The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

Area forecast discussion, Jun 23, 10:45 AM PDT, 3 hours 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
1045 AM PDT Sat Jun 23 2012

.SYNOPSIS...
Showers and thunderstorms are expected over the Pacific Northwest
and northern Rockies again today and tonight. Some of the
thunderstorms could be strong and capable of producing heavy rain
and gusty winds. Showers should be more scattered on Sunday and
Monday, and mainly limited to the mountainous areas of the Inland
Northwest. There is a good chance that Tuesday will be cool, rainy
and breezy as a vigorous low pressure system moves through the
region. A warming and drying trend is likely Wednesday through
Saturday.

&&

.DISCUSSION...
Update to the morning forecast. Showers/thunderstorms are
developing over the Panhandle and northeast WA in response to yet
another short wave rotating around the large offshore low. This
convection should be limited to east of a line from Omak to Walla
Walla this morning. Much of this elevated activity should rotate
northward into southern BC by this afternoon. Then the surface-
based convection will likely initiate in the same area this
afternoon. Models continue to point to this area as the best
potential for strong storms. SPC is placing the slight risk area
in northwest MT and ultimately all of the cloud cover may be the
main limiting factor for our area. Will continue to monitor this
as the day wears on. The high precipitable water values in this
area will lead to very heavy rain with these storms.  RJ

&&

.AVIATION...
18Z TAFS: Thunderstorms have developed across northeast Washington
this morning.  This activity should continue through 21Z before
gradually moving into southern BC.  More thunderstorms will develop
along the ID/MT border this afternoon.  Additional showers and
isolated thunderstorms will move into the area from Oregon this
afternoon and evening.  Brief MVFR/IFR conditions are possible with
these showers.  Abundant clouds tonight should prevent the formation
of widespread fog or stratus but localized IFR cig/vis is possible.
