Wet now, rain forecast at 1am and 2-3celcius on minor untreated roads makes me too nervous. Would do it if dry or 4c.
I guess it depends what time your commute is, but if its raining at 1am and 2-3 degrees then its highly unlikely the roads will be icy at 7am for example.
Best think to do is check the ground conditions before you leave, that’s what I do.
Some days car windows can be icy but the roads are fine – Monday this week for example. I do tend to avoid riding when its icy after a big slide early this year resulting in various rips and tears to skin.
Regularly ride in below 0 in winter though and apart from a few dodgy patches where I expect ice then its generally okay.
