.SYNOPSIS...
A slow moving frontal system will pass through the region over
the next 24 hours. Rain against the Cascades this morning will
expand east through the day and into tonight. Rain in the Idaho
Panhandle will likely linger into Sunday morning. Mild and
unsettled weather is expected to continue into next week.

.DISCUSSION...
Plenty of rain is still in the forecast for today and tonight as a
frontal system moves through the region. The upper level warm
front is moving through the eastern zones late this morning and
early this afternoon for a chance of light rain in spots. From the
east slopes in to the deep basin there was a break in the action
as the surface front is moving through several hours behind the
upper level front. Expect precipitation to increase between
1100-1200 for these areas...before ending behind the cold front
passage later this afternoon.

Morning guidance is showing the front splitting as it moves
eastward this afternoon and evening. While light precipitation is
still expected across all of the eastern zones this afternoon and
this evening...pin-pointing just exactly where the best rain fall
will be is going to be tough. Current guidance does show a heavier
precipitation across the northeast mountains and across the
southeast zones. The Spokane-Couer D`Alene corridor should still
get measurable precipitation this afternoon and evening...just not
as much as previously expected. Umbrellas and rain coats will
still be needed through the evening hours. Updates to the zone
forecast were sent out. /Tobin

.AVIATION...
18Z TAFS: The well advertised warm front is wreaking havoc on
local TAf sites this morning. There was a break in the
precipitation at both KEAT/KLWS but as the cold front approaches
rain should begin again by or before noon. The frontal passage and
resultant down sloping winds will bring an end to the rain between
22-00z...however lingering low level moisture will result in fog
and stratus formation with IFR/LIFR afetr 06z. As such expect
another 24 hours of fluctutating conditions. A much tougher
forecast for the eastern TAF sites. Fog/stratus formed over night
and moved into KGEG/KSFF/KPUW. Conditions at both KSFF/KPUW have
improved as precipitation invades the area...unfortunately KGEG
may only see minor improvements at times. Behind the cold front
lingering low level moisture will again allow fog/stratus
formation at KGEG/KSFF/KCOE with conditions dropping to IFR/LIFR
afer 04z. KPUW will also see deteriorating conditions but not
until after 10z. /Tobin
