Southeast Alaska Forecast Discussion
National Weather Service Juneau AK
454 AM AKDT Sun Apr 14 2024

.SHORT TERM...

Pattern change on the way for southeast Alaska as rain and snow
showers will be diminish from north to south through tonight as
the surface low responsible for the days of precip moves inland
into British Columbia. Satellite imagery shows some patchy fog
developing across northern portions of the panhandle this morning,
but thankfully not seeing major reductions in visibilities at
this time. Could see another round of widespread fog development
over the rest of the panhandle tonight should the ground not dry
sufficiently under the approaching ridge. Marine winds will
diminish through today, with the potential for some sea breeze
impacts during the late morning or afternoon hours for some of the
inner channels. Increased winds within Glacier Bay and Lynn Canal
on Monday mid morning as north/south pressure gradient increases,
with northern Lynn Canal potentially reaching Small Craft
Advisory criteria.

By Monday afternoon, should be on the warming trend with high
temperatures reaching into the upper 40s to mid 50s under mostly
clear skies as ridging builds in overhead.


.LONG TERM...The major theme for this medium range forecast
period is one of drying weather and warming conditions. By next
Thursday, locations across Southeast Alaska will be experiencing
daily high temperatures from 5 to as much as 10 degrees above
normal for the middle of April. As is usually the case, more
southern locations will see the warmest weather with some spots
south of Frederick Sound getting up to 60 degrees or possibly even
higher.

Well before then, however, precipitation across the region will
have ended and cloud cover will have dissipated. Overnight lows
will still be below freezing at the start of the next work week as
a result of the clearing skies, so don`t put out those hanging
baskets of flowers just yet. Still, overnight lows will also rise
as the week goes by with most if not all locations near sea level
remaining above freezing by Wednesday night. Look for diurnal
temperature ranges of 20 degrees or more under these mostly clear
skies with that temperature spread remaining steady as both the
daily highs and overnight lows rise through the week.

.AVIATION...Southwesterly flow will continue through the day Sunday
with showers diminishing from north to south through the afternoon
hours. Heavier showers are possible along the outer coast as a
disturbance moves southeast in the gulf through the morning along
with some patchy fog for the northern inner channels. Skies will
be clearing from north to south with a ridge building in by
Monday.
