.DISCUSSION...High resolution atmospheric models now indicate
that the inversion Thursday morning will be stronger, and thus
mixing heights are likely to be limited to 1500 ft agl at best
during the afternoon. Light winds aloft do not appear strong
enough to mix the lowest levels atmosphere as well as models
predicated in previous days. Overall, the ridging pattern will
make for increasingly poor mixing as inversions strengthen through
this weekend.
