The birds who have been kept down by the northerly winds should burst
forth in a great movement the next several days. The high pressure area,
which is a ridge extending along the whole Appalachians is slowly moving
east, bringing a strong southerly flow.  The winds have now  (10 -11pm)
changed to the south and the sky is quite clear. The winds are currently
20- 30 mph in the central plains. This is shown on the current weather
map:

Right now there is strong radar reflection  through IL and IN and
becoming strong into western and central Ohio at the moment.
These URLS will give the picture at the time you view them and 1 hr

and set day for "Today" which will be Wed 4/16 UTC and the time for 0400
(= midnight our time) or later. Right now (11 EDT = 0300 UTC).
Click on "Contiguous US" at the top of the map, or, to view the regional
picture, "Regional reflectivity" on the menu on the left and then ILN in
Ohio on the map.

The NWS forecast has the air mass moving rather slowly such that this
strong southerly flow should continue until Thursday, maybe into Friday.
All this suggests a large movement.

The last couple days, a movement has been suggested from Texas up through
the Great Plains, now the movement will be up from the gulf. Eventually
the flow come up from FL, which is now rather quiet in the northerly
winds.
