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.

An unseasonably mild week is on tap with a couple chances of rain and embedded thunder. Widespread, organized severe weather isn’t anticipated in the upcoming week.
Forecast Period: 03.02.24 – 03.09.24
After a quiet weekend (including a progressively brighter sky :-)), unsettled weather will come at us in 2 waves in the week ahead: Monday evening into Tuesday morning and again Friday evening into Saturday. In both cases, we expect widespread precipitation. In the case of our early week system, embedded thunder (non-severe) can’t be ruled out. With our late week storm system, the early call now is for more of an organized general rain to fall. Colder air will return to the region by the latter part of next weekend, potentially including some snow showers by Sunday.
Upcoming Storm Dates to keep an eye on:
*10-Day Rainfall Projection: 1.00” to 2.00”

Tomorrow we’ll welcome in meteorological spring and the first couple weeks of March appear to continue the unseasonably warm trend. At times, additional warm records will likely fall.
This is strongly correlated with the Madden-Julian Oscillation highly amplified in the classic warm phases this time of year. (You can absolutely say goodbye to any sort of sustained cold prospects this time of year with the MJO in phases 4, 5, and especially 6). Now, down the road, we’ll want to watch and see if we can maintain this amplitude and rumble into the transitional colder Phase 7 before a potential opportunity to see cold grow more impressive should we *finally get into Phase 8 late month. Remember that we made an attempt at that back in mid-February before things instead collapsed into the neutral phase. Moral of the story for folks longing for one more bout of sustained cold prior to the warmer months ahead, “don’t hold your breath.” The trend certainly isn’t your friend.
Back to the present. No matter what the teleconnections say, an amplified MJO will always win out. And the current MJO forecast to roll through the phases listed above screams that our recent warm times will “keep on keepin’ on” as we navigate the 1st half of March.
The Phase 5 and Phase 6 composite analogs at 500mb (upper air pattern) for an El Niño March:
What this should also result in is an active first half of the month, including above normal rainfall and likely at least another early season strong to severe weather event before we get to mid month.
It’s a classic pattern that should feature low pressure systems ejecting out of the Southwest and South-central into the Plains and western Great Lakes region. That puts our neck of the woods on the warm/ wet (and at times stormy) side of the equation.
As we move into late-March and early April, we’ll have our eyes focused on the MJO and whether or not we can, indeed, get into those traditionally colder phases. Stay tuned.
