font-family:"Courier New"'>The upper-level trough that brought widespread
showers to the region Wednesday and Thursday will shift eastward and stretch
from Montana to Nevada. A fairly weak upper-level ridge will build just
offshore with the flow aloft drying and turning northerly. That will finally
put an end to the long stretch of unseasonably wet weather. Some showers may
linger through the morning, mainly over the eastern mountains, with generally
clearing skies in the afternoon. Transport winds will turn mostly northerly.
Surface temperatures will recover some, from Thursday, but remain below
normal. High afternoon mixing heights should make for good daytime smoke
dispersal conditions. Clearing skies will allow temperatures and mixing
heights to quickly drop off in the evening, so residual smoke may settle near
the ground.<o:p></o:p></span></p>

<p class=MsoNormal style='margin-left:.5in'><span style='font-size:10.0pt;
font-family:"Courier New"'>An upper-level ridge will extend from southwestern
Oregon to northeastern Washington on Saturday. Winds aloft and at transport
level will turn north-northeasterly with continued drying and warming of the
air mass across the region. After a chilly start, with surface-based morning
temperature inversions, plenty of sunshine will help afternoon temperatures
recover to near normal. An offshore cold front is forecast to push the upper-level
ridge axis just east of the region by Sunday afternoon. Temperatures will warm
to slightly above normal with light northerly transport winds. The cold front
is forecast to sweep across the region Monday afternoon with a return to
onshore flow, cooler temperatures, and a slight chance of mainly mountain
showers or thunderstorms. Daytime heating should yield high afternoon mixing
heights during the outlook period.<o:p></o:p></span></p>
