Short term Bit of a change from yesterday and i'm sure glad
that the mid shift captured a 992 mb low center moving into dixon
entrance this evening. This track changed northward and required
more wind and precipitation for the southern areas of the
panhandle.

The upper level jet axis is aimed at the n. End of vancouver
island with SW flow aloft over the rest of our area. Biorka radar
shows the precipitation associated with the occluded front around
the surface gale center. Upped the wind forecasts for NW gales on
the back side of this front and 30 kt for clarence strait. We
also added low level wind shear (llws) to the aviation forecasts
out of the stikine for wrangell and also klawock and ketchikan.

Rainfall amounts with this one are heavy but short lived for no
hydro concerns. Showers tomorrow with westerlies and the gales
mentioned below are significant on Wed for the outside waters.

Long term Wednesday through Monday as of 10 pm Sunday the
long term starts out with a strong low in the western gulf
pushing a front into the panhandle on Wednesday. The low weakens
as it tracks east over the northern gulf Thursday then weakens
even further on Friday as it is pushed south and eastward into
canada by a large ridge of high pressure building into the gulf.

The ridge looks to remain in place through the weekend and into
the beginning of next week.

The most impactful weather this week is expected on Wednesday as
the front pushes into the panhandle. Not too many changes were
made to the existing forecast for this storm other than to
increase winds slightly over the gulf to 40-45 kts as the front
pushes through. Rainfall will overspread the panhandle throughout
the day and persist into Thursday. Heavy rain will be possible at
times, however ivt values are not overly impressive for this time
of year. Onshore flow will keep numerous showers around the
region through the day on Thursday as the low in the northern gulf
weakens and slowly moves east towards the northeast gulf coast.

Shower activity looks to diminish from north to south on Friday as
the low continues to weaken and high pressure building in
switches the flow around to the northwest.

Guidance continues to indicate the development of a much drier
weather pattern by the end of the week which could continue into
early next week. Models are in good agreement that a high pressure
system will dominate the eastern gulf and panhandle over the
weekend but still have some discrepancies on its strength, the
axis of the ridge, and how it will evolve during the beginning of
next week. Despite some model differences, confidence is
increasing in a dry weekend for much of the panhandle.

Temps throughout the long term will remain near to slightly above
normal so not anticipating precip type issues. Overall forecast
confidence in synoptic pattern remains about average.

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.
