Progressively Colder Air Builds Southeast This Week…

After a chilly open to October, the past several days have provided a rebound in the temperature department. Officially, through the first 11 days of the month, Indianapolis is 1.3° above average.

Month-to-date temperature anomalies through 10.9.20

This week will feature (2) cold fronts sweeping through the region. The first front is on our doorstep now and will pass through the area this evening.

Expect a brief shower and gusty winds between 4p and 6p this evening from west to east across central Indiana. Winds will likely gust to around 40 MPH as the front moves through.

Forecast radar at 5p Monday.
Forecast wind gusts at 6p Monday.

Cooler and less humid air will pour into the region tonight and set the stage for a pleasant midweek period.

A secondary cold front will push into the state Thursday and this frontal system will pack a colder punch just in time for the weekend.


Another shot of light rain and gusty winds will accompany the 2nd cold front, but the bigger story will be the sharply colder air. Highs this weekend will likely only top out in the lower to middle 50s with overnight lows into the 30s.

A weak wave of low pressure will be monitored this week for the possibility of spreading a chilly rain (GFS has even hinted at wet snow mixing in at times, but we’re not buying that as of now) across the Ohio Valley Sunday into next Monday. If this system develops, we’d likely be talking about highs not making it out of the 40s during these days. More on this and what the lead up to Halloween has in store later this evening in our video update.

Have a blessed Monday!

Long Range Update: 2nd Half Of October And Open To November…

As the fall season “matures” the same MJO phase last month can lead to a much different weather pattern this month (November and so on). Note how the latest European monthly MJO model takes things through 5, 6, 7, and 8 by early November.

With greater amplitude, I’d say this would take the driver seat behind the pattern evolution into early November, but that’s not the case. Instead, we’ll want to continue to closely monitor the happenings with the EPO and PNA.

Both are pegged to move into favorable phases to bring the chill back into the East as we move through late October.

We think next week will feature a “step-down” process to a much chillier following week (Oct. 17th-23rd).

Oct. 8th-15th
Oct. 16th-23rd

The new JMA Weeklies into the office this morning show a similar pattern evolution:

Week 1
Week 2
Weeks 3-4
Week 1- Surface Temperature anomalies
Week 2- Surface Temperature anomalies
Weeks 3-4- Surface Temperature anomalies

If anything, I’d expect this model to cool further over time in that Weeks 3-4 period. It’s also interesting to see the high latitude blocking shown to remain intact (that can really begin to have more of an impact downstream once to November).

Unfortunately, it’s a continued dry pattern. We’ll have more frequent frontal passages as we move through the back half of the month, but these will likely be moisture starved for the most part. It still doesn’t look like a wholesale wetter pattern will kick in until later in November.
