...MONDAY MAY 31 2021 8:30 PM EDT...

The south end of the upper trough that was offshore of the northwestern US a week ago is...as forecasted earlier in birdseye view post #6...becoming cut-off into a western Atlantic upper vortex located offshore of south Florida due to the strength of the current central and eastern US deep-layer ridge. The eastern divergence zone of the upper vortex is producing thunderstorms over Cuba...the western Bahamas...and adjacent waters. At the surface is the tail end of the cold front associated with the upper trough...with no current signs of an organized spin on ASCAT passes of surface wind.

As we kick off the official start of the Atlantic hurricane season in the next 24 hours...will be monitoring this area to see if an organized surface tropical feature emerges with the support of the upper vortex’s peripheral divergence. Currently none of the computer models shows this. If anything forms in the short-term...it would be guided more west toward the Florida peninsula as the surface layer of the eastern US deep-layer ridge is bridging with the Atlantic subtropical surface ridge. Anything that forms toward 72 hours will be guided more northwest toward the southeastern US coastline as the eastern US deep-layer ridge becomes eroded by the current western/central US upper trough.
