“Steady As She Goes:” No Need To Change Ongoing Ideas Of Milder Than Normal Open To February Followed By Cold, Wintry Pattern Thereafter…

Updated 01.29.24 @ 5:42p

Let’s get to the headline right out of the gate: Winter is far, far from over. While we don’t have any significant changes to our ongoing long range pattern ideas, I did want to touch on the overall regime for February into March during this evening’s discussion.

Subsequently, we’re also continuing to lean into the milder than normal pattern that will be with us as we close January and navigate the first 1/3 of February. Today’s medium range model data backs this up well.

Day 1-5

Days 5-10

Days 10-15

Overall, the next couple of weeks should also result in a drier than normal pattern, locally.

It should come as no surprise given the teleconnection suite (all in warm phases, with the exception of the PNA which will result in cooler anomalies at times across the Southeast region). We note these same teleconnections shifting towards the colder phases around, or just before the 10th of February. The Madden-Julian Oscillation also is in the notorious warm phases.

Before 2/10, any cold will be fleeting and nothing significant given the time of year. Overall, an unseasonably mild pattern will dominate.

Post 2/10, we’re going to see a shift towards colder times. A lot of this has to do with the alignment amongst the teleconnections. Throw in the MJO heading into the frigid (for this time of year) Phase 8 and you have the potential to eventually see the pattern deliver the magnitude of cold we just saw come late February. (In case you missed it, we already set the bar on the type of cold we envision developing late February).

Given the NAO heading into the tank by this point, there’s fear this particular round of cold would likely have more staying power than it’s January predecessor. “Phase 8 MJO WITH a strongly negative NAO?” Look out below…

Interestingly, the NEW European Weeklies are going right to this set-up and perhaps the most bullish I’ve seen over a 30-day period from this distance. Winter is far, far from over, indeed.

A Quieter Pattern To Close January; Open February…

Updated 01.28.24 @ 7:07a

The narrow but more organized band of locally moderate-heavy precipitation failed to materialize overnight. The result is a busted snowfall forecast. Sure some are dealing with wet snow this morning, but the type of precipitation rates weren’t achieved to cool the entire column of air enough to allow the accumulating snow axis of 1”-2” to materialize.

Regardless of what type of precipitation you’re seeing this morning, this will all pull out of the state around lunchtime. Western portions of Indiana will dry out much sooner.

We’ll be left with blustery conditions today, including north, northwest winds that will reach speeds north of 30 MPH at times.

Expected wind gusts of 30+ MPH through the afternoon

With all of this said, the great news is that the balance of the upcoming week (into next weekend) will be significantly quieter around these parts when compared to this past week. We’ll watch a clipper system that will likely deliver a cold rain and/ or a wintry mix Tuesday morning into the afternoon but this shouldn’t be a big deal across central Indiana.

That’s all she wrote on the precipitation front heading into next weekend. Heights will build over Hudson Bay (Hudson Bay block) this week and force a more active pattern to our south late week. While we’ll have to continue monitoring the potential of interesting times to our south (lower Ohio Valley, TN Valley and Deep South) going into Friday and the weekend, this upper air pattern should keep our immediate weather much quieter, aside from a “back door” cold front that will pass through here dry. We will certainly notice a much colder time of things developing during this period, along with gusty winds at times.


Looking Ahead: The overall pattern should feature a milder than normal regime (as a whole), along with drier than average conditions to close January and open February.

Week 1

Jan 28-Feb 3

Week 2

Feb 4-10

VIDEO: Changeable Weather Tonight Into Sunday; Hudson Bay Block Forces Interesting Setup Late Next Week…

Updated 01.27.24 @ 8:25a

We’ve noticed a north and western trend with respect to our storm system tonight and early Sunday morning. Before we get there, it’s another gloomy start to the day (becoming the norm, huh?!). Rain will build north into the region this evening and fall at a moderate clip at times. We still anticipate a wet snow band to develop on the northwestern periphery of this rain shield overnight and Sunday morning and the video dives in further around current thinking.

Down the road, a Hudson Bay Block will present additional challenges and the potential of another “interesting” setup late next week. This blocking pattern will help “string out” a stronger storm threat late week and force just enough cold air south where the potential of a winter storm threat will be on the increase across portions of the lower Ohio Valley region and Appalachians. More on this threat as we progress through the week ahead.

Wet Times Give Way To A Drier Week 2; Unseasonably Mild Open To February…

Updated 01.24.24 @ 6:09a

Week 1 remains significantly wetter than normal across not only our neck of the woods but a good chunk of the East.

This will give way to a quieter Week 2 timeframe.

There’s some threat that the southern tier and immediate eastern seaboard never is fully able to relish in the magnitude of the warm anomalies the majority of the rest of us will see as we roll through early February. Just to reiterate, as much as we believe cold, wintry weather returns in February, it’s not after a significant period of milder times (compared to average) to open the month- likely the first 10-14 days.

Just how mild are we talking? Several days with highs into the 40s and even 50s and overnight lows in the low to mid 30s. This compares to early Feb “norms” in the low 20s and highs into the upper 30s. It’s a byproduct of the MJO and alignment with the teleconnections (PNA aside) in the warm phases. As shown Monday in our LR video, we believe this all flips around in a big way later into the month, continuing into March.

In the short term, additional waves of rain (and dense fog) will keep things gloomy around these parts. Most widespread rain will come at us now through late morning before returning Thursday evening-overnight. Most rain gauges can expect to pick up an additional 0.75” to as much as 1.25”+ during this time period.

Modeling continues to differ in a major fashion with the weekend storm. The GFS is further north with heavy precipitation and a transition to leftover snow showers, locally while the European takes the suppressed route. Today will likely bring alignment between the two solutions. . .

Tuesday Morning Rambles…

Updated 01.23.24 @ 7:11a

Overall, we don’t have any changes to our ongoing ideas from last night’s video. If you didn’t have an opportunity to catch that, we encourage you to do so as it highlights our medium and long range thoughts in more detail.

The focus will change from one of ice to periods of rain (and dense fog) through the remainder of the week. We note multiple waves of more widespread rain that will ride into central Indiana over the next few days. While it won’t rain the entire time, an extended period of gloomy conditions will unfortunately be with us as we navigate the next few days and kick off the weekend.

Periods of rain can be expected through the remainder of the week.

Speaking of the weekend, we continue to closely monitor an area of low pressure that appears to take a classic track for a heavy snow dump around these parts. The problem? Cold air is fleeting and it’ll take the perfect combination of track, timing, and precipitation rates to generate anything meaningful from a wintry standpoint, locally. As of now, we favor this “sweet spot” to lay just north of our immediate area, but we’ll continue to closely monitor.

That brings us to our final point this morning and that’s wanting to ensure we drive home the idea here of an overall milder to significantly milder than normal pattern over the upcoming 10-14 days as a whole. While we’re incredibly bullish on winter’s return, we’re equally as impressed by this overall milder signal in the short to medium term.
