MID MORNING AND AVIATION UPDATE
Issued and extended a dense fog advisory for Gustavus, as well as continued the marine weather statement. Not expecting this fog to last beyond the noon timeframe due to ongoing solar radiation both at Cape Spencer and near Hawk Inlet/Juneau area. Expecting to see some light thermal troughing which will pick up winds just enough to begin to mix out the fog layer at the surface.
AVIATION
/through 18z Wednesday/ For the northern panhandle terminals, current LIFR/IFR conditions with very low cigs and limited vsby will make way for much improved flight conditions later today and through most of the evening. By noon today, expect VFR across the northern panhandle as cigs lift in response to a shortwave ridge overhead. Another wave approaches via the northern coast near Yakutat overnight into Wednesday, which will bring another similarly degraded flight situation Wednesday morning, with IFR cigs and periods of LIFR possible for most sites.
Further south, continuing the mixture of VFR and LIFR/IFR flight conditions this morning as lingering showers move south to north. Improvement will be slower than the north, reaching into low-end VFR around 21-00z this afternoon. Anticipating a similar trend overnight across the southern panhandle terminals tonight, potential for LIFR/IFR flight conditions via low cigs and limited visbys redevelops by 12-15z Wednesday morning and continues through at least 18z Wednesday.
No significant wind concerns outside of daily seabreeze effects, around 10kts or less. No LLWS concerns through the TAF period.
