AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
1055 PM PDT Thu May 16 2013

.SYNOPSIS...
A spring time progressive weather pattern will continue through
the weekend featuring seasonably mild conditions and occasional
weak storm systems bearing scattered showers and a few
thunderstorms. The next week will begin manly dry and mild...but
there is increasing confidence that a wet and cool period will
envelop the region by mid-week.

.DISCUSSION...
A quick update to bump up POPs a bit across the Waterville Plateau
to the Okanogan Valley and over into the East Slopes of the
Northern Cascades. Isolated to scattered showers continue to
develop across this area late this evening as a shortwave moving
onshore interacts with some upper level instability. Expect this
activity to continue through Friday morning. Showers will then
become more widespread late tomorrow morning into the afternoon as
the atmosphere destabilizes with daytime heating. /SVH

.AVIATION...
06Z TAFS: Mid to high level clouds will stream in over the region
tonight as another weak shortwave trough of low pressure pushes in
closer to the region from the southwest. Light rain showers will
continue through the night north and west of KMWH and KEAT. Patchy
fog is expected to develop across the mountain valleys north of
the Spokane/Coeur d`Alene area. This fog may develop right along
the Spokane River around sunrise, which may impact KSFF for an
hour or two with reduced vis possible. Showers will become more
widespread by tomorrow afternoon, especially over the higher
terrain. There is a small chance for a thunderstorm in the in the
vicinity of the Spokane and Coeur d`Alene taf sites tomorrow
afternoon, but confidence is low at this time. /SVH
