Discussion...
main changes to forecast through this afternoon was to increase
precip chances and quantitative precipitation forecast in the Idaho Panhandle and in the Cascades. A
batch of showers is moving through the region this morning. Much
of the steadier rainfall has occurred over the Idaho Panhandle into
extreme portions of eastern Washington. We are also seeing some showers
developing across the Cascade mtns. These showers have generally
been light across these areas with less than 0.05 inches so far.
Showers are expected to continue in the Cascade mtns and across
the northern mtns of Washington and Idaho through at least the early afternoon
hours. We will then see a little bit of a break around mid
afternoon with mainly some isolated to scattered shower activity
possible.

A slight chance of thunderstorms is possible during the afternoon
for the eastern half of the forecast area; however, the best
chances for thunderstorms will be this evening into tonight as a
wave currently moving into California this morning moves up
through the inland northwest. Convection is expected to Blossom
over or this afternoon and then begin to track into Washington this
evening. Best chances for thunderstorms will be across southeast
Washington into the central Idaho Panhandle. Some of these thunderstorms
may become strong this evening with gusty outflow winds and small
hail possible. /Svh

Aviation...
18z tafs: a low pressure system circulating off of southeast British Columbia
will continue to push moisture across the inland northwest. Much
of the showers through the early afternoon will be north of the
taf sites. However, the atmosphere will destabilize late this
afternoon with a redevelopment of showers and thunderstorms
into tonight. The strongest thunderstorms are expected to develop
over northeast or and track into southeast Washington and into the central
portions of the Idaho Panhandle. Gusty outflow winds and small hail
will be possible with these thunderstorms through the evening.
