LONG TERM.../Friday through Sunday/
Mostly unchanged thought process for the extended forecast. Leading into the start of the weekend, temperatures will likely increase across the area. Highest temperatures will be located across the southern portions of the panhandle, especially near Hyder. On Friday, 850 mb temperatures indicate an increase to 12 to 14 C over POW, Ketchikan, and Annette, translating to mid to upper 70s during a well mixed, solar driven event. Slightly pulled back from max temperatures in Hyder, as 850 temperatures no longer are expected to get 850 temperatures both in the Hyder area and to the east. Hyder has a 70 to 80% chance of reaching a high temperatures in the 80s on friday with a 10% chance of hitting 90 degrees F.
AVIATION
CIGs of 300-800 ft through the early morning, before an improvement by midmorning from widespread IFR to MVFR. Sitka up to Cross Sound and into Icy Strait Corridor will see conditions dteriorate into the morning as the system pushes in, with MVFR CIGs expected across the area into Juneau.
MARINE
Inside waters: A front cleaning visible on satellite is sweeping across the outer waters, expecting to increase wind speeds for the inner waters by Wednesday morning. While wind speeds may increase to 15-20 knots in south to southeast facing channels, the highest impact will be the westerly wind shift occurring right around the noon timeframe for Cross and Frederick Sound. Areas exposed to the gulf are expected to shift somewhat quickly, with a more muted shift inland due to the front weakening as it moves over terrain.
Outside: A front moving eastward across the northern gulf will continue to the western coast, increasing winds up to 25 knots. Areas to the west of Icy Bay look likely to experience at least 30 knot winds with a chance of sustained gale force winds. A westerly shift behind the front still continues to be a concern. Wave heights are expected to stay mostly seasonal, up to 6 ft. Although different wave trains may result in confusing seas the the NE Gulf Coast.
