In Portland, significant freezing rain accumulation, with locally up to 1 inch of freezing rain and sleet, caused widespread power outages and risky roads.
Freezing rain left roads, power lines and trees coated in ice in the Portland, Oregon, region, and by Saturday morning more than 270,000 people were without power.
A WINTER STORM WATCH has been issued for Harris County beginning Sunday afternoon through Monday afternoon.
According to reports from the National Weather Service, about 0.1 to 0.3 inches of ice accumulated across the Washington region Saturday, with the highest amounts concentrating along and east of I-95.
Wind chills will be very cold as well Sunday night into Monday with values as low as 10 degrees below zero in some places. Even if that storm fizzles out, there is a reasonable chance for measurable snow every day this week, which means that by the end of it - there will be plenty of fresh accumulation to account for.
TUESDAY: Temperatures will remain below freezing on Tuesday so any ice that accumulates will still be causing problems.
In addition, Lubbock and the South Plains is forecast to go nearly a whole week with temperatures below freezing, according to the latest forecast, issued Friday afternoon.
PGE outages as of 5 a.m. Saturday Feb. 13 2021
On top of this, roads/bridges will still be iced over on Tuesday morning so travel will remain almost impossible and quite risky. You can expect freezing rain that will transition to a sleet/snow mix and then eventually snow.
The winter precipitation will continue throughout the night and into Monday. Morning lows will be in the teens with wind chills in the single digits.
How long frozen precipitation and freezing temperatures last will depend on how quickly the precipitation arrives and how quickly the coastal storm forms.
