KEY MESSAGE 1: Dry and seasonable weather continues into the last week of October
The seasonably sensational stretch weather continues into the last week of October. This rain-free pattern is highlighted by sunny and warm afternoons with low humidity followed by clear and chilly moonlit nights with areas of frost and river valley fog. Afternoon dewpoints were adjusted lower into late week to capture the observed mixing trends that have occurred over the past few days. Minimum temps were also reduced by a few degrees to account for ideal nighttime radiational cooling.
Aviation
VFR flying continues to prevail with high pressure dominating the pattern. Areas of frost and valley fog could result in localized impacts through the weekend. LLWS will be possible across the eastern airfields late Wed night into Thu morning as winds just above the surface continue to blow out of the N and NE with the coastal low offshore.
