North Atlantic Warm Hole Is Catalyst to Midwest Drought Development/East U.S. Cool Bias

The North Atlantic warm hole (NAWH) is the result of stratifying cold water in the Labrador Sea and south of Greenland caused by accelerated snow and ice melt from East Canada and Greenland during the past 10 years. This prominent SSTA feature has shifted westward during the late spring season, the farthest west shift during the 2013-23 active period.

Chilly Regimes Increasing a Freeze Risk to the Brazil Coffee-Growing Areas During Mid-Winter Not Tied to ENSO Since 1995  

Since 1995, chilly temperature regimes in or very near the Brazil coffee growing areas during mid-winter (July) have occurred in 11 years. The average temperature anomaly of the 11 analog years is coolest just west of the coffee growing areas.

U.S. May 2023 Wind Speeds Below Normal Due to -SOI

During May 2023 U.S. wind power generation was below normal on both zonal and meridional directional scales. Wind power generation areas across the Upper Midwest/Midwest U.S. and southwest Great Plains/Western Texas were each affected by the lighter than normal wind speed regimes. The macro-scale driver of the lighter wind speeds was an El Nino-like climate as defined by a vigorous negative phase of the southern oscillation index.

Midwest U.S. Continues to Dry Out

Soil moisture anomalies continue to trend drier across the Midwest U.S. Strong dryness extends from the central Great Plains to the Mid-Atlantic region. The GFS 15-day rainfall outlook maintains the dryness across most of the areas trending drier during May.
