Discussion...
the dog days of Summer are upon US and the hot/humid conditions will
likely continue through at least early next week and possibly
longer. Upper high will continue to strengthen over the Gulf
Coast states over the next couple of days with high building into the
middle/lower Mississippi River valley this weekend into early next
week. High temperatures near the century mark are expected Friday-sun
across northeast Oklahoma with heat indices in the 100-105 degree
range each afternoon across much of eastern Oklahoma and the
Arkansas River valley. Gusty south/southwest winds will provide some
relief from the heat...but will also keep low temperatures above
normal...especially across northeast Oklahoma where winds will
likely remain up during the overnight hours.

A little more uncertainty with the forecast into the middle part
of next week as the GFS breaks down upper ridge much quicker
compared to the European model (ecmwf). Will keep low chance probability of precipitation Tuesday/Wednesday with
a blend on temperatures...leaning slightly more towards the warmer
European model (ecmwf) guidance.
