in place as we open up a new work week, and many are awaking to frost out the door this morning, as well. Light winds, dry air, and clear skies allowed temperatures to plummet into the lower and middle 30s for many central and northeast IN neighborhoods overnight.
Clouds will increase later today and showers will arrive tonight. We’ll introduce thunderstorms into the mix Tuesday as a frontal boundary begins to settle south. That frontal boundary will begin to stall near the region midweek and additional waves of showers and thunderstorms will impact the region (especially the southern half of the state) through Thursday.
Drier weather will return to close the week and we expect a very pleasant start to the weekend.
A new weather maker will deliver a shower chance Sunday.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 1.00″ – 1.50″

Frosty Mornings; Heavy Rain Returns Next Week…
Highlights:
- Needed dry time
- Frosty mornings
- Heavy rain and storms return
Drier, But Unseasonably Cool…Much-needed dry time has arrived. High pressure will dominate our weather pattern this afternoon through Monday, supplying dry skies. Despite the return of the sunshine, temperatures will continue to run much cooler than average. In fact, with drier conditions in place, overnight lows will tumble into the frosty range Sunday and Monday mornings. Cover up that tender vegetation.
Our next weather maker will arrive on the scene by the middle of next week as a frontal boundary stalls out over the region. Unfortunately, this is a rather ominous signal for heavy rains to return. We forecast periods of showers and thunderstorms Tuesday through Thursday before wrapping up the work week with scattered showers. We’ll keep a close eye on the data over the next few days as additional heavy rains are the last thing we need.
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 1.50″ – 2.00″

More Heavy Rain Today, But Improving Conditions As We Move Into The Weekend…
After a relative “lull” in the rainfall coverage and intensity overnight, rain is expanding in coverage and intensity yet again this morning. While there will be a rather sharp cut-off to the west, additional heavy rains are ahead from northwestern Indianapolis ‘burbs (including places such as Brownsburg, Whitestown, and Sheridan), Indianapolis, and points south and east.
HRRR simulated radar shows this rain shield nicely as we progress through mid and late morning.
Additional rainfall of 1″-1.5″ is likely from Indianapolis and points south and east with this band of rain before drier weather finally works in here this afternoon and evening. Otherwise, expect continued windy, cold, and raw conditions today as temperatures remain in the 40s this afternoon, including wind chills in the 30s.
Looking ahead, one last batch of rain will arrive on the scene Saturday morning.
We’ll finally get rid of the rain and introduce a drier regime Saturday afternoon into Sunday, including a sunny close to the weekend. With the drier air, overnight lows will fall to frosty levels Sunday and Monday mornings (lower to middle 30s).
More on the longer range this weekend!

Heavy Rain And Flooding Update…
Unfortunately, we don’t have any changes to our ongoing forecast. Widespread rain will continue through Friday, occasionally heavy. By the time all is said and done, many local rain gauges will check in between 3″-4″. Lets break it down:
This morning’s radar shows rain intensifying across central and western portions of the state this morning, especially west of I-65.
7:30a radar snap shot.
Plan on steady rains to continue today, periodically heavy. If you live near a body of water, remain aware of current water levels. Significant rises will begin to take place this afternoon as the periodically heavy rains add up.
12p forecast radar.
Widespread rain will continue overnight into Friday morning. As low pressure slowly tracks northeast, we think a “deformation zone” will set-up shop across central Indiana Friday. Within this large band of rain, multiple intense rain bands will pivot through central Indiana. Flood concerns will remain high through Friday.
We should finally get into drier air Friday night before one last round of showers pushes southeast across the state Saturday morning. As of this update, we bracket the 4a-10a timeframe for renewed wet weather. By Saturday afternoon, drier air should win out and result in a much more favorable forecast Saturday night into Sunday.
By the time all is said and done, widespread 3″-4″ storm totals are expected, and will most certainly lead to flooding. Even localized 4″+ amounts can be expected within areas where the heaviest rain bands persist.
In closing, as drier air begins to arrive on the scene Saturday evening, much cooler conditions will result in areas of frost into early next week. Lows in the lower to middle 30s will be common Sunday and Monday mornings across central Indiana.

