.SYNOPSIS...
Scattered showers and breezy conditions will come to an end
tonight. High pressure will gradually build in through the weekend
and linger into the middle of next week. This will result in
generally dry weather with temperatures warming to above normal by
the weekend.

.DISCUSSION...
Update this evening to lower snow level grids and add some light
accumulations of snow above 5500 ft elevation along the Idaho-
Montana border. Webcams at Silver Mt show some light accumulationson
grassy areas and Mullan Pass ASOS reported light snow falling this
evening. Temperatures were also adjusted for some of the sheltered
valleys across the northeast. Winds have diminished and will
remain light overnight across the northeast. While some of the
valleys will see fog formation and will not drop below the
freezing mark, our cold spots, like Deer Park and Republic will
probably get very close. Thunderstorms ended shortly after sunset
and an area of scattered showers continues to slide off to the
southeast. They should exit the Lewis-Clark Valley shortly and
Camas Prairie in a couple of hours. expect clearing and
diminishing winds overnight with fog for the northeast valleys,
especially along lakes and waterways. /Kelch

.AVIATION...
00Z TAFS: An upper trough and associated cold pool aloft has
destabilized the atmosphere, allowing scattered showers and
isolated thunderstorms to develop across much of eastern WA and
north ID this afternoon that will persist until 02z. Some of the
strongest cells may produce occasional lightning and brief heavy
downpours. As the sun sets, skies should clear quickly with the
loss of afternoon heating. Clearing skies and diminishing winds
overnight may produce low status at KGEG/KSFF/KCOE and possibly
KPUW. Most likely to be affected is KCOE where greater amounts of
precip will provide a source of low level moisture. Any stratus
that develops will dissipate by 19Z. Winds may again become gusty
after 19Z Wednesday. /EK
