.PREV DISCUSSION... /issued 341 AM CDT Tue Aug 22 2017/

DISCUSSION...
Relatively cool and wet pattern returns to August.

A cold front is set to enter Oklahoma this afternoon, bringing
cooler temperatures and a round of showers and thunderstorms. Most
of the CAMS have convection starting along the I-40 corridor
during the afternoon, then progressing southward from there as the
front marches on. With PWATs of 2 inches or more and the
possibility of slow moving storms, due to poor upper support,
heavy rainfall will be a possibility. Showers and storms may
linger into Wednesday, mainly along the Red River. Localized flash
flooding will be a concern, but models are in disagreement as to
where the heaviest rainfall will occur.

A shortwave will make it`s way through on Friday, sparking
convection mainly across northwestern Oklahoma where some of the
higher moisture return will be. Chances continue and spread on
Saturday.

A lot of uncertainty exists after this point, due to the
possibility of a tropical system impacting the area. Right now,
most models keep this system just south and east of the CWA. For
now, left low POPs in Sunday and Monday.
