All Activity

The historical Max and anomaly is March 1960. Maybe the month I dream about experiencing the most. In March 1960, the Northeast saw a relentless pattern that produced 7 distinct measurable snow events for the Harrisburg (MDT) area, totaling that record-setting cumulative amount. It wasn't just one "Superstorm"; it was a "parade" of systems that kept the ground white for nearly the entire month. Here is how that active March unfolded for Harrisburg: March 1960 Storm Timeline (Harrisburg/MDT) | Date | Snowfall Amount | Notes | |---|---|---| | March 3 | 10.5" | The primary "anchor" storm of the month. | | March 10 | 1.8" | A cold-sector clipper system. | | March 16 | 3.2" | Moderate overrunning event. | | March 17 | 3.0" | St. Patrick's Day system. | | March 22 | 2.0" | Late-season coastal influence. | | Minor Events | 2.1" | Combined totals from minor dustings (March 4, 7, 8, 21, 24). | | Total | 22.6" | (Catalog sum for distinct events) | Prior to this month that winter had produced 27" of snow, similar to us now. But March was notice to all the new decade was a different beast Sent from my SM-S731U using Tapatalk

No Ruth's Chris for you.

Now it has a half inch or less except east of the city

Neither do I.

It flips around too much for my liking. Too many Big run to run changes; if 0z mesos follow suite then I would take note.

Just catching up on reading all these ob posted for this storm. Attached is the CG plot from around 3am Monday. That is a *lot* of CGs for S+ bands well N in the cold sector of a coastal, looks like several dozen over a 2 hr period. I can't recall that so many near or over SNE for a snowstorm, even the Bliz of 93. On the BOX radar from 257am Mon attached, the uber snow weenies here I bet can answer this question. That much solid 30 dBZ in multiple bands for for a SNE snowstorm? Often it is more peppered dBZ 30-35 within 20-29 dBZ for bands like this, but not so solid. So how does this radar rank for S+ weenie bands? And BOX radar was not running "hot." I checked OKX at the same time and the dBZ matched over SE CT.

Looks like we are 10 inches above normal compared to the normal this time of year. Still time to add on. Can we get 50 or even 60. Still plenty of time.

It is intriguing to think of the societal impact if that SE Mass firehose was a bit north and going from BOS to HFD… instead of like Long Island to PVD/TAN ENEward. I would’ve enjoyed that low tracking over PVD to BOS, lol.

The Regime Transition Probability Map is a visualization of a Markov Chain transition matrix, designed to quantify the likelihood of shifts between specific atmospheric states. It represents a century of regional snowfall data processed through a K-Means clustering algorithm. Statistical Mechanics of the Map * Axes: The vertical axis (Current Cluster) defines the point of origin, representing the weather regime of the most recent event. The horizontal axis (Next Cluster) represents the predicted destination for the subsequent atmospheric event. * Probability Density: The numerical values and corresponding blue shading represent the probability (0.0 to 1.0) of a transition occurring between any two clusters. A value closer to 1.0 (darker blue) indicates a high statistical probability, while a value closer to 0.0 (lighter blue) suggests a rare or unlikely transition. Current Regime Analysis: Transition from Cluster 3 Following the high-intensity coastal event on February 23, the atmospheric state is currently positioned in Cluster 3 (Extreme Synoptic). Analyzing the Row 3 data provides the following probabilistic insights: * Pattern Persistence (3 to 3): The probability located at the intersection of Row 3 and Column 3 quantifies the likelihood of the atmosphere remaining in a high-intensity coastal redevelopment cycle. * Regime Decay (3 to 2): Historically, late-February Cluster 3 events exhibit a strong statistical trend toward Cluster 2 (Clipper / Fast-Moving). This represents a transition from high-payload moisture systems to lower-accumulation, high-ratio arctic systems. * Inland Transition (3 to 1): The probability of shifting to Cluster 1 (Miller B / Overrunning) indicates the likelihood of the next system following an inland track rather than the coastal track observed yesterday. Probabilistic Representation The map demonstrates that weather patterns are not random but operate within a set of statistically favored transitions. For a Cluster 3 point of origin, the high concentration of probability in the Cluster 2 column suggests a regime shift toward diminished regional totals. This indicates that while extreme events like the one yesterday are significant, they are statistically followed by a period of lower intensity as the seasonal atmospheric steering flow begins its spring transition.

6" yesterday (and Chris we are well over 60" so far, last year year 42 1/4"+/-, year before 32") I happy with this season so far, despite missing on yesterday big dog.)

me too how can u say no to snow! wtf

Quiet hurricane season inbound. Wow, sucker hole across CT. Now this is a winner. Us valley dwellers get screwed way too often in all kinds of setups.

@The 4 Seasons, not sure if I told you, but couple friends in Warren and Goshen both measured, 13" and 14.7" respectively, I see a 6" total that looks like it's about Northfield area, and I can say personally I saw way more than that unless they forgot to update, but it's out of place, and mine is 15.2" not sure who recorded the 15.6, but like I said, I'll take the extra stat pad. Couple of coaches I know in New Milford were both over 19" but map already shows it. just an update for the archives.

Well this town goes from like 300' to over 1000' and I'm at 540'. I'd def take your location on the hill over mine. 1k to 1k I bet there isn't much diff. Our latitude helps in swfes and maybe we catch the stray streamer but we also get subsidence here more often and are further away from the moisture in ocean storms.

Not sure how long it will last with the PV taking a big hit.

I will take it

HRRR getting drier FWIW

Mine is 60” . I’d have to believe Burptown is higher than here . More like 65-70

Not shocked given some ongoing issues in that area. I do think 3 inches is the possible, but I have stayed under that other than indicating spotty areas; yet to be determined. Odd they used wording of heavy band of snow... They are one of my clients and I did not use the term heavy nor 3"expected. Concerns over ongoing road issues and a period accumulating snow; certainly! Enjoy the time with the rugrats, can never get enough time with the little ones.

What did you get?

gonna be a helluva lot longer than that.

If anyone wants it I have daily snowfall, snow depth, max temperature, min temperature. data so far for 1/1/1925 to 12/31/2025 from about 35 stations across Virginia, Maryland, Delaware, Pennsylvania, New Jersey, New York, Connecticut, Rhode Island, Massachusetts. I was able to use Google Colab and python script to combine it all in csv. It's big for a csv, over a 100mb. I converted it into a paraquat file to use more easily in python and that's just over 9mb. Regime 0 (Steady Coastal - Miller A): Features three sub-regimes. Variant 0.1 is the outlier here, representing high-moisture coastal systems that dump significantly more than the baseline. Regime 1 (Miller B / Overrunning): Highly frequent but generally lower in average intensity. Variant 1.2 is the heavy-hitter for this category, often associated with redeveloping systems that "capture" deep moisture. Regime 2 (Clipper / Fast-Moving): This is your most frequent baseline. Variant 2.0 represents the "peak" clipper—fast, cold, and efficient, occurring nearly 500 times in the century. Regime 3 (Extreme Synoptic): The "Big One" category. Even its "weakest" variant (3.0) averages nearly 3 inches of snow, while the primary peak (3.1) averages 4 inches across the entire regional station network. The graphic also includes the Event Counts for each sub-cluster, allowing you to see which atmospheric setups are common versus which are rare historical anomalies.

compared to some of the snow maps, sure. but most guidance hit well. i remember when the euro had that thing locked in from a week+ out, and only lost briefly it for a run or two several days out.
