Friday Morning Rambles: Blast Of Arctic Air; Halloween Night Snow And More On November…
Updated 10.27.23 @ 7:09a
I. Most of our Friday will be rain-free and unseasonably pleasant. Enjoy as time is ticking. A cold front arrives tonight with increasing shower and thunderstorm chances after dark, continuing through the overnight. Most area rain gauges will accumulate 0.10” to 0.25” with this initial wave of rain, but there will be a few lucky folks that pick up 0.50” +.
II. A second, more widespread, round of rain will push across central Indiana Saturday night and Sunday morning followed by a potential break through most of the daytime Sunday. One final round of rain will then arrive Sunday night into the predawn hours Monday. Look for nearly steady or slowly falling temperatures into the upper 40s Sunday and highs remaining stuck in the 40s area wide Monday.
III. As attention shifts to Halloween, itself, a vigorous piece of upper level energy will dive into the Ohio Valley. Originating in Alberta, this will officially be the season’s first Alberta Clipper.
This feature will offer up a round of gusty winds and snow showers Halloween night into the predawn hours Wednesday.
We’ll wake up to temperatures in the 20s and ‘chills in the 10s Wednesday morning.
IV. We’ll dive in to our November pattern in greater detail with a video this weekend, but as of now, the early call is for a fairly typical November with many “ups and downs” and an overall transitional regime through the bulk of the month. Again, more on this and the associated pattern drivers a bit later!
Make it a great Friday!

First “Taste” Of Winter; The Wild Swings Of Autumn…
Updated 10.26.23 @ 6:45a
The next couple days will be the last of temperatures in the upper 70s to lower 80s until next spring. The first of 2 cold fronts will settle into central Indiana tomorrow evening followed by a strong frontal passage Monday. If you rather go right to the punch line instead of reading through the rest of this post, trick or treaters will need the heavy cold gear this year.
A few showers will skirt northern counties later this evening but the lions share of the next 36 hours will be rain-free. A line of showers and even thunderstorms will be associated with Friday evening’s cold front.
A much more widespread, heavier rain will build into central Indiana through our Saturday afternoon. It’s this period, continuing into Sunday where the bulk of our widespread 1”+ rain will come. A smaller axis of heavier totals (2”+) likely sets up shop south of the city, itself.
After a “step down” process to cooler air Friday into Saturday, the bottom will really fall out Monday. This will set us up for a downright cold Halloween (lows in the upper 20s with highs in the lower 40s). Add in winds and the “feels like” will be in the 10s and 20s into the 1st day of November.
If that isn’t enough, trailing upper level energy will push into the area Halloween night and have enough moisture to generate snow showers late into Wednesday morning. A renewed push of gusty winds can also be expected during this time period.
Coldest mornings of this stretch will likely take place next Wednesday or Thursday with overnight lows into the middle to upper 20s.

Dinner Time Rambles: Prospects Of HVY Rain On The Increase And Brief, Yet Potent Early Season Arctic Jab…
Updated 10.23.23 @ 5:45p
I. Today’s model suite continues to suggest quite the unsettled stretch of weather awaits for pre-Halloween festivities. I know, please don’t shoot the messenger. The culprit? A strong autumn cold front stalling out for a time in response to waves of energy riding along the boundary. The end result will likely be a widespread swath of 1″+ rains over the weekend with a more localized 2″+ band. Details will have to be fine tuned as we get closer, but folks with outdoor activities and ag/ harvest ’23 interests should plan on a rough stretch of weather in the Saturday through Monday timeframe.
II. The coldest air so far this fall season will come rushing in on the heels of all of the aforementioned rain in the 8-10 day timeframe. Today’s European guidance is going all-in on a potent early season “jab” of arctic air, including highs around freezing and lows deep into the 20s. Perhaps extreme? Certainly, but this also has merit given where the pattern is. Though this will likely only be a brief intrusion of bitter air (at least by early November standards), I’d certainly go ahead and plan on the growing season coming to a screeching halt in just a little over a week from today.

The Pending Halloween Pattern Transition And Initial Taste Of Winter…
Updated 10.21.23 @ 7:34a
The upcoming week will feature a pattern shift, albeit a transitional one, that will drive unseasonably warm temperatures north into the Ohio Valley and Great Lakes region. This will be on the heels of the first widespread frost of the season Monday morning. Ah, Indian summer at its finest.
A couple of disturbances will try to make inroads into this ridge mid and late week, but will likely struggle in providing much in the way of precipitation or cooler air initially. As we push into the latter part of next week and the Halloween weekend, a larger storm system is anticipated to move east out of the Plains region. This storm will likely deliver the first widespread winter impacts (outside of the mountains of course) of the fall season.
Specifics will be fine tuned as we get closer, but we expect a widespread rain (perhaps a clap of thunder) here next weekend followed by sharply colder weather prior to Halloween, itself.
We’re left with a much different pattern to open November. This is the type regime that will likely lead to the first lake effect snow in the snow belt, drive the 1st widespread freeze into the Ohio Valley, and result in highs in the 40s in the wake of the frontal passage.
Farmers and those with ag interests, we’d suggest wrapping up harvest 23 efforts by mid next week if at all possible. Conditions will certainly become harsher and less favorable by next weekend. More to come…
