I hope most of you in the central/east part of Portland chose to skip work/school today!
That first band of freezing rain passed through the metro area before sunrise, but was light enough that most roads don’t appear to have been affected much. Don’t be fooled, check out radar…
Here come more showers and they look quite wet this time! They are sneaking in due to that ridiculous huge gap in the radar coverage off the Oregon Coast.
Except for the timing of the heavier rain speeding up, the rest of the forecast is still on track. Let’s check current temps:
I hope you enjoy my graphics talent… The yellow shows the areas that are at risk of widespread road icing BEFORE NOON. This is roughly the “blue area” I showed on-air last night and in the previous blog posting. This is going to quickly become an event centered on those areas that typically see cold outflow from the Gorge. I find it very interesting the top of Mt. Scott appears to be busting out of the cold air. This tells me the cold layer is VERY shallow and will mix out easily anywhere in Clackamas/Washington/Clark counties. I left Clark county in the “scary yellow box”, but even there after noon it should be warming above freezing.
- In the next two hours a light glazing of ice is still possible anywhere in the metro area still below freezing.
- But for a large part of the metro area (outside of yellow area above+most of Clark County), you will be “in the clear” after the noon hour.
- Ice Storm is still on for central to eastside of metro area…roads likely turn very icy the next few hours there.
- Loading of ice on trees/powerlines will become a big issue this evening and tonight east of I-5 in Multnomah County, especially east of I-205
