.SHORT TERM...Today through Thursday afternoon...A mid/upper level
ridge of high pressure will remain over the Rocky Mountains through
Thursday afternoon.  As such the forecast area will remain in a
southwest flow aloft in the short term. The mid levels of the
atmosphere will be too dry through tonight for the possibility of
showers. Wednesday afternoon/evening marginal instability will
combine with more mid level moisture for a slight chance of
afternoon and evening thunderstorms in Grant County and the
northeast mountains of Oregon. Similar conditions will occur on
Thursday for a slight chance of thunderstorms in the mountains of
northeast Oregon. It will be hot with highs temperatures today
through Thursday around 10-15 degrees above normal.  Polan

.LONG TERM...Thursday night through Monday. The pacific northwest
will be under a west to southwest flow aloft through the period.
Skies will be partly cloudy as moisture and instability will be
fairly limited. Precipitation will be isolated showers at times over
the cascades. Temperatures will be gradually cooling during the
period with highs back into the 80s for many locations. Surface
gradients favor locally breezy west winds at times mainly through
the gorge into the columbia basin.  94
