southeast alaska forecast discussion
national weather service juneau ak
252 pm akdt Sat jul 21 2018

Short term a strong ridge of high pressure will stay in place
over the eastern gulf, at least through the short term period. The
ridge will weaken and move over the panhandle late Sunday night
into Monday.

Minimal changes were needed to the overall pressure pattern, with
some nudging to the GFS and a little bit of ECMWF to account for
differences in Monday's pattern. Otherwise, mostly local effects.

Winds were increased primarily in the afternoon to account for sea
breeze and along cross sound CAPE decision with the tip jet along
the coast.

Pop's were updated using the NAM (although there isn't a lot of
pop to speak of). The next chance for precipitation comes on
Monday along the western boundary of the eastern gulf, then
quickly retreats. One of the main challenges for today was the
interaction between the sea breeze and the marine stratus.

Temperatures were edited locally, staying above maximum guidance.

Several locations may see near or exceeded record temperatures,
especially tomorrow and possibly Monday. Cooler temperatures were
moderated along the coast to account for the marine stratus
layer.

Still, as drier weather continues, fire weather will be concern
over the northern panhandle. Some of the glacial rivers will see
slight increases over the next few days with the warmer
temperatures. Models continue to be in good agreement, the
exception being in timing differences when the ridge starts to
break down.

Long term Monday to Saturday upper level sections of the
mid to long range forecast are in similar vein of what we have
been seeing the last few days. The upper level ridge over the
eastern gulf to just east of the panhandle by early Tuesday
morning the rebuilds back over the panhandle by Wednesday
afternoon.

The closed upper level low slides southeast over the bering and
into the western gulf southwest of kodiak island by Tuesday
afternoon. There looks to be a short wave spinning out of the low
and into the western side of the ridge that is trying to ridge
over or through the ridge. It is this feature that will try to
spread some light rain into the northern panhandle Wednesday or
so. With ridge rebuilding the chances of rain are pushed back to
the west.

The very warm pool of air over northwest canada is expected to
persist early next week early and the slowly receded some. 850 mb
temperatures in british columbia are expected to be in the mid to
upper teens. Surface temperatures over much of the inner channels
will be upper 60s to mid-upper 70s possible. Warmer temperatures
towards the start of the week. The coastal areas will likely have
cooler temperatures as the lower level clouds will likely
continue to play games with coastline, limiting the potential
warming.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
