Area forecast discussion, Apr 19, 2:54 PM AKDT, 48 minutes before
Southeast Alaska Forecast Discussion National Weather Service Juneau AK 254 PM AKDT Mon Apr 19 2021 .SHORT TERM...Our period of sunny skies and record high temps is having its last hurrah today, even with some sea breezes limiting peak heating. A ridge of high pressure is expected build into the eastern gulf tonight from the south. This will cause flow to turn onshore. Clouds developing under the ridge, and those assoc with a weakening front over the central gulf, will be pushed onshore due to the changing flow. An upper level trough passing overhead from SW to NE around midnight will help to increase clouds further and cause some PVA/lift, leading to possible drizzle in places that have low clouds in place at the time. Have backed drizzle down to a chance based on how the high the clouds have been so far, but marine layers often form in place and therefore has lower confidence. The ridge will sharpen over the eastern gulf on Tuesday, causing winds to be more NWLY and along shore. This will help the marine layer clouds to back off some through the afternoon. Another upper level trough will track out of interior Alaska and across the Yukon Tuesday night. This looks to cause mainly clouds again, but have kept a slight chance or rain in the forecast tracking SE over the region through Wed morning. The trough has much colder air behind it (850mb temp of +5C today down to -4C across the north Wed AM), so it's possible that the precip will be more convective in nature. All models agree in clearing behind the trough from north to south through Wednesday afternoon along with a northerly pressure gradient setting up again. .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 continues to move southeast of the CONUS into Saturday. The upper level ridge repositions to extend from the north central pacific, through the gulf to Alaskan interior 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, or maybe some drizzle along the coast from the marine layer on Wednesday. Although conditions remain dry, sky cover may not remain as clear. A marine layer is expected to push into Southeast Alaska Tuesday night into early Wednesday. With this, temperatures are expected to be cooler. Seasonal normals include Highs in the 50s to 60s. The marine layer is expected to move offshore or be eroded by Thursday and late Thursday into weekend as the potential for sunshine returns. This being said don't think the temps will push back to the warmth of the last couple days for SEAK. Did not need to make much changes to the forecast package. Forecast confidence is average to above average as a more stable forecast pattern develops. && .AJK WATCHES/WARNINGS/ADVISORIES... PUBLIC...None.
