During 2026, marine heatwave (MHW) NEP25A persisted at record intensity off the Southwest Coast of North America. NEP25A is a significant contributor to the record warm U.S. thermal pattern for all of 2026 so far especially the Southwest States. Contributions to the anomalous warmth were also made during recent months by expansion of the Kuroshio MHW and the subtropical North Atlantic MHW.

The week 3-5 HDD projections are mixed but trending colder. Notable is the colder AI solutions. 3 of 5 late November East Pacific oscillation (EPO) forecasts are negative supporting potential for a “polar vortex” pattern to close the month. Additionally, negative arctic oscillation (-AO) is expected suggesting high latitude blocking. The potential for a chilly end to November is increasing.

Stratospheric warming develops during early November in parts of the polar region with varying response within the troposphere in the middle latitudes. The stratospheric warming event causes North Atlantic oscillation (NAO) to shift to moderate negative phase. The -NAO pattern will produce cold weather in Europe peaking next week.

Regional SSTA in South Atlantic Influencing Brazil Rainfalll
The SSTA regime in the South Atlantic is relevant to the prevailing rainfall pattern across Brazil. Currently, an intense marine heatwave is located in the eastern subtropics with attendant warming extending across the South Atlantic index zone which is a robust +1.28C. Meanwhile, a cool pool of SSTA rests off the Southeast Brazil coast.

Explaining The Natural Gas Price Rise
Generally, a cooler/colder 6-10-day forecast change across the high population/high heating demand East U.S. will cause natural gas prices to rise. Once a pattern change for a key region is agreed upon by forecast models during the 6-10-day period, the outlook is considered reliable and triggers a chain reaction across natural gas supply, demand, and storage levels.
