Although temperatures have remained below freezing the past several days, you may have noticed some melting on the roads during the afternoons. We are nearly two months past winter solstice and the Sun has once again reached a sufficient angle to warm the roads, roofs and buildings to above freezing each afternoon no matter what the actually temperature is. This will help to slowly improve the icy road conditions, especially on secondary roads and city streets over the next couple of weeks.
But this melting also brings some problems. With road temperatures quickly dropping to below freezing as the sunsets, the water on the roads quickly turns to ice which rapidly changes the travel conditions each evening. Also, this frost freeze cycle each day will help create potholes as the melting water seeps into cracks in the roads, expanding on freeze up each night, which slowly breaks apart the roads. Our slow transition to spring is finally beginning.
