Day 4-8 Convective Outlook
NWS Storm Prediction Center Norman OK
0341 AM CDT Thu Apr 18 2019

Valid 211200Z - 261200Z

Mature mid-latitude cyclone will move off the Northeast coast on
D4/Sunday with shortwave ridging expected in its wake across the
eastern CONUS. Farther west, medium-range guidance suggests broad
upper troughing will slowly move across the western CONUS and into
the Plains from D4/Sunday to D7/Wednesday. Preceding moisture return
will result in an environment favorable for thunderstorms across
portions of the central and southern Plains, particularly on
D5/Monday. Some severe thunderstorms are possible but the lack of
better moisture return and relatively modest flow aloft are expected
to temper the overall severe coverage and potential.
