.SHORT TERM...
(Today)
Issued at 251 AM CDT Wed Jul 3 2024

A few light showers this morning across NE OK from earlier
decaying thunderstorm complex. An additional MCV is currently
moving into central Oklahoma. Some of this developing shower/
thunderstorm activity could potentially move into portions of
northeast Oklahoma later this morning.

Dangerous heat is again expected today over much of the area.
Generally used dew-points from yesterday as starting point for
this afternoon`s forecast. Heat index values are expected to climb
into the 105-110 degree range with locally higher indices where
the excessive heat warning is in effect.

Some potential that storms developing near Oklahoma/Kansas line
this afternoon, along approaching cold front, could keep heat
indices from reaching full potential. Went ahead and kept heat
advisory for now, but some of those counties could be cancelled
if storms develop a littler earlier than expected. A few these
storms could be strong to marginally severe with locally damaging
winds the main threat.

.LONG TERM...
(Tonight through Tuesday)
Issued at 251 AM CDT Wed Jul 3 2024

Cold front is forecast to stall near the I-44 corridor tonight
and will briefly lift back north into the day Thursday. Heat
indices will again be a concern and will go ahead and issue heat
advisory areawide. Majority of models, including several CAMS,
suggest scattered thunderstorms will develop along frontal
boundary by late afternoon with storms pushing across much of
northeast Oklahoma Thursday evening. Marginally severe hail and
damaging winds will be possible in the stronger storms. This
activity is expected to continue overnight as storms move through
the remainder of southeast Oklahoma/west-central Arkansas
overnight.

Finally a break on Friday from the relentless heat of late,
behind cold front, with highs generally in the upper 80s in most
areas. A few lingering showers/thunderstorms will be possible
across southeast Oklahoma/west-central Arkansas before shifting
south by Friday evening.

Both GFS/ECMWF are in general agreement with another upper level
trough digging into the central/northern Plains on Sunday. There is
some potential for a MCS to develop to the north, potentially
impacting portions of the area Sunday night. Better moisture
return/instability may end of being slightly west of the area, but
still eastern Oklahoma could get clipped by eastern edge of
complex during this time.

Temperatures are expected to remain near normal for the early part
of next week as broad upper trough remains across the central/eastern
CONUS with at least low precip chances.

.AVIATION...
(12Z TAFS)
Issued at 631 AM CDT Wed Jul 3 2024

Light rain showers continue to move northeastward across NE OK
this morning. A few lightning strikes are embedded in the rain as
well. These showers/storms may impact TUL, RVS, and BVO through
mid-late morning, but confidence isn`t high enough to include the
mention of rain/storms at this time. Slightly better storm
chances will come this afternoon, mainly impacting NE OK and NW AR
terminals, as a weak frontal boundary sags in to NE OK and
becomes stationary along/near the I-44 corridor. Kept Prob30
groups at BVO, TUL, RVS, ROG, XNA, and FYV from mid afternoon
through at least 00z this evening, perhaps lingering through
midnight for the NE OK terminals. Although VFR is expected to
prevail, heavier rain may cause lower ceilings and reduced
visibilities briefly. Otherwise and elsewhere, VFR will prevail
through the TAF period with light-moderate south to southwest
winds.
