UPDATE

Increased the coverage of thunderstorms tonight to include Skagway and Haines this evening based off satellite and lightning trends with a complex of storms pushing southwest near Whitehorse. This complex is also bringing easterly showers from Juneau and the Icy Strait Corridor southward to northern Prince of Wales Island. Showers may bring gusty winds of 15 to 25 mph and heavy rainfall as they pass through.

Additionally, large fires in the Northwest Territory are sending lofted smoke southwest into the northern panhandle, based off of webcams and weather obs in the Yukon and northern British Columbia. Have added haze into the forecast late tonight through tomorrow for northern panhandle communities.

AVIATION.../Through 06z Sunday/

Easterly flow continues to bring MVFR conditions to much of the panhandle as showers move through, bringing lowered CIGs around 2000 to 3000 ft and restricted VIS of 2 to 4 SM with heavier showers. An enhanced area of showers is currently moving through Skagway and into Haines, lowering conditions as low as IFR at time. Thunderstorm potential remains low, as all lightning associated with this cell has remained on the BC side of the coastal range. VFR conditions will prevail between showers, though the northern panhandle is expected to hold on to MVFR CIGs overnight. These variable conditions will continue into tomorrow morning before more widespread VFR ceilings and visibilities are expected to take hold.

Chances are looking somewhat likely for a period of fog to develop overnight, specifically for the southern panhandle. The most likely location is over Petersburg. Any fog development can reduce CIGs to below 1000 ft and visibilities to below 2 SM. A marine layer off the northeastern gulf coast is also expected bring reduced CIGs to Yakutat overnight.
