Area forecast discussion, Jun 12, 10:42 AM PDT, 2 hours 50 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
1042 AM PDT Tue Jun 12 2012

.SYNOPSIS...
A mild weather pattern is expected for the remainder of the week
into the weekend. Temperatures will be near average. The best
chance for showers and thunderstorms for the Inland Northwest will
be today into Wednesday as a frontal system moves from west to
east across the region. More scattered showers will be possible
near the Canadian border Thursday.

&&

.DISCUSSION...
The weak warm front has moved through the region with light
showers or sprinkles reported. This has helped raise dewpoints to
near 50, which will increase low level instability. Visible
satellite shows more clearing is seen in the wake of the front
across the lower Columbia Basin, and this is where the best chance
will develop. Afternoon CAPE values will range from 400-800 j/kg,
peaking near 00z. Shear from 0-6km looks best across southeast
Washington and the adjacent area of the Idaho panhandle which is
where storms if they develop, may become more organized. /rfox.

&&

.AVIATION...
18Z TAFS: Isolated showers from VFR cigs will continue through
early afternoon, but more convective development is expected after
21z with scattered showers with a chance of thunderstorms. The
best chance for late afternoon to early evening thunderstorms will
be across extreme eastern Washington and north Idaho, including
the KCOE, KPUW and KLWS with local MVFR cigs, small hail and gusty
winds near the storms. A cold front will move from the west,
clearing the showers and causing gusty winds from KEAT to KMWH
late this afternoon. The showers will gradually taper off
overnight at the TAF sites, but still linger overnight over the
mountains northeast Washington and north Idaho through Wednesday
morning. /rfox.
