MJO shifts to the tropical North Atlantic next week. Supports tropical cyclone development.

During neutral ENSO, the Madden Julian oscillation (MJO) is normally active. During northern hemisphere summer, influence of the convection phase of the MJO causes an increase in wet monsoon moisture and tropical cyclone risk in neighboring longitudes. The ECMWF 14-day MJO forecast indicates anomalous convection in the tropical West Pacific (now) shifts eastward and across the tropical North Atlantic in 8-14 days.

Global Crop Areas Susceptible to Drought

The Americas are indicating their greatest exposure to drought in crop areas in the NOAA daily global soil moisture anomaly analysis. Areas at risk include Canadian and U.S. spring wheat, the northern U.S. corn-growing region and far southwest Great Plains wheat zone. In South America a major Brazilian drought is affecting their second corn crop, wheat and soybeans. There is limited exposure to drought risk (for now) across Eurasia and Australian dryness is away from crop areas.

Big Warm-up Equatorial Upper Ocean Heat

A dramatic warm-up in the upper ocean across the equatorial Pacific Ocean in April. Indicated is any support for La Nina 2020-21 is now gone. Somehow the Nino SSTA regions across the eastern equatorial Pacific Ocean are slightly cool to within the La Nina threshold off the northwest coast of South America.

U.S. Hail And High Wind Event

Scientists estimate the largest hailstone on record in Texas (over 6 in. across in diameter) occurred near Hondo, Texas last Wednesday night. Three hail storms struck that night in Norman, OK, Dallas, TX and San Antonio, TX. Widespread damaging hail was reported…2-3 in. diameter hail was common. $1B damage is projected across the Dallas Metroplex due to this event. A single massive hail storm in this region is not unusual in this region at this time of the year. However, three massive hail storms are unprecedented.
