.AVIATION /12Z MONDAY THROUGH FRIDAY/...
Not a lot of change for the 12Z TAFS planned. Dense fog not as
widespread as it could be, as little clearing took place
overnight. Most locations have some low clouds and fog as of 530
AM, but widespread dense fog has been confined mainly to the
dense fog advisory area which includes AOO and JST. 

Still holding onto some clearing later this afternoon, as the
moisture is not real deep (00Z sounding just to our west), but 
rather mild air aloft may limit mixing, so potential exist for 
conditions to be slow to improve today.

Earlier discussion below.

Area of wet snow and light rain associated with a weak low
moving off the coast, is now pulling out of our area.

Main issue overnight into at least early Monday morning will
be low clouds with patchy dense fog. Expect fog to be most 
dense in areas that have a bit of clearing, given snow cover.
Overall expect a wide range of conditions both over space and
time.

Conditions should slowly improve after sunrise, but with cold 
air at low levels and inversion in place, improvement may be
limited with the high pressure building into the area.

Weak low pressure systems will bring some spotty precipitation
to the region at times throughout the week, mainly across
the north. Temperatures will be on the mild side, more like
mid March, so rain will be more likely than other types of
precipitation.

Outlook...

Tue...Patchy fog possible early, then mainly dry.

Wed...IFR -RA/cigs N, MVFR -RA/cigs elsewhere.

Thu...Dry early, then rain later in the day with
restrictions possible.

Fri...Rain lingers, restrictions possible.
