.PREV DISCUSSION... /ISSUED 308 AM CDT TUE MAY 31 2016/

DISCUSSION...
Early morning water vapor imagery detected an upper cyclone
across the northern Plains...with convection extending along a
weak front from MN into southwestern KS. Shower and thunderstorm
chances will increase today...especially during the afternoon...as
the aforementioned cold front makes slow progress east. Increasing
instability this afternoon will be supportive of a few strong
thunderstorms...although the overall weak bulk shear should
preclude organized severe weather. That said...still could see
sporadic severe thunderstorms...with large hail and damaging
winds being the main threat. Thunderstorm chances will remain on
the high end into Wednesday as the weak cold front and a mid-level
shear axis linger across the forecast area.

As a weak upper low ejected out of the southwestern states...with
associated shear axis is expected to shift a little farther south
by Thursday into Friday. The higher PoPs are expected across
southeast OK into western AR during this timeframe...with rain
chances trailing off by Saturday.

Northwesterly flow aloft is forecast to develop late this weekend
into early next week...with several days of drier weather along
with seasonal temperatures.
