Synopsis
Temperatures on Tuesday will likely reach the 90s. There will
be an increasing risk for thunderstorms... Especially Tuesday
evening and night. A cold front passage will moderate temperatures
back to near normal Wednesday, but will bring with it breezy
winds. Dry and seasonably warm conditions are expected for the end
of the work week.

Discussion
Tonight and Tuesday: the threat of thunderstorms will mainly
confine itself to the extreme northeast and southeast corners of
wa to include the northern and central id panhandle. This threat
will possibly continue into the evening as well. Elevated cape
ranging 1200-1700 j kg over the southeast corner of wa east and
northeast into the camas prairie will maintain a risk of
thunderstorms over that region overnight into the early morning
hours. There is also a limited chance that an isolated
thunderstorm will push north and northwest into the palouse but
confidence is low with this scenario. Elsewhere, a few showers
will drift across the columbia basin north across eastern wa.

Temperatures tomorrow will likely be the highest for the summer
with temperatures ranging well within the 90's with some readings
teasing the century mark in the columbia basin tomorrow afternoon.

Tuesday night and Wednesday morning: with the the exception of an
isolated shower across the region, Tuesday morning should be
relatively quiet. As the day progresses into the afternoon and
evening, its going to be another story as nature paints a very
different picture as an active weather event affects the cwa
through this forecast period. Model guidance concurrently projects
for Tuesday night a well organized negative tilt upper level
disturbance supporting a strong cold frontal boundary tracking
east and northeast through the inland northwest and then continues
into the northern id panhandle. Very warm daytime temperatures
and higher dewpoints will destabilize the regional environment
enough to support the development of scattered thunderstorms along
the local gusty winds, possibility of small hail and localized
downpours through the evening as this system pushes through the
region late Tuesday evening through the early morning hours
Wednesday. Aky
Wednesday: dry and gusty westerly flow will be in place Wednesday morning
behind Tuesday night's cold front passage. Winds will be
strongest in the morning and early afternoon but will slacken as
the afternoon wears on. We should see a good deal of sunshine as
the upper-levels dry out. Temperatures will be cooling 6-10
degrees from Tuesday with afternoon highs cooling back into the
70s to lower 80s.

Thursday through Sunday: high pressure will re-strengthen on Thursday
and Friday promoting another warming trend across the inland nw.

Afternoon highs will warm back into the 90s by Friday. We will see
less moisture arriving with this next warming trend and at this
time, do not anticipate any showers or thunderstorms. Shortwaves
swinging out of the gulf of alaska will begin to flatten the ridge
starting Saturday and into the weekend. A dry and breezy westerly
flow will redevelop which could elevate fire weather conditions.

Outside of this concern, it should be another pleasant weekend
with seasonal temperatures and dry weather. Sb

Aviation
18z tafs: showers embedded in the mid-level moisture plume continue
to move north and northeast across eastern wa and the id
panhandle. Some high-based thunderstorms are still expected to
develop and move near many of the TAF locations this afternoon but
it remains uncertain as to proximity and timing. Therefore, a
close weather watch will be maintained for the TAF sites in the
region covered with a vcts. The tafs will be updated as
thunderstorms move nearer to the airports. There is a chance for
some showers to develop near mwh-eat during the early morning
hours after midnight. Otherwise,VFR conditions will continue for
all TAF locations through the forecast period. Aky
