Area Forecast Discussion
National Weather Service Tulsa OK
310 PM CDT Sat Jun 22 2019

.DISCUSSION...
Main forecast concerns continue to be the severe thunderstorm
and heavy rainfall/flooding potential through early Monday
morning. The existing Flash Flood Watch has been expanded
southeastward into southeast Oklahoma and western Arkansas.

Scattered thunderstorm continue to develop this afternoon across
parts of southeast and east central Oklahoma, as well as west
central Arkansas, within the 850 mb moisture maximum in response
to a mid level disturbance lifting northward out of Texas. These
are currently remaining in check intensity wise, but some
strengthening could occur through the rest of the afternoon given
how much instability - around 5 kJ/kg on mesoanalysis - is
present across the region. Additional development is still
expected later tonight along the approaching cold front to our
northwest that would first affect northeast Oklahoma during the
evening hours. Severe thunderstorms remain most likely to the
northwest of Tulsa this evening associated with the cold front
development, with large hail and damaging winds the main threats,
outside of the flooding potential. Precipitable water values
approaching 2 inches exist on current mesoanalysis, and this
should further increase given the strong southerly low level flow
that is expected to continue. These well above normal precipitable
water values will lead to very efficient rainfall production,
with the potential for very high rainfall rates areawide. Overall
coverage may wane some through the morning hours tomorrow, before
expanding again during the afternoon along the cold front as the
upper level trough moves into the central United States. Highest
concern severe weather and flooding wise should shift to areas
along and southeast of Interstate 44 tomorrow afternoon and into
the overnight, with a slightly higher risk of tornadoes than
exists today. That said, the main threats tomorrow will continue
to be large hail, damaging winds, and flooding.

Thunderstorm potential will shift southeastward Sunday night, with
much of the activity ending by midday Monday. Low thunderstorm
chances will exist mainly during the daytime for much of next
week, with temperatures within a couple of degrees of normal
values for this time of year.
