Cluster of strong to severe storms currently moving into portions
of northeast Oklahoma this morning. Ahead of storms, a zone of
moderate instability is present with MUCAPES in the 2000-3000 J/kg
range. Although flow aloft is somewhat marginal, expect a strong
to marginally severe convective cluster to move through portions
of east-central Oklahoma this morning. Damaging winds and brief
torrential rainfall will be likely in the stronger storms.
Depending on how quickly complex shifts east, high temperatures
may not be fully realized in some areas. For now, didn't change
high temperatures but this may be needed with later updates.

Upper ridge strengthens across the region Wednesday and remains
dominant through Thursday before weakening slightly on Friday. Hot
temperatures are expected area wide during this time frame. The
influence from the Tuesday night storms raising some uncertainty
on heat extent on Wednesday, otherwise the pattern is favorable
for widespread triple digit heat through Friday with record high
temps possible at a few locations. Expect a large portion of the
forecast area to receive heat related warnings or advisories for
this time frame.
A slow moving cold front moves into the region late Friday through
Saturday as the upper ridge loses influence. Temperatures will
cool to nearer seasonal normals along with an increasing chance of
showers and storms. The pattern through the weekend into early
next week appears to favor daily shower and storm chances with
temps continuing near early July normals.

A complex of storms may move into parts of NE OK after 03-04z,
so will carry a tempo group between 05z-07z at KBVO and a prob30
at KTUL and KRVS. Tempo groups will be included at the NW AR sites
between 07z-09z. Will leave out any thunder mention at KFSM as
complex looks to stay north of that site. Otherwise through the
period outside of thunder, VFR elements will prevail at all
sites.
