The coldest 10 day stretch back in February 2015 was .1 warmer as that month was more about the longer duration February cold. 16.8 2026-02-02 16.9 2015-02-21

The most impressive short term cold this winter in the CONUS has been the record breaking cold in Florida the last few days. This goes to my point a few days ago about the big temperature swings and smaller geographic footprint of the cold. So places like West Palm Beach with a very long period of record just tied their all-time warmest winter reading of 90° in late January before falling to their 6th coldest winter low of 30°. This is against the backdrop of that area and all the locations across the CONUS experiencing a much higher ratio of record highs to record lows. It makes the cold stand out more since it’s more of a novelty than the record warmth which usually dominates West Palm Beach was finally able to end their longest streak above 30° since 1989.

The magnitude of the warmth in the West has been much more extreme than magnitude of the cold in the East. So the West has been experiencing historic warmth. While the East has been colder than recent winters, it’s nothing historic compared to our colder winters of the past.

The old forecasters rule was that if the models started showing a major snowstorm in Philly it would keep coming north into our area right up until storm time. This was the case in 1983, 1996, and 2016 when the forecasts started out showing the heaviest snows staying to the south of our area. 2-6-10 was the one exception in modern times. It was the first time in recorded history that Newark recorded less than 1” of snow with 20”+ in Philly. Let’s hope we never see a snowfall cutoff like that ever again.

Unfortunately, 2-5-10 was one of our worst cases of suppression as the record snows went just to our south.

Very impressive Arctic outbreak possible next weekend as a lobe of the polar vortex is forecast to dive into the Northeast. Places like NYC have a chance to drop lower than this weekend since the winds look to be stronger with more of NW flow and stronger high pressure to the west. Instead of the light winds like we had this weekend which didn’t transport the coldest air into the heat island. My guess is that we will finally get a thaw beginning a few days later as the entire polar vortex shifts back closer to the Arctic and Asia.

We finally got the Southern Stream to become active over the last 7 days. So it delivered our first KU Benchmark storm since 2022 with widespread 10”+ amounts across the Northeast. The benchmark track which is a prerequisite allowed several stations to finally have a 25” season before we even reached February. But since the Western ridge has been so overpowering this winter, the big storm last weekend occurred with a deep trough out West and a transient Southeast ridge. So we needed a relaxation of the ridge for our big storm. One of the December clippers also occurred with a trough out West and a transient Southeast ridge. But that event was Northern Stream dominant so there weren’t widespread 10”+ amounts since the Atlantic and Gulf moisture couldn’t get tapped. The ridge and trough axis was too far east today for the big ocean storm to come closer to the coast. So the Western ridge was just a little too overpowering this weekend. Same theme for much of the winter outside one of our December clippers and the big storm last weekend. The other thing is that getting two 10” events only 7 days apart has only happened once in our area since the 1990s. This was the rare twin 10”+ snowstorms only a few days apart in February 1994. Even during the phenomenal 2010-2018 snowfall run we needed at least several weeks to reload the 10”+ snowfall pattern. The best run from this period was the 60”+ in 33 days from December 2010 into January 2011. But the storms were spaced out at longer than 7 day intervals. Overpowering Western ridge relaxed for the clipper and benchmark storms Late January benchmark track Ridge and trough axis today just a little too far east

Here is another example of how in the past we often had coast to coast cold at durations lasting a month to occasionally the entire DJF winter season. December 2025 was the 39th coldest in the Northeast and the same average temperature of 24.2° as 2017 was. But this is the first time an average Northeast December temperature in this range occurred with all-time warmth in the West near +15° above the long term averages. Back in 2017 we did have some warmth in the Southwest but nothing as extreme as this December was. The other years with that were within about 0.6°which the Northeast was this December had the cold extending to the West Coast. So we can see the warmth expanding out of the Southwest over time and increasing in coverage and magnitude.

That is just one example. The total amount across many locations and timeframes is too vast for me to list in one thread. But I have plenty of more examples for other individual locations and time periods.

This January was much warmer in the Arctic and the CONUS than 1977.

2019 was the warmest January at Rockford, IL to feature a -25° or colder reading with the big temperature swings that month and a high over 50°.
