conditions return for Friday with breezy winds remaining into
Saturday before winds relax into Sunday. Temperatures will also remain
cooler Friday through the weekend with highs in/near the 50s and
morning lows in the upper 20s or 30s which may lead to some
frost/freeze concerns for any susceptible plants Friday through Sunday
