Southeast Alaska Forecast Discussion National Weather Service Juneau AK 302 PM AKST Wed Feb 26 2020

SHORT TERM. A low in the northern Gulf of Alaska weakens in place. A trough is moving across the panhandle spreading rain through the area. Another wave will move over the southeast Gulf and into the southern half of the panhandle Thursday. The associated surface low will weaken to a wave over the northeast Gulf Thursday night. Over the northern panhandle, lower level temperatures are warming to the difficult stage tonight and slightly warmer on Thursday. I say difficult as it could be warm enough rain, but it may want to remain as snow. Higher elevations likely to remain snow. QPF values look to be about a third of an inch so White Pass could get about 3 to 4 more inches.

A building ridge Friday over the gulf will assist the ending of showers from the gulf and into the panhandle. The reprieve should be short lived as another front will approach from the west on Saturday night.

LONG TERM. /Through Tuesday/ . The month of March is on the doorstep, but will have to wait an extra day this year, thanks to this being a leap year. For the most part, Southeast AK will finish February on a rather quiet note, but active weather will likely return in March.

Upper trough within the N Pacific jet stream will dig across the southern gulf Friday. This southern push will likely keep a developing low pressure away from the panhandle as model consensus tracks the low south of Haida Gwaii Friday. A remnant surface low in the northern gulf will lose upper support and weaken while high pressure builds over the Yukon into Saturday morning. This should result in showers diminishing across the panhandle through Friday night. A northerly wind shift is also expected as an inverted trough develops over the panhandle by Friday evening. Light outflow winds will be possible overnight into Saturday morning.

Saturday, our extra day of February, will likely be rather pleasant. Upper ridge will quickly move eastward across the gulf, shifting over the panhandle Saturday evening. Some areas may see potential for fog Saturday morning, with light winds and moist snowpack, although colder temperatures may cause the fog to frost out. Many locations will see near normal temperatures as the sun makes a brief appearance . but then comes March.

The month of March comes from Mars, the Roman god of war. The weather during March can often be seen as a war between winter and spring. The split flow pattern will likely be in full force during the first part of March. The battle between the northern and southern streams will make for challenging forecasts next week. The next strong front will move eastward across the gulf late Saturday and approach the panhandle sometime Sunday. While there are still significant timing differences concerning this system, there is reasonable agreement in moderate precipitation spreading across Southeast Sunday, along with the potential threat of marine hazards. Again, the main challenge will be where the arctic boundary sets up (near the Icy Strait corridor) and how long the cold air holds at the surface (especially in the upper Lynn Canal area). Snow levels will likely remain low, especially over the northern panhandle.

After Sunday, model forecast spread and uncertainty increase significantly, but ensembles support an active pattern persisting through mid week. The Climate Prediction Center's latest 6 to 10 day forecast indicates a strong tilt towards a colder than normal and wetter than normal outlook for Monday through Friday next week. All of this indicates increased probability for snowfall, but where and when is still very uncertain. It is almost time for "March Madness" and meteorological basketball.

AJK Watches/Warnings/Advisories. PUBLIC . Strong Wind until 9 PM AKST this evening for AKZ019-025. Winter Storm Warning until 3 PM AKST this afternoon for AKZ019. Winter Storm Warning until 3 AM AKST Thursday for AKZ018. MARINE . Gale Warning for PKZ036-041. Small Craft Advisory for PKZ012-013-022-031>035-042-043-051>053.

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