Warmth Dominates Now, But A Cold & Wintry Pattern Is Lurking For The Holidays…
The short-term weather pattern will continue to be dominated by rather “boring” conditions for this time of year, along with much milder than normal air. A weak frontal system will swing through here Thursday and while a light shower is possible, that’s really the only significant (if you want to call it that) weather feature through the upcoming 7-10 days.
In addition to the rather quiet weather, relative warmth will dominate as we open December. When “normals” feature lows in the upper 20s and highs in the lower 40s, actual overnight lows will only fall into the low-mid 30s and highs will reach the middle to upper 50s.
When we look ahead, the shelf life of this warmth is certainly limited. The GEFS showcases this shift in the pattern from a warm open to the month towards a much colder pattern very nicely. The GEFS has other model support, as well.
This is the type of dramatic shift in the overall pattern that not only threatens to “lock in” a colder than average regime, but potentially lead to plenty of wintry mischief to boot, and just in time for the holiday season.
There’s teleconnection support for the wintry shift, as well, leading to further confidence of a significant move towards cold, and potentially snowy/ icy, conditions as the true holiday and Christmas season approaches.
To summarize, while unseasonably quiet and mild conditions will rule in the short-term, Mother Nature sure seems to have an attitude of making up for “lost time” in the medium to longer range. This is the type pattern that we’ll have to monitor the potential of some sort of leader-follower scenario as the transition from warm to cold takes place, and given the blocky nature of the pattern, it sure seems like we’re heading into a busy time of things from a wintry perspective mid and late month.
Perhaps this will be the scene as Christmas time nears across the Mid West, including central Indiana? Time will tell…

Sunday Morning Notebook; Active Pattern Remains…
For a change, the past (7) days has been generous to central Indiana from a precipitation perspective. As we’ll discuss, a new rain maker awaits this week.
A look at rainfall totals over the past 7 days, courtesy of weatherbell.com.
Officially, IND sits at 0.26″ above normal, month-to-date.
It’s also been an incredibly warm start to the month (IND is running 10° above normal, month-to-date) and that warm theme won’t change through the near-term.
An all-too-familiar pattern engulfs the country late week. This will showcase more “bonus” summer-like conditions, locally, that will include highs approaching 80° next weekend with a strong southerly flow in place. Additionally, early winter-like conditions will continue to impact the western high ground. The pattern definitely represents a Nina look.
The southeast ridge will provide more bonus summer-like conditions next weekend across the eastern half of the country.
In the shorter-term, a new rainmaker will move across the Ohio Valley Tuesday into Wednesday. This will spread showers and embedded thunder across the state Tuesday PM into Wednesday. In general, this storm system should deliver 0.50″ – 1″ of rain, but there will be locally heavier amounts.
Thereafter, dry times will settle in along with slightly cooler temperatures. Let’s remember it was only a few days ago where modeling suggested a “pop” of the season’s coldest air thus far. No longer is that the case, and while it will turn briefly cooler, temperatures will still remain above average.
A southerly air flow will return late week and help boost temperatures next weekend, along with continued dry times through the balance of the weekend. From this distance, our next storm system should arrive late Sunday or early Monday in the form of a cold front.
Looking longer-term, there are indications that colder conditions loom as we wrap up October and head into November and we’ll discuss this in more detail later this week…
