218 pm akdt Tue jun 27 2017

Short term Tuesday night through Thursday night... A high
pressure system located across the central gulf will move inland
tonight. A low pressure system will move into the southwest gulf
by Wednesday night. A series of short waves will spiral around the
low pressure system advecting moisture across portions of the
panhandle this week. Chances for showers will increase across the
northern panhandle tonight. Mostly cloudy skies will prevail
across most of the region the next few days. Models remain in good
agreement today.

Small craft advisories will prevail across northern lynn canal
through this evening.

By Thursday models stay in good agreement with minor differences in
advancing the precip into the panhandle, with the NAM being slower
and more conservative to bringing it onshore than the others. Timing
of the healthy precip with the associated front is early Thursday
morning west of yakutat and then will spread southeast across most
of the panhandle through the day.

Temperatures will be a bit cooler on Thursday for the max
temperature as clouds will have returned to a substantial thick
overcast layer. On the flip side the Thursday night lows will
generally be a few degrees warmer, with less loss due to radiational
cooling.

Winds over land will stay generally ranging around 5 to 15 mph with
a southerly flow. Inside waters follow suit with winds around 10 kt
or less, with the exception of the north-south orientated waters
with 10 to 15 kt. The strongest winds will be on the outside waters
with 30 kt small crafts moving across the gulf and then falling
short of the outer coastline and diminishing.

Long term Friday through Tuesday... As of 1000 pm mon... An
upper level ridge located east of the southeastern alaska region
with an associated surface high pressure will remain over the
area, influencing conditions for Friday into Saturday. Deep layer
onshore flow and plenty of moisture will fuel a sustained cloud
low level deck. Multiple shortwave troughs will then progress east
out of the gulf, originating from a broad area of low pressure
located over the central gulf, impacting the region through this
weekend. Long range models are in general agreement for
accumulating amounts of precipitation through this weekend into
Monday. As the systems make their approach, timing of
precipitation will become clearer. Pops were analyzed using mainly
the GFS model ensemble and then trended more with wpc guidance.

Pressure and wind updates blended towards GFS through Friday, then
towards wpc through the remainder of the long range period.

Overall confidence is average.

Ajk watches warnings advisories
Public... None.

Marine... Small craft advisory for pkz012.

Small craft advisory due to seas for pkz051-052.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
