Update...
afternoon storms in southwest Kansas are dissipating rather
quickly this evening. A few high resolution models keep
convection going in eastern Colorado this evening with
further development east overnight. Expect...main impact
from storms will be an increase in cloud cover in far northern
Oklahoma. A better chance for a few storms will come Sunday
afternoon/evening as a weak frontal boundary moves into
northern Oklahoma.

Discussion...
breezy and hot conditions continue for another day or two before
significant cool down and good chance of rain.

Models disagree somewhat on timing of initial surface boundary for
tomorrow into tomorrow night. Will go with slightly faster
NAM/European model (ecmwf) for initial frontal timing Sunday. This should bring a
few degrees of cooling to far northern Oklahoma for Sunday afternoon
and some low precipitation chances. This boundary will slip south toward
I-40/I-44 by Monday morning. Best rain chances remain across the
north until we get to the north of much stronger front makes its
way south into and through the area Monday night.

Tuesday highs are expected to be anywhere from 10 to 20 degrees
cooler with perhaps a few locations across the north remaining in
the 70s. This will be with only a slight chance of rain... but
abundant cloud cover. Best chances of rain occur late Tuesday
night into Wednesday as an mesoscale convective system likely develops to our northwest
and then slides southeast across OK and North Texas late Tuesday night
and continue to affect much of the area on Wednesday. This could lead to
some flood/flash flood potential and will need to be watched
closely. This will also make for a very cool day on Wednesday with
many locations remaining in the 70s. Temperatures in the 70s a distinct
possibility Thursday as well. Before warming trend commences
Friday. Chances of rain linger through the second half of the
week... with best chances across the south/southeast... closer to
surface boundary.
