Most of today will be dry and unseasonably mild. We’ll watch radar trends this evening to see if storms are able to ignite, at least in widely scattered fashion. If this does, indeed, take place it would most likely be after sunset.
A better chance of more widespread showers and thunderstorms awaits Thursday, likely in a couple of different waves between the afternoon and evening hours.
The Storm Prediction Center (SPC) highlights far western portions of the state in a Slight risk of severe weather (damaging straight line winds are the biggest concern) Thursday. We’ll watch today’s trends to see if this needs expanded further east for potential severe impacts Thursday.
We’ll transition to a general rain Friday morning before a drier theme arrives for the 1st half of the weekend. By that point, rainfall totals should check-in between 0.50” and 1” for most.
Saturday actually isn’t looking bad with the opportunity of sun and pleasant temperatures ahead of a colder push of air Sunday night. Speaking of that, temperatures should grow cold enough to allow snow to fly across the region by Monday morning. Despite the recent stretch of unseasonably warm temperatures, we can’t rule out heavier snow bursts creating a quick coating to dusting of wet snow on grassy surfaces.
Ah, storms to snow- March at its finest in the Hoosier state.
As we look ahead to the remainder of March, the pattern appears to be in position to lead to a colder than normal regime for a change. It should be noted that we don’t see any significant cold during the late month time frame, rather a setup that should drive a slightly cooler than normal pattern (overall) over the last 10 days, or so of the month.
More on how we think April opens later this week in our long range report.

Another unseasonably mild week awaits, but one thing is becoming increasingly clear: we’re not finished with the cold yet. The transition to a colder time of things next week will come with unsettled conditions late this week and the weekend (I know, timing isn’t on our side).
Forecast Period: 03.10.24 – 03.17.24
The period will open with dry and seasonably chilly conditions before a southwesterly flow takes hold and helps promote yet another quick warm-up in the work week ahead. A weak and fast moving system may deliver some scattered showers midweek but the lions share of our moisture this week will come Thursday and Friday. Colder air then pours in here over the weekend with the potential of snow getting involved by this time next week.
Upcoming Storm Dates to keep an eye on:
*10-Day Rainfall projection: 0.75” – 1.50”

It’s been a very warm March. So far, Indianapolis is running nearly 13° above the average month-to-date.
In the short-term (Week 1), the pattern will remain on the milder side of normal.
That all begins to change as we move into Week 2.
This is largely driven by the MJO sprinting through the traditionally warm phases for this time of year into the colder Phase 8 late month.
The temperature composite analog for MJO Phase 8 in March during an El Nino season:
Strikingly similar to what we see above on the Week 2 charts, huh?
The teleconnection suite aligns towards a cold look by Week 2.
A potentially more significant storm system looms late next week or over St. Patrick’s Day weekend to usher in the pattern change. Otherwise, with a colder pattern than normal settling in Week 2, this will also likely lead to a drier airmass and subsequent opportunity to dry out after a wetter than normal open to March (also of note is that we’re running a little more than 1″ above normal, year-to-date).
No way to be specific with details from this distance, but given the look to the overall pattern, I’d be surprised if we end the month without an opportunity of a little wet snow with the colder transition.

Updated 03.08.24 @ 7:50a “Showery” weather through the early to mid afternoon will give way to an increasingly heavier rain by evening, continuing through the overnight. This is all thanks…

We’ve had a few storms north of the city, itself, early this morning, but for the bulk of the I-70 corridor, things are just now starting to get “busy.” Anticipate rain and storm coverage to continue to expand and grow heavier through the late morning into early afternoon before diminishing.
Rainfall totals of 0.25” to 0.75” will be most common with a few localized 1”+ reports. Rain and storm coverage will diminish through the afternoon and evening hours across the region.
High pressure will briefly build into the region midweek, allowing for drying skies and pleasant early-March conditions. Enjoy, as another storm system will deliver a round of rain and embedded thunder Friday PM and Saturday.
We turn briefly colder Sunday (and windy) but by Monday, the next warm-up is already scheduled to be well underway. This is just another instance of a brief chilly blast without any legs.
Speaking of cold, while there does remain a window of opportunity for a below normal regime to develop very late March and early April (if we can finally get the MJO to slide over into the colder phases), the short to medium term is still void of any sort of chill, at least for more than a day or 2 behind passing storms. Note the Week 2 ensemble data is still much warmer than normal for our neck of the woods. – A direct byproduct of the MJO rumbling through those classic warm phases.
