I've been running Hot routes from Phoenix -> El Paso -> Houston -> Phoenix. Just under HALF, yes, HALF of my legs driven have been LIGHT SNOW or similar, with a temperature of 18degrees.

In TEXAS? Obviously a bug, since such weather doesn't exist there. I mean, I could see a couple of legs as one thing, and just ignore it, but my max weather speed for 8 of the past 10 legs has been 45MPH, with the above conditions. PLEASE get this fixed.

I live in Texas and it does snow here.

Well, I'm getting more winter weather in texas than I was running to Churchill. It's still messed up. Please fix it.

It's not messed up. The game takes the weather that half of the route has and...d'oh, somebody else can explain it better than I can.

In any case, it's not a bug.
