Not even close (yet). Morch 2012 was to monthly temperature anomalies what April 27, 2011 was to tornado outbreaks; and it set the theme for the rest of that spring and summer. We also had no appreciable snowpack throughout that entire winter, while we had a solid one throughout February this year although the late month thaw steadily gobbled it up by the first few days of March.

My ratio is probably getting dangerously close to falling below the 2:1 ratio. P.S. How’s the weather in Madison these days? As a UW alum who got to experience that epic ‘07-08 winter, has anything close to that happened since? There was a pretty rockin' stretch from late January through the first three weeks or so of February this year. 2007-'08 is still my favorite winter though, despite the occasional torches/thaws. My interests definitely lean toward the "sustained storminess" rather than the "sustained cold/snowpack" column. I was going to UW-Green Bay at the time but spent the long winter break with my parents in Stoughton. 1 Link to comment Share on other sites More sharing options...

beavis1729 Posted April 8, 2021 Share Posted April 8, 2021 An already impressive winter in interior Alaska is going out with a bang, with snow and cold. 2-day snowfall of 13.2" on April 3-4 in Fairbanks, which brought the snow depth to 40". This is the highest snow depth since 1993. Snow depth on 4/7/2021 was still 38", 2nd highest so late in the season (only 1991 was greater). Could be a bad year for flooding and river ice break-up. Fairbanks just set a new record for consecutive days under 40F: (1) 179 days: 10/11/2020 to 4/7/2021 - still active (2) 176 days: 10/3/1965 to 3/27/1966 (3) 171 days: 10/8/1994 to 3/27/1995 With clear skies and fresh snow cover, Fairbanks dropped to -24 on 4/6/2021, which is the 3rd coldest temp on record so late in the season (-24 on 4/7/1986 and -32 on 4/10/1911). It was even colder at some other sites: -36 at Jim River DOT (Mile 138 Dalton Highway); -34 Norutak Lake RAWS; -33 Bettles. There is an even colder airmass lurking for this upcoming weekend, where Fairbanks could hit -25 or -30. Normal temps for this weekend are 40/16. Per Rick Thoman: "By several measures, the Utqiaġvik 00Z Thu RAOB records the coldest April low-level airmass on record (since 1948). Lowest 850mb temp -35.5C; lowest 1000-850mb thickness 1138 gpm; lowest 1000-500mb thickness 4803 gpm." http://ak-wx.blogspot.com/2021/04/even-colder-on-way.html http://ak-wx.blogspot.com/2021/04/extreme-cold-approaches.html 5 Link to comment Share on other sites More sharing options...

Climatically speaking, Fairbanks has very little seasonal lag. This means that in Fairbanks, June is warmer than August, and December is colder than February. It looks like temperatures return to normal next week, and that streak of below 40F temperatures will come to an end. Link to comment Share on other sites More sharing options...

To add some perspective by looking at the data, DJF was above normal at Fairbanks, and if you include November and March in there, the cold season there was slightly below normal. That said, NWS point and click for Fairbanks suggests that -32 could be challenged Saturday morning, which would be impressive. Imagine waking up to -32 degree temperatures in April.

"cold season" stats are often overlooked but I became interested in them years ago. They can often look different than just the DJF rankings. Most notable here was 2013-14. 8th coldest winter on record but 3rd coldest cold season. Link to comment Share on other sites More sharing options...

It's been fairly quiet everywhere else (including Tornado Alley). That said, at least here, we still got a few more weeks until the peak of severe weather season.

Need the MJO to wake things up again...and hope that whatever bizarre confluence of events that made the atmosphere forget it was May last year and in 2018 doesn't re-appear. Not to mention 2019's sequence which mostly failed to live up to its potential, but at least it was something. Last few GFS runs have shown signs of life toward the end of the month but suggest it may be mostly Dixie again...some possibility the Southern Plains get in on the action per the current (14/06Z) run. Not prime time for us yet, but it shouldn't be this much of a nail-biter. As @beavis1729 likes to say about cold and snow in D/J/F, you shouldn't need a bunch of indices to line up just right for potential in A/M/J. You really need an absolutely hostile pattern to prevent it from happening...but amazingly it seems that's what we have been getting more often than not these past few years. It seems the only "season" that's really reliable anymore is hurricanes in A/S/O (except in 2013, lol). 1 Link to comment Share on other sites More sharing options...

It seems the only "season" that's really reliable anymore is hurricanes in A/S/O (except in 2013, lol). When it comes to severe weather I'm weird. I love a good wicked looking sky. And deep down I always wanted to see a funnel cloud. But I don't want so much as a twig to be snapped of any of my trees, let alone lose power. So I guess in the end...im fine with it lacking. That said, severe weather has been far far FAR more lacking here than winter weather and it's not even a contest. Through about 2004, we seemed to always get several instances of severe weather yearly. As snowfall increased the number of strong or severe storms just tanked. I am not sure about regionally, I'm just talking locally. And unlike granddad who for centuries has been falsely claiming winters of his youth were tougher, I have the written proof (and pictures). I've been keeping daily records since 1995. Link to comment Share on other sites More sharing options...
