.SHORT TERM...Tonight through Friday...High pressure will remain
over the region through Wednesday before it begins to flatten
Thursday and Friday due to an upper level trough moving into western
Canada. Conditions will remain hot and dry through Wednesday and
then begin to slightly cool Thursday and Friday as some cooler
marine air moves east of the Cascades. Will begin to see increasing
breezy winds along the east slopes of the Cascades late Wednesday
and then even more pronounced Thursday and Friday as the marine air
push becomes more established. The threat of convection due to some
marginal instability will continue to be minimal and confined to the
far eastern mountains Wednesday and Thursday.

between flat ridging across the Rockies to the upper Plains...and
