Pressure Falls Attract Surface Winds

Looking at the early afternoon dewpoint values (the green numbers on
the current weather map)

there is a definite moist-dry boundary that
separates some western and northwestern Oklahoma counties from the rest
of the state.  This boundary represents the remnants of a weak cold
front that entered Oklahoma last night.

A quick look at the three-hour dew point change map

suggests that the
southern Oklahoma portion of the front continues to struggle eastward,
lowering dew points.  However, the northern part of the front is
retreating according to the dew point changes.

Why?  Probably because a surface trough is advancing from the panhandle,
as evidenced by strong pressure falls in the panhandle and extreme
northwestern Oklahoma:
