.DISCUSSION...
Today through Tuesday: Brisk westerly flow aloft will be over the
Inland NW today with bands of high clouds. It will be a quieter
dry day with lighter westerly winds. Temperatures should be
noticeably cooler or more seasonal for late June with highs in the
mid 70s to mid 80s. By tonight into Tuesday, the flow aloft
rebounds into a shortwave ridge. Low level winds back to the
south and east as while temperatures are expected to jump 6 to 10
degrees warmer. With daytime highs in the 80s to mid 90s on
Tuesday, elevated heatrisk will be found across the Columbia Basin
and the LC Valley./rfox.

Wednesday through Sunday: Frontal zones pivoting ahead of an upper
level area of low pressure sagging down from the northwest will
bring showery weather, including some thunderstorms Wednesday along
with gusty/breezy winds. The cold upper area of low pressure will
park within close proximity, if not directly overhead, Thursday and
the resulting iinstability will allow for unsettled weather in the
form of mostly afternoon and evening showers and thunderstorms along
with gusty/breezy conditions. The upper level low moves east and is
replaced with a cool and somewhat unstable northwest flow Friday
which allows for some showers to linger with less intensity and
persistence, and mainly near the British Columbia Border and allows
the cooling trend to bottom out. Shortwave ridging and associated
warmer southwest flow allows for a warming trend with a generally
dry Saturday, however the southwest flow eventually allows for
increasing potential for moisture and disturbances to approach from
the west that segues to a general trof moving through Sunday which
allows for a return to potentially more showery and unsettled
conditions along with breezy/gusty winds. /Pelatti
