Southeast Alaska Forecast Discussion National Weather Service Juneau AK 631 AM AKDT Mon May 20 2024

SHORT TERM
/Through Tonight/...A continually weakening area of low pressure approaches the central Panhandle from the northwest while a ridge of high pressure builds in behind it through the period. Scattered showers from a combo of the weak low's influence and onshore-flow will continue to taper off to isolated distribution, and clouds generally decrease in coverage through the period. Winds will continue to progressively diminish to even more benign levels through the period as the pressure gradient continues to relax as the aforementioned low continues to weaken and the ridge builds. Some Small Craft seas are likely today along the Outer Coast and for the Outside Waters.

LONG TERM
/ Tuesday through Friday night / Active pattern set to continue for SE Alaska for the remainder of the week. Tuesday will see widespread clearing behind the system that brought wind and rain through Monday, with temperatures approaching 60 as a result of daytime heating and light winds.

The next system will move into the northern Gulf on Wednesday, with a weakening front making its way towards the panhandle Wednesday afternoon and slowly push inland through Thursday.
Precipitation from this system is expected to be light to moderate, with most rain coming Wednesday night into Thursday morning. As of this forecast, model guidance continues to show a diminishing trend in terms of winds along the front, with small craft winds of up to 25 kt likely only along the coast with the tightening gradient. Likewise not expecting any significant increase in wave heights in the Gulf with this system.

Heading towards the weekend, clearing skies and drier weather once more on Friday as another transitory ridge moves over the Panhandle bringing onshore flow and light winds for the inner channels.

AVIATION
Monday morning observation sites across the Panhandle are reporting a mix of VFR and MVFR, with a few under IFR CIGS and PAKT under LIFR. As we move through the afternoon MOS guidance continues to highlight improvement to VFR; however, dynamics associated with this low, along with instability in the lower boundary layer, will lead to some productive non-TS convective showers. Have gone pessimistic in TAFS across the Panhandle to capture periods of MVFR CIGS and VISBY from -SHRA but will see some VFR during Monday afternoon between -SHRA.

Monday night conditions diminish as low clouds moves along the coast. For areas north of Icy Strait, thinking MVFR if this layer is able to penetrate past Cross Sound, VFR if it remains west. For areas south of Icy Strait expect MVFR from CIGS and pockets of IFR, higher confidence as we move further south and east.
