Wednesday Morning Rambles: Talking Storms And A Cooler Pattern To Close Out March…

Updated 03.13.24 @ 5:44a

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.

Long Range Report: Period Opens With More Of The Same, But Cooler Than Normal For A Change Late Month…

Updated 03.09.24 8:14a

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.
