.DISCUSSION...A cold front will push through the region during the
day tomorrow, leading to periods of breezy winds through the
weekend along with a notable cooldown in temperatures. This front
is associated with a broad weather system that will inflict the
site with elevated winds through the next couple of days,
especially Saturday, where winds could occasionally gust over 30
mph. Despite the incoming cooler temperatures, RH recovery will be
poor to fair, as the air mass associated with this broad weather
system will be quite dry.
