...COLD WEATHER ADVISORY IN EFFECT FROM 7 PM THIS EVENING TO NOON
PST TUESDAY...
...EXTREME COLD WATCH REMAINS IN EFFECT FROM TUESDAY EVENING

.DISCUSSION...A broad area of high pressure across the region will
result in cold and dry conditions through the middle of the week.
The high pressure aloft will also result in a thermally induced
trough within the Willamette Valley. This will bring easterly
winds through the Columbia River Gorge resulting in gusts of
30-40 mph each day. Highest gusts are expected Wednesday
afternoon at this time. Overnight, temperatures will fall well
below freezing and likely into the mid to upper teens. Be aware
that the apparent ("feels like") temperature, as breezy winds will
make it feel much colder. Therefore, a Cold Weather Advisory has
been issued for tonight into Tuesday and an Extreme Cold Watch has
been issued for Tuesday night into Wednesday.
