Some Will See Ice, Some Will See "Plain Rain"

Freezing rain forecasts are the worst. There is very little wiggle room for error. 1-2 degrees is the difference between wet trees or frozen trees. The difference between 0.10" of liquid and 0.40" of liquid can be the difference between having power and not having power. There is not much wiggle room in the forecast. With that said, here are my thoughts right now:

  • Winter Weather Advisory in effect for parts of Region 8.
    • This is NOT a Winter Storm Warning. An advisory is the lesser of 2 evils.
    • A WWA means that minor travel issues are possible.
  • The area that could see power issues is small.
    • First, because there is going to be a small area where the 32° and below air is in place and sufficient moisture.
    • Second, power companies have done A LOT of work to prevent power issues, including trimming trees along thousands of miles of line.
  • Most of us start as rain, and many will stay as a cold rain.
  • Minimal impact to travel until 10:00 PM or so.
  • Precipitation ends before sunrise.
  • Any frozen precipitation that falls will melt tomorrow.
First, here are the counties under a Winter Weather Advisory:
This lines up well with our current forecasts for freezing rain:
We are going to continue to update this forecast as new data arrives. I can't stress this enough, but make sure you have the Region 8 Weather App. We have the ability to pass along the latest data throughout the day and we will be posting video updates all day and night. Even late tonight, if you open the app, you will see the latest video update. We will have someone watching the weather all night.

Here are three models, showing three different outcomes for the freezing rain. As you can see, we don't have a great consensus among the models, but we do have a similar trend:


Stay with us through the day and night. We will give you the latest information and we will watch power outages closely.

Thanks, Ryan. Region 8 is spoiled in that we have an excellent team of meteorologists who are always looking out for us!

I agree. Nothing more important than his forecast when the weather looks bad...
