Area forecast discussion, Sep 23, 7:45 PM AKDT, 8 hours 19 minutes before
Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
745 PM AKDT Thu Sep 23 2021
.UPDATE...As of early Thursday evening, 1 to 4 inches of rainfall
had fallen across the southern Panhandle since around midnight.
As the heart of an atmospheric river edges closer to the region
overnight before passing into Canada, we felt compelled to issue a
special weather statement describing sharp rises in rivers. A
quick perusal of ARIs do not indicate serious concerns, but the
EFI and its members graze the area overnight as some members
push standard deviations into concerning territory. While gusty
winds should ease somewhat this evening, breezy conditions will
persist overnight. Because of this and expected heavy rainfall,
there is a slight risk of mudslides Thursday night. But confidence
is too low to issue a flood watch and no real flooding is
expected. However, we will be watching observations overnight,
in particularly across the south.
Otherwise, the forecast is holding sound across the region as
rain blankets the region and winds blow through the Inner
Channels.

.PREV DISCUSSION......ISSUED AT ...251 PM AKDT Thu Sep 23 2021
SHORT TERM...A gale force low will continue to churn in the Gulf
Thursday night into Friday before eventually moving onshore to the
west of the region Friday afternoon into evening. As the
associated front passes through the panhandle many areas,
particularly to the south, will continue to see strong winds and
periods of moderate to heavy rainfall through the evening.
Observations from those areas have been indicating rainfall
amounts near or exceeding a quarter of an inch an hour. Expect
that winds and precip will begin to taper off through Friday into
Friday night before we have our next "lull" in the active weather
Saturday into Saturday night. Through the duration of the event,
some areas of the southern panhandle could see rainfall totals
around the 3-4 inch range. While we are currently expecting a
response on area streams and rivers, the precip should be spread
out over a long enough time frame to minimize flooding risks,
however will be monitoring the situation very closely. Instability
still looks sufficient enough to warrant the mention of
thunderstorm potential for offshore and coastal areas from around
Cape Suckling to near Cross sound this evening into tonight.
LONG TERM.../Saturday through Wednesday night/...The extended
period continues to be an active period for SE Alaska and the
surrounding waters as low pressure systems move through the Gulf
and into the panhandle. However, breaks will occur for some areas
and it is looking increasingly likely that there could be drier
weather, especially through Saturday and Sunday. Rain could return
for some locations by the end of Sunday, guidance continues to
show that a system may impact parts of the area. However,
ensembles have continued to indicate a preference towards a more
southerly track for this low. Should this verify, much of the
northern panhandle could be spared from much of the associated
weather as offshore flow helps filter in drier air from the
interior, cutting off a significant portion of the moisture
transport. The same cannot be said for southern areas however, and
should the current prognostic reasoning continue to hold, it will
be a wet start to the work week for many. After this system,
ensembles are hinting at yet another system arriving on Wednesday,
but growing run to run divergence means that giving details with
any degree of confidence is difficult. Alongside the active
weather, cooler air will continue to filter into the area at
various times, with 850 mb temperatures progged to be below -2C on
more than one occasion across much of the area.
