Discussion...
a cold upper trough will settle into the region tonight bringing
cold temperatures with lows mostly in the upper teens to mid 20s.
Drier air coming in behind the cold front passage earlier today
will continue to spread east from central and eastern Washington
into the Idaho Panhandle. Thus while a few snow showers linger
in the mountains of the Idaho Panhandle this evening expect activity
to continue to decrease. The Winter Weather Advisory was allowed
to expire at 7 PM. A few adjustments to sky cover were also made
based on latest satellite trends. Jw
