normal under mostly sunny skies. Light northwest winds expected as
weak high pressure at the surface moves into the region. Warming trend
forecast on Friday as upper ridge briefly builds into Southern Plains
ahead of next storm system developing over the Desert Southwest.

Upper wave will move out of The Four Corners region Friday, lifting
northeast into the Central Plains on Saturday. In response, scattered
showers with a few isolated thunderstorms will spread into eastern
Oklahoma late Friday night into Saturday morning.

Initial wave will lift north Saturday night with a brief lull in
precipitation chances, although a few scattered showers will remain
possible. As stronger zonal flow aloft develops, secondary upper

showers/thunderstorms on Sunday as Pacific front stalls over the
area in advance of main cold front. Instability may be sufficient
for a few stronger thunderstorms late Sunday afternoon/evening. Still

heavier precip east by this time.

Cooler weather expected Mon/Tue of next week before temperatures
warm back to more seasonable levels by mid week as southerly winds
