442 am akst Tue nov 20 2018

Short term Our persistent front continues to stream deep
subtropical moisture northward and over the panhandle early this
morning. Heaviest rainfall currently over the NE gulf coast and
also over the southern panhandle. Several surface waves have
developed and are riding northward along the front. One such wave
is lifting into the southern panhandle this morning, enhancing
precipitation rates there. Winds have increased in association
with this wave and SCA winds will affect many of the N S oriented
channels through the morning hours as the wave passes.

Current forecast has the front pushing east of the panhandle by
late this afternoon, although with the amount of weak surface
wave action currently it would not be surprising if it slowed a
bit. Remnant vertically stacked low spinning under the main upper
trough in the northern gulf this morning will continue to provide
onshore flow through early Wednesday when it finally weakens.

Showers will be fairly widespread over the north behind the front
through tonight but become more scattered over the south.

Weak low will pass just south of SE ak on Wednesday and Wednesday
night more jet energy digs into the backside of the trough over
the gulf. The net effect of this will be the tendency for precip
to end over the northern interior panhandle as the low level flow
goes slightly offshore. Isolated to scattered showers will
continue over the south and along the gulf coast. Temps will
slowly cool through the short term, but snow levels will remain
high enough that only rain showers are expected near sea level.

Long term Thursday through Tuesday as of 10 pm Monday
models getting closer on handling of thu-fri system that should
mainly be over the far s. Have used the ECMWF to handle this
system as it looks better given upper level environment. Then, the
other main adjustment was for 12z Sat to 12z sun, showing a
stronger system moving N into the area.

There were some changes outside these time frames, mainly to warm
temps some from Sat onward. Did bump pops up some for the S thu
into Fri with system nearby that area, and dried out the N some.

Limited pops to likely for the weekend and beyond systems due to
some timing differences in the models, although wpc was close to
the ECMWF idea for the weekend system. There could be some snow
with initial precip starting early sat, but all except the far n
inner channels should be rain by the afternoon. Depending on low
track, could see several inches or more of snow over the far n
especially at higher elevations. Based on large scale pattern
evolution, a warmer and wetter forecast are realistic especially
from sat-tue. Freezing levels may end up above 3000 feet for a
while during this period.

Small craft advisory due to seas for pkz022-042-043-053.

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.
