About 75% of the U.S. is in a dry-to-drought soil moisture condition as meteorological spring arrives. Combining the month of February during 2000, 2012, and 2025 yields a similar Palmer drought severity index (PDSI) regime to FEB-26.

A combination of zonal flow in the 1-5-day and 11-15-day period and titanic Southwest U.S. high pressure ridging in the 6-10-day period leaves the west and southwest Great Plains without rain and increasingly very warm in the latest ECM 15-day forecast. Texas to Oklahoma shift wetter in the 16-30-day period while the western Great Plains stay dry and very warm. U.S. hard red winter wheat becomes a hot spot for drought development.

12Z GFS MUCH COLDER East U.S. Days 11-15
Thematic of the 12Z GFS is maintain warmth in the West days 6-10 beneath a titanic upper-level high pressure ridge which extends north and northeastward in the 11-15-day period causing the Canadian polar vortex to dive southeastward toward the Northeast U.S. The 12Z GFS is loaded with arctic sir and the shifting polar vortex forces the big chill into the Northeast Corridor in the 11-15-day period.

South America Season 1-4 Ahead Climate Forecast
An El Nino climate is projected to develop during the second half of 2026 and continue into early 2027 across South America. The Climate Impact Company constructed analog (CIC-CA) climate forecasts for the next 4 seasons are based on the evolution of an El Nino climate plus influences on climate from the tropical South Atlantic SSTA regime and tendency for strong marine heatwaves off each coast.
