1045 PM EDT Thu Jul 9 2026
.SYNOPSIS...
Moderate to fresh breezes with occasional strong gusts are
expected to hold steady through at least Friday night as an
Atlantic ridge, draped across Central Florida, strengthens. Winds
will tend to peak in the evenings and lull slightly during the
day. Breezes are expected to ease back gradually through the
weekend. Shower and thunder chances will be slight or less over
the next few days, but trend sharply upwards late in the week as a
weak low level trough pushes westward across our area.
