.Discussion...
Strong northwesterly breezes will gradually slacken over the
course of today, and by tonight we will see a lower frequency of
gusts. Rain chances are near 20% today, but this isn't
necessarily representative of the whole day. The best chance for
rain will be in the Lower Keys during the morning hours as dry air
is still filtering in. By the afternoon, the chance of rain for
the entire island chain will be near zero. The dry air is really
noticeable in relative humidity values over the next day as
minimum RH values near 50% today will only be able to recover to
70% to 80% tonight. By Monday afternoon, we will approach critical
values as we briefly touch near 35% in the Upper Keys. Along the
Middle and Lower Keys, minimum RH values will be near 50%
