…VERY COLD TEMPERATURES THIS WEEK…

Temperatures will remain well below normal for most of this week.
Overnight lows for most lower elevations will remain in the 20s
with a few locations dipping into the teens Tuesday and Wednesday
nights. Afternoon high temperatures will struggle to reach very
far beyond the lower 30s, if at all, Tuesday and Wednesday.

What does this mean…
With these very cold temperatures, frostbite and hypothermia will
occur much faster. Wind chills will be particularly low in the
western Columbia River Gorge and the east Portland metro where
east winds will make it feel especially cold Tuesday night into
Wednesday. If outdoors, remember to dress in layers and cover
exposed skin.

Take precautions to protect pets and livestock from the cold as
well.

Uncovered pipes will also be susceptible to freezing and
bursting.

A slow moderating temperature trend is expected to begin on
Thursday.

…VERY COLD TEMPERATURES THIS WEEK BEGINNING TONIGHT…

An arctic front is stalled across west central Washington as of
7 PM, Sunday December 26th. This front is expected to drift south
overnight and bring very cold temperatures across northwest
Oregon and far southwest Washington beginning tonight.

Tonight’s low temperatures across the inland valleys will reach
the upper teens to lower 20s around sunrise while coastal areas
will see a larger spread from the upper teens well inland to the
upper 20s closer to the ocean. Any residual liquid surface water
will freeze to result in icy conditions and potentially hazardous
travel conditions, especially where roads have remained untreated.
Additionally, even light snowfall on top of the ice will make
conditions worse.

For the rest of the week, temperatures will remain well below
normal. Overnight lows for most lower elevations will remain in
the 20s. Afternoon high temperatures will struggle to reach very
far beyond the lower 30s, if at all.

What does this mean…
With these very cold temperatures, frostbite and hypothermia will
occur much faster. If outdoors, remember to dress in layers and
cover exposed skin.

Take precautions to protect pets and livestock from the extreme
cold as well.

Uncovered pipes will also be susceptible to freezing and
bursting.
