Weekly #AGwx And #Severe Weather Outlook…

Updated 03.10.24 @ 8:21a

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.

Upcoming Storm Dates to keep an eye on:

  • 03.13
  • 03.14 – 03.15
  • 03.16 – 03.17

*10-Day Rainfall projection: 0.75” – 1.50”

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.

Storms Become More Widespread Through The Morning; Another Storm System Arrives Late Week. Still No Sign Of A Flip To Colder…

Updated 03.05.24 @ 7:53a

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.

Sunday Morning Rambles: Tracking 2 Systems This Week And More Unseasonably Warm Conditions Ahead…

Updated 03.03.24 @ 8:19a

A gorgeous Sunday is on deck with highs rising into the 60s and near 70° west. Enjoy that sunshine while we’ve got it!

Dry conditions should prevail through the daytime hours Monday before showers and embedded thunder roll into town overnight and Tuesday morning. Unsettled conditions will hold through the day Tuesday.

Rainfall totals of 0.25” to 0.75” will be common by Tuesday night across the region.

The next low pressure system and associated frontal boundary will impact us Friday into Saturday. Look for a more widespread, heavier round of precipitation with this particular system as we close the work week.

Despite cooler shots of air flowing in briefly behind frontal passages, there’s no sustained below normal temperature regime on the horizon, and for good reason with this kind of MJO:
