Area Forecast Discussion
National Weather Service Spokane WA
1046 PM PDT FRI MAY 29 2015

.SYNOPSIS...
More thunderstorms have formed tonight and will linger in the
forecast area on into Saturday morning. Through the remainder of
the weekend the main threat of thunderstorms will be confined to a
small portion of southeast Washington and north central Idaho.
Meanwhile most locations will see very warm temperatures with
highs in the 80s. Thunderstorm chances will increase markedly on
Monday into Tuesday as a strong upper level trough moves in from
the south. Some of the storms on Monday could be strong and may
produce large hail and strong winds. Unsettled and cooler weather
will persist into the remainder of the work week with a threat of
showers and thunderstorms each day.

.DISCUSSION...
Minor additional updates to pops and weather in the grids but the
changes did not have a big impact on zone wording so no zone
update necessary. Forced elevated thunderstorms will remain
problematic in the forecast area tonight another weather
disturbance has worked its way into the forecast area via a
southwest to northeast route through Oregon. Expectation is these
thunderstorms will either move out of the area during the early
Saturday morning hours or erode when daytime heating disrupts the
elevated surface they are being lifted off (which may take as long
as 11 AM for occurrence). /Pelatti

.AVIATION...06Z TAFS: Another weather disturbance traveling
through the forecast area tonight 6-15Z is producing forced
elevated nocturnal showers and thunderstorms in the aviation area.
Daytime heating Saturday morning should allow for their
dissipation if they have not already exited the area which may
take as long as 18Z Saturday for it to occur. /Pelatti
