A brief Premium update was recently posted detailing the snow threat early tomorrow with a weak Arctic front swinging through, and has been posted below. To sign up for our Premium service, please click here. Otherwise, the relevant parts of the forecast have been freely attached below:
A quick burst of snow moving through will bring anywhere from a coating to two inches of snow tomorrow morning. The latest RAP indicates widespread amounts of around an inch of snow, while the HRRR model is a little less impressed. Generally, snow looks to start further inland around 6/7 AM, getting steadier across the region by 8 AM, and beginning to move out of the region by 10 AM. It will be light throughout, with any heavier bursts only resulting in snowfall rates around half an inch per hour. Nothing heavy, and most areas not even seeing moderate rates. Instead, just a light burst of snow through the morning rush.
The result of all this is that the event should be fairly low impact. Roads may be briefly snow-covered by a light, powdery snow so it will be important to take it slow. However, as temperatures are far below freezing, and there is little liquid equivalent in the snow, roads will not be all that slushy. I thus don’t expect many widespread impacts, and instead just slippery patches on roads. So if traveling between 7 and 10 AM tomorrow, just keep an eye out for the light snow and take it slow if necessary. Certainly nothing we haven’t seen before this winter.
