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.

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.
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

An area of low pressure continues to organize in northeastern MS this afternoon and will move northeast into the lower Ohio Valley before transferring energy off to a secondary (and eventually “primary”) low that will take control Sunday off the Mid-Atlantic and southern New England coast.
Rain will lift north into central Indiana through the late afternoon and evening, falling moderately at times tonight. As just enough cold air pours into the backside of the low, rain will transition to a wet snow after midnight. We note high resolution guidance is also becoming more “excited” about the potential of a narrow deformation band of precipitation that may setup shop across portions of central Indiana into northeastern parts of the state Sunday morning. If this does, indeed, take place, a wet “thump” of snow to the tune of 1″ to 2″ can be expected by 9a Sunday. That said, even hours away from this event, “bust potential” is still much higher than normal. Should we not realize the narrow band of heavier precipitation rates, it’ll be difficult if not impossible to get the column to cool enough to generate a band of accumulating snow.
All in all, still a far cry from anything significant, but this could surprise a few folks Sunday morning all the same. Most, if not all of this wet snow will be confined to grassy and elevated surfaces, but there could also be a few slick spots early Sunday morning during periods of heavier snowfall rates.
Speaking of Sunday, we turn quite blustery with northwesterly winds gusting upwards of 30+ MPH and highs in the middle 30s. Dry conditions will return after the early morning snow departs.
