Area Forecast Discussion
National Weather Service Tulsa OK
402 PM CDT Fri Jul 5 2019

.DISCUSSION...
Surface frontal boundary/outflow boundary from morning convection
across Kansas was entering into Northeast Oklahoma this afternoon.
Southerly winds pooling moisture ahead of this boundary had
allowed for continued redevelopment of convection along and behind
this boundary. Large amounts of instability also resided ahead of
the boundary for storms to interact with. However...with meager
mid level and steep low level lapse rates along with weak wind
shear values...the greatest threats from these storms should be
some gusty to locally strong wind gusts and periods of heavy
rainfall. Overall severe potentials should remain fairly limited.

The greater precip potential will be through the early evening
hours across Northeast Oklahoma into far Northwest Arkansas. This
evening...precip is expected to begin weakening with the loss of
daytime heating with the greater potentials maybe across far
Northwest Arkansas as the parent MCV exits off to the east and
southeast. Overnight...there may be a potential for additional
showers and thunderstorms to approach the CWA late tonight from
the northwest...though latest model indications are that this may
stay north and west of the CWA.

Shower and thunderstorm chances are forecast to remain possible
for much of the CWA through Monday in response to a surface
frontal boundary waffling back and forth over/near the region
along with any outflow boundaries setting up from previous
convection. At this time there still remains some uncertainty for
exact placement of precip and will thus continue with lower end
chance pops. Like with todays convection...gusty to strong wind
gusts along with periods of heavy rainfall will be possible within
the stronger storms. The surface boundary looks to finally retreat
northward as a warm front Monday with the dome of high pressure
currently over Texas forecast to begin expanding and retrograding
westward across the Plains to the Inter-Mountain West.

Also this weekend into the first part of next week...hot and humid
conditions are progged to continue across the CWA. Temperatures
near the seasonal average will remain possible Saturday/Sunday
before temps begin to warm further behind the lifting front and
expanding high pressure. By the middle part of next week highs in
the mid to upper 90s could be possible for parts of the CWA. These
conditions will aid in creating heat index values in the 100 to
105+ range this weekend through Tuesday. Heat headlines may be
needed each afternoon...depending on the precip coverage.

In the far extended forecast...as the ridge of high pressure sets
up west of the CWA...this could possibly allow for upper level
northwesterly flow to drop a cold front through the region. If
this verifies...additional precip chances could be possible as the
boundary moves through with temps more closer to seasonal average.
Something to maybe look towards with the increasing heat over the
next several days...
