It is getting cold isn't it?


At least six ‘rare’ waterspouts spotted across Chicago coastal waters (click here)



The National Weather Service is reporting at least six different “rare” waterspout spottings across the Chicago area lakeshore on Saturday.
Before this weekend, only 13 waterspouts had been reported across Chicagoland coastal waters, which runs north through Racine, since 2000. And of those 13, only 12 can be truly classified as similar waterspouts witnessed that day, the National Weather Service says.
As of Saturday evening, at least six different waterspouts were spotted and there is a possibly of more, which are waiting to be confirmed.
The following detail the times and locations for waterspout reports that were called into the National Weather Service Chicago and Milwaukee:
--Multiple reports which have not yet been confirmed at 2 E. Waukegan at 7 a.m.
--Confirmed report east of Lake Forest and southeast of the Great Lakes Naval Base in Waukegan at 10:10 a.m.
--Confirmed report of multiple waterspouts witnessed East of McKinley Marina near the east Milwaukee lakeshore about 10:14 a.m.
--Multiple confirmed reports three to four miles off the shore of the Chicago metro area at at 10:20 a.m.
--Confirmed report of periodic waterspouts reported East of the Hoan Bridge in Milwaukee at 10:28 a.m.
--Confirmed report north of Navy Pier at 12:09 p.m.
--Confirmed report southeast of Kenosha Harbor in Wisconsin at 3:15 p.m.


There was a blast of arctic air about two days ago that came down as a straight line front out of Canada.  Once it hit warm air it turned into this.

There is a Tropical Storm Ophelia in the Atlantic near the Virgin Islands.  It will go north and not approach the USA coast.

There is a Cat 4 Hurricane in the East Pacific that will remain in the ocean without traveling anywhere near the USA or Mexico.  It is Hurricane Hilary.


In the Hemispheric view below, TS Ophelia and Hilary are at approximately the same latitude.


Ophelia is at 18.40 and is rated a Tropical Depression right now and Hilary is at 17.40 and a Cat 2 now.

Both these storms were far more powerful and moving north.  Given their weakening trajectory it means they are losing water vapor access as they move north and further away from continental water vapor at the coastlines.  Continental water vapor happens at the shorelines of North America because of the interaction of air and land and the temperature differences that allow for the vaporization of water in wave turbulence/exposure.
