Southeast Alaska Forecast Discussion National Weather Service Juneau AK 545 AM AKST Wed Feb 24 2021

SHORT TERM. Our next weather system approaches the panhandle. Satellite imagery shows a surface low developing in the western Gulf with a long fetch of moisture being transport up from the Pacific. Aloft, a shortwave trough associated with the surface low pivots towards the panhandle. As this system continues to push east, widespread precipitation and winds will increase through the morning. Temperatures overnight have been steady in the low to mid 30s. This morning, most areas will be cool enough at the onset of precipitation to see some snow or at least a mix. As winds increase, a southerly push ahead of the low will warm temperatures enough for a change to rain. As the low deepens, winds pick up substantially bringing widepread strong wind headlines and high wind gusts up to 65 mph for the southern coastal areas. Further north, the transition to rain is still expected but exact timing could vary depending on when winds begin to increase. Newest model guidance suggest a bit slower arrival time with the low tracking towards Sitka before pivoting to the south and moving along the southern coast through late Wednesday night. This may cause current forecast arrival time to be a little on the fast side but small enough, forecast changes were forgone.

With this system, rain could be heavy at times across the central and southern panhandle. 24 hour precipitation totals nearing 1.50 inches are likely with lesser amounts to the north. As the low tracks further south Wednesday night, southerly winds will flip to the north and begin weakening. A change over to snow is expected as northerly flow allows for temperatures to cool. Areas across the north can expect to see the change over the quickest while the central panhandle sees a change over this evening and into tonight. Minor accumulations between 1 to 3 inches are expected with highest amounts across the far north. Thursday, a broad area of low pressure over the northeast gulf coast will promote shower activity across the panhandle. By Thursday evening, precipitation will exit allowing for a brief break on Friday.

LONG TERM. /Friday through Wednesday night/ . An active weather pattern continues into the long term with at least two systems expected to impact Southeast Alaska through early next week.

The period begins with weak ridging building over the Gulf on Friday leading to WNW flow over Southeast Alaska. Showers will be diminishing in the morning becoming mainly dry for most of the area by the afternoon. Drier air moving in aloft should even lead to breaks in the clouds during the day. Unfortunately, the quiet weather won't last long as the next weather maker moves by Saturday morning.

Precipitation moves back into the region as a low moves into the NW gulf swinging a front into the Panhandle Saturday morning. Good upper level dynamics will be associated with this front as a SW-NE oriented jet pumps in subtropical moisture. The NAEFs and EC Situational Awareness Tables already show IVT values and PW 2 to 3 standard deviations above normal for this time period. There is potential for heavy rain across the region this weekend as there are signals an atmospheric river will develop with this front. P-type should be predominantly rain with the northerly track of the low and persistent southerly flow into the Panhandle; however precip may begin initially as snow before low level cold air is scoured out. Snow levels will rise significantly as this system pushes in with levels as high as 3,000 - 4000 ft across the central and southern Panhandle on Saturday. Current thinking is that a total of 1 - 2.5 inches of liquid will fall from Saturday morning through Sunday evening. A brief break in the heavier precipitation is expected Sunday night through Monday as the system departs and a zonal onshore flow pattern sets up.

Models and ensembles continue the active weather pattern into early next week as there is good agreement another system will move into the northern gulf by Tuesday. This system may be very similar to the previous one with good upper level dynamics and subtropical connections. Details regarding these systems will be fine tuned in the coming days. Overall confidence remains high in an active pattern continuing across the region. Focused on the weekend system for any changes to the forecast.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
