Tricky situation, though. Rain washes away the salt, but if the ground remains cold enough, the rain freezes on the surface. So it's a question of when, where, how much to put down. Some places are predicting small drops in temperature to 31, 32, 33 overnight which could make some roads treacherous tomorrow morning. These types of storms (snow to mix to rain to mix to rain to snow) are a challenge not only for forecasters but for road crews.
