5AM, Tuesday, February 13
The models have not flinched at all and say rain should change to snow around 7 AM across the area. The intensity of the snow would be the most challenging aspect of the morning commute as it would be like driving in a snow globe. Roads would deteriorate rapidly as they will quickly become slush covered. Reading reports from other stations, the transition to snow has begun out west and local surface and dew point temperatures are beginning to fall quickly so I will be radar watching the radar precipitation depiction to will the snow/rain line eastward. From the reports I’ve read, the transition is quick and the impact is immediate.
Just to give an idea of the potential problems this morning, here is a snapshot of a projected radar image at 7AM. If this is accurate, it’s going to be a stellar winter wonderland as these would be 1 – 2” per hour rates for several hours. Unfortunately our ratios won’t be 10:1 but that won’t change the intensity. Conditions improve by noon.
