Southeast Alaska Forecast Discussion National Weather Service Juneau AK 506 AM AKDT Fri May 3 2024

SHORT TERM
/Through Friday night/ Short range forecast continues to be rather quiet as high pressure and light offshore flow persists across the area. Few if any clouds over the panhandle except a layer of high thin cirrus. The clear conditions have lead to some areas in the north dipping near freezing overnight so frost advisories remain up until 8 am this morning. Those same clearer conditions will lead to a sunny warm day today which will likely be the warmest day of the week. Highs are expected to reach into the 60s with the warmer air getting pushed into the panhandle from the south (850 mb temps rising to 2 to 4c) by the weakening low in the central gulf.

As for winds, inner channel winds have shown an upward trend overnight as northerly pressure gradients increased as the ridge over the panhandle was pushed into Canada. This was especially noticeable in the north where Lynn Canal, Stephens Passage, and Cross Sound are showing E to N winds of 15 to 20 kt this morning.
These winds should start to lower again this afternoon into tonight as the ridge rebuilds into the panhandle and slackens pressure gradients. Winds also remain elevated in the central gulf this morning (25 to 30 kt E winds) from the weakening low in the south central gulf. That low is not long for this world however as it is expected to weakens away by this afternoon weakening the winds in the gulf as it does so.

LONG TERM
Change in store for Southeast Alaska from the very beginning of this medium & long range forecast period. A weakening front crossing the Gulf will still produce some rain Saturday along the northeast Gulf Coast. South of Cape Fairweather, conditions should remain dry, if not sunny, through the daylight hours on Saturday, but a short wave will rejuvenate the distal end of the front as it approaches the southern outer coast late Saturday night and all locations should see at least a little measurable rain on Sunday. Unsettled weather and shower activity will remain over the region through the middle of the work week.
Looking well out into the long range, there are indications in long range guidance that at least part of the Panhandle may see some heavy rain Thursday and Thursday night. Deterministic and ensemble guidance are both picking up on this and it was a topic of discussion and coordination with WPC this morning.

Along with the increased cloudiness, there will be a subtle reduction in daytime highs during this extended range forecast.
Very little change to overnight lows until Wednesday night when they warm ever so slightly.

AVIATION

VFR conditions will continue through the TAF period. Off shore winds persist through today, with winds decreasing through the afternoon as a weakening surface low pressure dissipates within the north Pacific and upper level ridging builds in aloft. Clouds should be limited to FEW to SCT cirrus with isolated afternoon CU development over land.
