.SHORT TERM.../Through Wednesday as of 2pm Monday/ ASCAT shows
gale-force winds in the Northern Gulf from this afternoon. Winds
will ease once the front passes over the inside portion of the
Panhandle this evening. Below normal temperatures are expected on
the backside of this front. Southerly flow exists through the
short term, so a showery period remains with low amounts of total
rainfall. Expect higher amounts of precipitation at higher
elevations.

There is also some notable cooler air coming in behind the front.
850 mb temps drop down to 0 degC in this cooler air mass which
will have two effects on the panhandle. One will be a chance of
stronger showers with possible thunderstorms in the Gulf and along
the outer coast this afternoon and tonight. The second effect of
the cooler air is a drop in snow levels for Tuesday and beyond.
Snow levels will drop to 3,500 to 4,000 feet by Tuesday, thus the
higher mountain tops will likely see some snow at some point
Tuesday into Tuesday night. No snowfall anticipated at pass level.

.LONG TERM.../Wednesday through Monday as of 10 pm Sunday/
The long term period starts with weak ridging over the gulf moving
over the panhandle by Wednesday night as the next storm systems
enter the picture. Showers will continue on Wednesday with onshore
flow. After that, models are showing two surface lows entering
the gulf, one developing off Kodiak Island, the other piece of
energy developing in the south-central gulf. The 00z model runs
show some agreement that the lows will consolidate in the central
gulf and slide southeast. However, location and evolution of this
complex system is different amongst the deterministic models and
ensemble members. There is high confidence that the northern gulf
coast will get wet (think Yakutat to Cross Sound) - though not
excessively wet with 48-hour totals around 1.5 inches for
Wednesday and Thursday. As the system consolidates and shifts
southeast through Friday, model differences in location and
timing lead to uncertainty in the precip forecast for the area.
The best chances are over the gulf, along the coast, and the
southern half of the panhandle, but a broad brush of NBM was used
for PoP. Winds with this system look to be high-end small craft to
marginal gale over the outside waters.

After this system exits Saturday, a brief respite is expected
with some breaks in the clouds possible on Saturday. The break
will be short lived with onshore flow taking over and precip
returning to the panhandle on Sunday with the next wave. The next
impactful storms are on the horizon for the beginning of next
week, with hints of a cold, deep system affecting the forecast
area. Something to keep an eye on, as models are hinting at 850mb
temps across the northern half of the panhandle around -5C. This
could be the coldest air of the season so far.

Overall forecast confidence is average through Thursday and below
average after that.
