We posted this to our Twitter page last night (@indywx), but wanted to make sure we posted here, as well. We’ll discuss this in more detail later tonight. In addition to this morning accumulating snow event, we’re also tracking (3) additional accumulating snows in our near future. Keep the shovels handy, friends!
Much more later today! Travel safely if you must be on area roadways today.

Our snowy pattern is rolling along with no signs of stopping anytime in the foreseeable future. We forecast 2-4″ of new snow tonight through Tuesday morning. A combination of an…

We’ve talked a lot about the relentless weather pattern that has kept our immediate region in what seems like a snow globe since mid December. Of course we’re on pace…

As I write this, central Indiana is undergoing yet another winter storm that will dump a fresh 3-5″ of snow by midnight Sunday morning. We’re well on our way to reaching the snowiest January ever at IND and with the pattern ahead through the end of the month, we very well may just do it. Before we discuss snow, let’s take a look at the coming shots of arctic air.
While no weather event is identical to another, it’ll be rather easy to compare the coming arctic attack to that which we experienced earlier this month. That said, there are a couple of important things to consider. This next wave of arctic air will blow into town when “average” temperatures are at their lowest of the calendar year. Secondly, data continues to suggest this isn’t just one arctic plunge, but more of a longer duration event when compared to the bitter blast earlier this month. Needless to say, we’ll need to go into our preparation mode for another round of severely bitter air for the upcoming week.
Let’s look at the model data- note the eastern trough re-amplifying through the period, backing up our idea that this is a rather prolonged arctic event ahead. As of now, we focus on late in the work week/ next weekend when air temperatures plunge to their respected lowest values (below zero), but want to stress the entire period will be downright cold (much colder than normal), and the long duration event will put more strain on pipes, etc. than a quick-hitting, in and out, arctic outbreak…
When we talk about a longer duration arctic outbreak we’re talking about the possibility of below zero temperatures Wednesday night, Thursday night, Friday night followed by another arctic push that sends lows below zero next Sunday and Monday nights. Stay tuned.
The winter of 2013-2014 is off to a record pace as far as snow totals go. While we’re not staring at any sort of significant winter storm over the upcoming week, a fast northwest flow can present challenges galore, and any clipper stands the chance to be an “overachiever” as they race southeast over the upcoming week. We fall back on the disclaimer we’ve mentioned in previous posts with clipper systems…the track and strength will be tough for forecast models to iron out until 24-48 hours out. Secondly, with arctic air firmly in place, snow ratios will be more common around the 20:1 level as opposed to the “normal” 10:1 ratio.
Let’s look at the upcoming snow threats over the next several days…
Our first light snow threat blows in tomorrow night into Tuesday.
We then target Wednesday night-Thursday.
Finally, we’ll keep a close eye on late week/ next weekend for yet another potential snow event.

The coming several days will result in a continuation of adding to an already expanding snow pack across central Indiana. (We think a 3-5″ band of snow falls for some central Indiana communities Saturday evening and we’ll post on this Friday). That “ups the ante” for a potentially second round of cold air that flirts with records as we begin to wrap up the month of January and head into February.
Here’s a look at the latest ensemble package out towards Days 8-10 (Jan 24th-26th time period) and we note a near text book pattern for a severe arctic outbreak across the eastern half of the country. We want to point out the high latitude blocking combined with a frigid cross-polar fetch. The GFS and European forecast models (amongst a slew of others) are in excellent agreement on the brutally cold pattern setting up shop, which only adds to our confidence level.
Okay, okay…the fancy maps above may look confusing to some (and rightfully so), so what does all of this mean to you? We think we’re looking at multiple nights that feature below zero low temperatures across central Indiana, and potentially in the double digit below zero range yet again. (Wind chills will be even colder). We’re looking at the type of cold pattern that could produce multiple days with high temperatures in the single digits to lower teens.
Yes, the winter of 2013-2014 just keeps on keepin’ on and truly shows no signs of letting up. Hunker down, friends!
