within the elevated area may approach critical wind/RH criteria,
though relatively cool temperatures should limit the threat to some
extent. See the previous discussion below for more details.

...Synopsis...
A broad mid-level ridge will take hold across much of the western
half of the country on Sunday in the wake of a fast-moving,
mid-level trough. At the surface, high pressure will be located
across the Great Basin, with a secondary high pressure center
located over southern Texas. In between, weak lee troughing will
begin to take hold across the High Plains.

...Southern Plains...
Southerly winds will increase in response to a tightening
surface-pressure gradient. Relative humidity will fall in the
upper-teens to near thirty percent during the afternoon. The result
will be elevated fire-weather conditions for a few hours during
Sunday afternoon. However, temperatures in the mid-50s to mid-60s
should mitigate a larger-scale fire-weather threat.
