.SYNOPSIS...
Expect active weather through the weekend. Rain and high mountain
snow will continue through Washington and north Idaho tonight,
before decreasing from the west and northwest Sunday. For some

the open wheat country of Washington and the Idaho Palouse. Mild,
dry conditions Monday and Tuesday will be interrupted by another
threat of precipitation and winds Wednesday, before drying out

Valley.

.AVIATION...

00Z TAFS: A warm front laying from KSEA to KPDT at 00Z will move
north tonight and stall roughly from KEAT to KCOE by 12Z before a
trailing cold front sweeps through the area from west to east
between 12Z at KEAT to 18Z at KLWS. This frontal complex is fed by
a deep and well directed Pacific moisture plume and will promote
widespread MVFR and local IFR ceilings and visibilities in RA at
most TAF sites through the cold front passage. TAF sites entering
the warm sector tonight will experience LLWS late tonight through
12Z-15Z Sunday. Very windy and gusty conditions are expected at
eastern TAF sites Sunday morning as the cold front passes.
Ceilings should quickly lift to VFR at TAF sites as the trailing
cold front passes through...with windy conditions continuing
through 00Z Monday. /MJF
