SHORT TERM. A large low centered near 50N/138W is slowly moving south southeast. The strung out frontal band has wrapped around the low and northward to the southern gulf and Dixon Entrance. There are some clouds further north of the central and northern panhandle that are shearing apart. Light intermittent precipitation is falling over the panhandle, but mostly it is dry under the cloudy skies. As the low slides further south, high pressure from the west move into the northern panhandle and into NW Canada.
The clouds will be receding southward through late afternoon and and evening over the northern panhandle, and this will allow for good overnight cooling that will lower temperatures in the mid to upper 20s. The southern panhandle may have a slightly warmer night with the clouds hanging on. A weak trough ahead of the ridge building int the NE Gulf/NW Canada with assistance from an upper trough is expected develop a band of clouds across the southern portion of the panhandle.This weak band will be moving slow south to the southern panhandle. Northerly outflow will also be starting up, even more cooling for the north so overnight lows into the teens to lower 20s.
With the clearing skies there is small chance that some patchy fog could develop Sunday night, however think it will be limited by the cooler temperatures.
LONG TERM. /Tuesday through Sunday/ . Before the upper level trough moves out on Tuesday, mostly clear skies are expected across the panhandle during the day. Guidance has slowed the next weather system and will make it into the panhandle by early Wednesday with widespread precipitation in the afternoon. Once this system moves south Thursday, it may be followed by a weak atmospheric river impacting the southern panhandle. Models are optimistic and show another chance for dry weather and clear skies on Saturday.
Models have slowed the start of precipitation from our next system to early Wednesday morning. Precipitation will start in Yakutat, become widespread in the afternoon, and then move south. Winds will pick up with this front, and small craft advisories can be anticipated along the outer coast and inner channels. Snow possibilities for midweek are uncertain and could range up to advisory totals in areas including and north of Angoon and Juneau. The southern portion of the panhandle is forecasted to receive additional precipitation from a weak atmospheric river late on Thursday, though there is uncertainty on if the track of this system will move further south.
The long term precipitation forecast is a blend of GFS/NAM for Tuesday, and nudged to the GFS for the remainder of the week. This adjusted the surface weather front timing and speed. Temperatures for Friday and Saturday were trended down based on MOS and plume guidance. Overall confidence is moderate for temperature changes, but below average on which locations will see the most precipitation through the week.
