Catching Up And Looking Ahead…

From the IndyWx.com family to yours, we wish you a very happy Thanksgiving! Thank you for taking the time to read our content daily and for all of your support over the years! We appreciate it more than we can tell you.

After one of the coldest Thanksgivings’ on record (official IND high Thursday was 31°), Black Friday shoppers are having to bundle up against blustery and frosty air (don’t worry, we won’t start singing Christmas carols on here). It’s just a continuation of a brutally cold November to date.

A byproduct of the cold pattern is also a drier than normal pattern, albeit slightly so after last weeks rains.

Note Thanksgiving snow cover is impressive for the second straight year from a national perspective. See the clipper system that deposited snow to our west Thanksgiving eve and the nor’easter snow east.

The upcoming 7-10 days will feature a milder pattern, but still with plenty of challenges. After a cold Friday, temperatures will moderate courtesy of a southwesterly air flow this weekend. Along with the milder air will come clouds and light rain/ drizzle.

Colder air returns Monday and the combination of cold high pressure north and a boundary lurking just to our south will keep us on our toes this weekend for possible changes. Northward shifts happen in modeling from mid range to short range from time to time and we’ll keep a close eye on things.

Towards day 7 a milder rain storm is on the models.

It’s all part of a “topsy-turvy” pattern in the short to medium range as noted on the latest GEFS temperature anomalies. After the mild spike this weekend we chill early week.

Longer range, we remain bullish of a heavy-hitter winter for the region. SSTs are aligning in classic form that feature colder and snowier than normal conditions across our region.

The latest JAMSTEC agrees on a cold winter locally.

Note the Madden-Julian oscillation (MJO) rumbling into the colder phases of 7,8, and 1. This has sparked interest particularly mid and late December for an uptick in wintry potential…
