confluent mid/upper level flow amid a relatively tight baroclinic
zone yielding some decent 850-600mb fgen this morning. parent
shortwave is relatively weak and the marginal instability is highly
elevated (above 600mb) with a lot of dry air in the 900-700mb layer.
this is resulting in a very narrow band of light snow with dry
conditions holding to the ne and sw. under this band, a quick inch
is likely with local amount perhaps up to 2 not out of the question.
main impacts will be along a line roughly south bend to portland
with dry conditions likely holding in our far ne and sw counties.
snow will exit by 16z with some pockets of sun possible by the
afternoon. some late day waa may push highs into the mid/upper 20s
west while eastern zones hold around 20f. light winds and mostly
clear skies will lead to one more night in the single digits for
our eastern zones before waa really cranks up on monday.
as has been discussed, significant pattern change for this week will
result in warmer (around normal) temps as western conus ridge
finally folds east. tue looks like our warmest day with highs
pushing 40f ahead of a weak/dry cold front that will drop us into
the low 30s for the rest of the week. will have to keep an eye on
fog/stratus potential given warm air over deep/cold snowpack but
surface dewpoints look to stay generally below 32f which will slow
the melt and limit fog potential. unsurprisingly, the latest nbm has
reduced pop`s below 10 percent for late tue/wed. the next chance of
precip isn`t until late thu into fri and even here chances currently
look pretty low, relying on a subtle shortwave intersecting a very
dry/stable airmass. better chances may arrive over the weekend as
some guidance members lift a trough out of the southwest conus into
our area but there`s still a lot of spread on this. overall, it
looks like a nice slow thaw this week with minimal flooding
concerns.

a small area of snow will exit ksbn over the next hour or so
based on nearby observations and fleeting radar returns.
meanwhile, at kfwa, this are of snow has just recently arrived
and will move through over the next couple of hours. beyond
this period of snow, vfr conditions are anticipated with wind
less then 10 knots. an easing subsidence inversion after sunset
may permit skies to clear out late; not a sure thing this time
of year when clouds like to stick around.
