southeast alaska forecast discussion
national weather service juneau ak
524 am akst Mon feb 18 2019

Short term A trough of lower pressure with rain and snow for
the panhandle moving east over the panhandle through Monday
morning. This one should move east of the area by late afternoon.

The next weather front is right on the heels of the first one.

Clouds are spreading over the western half of the northeast gulf
coast zone this morning. The snow or mix of rain and snow should
increase through the afternoon and evening across the northeast
gulf coast and then the panhandle.

Temperatures along the coast are in the lower to mid 30s so the
precipitation is either a mix or rain, however, the potential this
afternoon for so heavier fall rates may drag snow back to the
surface around yakutat. Think that sitka may stay rain today and
tonight because of the warmer temperatures in the area. The
precipitation should be tapering off Tuesday night into early
Wednesday from the north to south.

The heavy snow warning remains in effect for the juneau area to
early Tuesday morning. Additional snow today and tonight should
be in the 4 to 10 inch range.

Local effect changes were the main wind adjustments for Monday
and Monday night. Tuesday the larger edit was a delay in the wind
shift to a northerly direction for the northern portion of the
panhandle as the low slides to the southeast.

Long term Wednesday through Monday as of 10 pm Sunday
longwave pattern will generally keep ridging over the nepac with
troffing over the n-central pac and the bering sea. However, there
will be a couple of strong shortwaves that will flatten the ridge
as they move through during late week. After fri, models suggest a
much stronger upper ridge will develop across the gulf into
interior ak, and it should last into early next week. Made mostly
small changes to most forecast parameters through the period.

Still looks like a break in the precip Wed into at least the first
half of Wed night. Models have decreased their spread on system
moving in for late week, but some timing differences remain. One
trend that could be used to adjust the forecast is even the faster
models were slower to bring in precip later Wed night into thu
than forecast was showing, so slowed precip onset some. Once this
system gets by the area, looks like a drier pattern will be the
rule by the weekend with a deep layer northerly flow expected.

Still some model differences on how much colder air may move in
over the weekend, but does seem like at least some cooling should
occur. Overall, forecast confidence is about average through the
period.

Aviation As the next band of weather moves in think that from
yakutat to the juneau area will likely see visibility and ceilings
lower to ifr or near it through the afternoon and evening.

Slightly better cloud heights. For the southern panhandle expect
the ceilings to lower to ifr levels as the first trough move
through the area this morning to early afternoon, and then should
improve to the 2000-3000 ft range by evening.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
