.DISCUSSION...
Main focus for today was taking a close look at dewpoints as we
reside in a very dry, post frontal airmass across the area.
Dewpoints are trending very low compared to guidance, and have
ensured this trend continues into the afternoon as mixing will
likely keep dewpoints low throughout the day, rising following
decoupling around sunset. This yields MinRH`s in the 20`s to
lower 30`s for the I-10/12 corridor north, but could see some
teens in interior coastal MS and SW MS at times later today.
Lowered dewpoints again from 17-23Z on Tuesday for the same
aforementioned reasonings, but will not be as dry today with
winds switching more from the SE as high pressure drifts east of
the area.
Fog potential does arrive back to the area Wednesday and Thursday
morning ahead of the next front. Will fine tune coverage/density
potential as we near closer.
Next light/moderate rain shower chances return Thursday, then
dries out late week into next weekend with warmer temperatures
