.Discussion...
Temperatures will be closer to normal today, thanks in part to an
easterly wave passing through the area today. This feature will
continue to support elevated rain and thunder chances for today,
especially this morning. As this feature exits to the west, winds
will be slackening through Saturday, and may result in winds
becoming light and variable at times. This will result in poor
dispersion indices. Expect afternoon min RH values to hold around
the mid 60 percentile and recover to near 90 percent overnight.
