A new run of a shorter term model called the NAM is coming in COLDER than previous models... opening the door for the potential for Richmond to get significant amounts of ice (1/2") via freezing rain and sleet. If this happens, we would get power outages and icy ramps/bridges.
The black line on the map is the 32° line-- let's watch as it slides South and East early Sunday. Everything North and West of the gray line is BELOW freezing.
3am: Subfreezing air invades Richmond
9am: Temperatures below freezing. Sleet or freezing rain begins
1pm: Subfreezing air still in Richmond-- ice accumulating on bridges, power lines. Could be 1/2"
It's all about surface temperatures on this storm, and while some other models are showing temperatures rising above freezing quickly on Sunday morning, it's much more likely that warming will be painfully slow.
Still 72 hours to go on this one and much could change but it's looking icier as we get closer. We'll keep you up to date.
*Now is the time to make sure you are prepared for power outages and icy roads during the day Sunday*
