.DISCUSSION...
Chances for showers and thunderstorms will decrease today and a
mostly dry cold front moves through on Wednesday. Min RH values
should generally remain in the 40-50 percent range north of
I-10/12 and closer to 50-60 percent further south through the
first half of the week, then fall behind the front as drier air
filters into the area Wednesday night and Thursday. The lowest RH
values late in the week will favor areas north of I-10/12 though
winds are not currently expected to be strong enough for
significant fire weather concerns.
