Area forecast discussion, Jun 30, 2:08 AM CDT, 3 hours 39 minutes before
Area Forecast Discussion
National Weather Service Tulsa OK
208 AM CDT Fri Jun 30 2017

.DISCUSSION...
Strong to severe MCS continues to push southeast through north-
central Oklahoma and southeast Kansas. This activity will likely
move into northeast Oklahoma before sunrise with the threat for
damaging winds/marginal hail. Overall severe threat should begin
to diminish east of highway 75 and especially southeast of I-44
as storms move into a more stable airmass with weakening wind
fields aloft.

Morning convection will likely produce an outflow boundary that
will provide the focus for additional strong to severe thunderstorms
this afternoon as atmosphere becomes moderately unstable with
surface heating. One or more thunderstorm clusters will likely
push south into southeast Oklahoma/west-central Arkansas tonight
with mainly a heavy rain threat, although a few marginally severe
storms could remain possible.

Frontal boundary stalls across southeast Oklahoma/west-central
Arkansas with additional shower/thunderstorm development along
stalled front Saturday and possibly into Saturday night although
precipitation coverage should be less.

Another weak upper wave will move into the Central Plains Monday
into Tuesday. Lingering precipitation chances will continue across
far northeast Oklahoma and northwest Arkansas, however main
thunderstorm activity is expected to remain north of area in
association with stronger forcing. Scattered showers/thunderstorms
will remain possible through the remainder of the work week as
another weak front stalls across the area.
