  1. Pretty impressive warmth for North America as a whole for the first half of February.
  2. The weeklies are going all in on phase 8 as we approach the Presidents Day period.
  3. That Arctic outbreak fit our recent pattern of having a near 60° day within a week of dropping under 10°.

  4. At least we are doing better than Buffalo.
  5. Close to the cloudiest January since 1973 on Long Island at 63% now. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=45&network=NY_ASOS&zstation=ISP&hour=9&year=2024&month=1&_r=t&dpi=100&_fmt=png
  6. We got a nice follow up storm to the east of NYC in early February pushing us up to around 40”. It gave JFK its first 40/40 winter.

  8. We haven’t had a warm and dry winter since 2001-2002. All our warm winters since then have been wet with either snow or rain. Probably the most winter bike rides that I ever got in on the Long Beach boardwalk.

  12. The 500 mb pattern was closer to La Niña with a deep trough out West and a Southeast ridge. But the raging STJ with all the precipitation was classic El Niño. So a bit of a combination pattern as a function of the much further than west forcing for an El Niño in January.
  13. I was talking about longer range and not inside day 7.
  14. Just look at how much the Euro monthly struggled with its January forecast issued back in December. It was going with something similar to a stock El Niño 500 composite in January. But instead we got a more Niña-like 500 mb pattern with a much stronger STJ due to the continuing El Niño. But the forcing from the Eastern IO into WPAC was missed. This is a common theme of the weekly and monthly model runs since the 15-16 winter due to the rapid expansion of the WPAC warm pool. Forecast Verification
  15. I think you continue to miss the point. Forcing west of the Dateline is a warm pattern for us here in the East. One of the biases exhibited by the models longer range is to weaken convection too quickly in this region. The forcing in the entire area around the WPAC warm pool has greatly surpassed the long range model forecast this winter and most winters since 15-16. This is a long term change which is independent of the El Niño this season. It’s the main reason why NYC is on track for a record 9 warmer than average winters in a row. Beyond the 2nd week of February, it’s still possible the convection can shift further east allowing something resembling a February El Niño pattern as we approach Presidents Day week. But we’ll have to just wait and see.
  16. Yeah, the record +30C SSTs are holding the forcing in place longer now to the west of the Dateline. The old runs from a week ago were more favorable had the convection rapidly weakening. So it looks like the 2nd week of February will actually be warmer than the first week now. New runs stronger forcing west of the Dateline and warmer 2nd week of February Old runs weaker forcing to the west of the Dateline and colder pattern for 2nd week of February
  17. Another winter with top 5 and top 10 warmth around the region to date.
  18. This January is another example of how the La Niña background state of recent years can emerge even during a borderline super El Niño. It’s the result of the record IO to WPAC SSTs focusing the forcing closer to where we would expect to see during a La Niña. So we get a Southeast ridge pattern with 80° record warmth in DC. It’s an interesting combo with such a strong El Niño STJ in place.
  19. Islip is getting very close to its cloudiest January on record using 9am observations. https://mesonet.agron.iastate.edu/plotting/auto/?_wait=no&q=45&network=NY_ASOS&zstation=ISP&hour=9&year=2024&month=1&_r=t&dpi=100&_fmt=png
  20. It almost happened in 2010 and 2011. But those years had droughts in the East. We have been very wet since then. So probably not possible without a drought. Remember, October 2019 had a flash drought which boosted our area to mid 90s. We have a much higher population and electric demand than areas of the US that typically experience 110°+. So they might start rolling blackouts to preserve the grid until demand drops off enough.

  21. We are just fortunate that these monthly maximum temperature extremes since 2015 have occurred closer to the cool season. Not sure if the power grid is up to the record demand 110° during the summer would produce. That’s roughly what a February 2018 and October 2019 magnitude warmth would look like in July.

  22. Closer to a La Niña January 500 mb pattern for the US even though it’s a borderline super El Niño. Very impressive how the MJO really shaped this pattern due to the record SST warmth from the IO to WPAC. The Euro seasonal was going with a stock January El Niño 500 mb composite back with its December forecast.
  23. It’s pretty ridiculous for DCA to even go above 75° in January during an El Niño which is supposed to be cooler in the Mid-Atlantic. All the previous years were La Ninas or ENSO neutral.

  24. The Pine Barrens are one of the most densely forested areas of Long Island and the official weather BNL equipment is located in a clearing. That’s the national and global standard for official weather observing sites that measure temperature for meteorological purposes. But under canopy temperatures are mostly limited to studies about wildlife and biology. https://www.bnl.gov/weather/
