The wetter pattern change begins to emerge in the 11-15-day period, has developed in the 16-20-day period, and expands in the 16-30-day period. The core of the heavier rain is unclear based on the latest CFS, ECM, and GC forecasts.

The effect of the Middle East War on energy supply and prices increases the value of U.S. cooling degree day projections for the 2026 warm season. Provided is a monthly discussion of expectations and charts for each NOAA/EIA region of the U.S.

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.
