.DISCUSSION...
Very limited to no sky cover made for excellent eclipse viewing
for much of the area. Interesting observations to note were a 2
degree temp drop at KTUL and the solar energy trace per mesonet
meteograms.

Despite a brief loss in afternoon heating...another warm day
continues across the area. Scattered afternoon convection remains
possible given the environment in place...so will likely use a pre
first period at zone issuance. Scattered storms may impact NE OK
again later tonight ahead of an approaching cold front...so will
keep pops mainly along and to the north of I-44 overnight.
Rain/thunder chances slowly slide south during the day in the
vicinity of the front...with highest rain chances staying along
and just south of the I-40 corridor Tuesday night. Locally heavy
rainfall will be possible given the moisture profile and a
slightly slower frontal movement. Rain chances will continue to
shift to south along with the boundary on Wednesday...while at the
same time atypically cool high pressure for this time of year
sinks south in to the southern plains. Dry weather will continue
through most of the work week...with rain and thunder chances
returning by the weekend as moisture increases while at the same
time an upper level weakness across Texas impacts the area. The
cooler guidance temperatures for most periods were generally
followed.
