Review of PDSI and EDDI as U.S. is Drying Out!

U.S. drought concerns are increasing. The dry month of June combined with a lot of heat has caused Palmer Drought Severity Index (PDSI) to trend drier. Consequently, the rainfall needed to neutralize that dry soil moisture signature has increased DRAMATICALLY in late June. Off the chart (>15 in.) values appear in the NOAA/CPC analysis in Washington, California, Texas, Georgia and North Carolina.

Relentless La Nina-Style SOI and MEI Marches On!

The dramatic difference between warm SSTA in the East Indian/West Pacific Ocean(s) and the cooler regime in the Central/East Pacific Ocean renders a La Nina-like atmospheric climate pattern unlikely to change.

Dangerously Warm Northern Gulf of Mexico SST

The northern Gulf of Mexico SST pattern has warmed to 85-88F (29-31C) in June. Daily SSTA analysis reveals these values are 3-4C warmer than normal. During the recent (2016-21) North Atlantic basin active tropical cyclone period when seasonal tropical storm average has exceeded 19 (normal is near 14), tropical cyclones moving into the western or northern Gulf of Mexico across 87F/31C SST (Harvey, Michael, Laura, Delta and Ida) have transitioned into category-4 major hurricanes just-before making landfall.
