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).
An upper level ridge will dominate in the week ahead, but note the building heights late in the period across western NA. That will help promote a different (colder) airmass here over the wknd into early next week.Warmer than average temperatures can be expected this week from the Plains and points east.Precipitation should check in right around average this week across central IN and the Ohio Valley as a whole.
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.
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…
