The current weekly data actually looks like a La Nina - we'll see if it continues.
  2. The heat content of the upper 300m of 100-180W at the equator warmed to near average temperatures in July. Still colder than in 2017 which did become a La Nina late. But, the trend in 2017 was already sharply down by this down by point - not up. In 2017, you had across the board cooling in July. We've had across the board uninterrupted warming since May. https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/ocean/index/heat_content_index.txt YR MON 130E-80W 160E-80W 180W-100W 2017 4 0.34 0.28 0.06 2017 5 0.37 0.36 0.30 2017 6 0.21 0.22 0.22 2017 7 0.13 0.15 0.16 2017 8 -0.19 -0.21 -0.40 2020 4 -0.20 -0.24 -0.30 2020 5 -0.51 -0.70 -0.92 2020 6 -0.35 -0.54 -0.62 2020 7 -0.10 -0.22 -0.13
  3. Some very heavy rain moved through here recently. CFS and Canadian both have August warm/dry for the entire West. I'm a bit skeptical, but we'll see. I think there should be pretty powerful (for August) cold fronts by the end of the month.
  4. The monsoon has brought colder temperatures and near daily rain here as of late, but we remain below average in most spots for July rain. The CFS has trended NM/CO drier and warmer since a few days ago, but still has Arizona pretty wet for the month. Albuquerque actually had a lot of rain in June, so the June-July total here for rain will be pretty normal (near 2.0" is normal, and we're near that now). I'm actually a bit more optimistic for December now, we started July with top five warmth, but we're going to finish relatively near average for how warm the month started. As late as 7/15 or so the high here was about 97F, but it's going to finish right around where I had it, 93.5F or so for the month.
  5. Closer this week. Nino 4 continues to resist cooling meaningfully.

  6. I've been updating my sheets that compare solar tendencies to weather in Albuquerque. First look since 2015-16 data was in. - Snowfall frequency in March & April now looks like it may be significantly impacted by the sun, with two of the last four low solar years seeing snow in April in Albuquerque (way above average frequency for four years) and none of the last four Marches seeing snow (way below average frequency, especially with two El Ninos). Over the next 10 years, I think snow frequency for March & April will both become statistically significant between the high and low parts of the solar cycle here - both have p-values of around 0.05-0.10 if you do a difference in proportions test right now. - Cold winter highs in Albuquerque are still far more common with low solar activity. This held up to some extent in the last four years, with 2018-19 about 2F below the 30-year average (1991-2020), and 2019-20 about 0.5F below the 30 year average, with the winters also below (2018-19) and dead on average v. the past 100 year average highs. - Heavy snow months are much more likely in high solar winters, despite the tendency for low solar winters to be colder. The data now includes 89 years, up from 85 before, with a substantial growth in low solar years (32, +4). I waited until we had two more La Nina and two more El Ninos for the update too. Long term, the odds of very heavy precipitation in a high solar winter also seem to be nearing statistical significance relative to low solar winters. For snow, it looks like there is an extra 19 percentage point shot at getting 2", 3", 4", 5", or 6" of snow in a month with high solar activity, compared to low solar activity.
  7. For reference: Big time cooling from a warm MJJ in 2017 is not happening right now. Instead, there is a warming trend for May. This is consistent with the SW cooling off recently. When there are big drops in subsurface heat, we fry with almost no moisture. When there is a big warm up, it cools off and gets stormier - pretty much immediately. We were very hot here in Apr/May but have cooled off in June, and have trended much colder lately in July. January 2017 was also extremely wet.
  8. Hurricane warning for Texas! Putting a lot of moisture in the Rio Grande Valley is probably good for us to the West though.
  9. Rain, clouds and humidity really broke the heat here - lots of days in the 80s now. Dew points over 60 - which always feels super weird and humid here. Month is on target to be near the 93.5F forecast I had for Albuquerque in July. The CFS continues to trend to a wet/cold August for NM, CO, AZ, and UT - it's been a while since that has happened down here, so I'd love to see it.
  10. I don't see anything to force big changes in Nino 3.4 at the moment, for say 2-4 weeks. Everything is remarkably near average below the surface down to 200m in Nino 3.4

  12. Looks like the cold east / warm west should continue for a bit in the Nino zones. Not really a whole lot of intense warmth or cold in the Nino 3.4 zone. The Euro is still more on board with a cold Neutral than a La Nina too -
  13. I'm expecting a bit of a crap winter for much of the West this year, but not so much for temperatures. Mostly for consistent below average precipitation. A hot high July in NM is almost preceded by a pretty warm December for much of the West, but I think we'll cool off later in the winter. No measurable rain in Albuquerque this July means the odds of an active monsoon are already below 25% using historical precipitation data, and that disfavors heavy December snow/big snowstorms late December historically for NM & CO. I would like to see a huge August for precipitation down here - it is way overdue. If the Atlantic turns hyperactive for hurricanes that is pretty much always a bad sign for a cold Western winter too (1933, 2005, 2017) - something to watch.

But the subsurface was flipping colder in those years in July. It is still trending warmer at the moment. Still think a La Nina is possible, but it does have some headwinds going against it at the moment.
  15. Something to watch in the coming weeks - we've never had a La Nina in DJF, i.e. Nino 3.4 below 26.0C for that period - when the waters below the surface of 100-180W at the equator are warmer than average in August. The June reading for 100-180w below the surface was -0.6, but there has been a steady warming of the cool subsurface waters. I don't know that August is a lock to be below 0 at this point. https://www.cpc.ncep.noaa.gov/products/analysis_monitoring/ocean/index/heat_content_index.txt
