week, has moderated, with temperatures returning to near normal. Only brief
morning inversions are likely, with good ventilation conditions from late
morning through the afternoon. The flow aloft will be westerly with a couple
of upper-air disturbances possibly triggering a few showers, mainly over the
mountains. Northwest to northerly transport winds will increase in the
afternoon, as the surface thermal trough shifts from central Oregon into Idaho.<o:p></o:p></span></p>

showery weather. Snow levels will drop to near 5000 feet. Showers will likely
linger into Tuesday with a drier northerly flow aloft forecast by Tuesday
afternoon.<o:p></o:p></span></p>
