Happy 2021! It’s good to have a winter weather event to talk about!
For Raleigh, it looks like the initial precip begins between 3 and 5am. Probably initial as rain, with a brief changeover to a sleet, rain, wet snow mix, which then changes over to all rain as we approach rush hour. Any wintry p-type in this first round should be of no consequence.
During the day, the rain will be spotty and light with temperatures hovering in the mid-30s. (a beautiful day!). Then tomorrow evening in the 7-9pm range snow showers will begin to break out in response to the cold upper-level low rotating thru. We’ll have a 3 to max 4 hour window til just after midnight of snow showers, some of which have the potential to be moderate. This is will be the time when Raleigh sees the potential for accumulating snow, in particular on grassy areas. Most likely, accumulations will be 1/2″ to 1.5″. Bust low would be snow in the air, none on the ground. Bust high would be 2-3″. Snow totals will not be uniform. They will be banded more like what you see with thunderstorm distributions in the summer.
Enjoy!
