June 2017 meteorological images

That map of radar-estimated rainfall represents a deluge in early June which was a key to one of the month’s big weather stories, the erasure of all drought in Florida!

Another system in the Gulf of Mexico, which evolved from a big “CAG” (Central American Gyre), was at various times in its life somewhere on the tropical/subtropical/extratropical continuum, and officially Tropical Storm Cindy.

Gulf storms in June are common; what makes this circulation pattern below remarkable is the presence of a tropical storm in the southeast corner, Bret, unusually early in the hurricane season for a tropical cyclone from the eastern Atlantic.

As the month progressed, there continued to be tropical waves which were quite feisty for June.

Another swirl on GOES-16, this one non-tropical and led to everything from a windstorm in Utah to tornadoes from Wyoming to the upper Midwest. Also note the intricate detail in the atmosphere in the lower right part of the images.

And in regard to tornadoes, there was an outbreak of them near the end of the month.  The roiling rotating thunderstorms on GOES-16 one-minute rapid scan imagery:

And radar showed a string of supercells in Iowa.

The synoptic context of where early in the month an exceptionally photogenic tornado occurred in Alberta:

And from the satellite:

This was quite an outflow boundary in Kansas and Colorado!

This massive type of thunderstorm system appeared to meet the definition of an MCC (mesoscale convective complex).

And last but not least, check out these atmospheric waves!
