  1. Really a warm 500mb pattern shaping up on models, starting a few days after this storm.
  2. Having a hard time changing over here so far. A few big flakes were mixing in, now it's back to light rain
  3. 22z RAP is looking really good at hr21.. west of the 18z GFS with trough. Sometimes RAP and Hrr get a little storm happy, but sometimes it does catch an oncoming trend for heavier banding as well
  4. It's actually a myth that Nina's favor the coastal areas. Randomness from not enough analogs. The La Nina main effect is a stronger North Pacific High, which is a slight SE ridge correlation in the cold season. The patterns aren't always uniform El nino or La nina either, there are many other factors that cause what happens.
  5. It's not that bad because shorter wavelengths give us a favorable H5 low in the Gulf of Alaska. Our biggest snowstorms historically have that -H5 anomaly
  6. It's actually not a big anomaly, because we have a 50/50 low and strong Gulf of Alaska 500mb low. NAO is technically positive, but there is ridging left over from the previous -NAO over the Hudson bay/E Canada, with a trough underneath of it. 500mb pattern close to us in latitude and longitude is pretty favorable.
  7. 15z RAP keeps it rain for a while along I-95 while heavier rates change it to heavy snow in eastern MD/DE. Weird run.
  8. NAM throws a nice band back west Monday morning. Has the coastal low at 966mb
  9. Guess the super warm temps yesterday and high of 50 today isn't going to matter much.. I'd much rather it snow than be right lol
  10. Let's see. These types of situations might go with the models that are a few degrees warmer. I'm not just saying that - many storms hold the warm air when they are riding a frontal boundary like this, especially around DC.
  11. I'm sure it's been mentioned but the 6z Euro is really warm. I was thinking models would start gravitating over to the GFS yesterday, when it was consistent and increasing every run, and other models were starting to trend. That was like 6 runs in a row with a near blizzard! We just don't do big snows without an optimal setup these days. These frontal boundary stationary fronts, with us being on the warm side, always go this way.
  12. When it starts warming at the surface by April, we'll see which regions are going where.
  13. Really warming up in the eastern-subsurface. Probably going to start to surface in the next month or so. SOI isn't on board yet, but it has been lagging the last 3 years: 25-26 RONI Nina: the monthly SOI never went >+10 until October '25 24-25 RONI Nina: the monthly SOI never went >+10 at all 23-24 Strong Nino: SOI was Neutral until May 2023, when the El Nino began. Feb-March-April 2023 average SOI was +2.7/month.
  14. Colder Spring probablity? AO/NAO/AAO run in decadal patterns, and run pretty together. Sept-Dec 2025 had a pretty good run of -AAO: 2025 -0.080 -0.271 0.733 1.138 0.509 0.209 0.753 0.357 -0.709 -1.236 -1.324 -1.136 That rolls forward to a -NAO signal for the following N. Hemisphere Spring (+6 months) [map correlation is default positive, with both sides included, so for -AAO it's opposite]
  15. 5 month SOI.. Oct-Feb 25-26 is still going to be the highest since 2022. And we're seeing more of a Nina pattern here in the 2nd part of February and March, despite warm subsurface
  16. Warmer overall right now, but not a "classic warming" This Winter is going to finish with greater warm anomalies than cold anomalies at 10mb.. which matches QBO. For the 4th Winter in a row.
  17. SOI has been lagging the last few years 25-26 RONI Nina: the monthly SOI never went >+10 until October '25 24-25 RONI Nina: the monthly SOI never went >+10 at all 23-24 Strong Nino: SOI was Neutral until May 2023, when the El Nino began. Feb-March-April 2023 average SOI was +2.7/month.
