243 pm akdt Sun apr 22 2018

Short term widespread rain has been occurring throughout the
panhandle today. A gale force front is on track to reach the
eastern gulf by tonight and move over the panhandle early Monday
morning.

Overall, changes to the synoptic pattern were minimal. Wind
speeds were nudged using the namnest and some local effects as the
gradient tightens over the northern gulf. With the wave pattern
set up Monday night into Tuesday, another round of showers and
gusty winds are expected across the southern inner channels
spreading northward and along the southern outer coast.

A small diurnal range will exist for temperatures, due to the
increased rainfall. Maximum temperatures were decreased slightly
during the short term period. Minimum temperatures were mainly
left as is due to cloud cover. Temperature changes were made using
some gfs. Pop and QPF values were raised over the next several
days, also using a GFS blend. Rain could be heavy at times, but no
flooding impacts are expected at this time.

Model agreement has continually improved for the Sunday Monday
system, however, some differences still exist as to the exact
timing and details of the individual shortwaves.

Long term Tuesday through Sunday as of 10 pm Saturday
occluded front will be moving E out of the area early tue
morning. Another occluded front will move into the western gulf
tue afternoon, then reach the eastern gulf by early Wed morning.

Still some model differences later Wed into Thu on how fast this
front moves through the area. The front will be weakening as it
moves onshore. GFS was fastest moving it through, with ecmwf
slowest. Ended up using the 18z GFS to handle the system through
00z thu, then transitioned to wpc for 12z Thu onward. This made
for a smoother transition between the different sources. Further
out, models suggest more ridging will develop over the E gulf and
se ak for late week and the weekend, but they have been
inconsistent on smaller scale shortwaves that might affect the
area.

Looking like most of the rain and wind with the second front will
be over the NW half of the area Wed into early thu. It is
questionable whether any precip will get into the far SE part of
the area, so kept any pops there on the low side. Currently think
later Thu into Sat will be dry over the area with the ridging, but
model differences make it difficult to be confident in this.

There could be another system approaching the area from the sw
sun, which would increase the precip threat then.

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.