Flooding Concerns Return…
Highlights:
- Heavy rain returns
- Unseasonably cool
- Drier weather returns late in the weekend
Live Near A Body Of Water? Keep An Eye On The Level…Central Indiana will deal with an extended period of rain, occasionally heavy, tonight through Friday afternoon. With saturated soils in place, an additional widespread 2.5″-3.5″ (with locally heavier amounts) between now and Saturday morning, flooding concerns are very high. As the lead off states, please remain aware of water levels if you live near a creek, stream, or river. The other aspect of this storm will be unseasonably chilly air and gusty easterly winds that will shift to the north Friday night into Saturday.
The weekend will provide a drier trend, but the improvements will be slow to occur. Showers remain in our Saturday forecast before drier air finally wins out Sunday with sunshine. The worry once to Sunday and Monday mornings will be the potential of frost and freeze conditions- especially in communities away from downtown. Remember, no planting around these parts until after Mother’s Day! 😉
Shower chances return by the middle of next week!
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 3″ – 4″

Unseasonably Chilly; Another Heavy Rain Maker Blows Into Town…
Clouds will lower and thicken Wednesday morning and give way to an expanding rain shield late morning into the early afternoon hours. Initially this rain won’t be heavy, but will begin to increase in overall coverage and intensity as we progress into the nighttime hours.
Forecast radar around lunchtime shows rain increasing across central IN.
Rain becomes heavy Wednesday night.
The culprit behind this new heavy rain maker is a deepening surface low pressure system that will slowly track from Arkansas (Wednesday night) northeast along the Ohio River (Thursday) and into Ohio (Friday). Not only will this spread heavy rain across central Indiana, but will also result in strong and gusty easterly winds Thursday into Friday, and unseasonably cold air. In fact, temperatures Friday will likely remain in the 40s across central IN with wind chills in the 30s. Add in that wind-driven rain and we have the makings for an UGLY day.
Periods of heavy rain will fall on the region Wednesday night into Friday and by the time all is said and done (Saturday night) widespread rainfall of 3″ is likely across most of central Indiana. Locally heavier totals will be possible where the most persistent heavy rain bands set-up shop.
We’ll begin to dry things out Saturday night into Sunday, but unseasonably chilly air will remain. Lows over the weekend into early next week will grow cold enough to allow patchy frost to develop in outlying communities. We think low to mid 30s will be common across the region Sunday and Monday mornings.

Another Big Rain Maker; Unseasonably Chilly…
Highlights:
- Limited sunshine
- Another big rain event awaits
- Prolonged period of chilly weather
Jackets And Rain Gear Needed…Without question, Tuesday appears to be the “pick of the week” across central Indiana as we get into some briefly drier air. Enjoy it, as a new storm system will deliver heavy, wind-driven rain and unseasonably chilly air as we progress through mid and late week.
Clouds will lower and thicken Wednesday morning and give way to an expanding shield of rain as morning wears into afternoon and evening. As the surface low tracks closer to the region, an increasingly strong and gusty easterly wind will develop and combine with the chilly rain to lead to a truly “raw” period of weather to close the work week. It’ll feel more like early-March than early-May around these parts. Unfortunately, it still appears as if this next storm will deliver hefty rainfall totals on our already water-logged landscape. Data paints a widespread swath of 2″-3″ totals with locally heavier amounts. Flooding, once again, appears likely and if you live near a body of water, it’ll be important to keep a close eye on water levels Thursday into the weekend.
Widespread rain Friday should slowly give way to improving weather conditions over the weekend: scattered showers Saturday and dry, cool weather Sunday. Speaking of cool, temperatures will continue to run well below average, and lows Saturday through Monday mornings’ may result in patchy frost in outlying areas…
Upcoming 7-Day Precipitation Forecast:
- Snowfall: 0.00″
- Rainfall: 2.50″ – 3.50″
