...Synopsis...
A large-scale mid-level trough situated over the western U.S. will
feature several embedded disturbances rotating cyclonically through
the flow.  Farther east over the Upper Midwest, a speed max will
move into the Lake Superior vicinity during the day as a mid-level
low moves southeastward across western portions of Ontario.  Lastly,
a weakening mid-level low over the Gulf of Mexico will move
southeastward into the FL Straits.  A few weak thunderstorms are
possible over the FL peninsula in association with this disturbance.
