  1. Sorry to bother, but it doesn't look like Twitter (or X I guess is what it's called now) links embed to AmWx anymore, so they're not viewable. Can you summarize the tweets you're sharing? In your own words preferably.
  2. Ridiculous UHI effect up in Albany
  3. That's because JB posted the control run, the operational CFSv2 currently only runs through November.
  4. he has correctly predicted 38 of the last 20 warm winters after all.
  5. 1/26/11 was the the first one I can remember "tracking", being glued to TWC coverage, cycling back from the TV to the window, waiting for a changeover. It must've happened in an instant, going from pouring rain to a near whiteout, by far the highest impact for a single-digit snowfall I have ever seen. 8 inches of heavy wet snow that caused a 3 day power outage (nearly as long as Feb 2010's snow blitz), and a prolonged snowpack after. Those high impact rain to snow events (1/3/22 is in the same realm as that one) have always been a favorite of mine. There's just something about a dreary environment transforming into a powder keg at a moment's notice. Most memorable stretch of winter has to be Feb-March 2015. Nearly every flavor of snow event, and some historic cold that we might never see again.
  6. This recent 2 month stretch marks the first time DCA has had consecutive BN months since April/May 2020. Coldest 5/1 -> 6/30 (69.3F) since 2005 (68.7F). Nowhere near 2003's average for that timeframe of 66.4F, which stands as the coldest May/June period in DCA's history and coldest at any official DC site since 1927.
  7. I remember reading that some areas in Siberia were the coldest since 2002. Maybe next year we'll get our 2003? In any case I'll remain hesitant about an El Nino being the remedy we need. The 06-07 and 94-95 style Ninos still lurk, but it's definitely a step up for our chances.
  8. I think that was the March 17 2014 system. This is likely what PSU and Heisy are referring to. Potent Arctic airmass helped aid in the system's snowy characteristic despite being anafrontal. 4.8" DCA, 6.2" BWI, 9.5" IAD That airmass also set a few records in the wake of the storm, where IAD fell to 6 degrees on the morning of the 6th and 2 degrees on the 7th.
  9. 17-18 and 18-19 had a couple of these, but considering that those are the only examples since pre 15-16, it doesn't bode well. The only consolation of all of this is what I mentioned a while back in your thread where -EPO/+PNA driven patterns seem to be snowier than they used to be before. Like how people assumed 13-14 was an uber lucky fluke given that predominant pattern but then Jan-March 2015 happened. It'll never make up for the snowfall deficit from lost margins on our more typical patterns, but it's the very least of note for when we're dealt those patterns (which given our incoming -PDO might not be that helpful.. although I did read that the current-PDO regime might've started in the 2000s? Hopefully that's the case.)
  10. 850s for DC and NW actually never go below 0, but it doesn't matter if the thermals are torched. Crazy how we've gone through the November-March timeframe dealing with mid 30s rainstorms
  11. GEFS changes reflect OP for wave 1. stronger h5 low, more ridging out West, and a slightly stronger 50/50 low.
  12. Most of our cold snaps nowadays seem to stem from a string of rainy and cloudy days that disproportionately skew high temps lower, so something like that is pretty impressive. If only that cold was there during the Dec-Feb timeframe
