Southeast Alaska Forecast Discussion National Weather Service Juneau AK 538 AM AKDT Mon Apr 19 2021

SHORT TERM. Warm weather continues through Monday, though some change is on the horizon. With the collapse of the northerly pressure gradient, the offshore winds responsible for pushing many areas of SE Alaska to impressive highs over the past few days will be much weaker. This will open the door for more sea- breeze dominated dynamics in many towns throughout the area which should help reduce the chances of temperatures reaching quite as warm as they have in previous days, though still expect 60s throughout much of the area. A weak front will attempt to break through the ridging responsible for the pleasant weather during Monday night. Dry air will weaken the front, but the moisture it brings will likely result in the formation of a marine layer. The marine stratus will impact the Gulf Coast and offer the possibility of drizzle through much of Tuesday. A shortwave will move along the northern fringe of the ridge, bringing some chances of rain to the northern panhandle and Icy Strait Corridor late Tuesday into Wednesday. Models are still differing in how strong the shortwave will be. However, given the strength of the ridge, do think that these chances of precipitation should remain fairly low.

Temperatures on the whole will begin to return to more seasonal levels through the first half of the week. As more of the area is exposed to the eastern flank of the ridge rather than the western, high temperatures will widely fall back into the 40s and 50s across the region. The marine layer will only augment this, with areas experiencing cloud cover also experiencing less thermal heating through the daytime hours. Low temperatures in areas devoid of cloud cover will continue to remain on the colder end, as a lack of cloud cover and residual snowpack combine to bring low temperatures back into the 30s and 40s. Confidence in the overall forecast pattern remains high, with lower confidence in the exact numbers for the highs and lows.

LONG TERM. / Wednesday through Monday / A large blocking ridge over the eastern Pacific extending into the Northwest portion of Alaska continues Wednesday and Thursday. Part of an upper level (500 mb) low south of the central Aleutians slides southeast. As it does the low aloft continues to dig the upper trough southeast of the west coast of the CONUS into Saturday. The upper level ridge repositions to extend from the north central pacific, through the gulf to the Alaskan interior and NW Canada for Sunday and Monday. The pattern Monday starts to look more chaotic as another low from the Bering moves into the western gulf.

With the blocking pattern in place aloft the forecast for SEAK is expected to be dry. There may be a possibility of rain around Friday night/early Saturday from a low in the gulf.

The drier pattern expected does not mean that it will be staying sunny. A marine layer is expected to have pushed into Southeast Alaska Tuesday night into early Wednesday. So the temperatures to be cooler, down to seasonal normals Highs in the 50s to 60s. The marine layer is expected to move off shore or be eroded by Thursday and late Thursday into weekend has the potential for sunshine again, however do not think the temps will push back to the warmth of the last couple days for SEAK.

Did not need to make much in way of changes to the forecast package. Forecast confidence is average to above average, as it tend to be under blocking patterns, when a more stable forecast pattern develops.
