Southeast Alaska Forecast Discussion National Weather Service Juneau AK 232 PM AKST Fri Mar 5 2021

SHORT TERM. Satellite imagery this afternoon showing a weakening low off the Baranof island coast continuing to track to the north. As this low reaches the NE gulf becoming an open wave trough a second low, that has been tracking along the Aleutian chain, will swing to the SE as it moves into the AK Gulf. At this time the track of the low is expected to keep any impactful winds and precip south of the area as the low nears Haida Gwaii.

General southerly flow for the central and southern panhandle continues while to the north have winds shifting from the north to south this evening. Winds will once again shift from south to north as the gradient flips between the Haida Gwaii low and high pressure over the Yukon. In addition expect increased easterly outflow winds by Sunday. Gradient for now not depicting any strong outflow winds.

Temperatures, with the exception of Haines which stayed near freezing, reached the upper 30s to mid 40s with precip changing over the mostly rain. The track of the low would likely keep a limited diurnal change this evening, however possibility of clearing and radiational cooling may drop temps a few more degrees. Central and northern locations still expect to drop below freezing so likely see a mix precip later tonight with any lingering showers. As the weekend progresses the region moves into the drying trend. Haida Gwaii low moves some precip over the southern panhandle upwards of Frederick Sound but offshore flow will bring clearing skies for the north. Cold air advection and the clearing results in larger diurnal temp range for Saturday and Sunday, with temps to the north dropping to the teens and 20s while day time highs reach the mid to upper 40s. A high of 50 is not out of the question for areas with good downsloping.

Operational and ensembles models fell into much better alignment depicting these next systems. Uncertainty with respect to the diurnal temperature curve remains but overall no impactful weather expected.

LONG TERM . /Sunday through Friday night/ . An upper level trough as well as weak northerly outflow (around 25 kt in Lynn Canal) should help keep chances of precipitation low for Sunday and Monday, at least in the northern portion of the panhandle. This would allow for long breaks in the clouds and the potential for temperatures to follow a diurnal trend with some overnight dips in the low temperatures. The substantial breaks in clouds may cause morning fog to hamper early morning aviation or slow down driving.

From Tuesday into Wednesday, a weather front will push into the panhandle and bring widespread precipitation. The associated surface low may make it to Yakutat or may move north before reaching the panhandle, making timing and precipitation amounts lower confidence. Overnight temperatures across the panhandle will remain near freezing resulting in some precipitation staying as snow. Areas to watch for potential advisory level snow include Yakutat, Gustavus, Juneau, Haines, and Skagway, though models are still in disagreement and this will need to be fine-tuned through the weekend. As for winds, Gulf winds were increased to 20 to 30 kt especially in the Westerly flow post front. Some increases to 15 to 20 kt for inside channel winds were preformed as well though confidence on how strong and when they will occur is marginal.

Once the weather front moves through the panhandle by Wednesday, temperatures may drop slightly below normal before a potential weak atmospheric river brings in warm moisture by the end of the week.

The long term precipitation forecast was nudged to GFS/NAM for Sunday, and nudged to the GFS/NBM for the remainder of the week. This helped define the Tuesday front. Temperatures were slightly nudged to NBM/WPC. Overall confidence is above average for chances of precipitation and temperature, but below average on strength of the Tuesday front and track of the weak atmospheric river.
