Latest Official Hourly Observation
Brief Weekend Review
Many just to our NW saw a significant ice storm. Some are still without power.
Tonight & Overnight / Tuesday Morning – Snow Day (or “opening 2 hours late” day)?
A wintry mix is likely tonight and into Tuesday morning.
It’ll begin as early as 6 p.m. (probably a few hours later) as rain, freezing rain, and sleet, gradually transitioning to snow overnight as colder temps arrive. Snow may accumulate: 1/2″ to 1″ is possible.
Temps tonight and Tuesday morning will be below freezing (9p 30 . 12a 29 . 3a 28 . 6a 27 . 9a 30 . Noon 36), so even a 1/2″ of snow will impact the morning commute. This certainly isn’t a big storm, but maybe you’ll get a snow day out of it.
Precip will end quickly in the morning.
A Winter Weather Advisory may be coming soon. The amounts in the below graphic may increase (as much as 1″ of snow in Davidson/Williamson) as the NWS fine tunes its forecast.
We’ll get an update on accumulations and timing this afternoon, and post them here.
Review of the Weather Models
HRRR – it’s a bit soon to say (the model only has a 15 hour range), but it looks like the wintry precip will arrive around 9 p.m. to 10 p.m.
RAP – agrees with HRRR timing. ETA 9 p.m. to 10 p.m. Here’s the RAP at 11 p.m.:
NAM (Hi-Res) - ETA 9 p.m. to 10 p.m. It’s pretty aggressive with the wintry precip. By 9 a.m. Tuesday, it says we’ll see about 1″ of snow:
Next Few Days
Another rainmaker arrives, but we think it’ll be mostly rain, with a slim chance of snow mixing in Saturday night. It’s way too far away to say anything certain for now.
