.SHORT TERM...Tonight through Tuesday. A weak disturbance will
pass to our north but some mid and high level clouds will drift
across the two state area this weekend. Meanwhile a ridge of high
pressure will influence the regions weather with dry conditions 
into the beginning of next week along with a warming trend 
expected. Afternoon temperatures should climb into the upper 80s 
tomorrow and then warm to around 90 or above into the middle of 
the week with 80s in the mountains. 

.LONG TERM...Tuesday night Through Saturday...Strong ridging across
the Four Corners region will weaken for mid/late week, allowing for 
weak troughs to cross the Pacific Northwest. With a mainly west to 
northwest trajectory, mainly dry conditions will prevail, with 
perhaps a couple of showers making it over the Cascade crest of
Washington Wednesday/Wednesday night. Periods of breezy conditions
will be possible Wednesday afternoon/evening and once again Friday 
afternoon/evening across the Cascade gaps with weak marine pushes. 
Temperatures 4-7 degrees above normal for midweek will gradually 
cool to near normal by Friday/Saturday.
