Do not worry about the weather, region has 50+ cm of snow right now and more is coming, some melting during the day (espescially when it is sun-induced) and freezing overnight is doing only good. Recent over -20 degrees on the ground has accumulated a lot of cold in the ground, so, melting on the top ends with freezing below. That rain may clean some asphalt roads but non-salted local roads, narrow, with high snow-walls on the sides... only thing is that some of those snowpiles will be a bit icy and a bit more than usual number of bumpers are needed Ice surface can be a bit uneven also.

Well, and Karlstad, during most of the recent events, there was only ice they created with some watering, not much difference then :P

And about the predictability, it is between 5-25% for next week, so not very high :P But weather tends to repeat itself, this winter in this region has been snowy, and often on minus side with short warmer periods, keep it in your mind when looking how the forecasts are changing
