Southeast Alaska Forecast Discussion National Weather Service Juneau AK 536 AM AKDT Wed Apr 8 2020

SHORT TERM. The surface low is moving east-northeast over the northern Gulf of Alaska while slowly weakening. The low is expected to move onshore just south of Yakutat and then reform in northwest Canada. The associated front to move through the panhandle today was just offshore Yakutat early Wednesday morning. Heavy snow started falling before midnight at Yakutat and started every early Wednesday over northern Lynn Canal. Winter storm warnings presently in effect are still looking good at the moment.

Rain and snow is falling across the rest of the northern and central panhandle as expected. Visibilities to 3 miles or less in snow and or heavy rain and ceilings vary between 700 ft and 2500 ft for much of the panhandle are being reported for the start of Wednesday.

The atmospheric river which is supplying the moisture for the precipitation is expected to move southeast to exit the southern panhandle late Wednesday evening. The feature is quick moving so QPF values will be limited with 1 to 2 inches of rain possible. Should be some lingering showers over the central panhandle from flow about the low near Yakuatat late Wednesday into Thursday and then those showers will end as well with clearing from the development of the surface ridge over the western and central gulf into the southern central portion of the state. Continue to see decreasing clouds through Thursday night.

LONG TERM. /Friday through Wednesday/ . As of 10 PM Tuesday . Mid level blocking ridge that becomes established over the AK Gulf Thursday night into Friday expected to remain in place through at least the weekend and possibly into the start of next week. Still fair amount of model differences as they do not handle the timing of ridge break downs and impact of up stream waves well. Expect the panhandle to remain dry due to surface high over the gulf. Any waves for the weekend look to remain to the west of the region. Northerly and weak outflow winds expected to shift southerly Sunday into Sunday night. This flow pattern change will usher in warmer air mass to the region. 850 mb Temp standard deviation of +2-3 C for the weekend. Large diurnal temperature swings for the start of the long range due to relatively clear skies with additional day time heating and nocturnal radiational cooling with temps. Highs low 40s to possible low 50s with lows initially in the low 20s and possibly lower for higher elevations and far northern areas then warming into the upper 20s to mid 30s. Break down of the ridge possible Monday into Tuesday with next chance of precipitation moving into the Gulf followed by more active weather pattern. Kept with ensemble solutions for the long range with forecast confidence being low due to models having issues with timing of ridge break down.

AJK Watches/Warnings/Advisories. PUBLIC . Strong Wind from 10 AM this morning to 4 PM AKDT this afternoon for AKZ027. Strong Wind until 4 PM AKDT this afternoon for AKZ025. Strong Wind until 1 PM AKDT this afternoon for AKZ023. Winter Storm Warning until 4 PM AKDT this afternoon for AKZ018- 019. Winter Storm Warning until 10 AM AKDT this morning for AKZ017. MARINE . Gale Warning for PKZ036-041>043-051-052. Small Craft Advisory for PKZ011>013-021-022-031>035-053.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
