southeast alaska forecast discussion
national weather service juneau ak
611 am akdt Fri aug 23 2019

Synopsis A gale force low in the central gulf will drift east
into the southeast gulf this afternoon and into the southern
panhandle early Sunday before dissipating. Low pressure develops
across the northern gulf tonight and persists through Sunday. A
ridge of high pressure builds over the central gulf tonight and
shifts east into the panhandle Sunday afternoon.

Short term A strong weather front for august spread a good 1 to
2 inches of rain over the south and a half to 1 inch over the
north during the last 24 hours. Strong wind gusts of 40 to 50 mph
were recorded in ketchikan, metlakatla, and tenakee springs with
other locations experiencing very breezy conditions. Meanwhile the
northern inner channels see very light winds, including juneau
and haines. The low has been stationary most of the night in the
central gulf. But a shortwave over the western gulf will not only
push it eastward into the southern panhandle by Saturday morning,
but also swing round to its east side and beneficially enhance
rainfall over the southern panhandle this afternoon and tonight.

Likewise, another short-wave rides east across the northern gulf
today and enhances rainfall for the north tonight. Rainfall
amounts for the next 24 hours should amount to 1 inch or less over
the north and 1 to 3 inches over the south.

Rain showers and relatively light southerly winds will dominate
the weather Saturday as the low washes out into canada and weak
ridging begins to dominate the area. Due to higher confidence of
such a wet weekend, we lowered high temperatures for both Saturday
into Sunday. Some fog was added Saturday night into Sunday
morning for portions of the inner channels.

Forecast confidence is generally good.

Long term Sunday through Friday night ... Very strong zonal
flow aloft with a 120 kt jet MAX south of the gulf at the start of
this long range forecast period will amplify early on as an upper
low and trough track east over the peninsula and into the gulf by
Monday morning. The induced upper ridge will cause the jet core to
shift north over the central panhandle by mid day Monday and the
upper trough will sweep through on Tuesday. The pattern aloft
remains progressive with another ridge over southeast alaska
Friday night into Saturday.

The pattern aloft will result in unsettled weather at the surface.

While the majority of the long range period will feature fairly
high probabilities of precipitation, Sunday night through Monday
night stand out. At this time, the upper low discussed above will
cross the panhandle from west to east. This low will have a lot of
mid level vorticity and omega. At the surface, models are in good
agreement on heavy precipitation over most of southeast alaska.

Model are not in good agreement on specific timing. Current long
range forecast reflects maximum rain rates Sunday night through
early Monday morning with heaviest amounts over the southern
panhandle. Confidence in heavy rain associated with this front is
above average. Confidence in specific timing is below average.

Watch for changes in timing in subsequent forecasts.

After this front and associated heavy rain, pop diminishes
somewhat but never drops below chance levels until Thursday night
and then only for the southern half of the panhandle. Warmer low
level air does move in from the south in the second half of the
week and daytime highs will creep back up to the high 60s or low
70s by the end of the next work week.

Aviation While ceilings, winds, and visibilities plague
aviation interests over the south and parts of the central
panhandle, the far north, too, is experiencing lower ceilings,
too, due to light winds and a very saturated air mass. These
sites may see modest improvement before falling again tonight.

Meanwhile, wind will weaken a bit over the south, but rain and
mist (and its associated ceilings visibility) will not. We
continued wind sheer over the south through tonight in some
spots.

Marine Gale force easterlies through zone 43 eases this morning
as the low begins to fill and move east. But small craft
advisories persist through tonight in the offshore waters.

Meanwhile, as the front lifts and weakens, small crafts for
clarence strait and frederick sound expire this morning. Cross
sound though carries a small craft through this evening.

Hydrology Rivers have are beginning to creep up across much of
the panhandle but all are expected to remain in their banks.

Ajk watches warnings advisories
Public... None.

Marine... Gale warning for pkz043.

Small craft advisory for pkz022-034-036-041-042-051>053.
