.DISCUSSION...
High temperatures should be similar to yesterday, with 100-103
degrees possible at Tulsa/Bartlesville/Fort Smith. Excessive heat
warnings remain in effect for heat index values reaching 110 or
more this afternoon.

Best chance for rain arrives by late Sunday afternoon and evening.
Front extends this morning along KS/NE border. Upper level short
wave trough noted in morning water vapor imagery will approach
from the northwest on the periphery of the upper ridge. The
surface boundary combined with the upper support will serve as a
focus for showers/thunderstorms to develop late tonight over
central portions of Kansas.

Convective outflow will then help push the effective surface
boundary south by Sunday over south central Kansas and eventually
northeast Oklahoma by late Sunday/Monday. Some areas on Sunday
night into early Monday morning could receive an inch or more of
rain, especially if convection sets up along a stalled boundary.
Rain chances continue into Monday, which will put a temporary end
to the current heat wave.
