<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'>Much
of the early part of the week will dominated by a strong ridge aloft over most
of the Pacific Northwest as a cut-off low meanders over southern California.
Subsidence (Sinking air motion) will warm the air aloft and limit mixing
heights to low values. Monday will see generally marginal smoke dispersal
conditions. Winds should mostly be from the northwest or north-northwest. <o:p></o:p></span></p>

EXTENDED OUTLOOK (TUESDAY – THURSDAY)<o:p></o:p></span></p>
<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Courier New"'>The
ridge-to-the-north/cut-of-low-to-the-south pattern is usually a slow-to-change
pattern and little day-to-day variation is expected in weather through at least
Wednesday. Expect continued low mixing heights and marginal smoke dispersal
conditions. On Thursday the low over southern California moves east as does the
upper ridge to the north. This will allow southwesterly flow aloft to develop
over the eastern Pacific and the Pacific Northwest. A Pacific cold front will
ride this flow into western Oregon late in the day. The subsidence aloft
switches to rising air motion and maximum mixing heights should rise
dramatically on Thursday. <o:p></o:p></span></p>
