BILLINGS — The first of several waves began moving over Montana and Wyoming on Wednesday. Light snow showers will be possible from late this afternoon through the overnight and early Wednesday morning hours, mainly in the eastern thirds of Montana and Wyoming. We can expect increasing clouds Friday and Saturday as the next wave arrives, and we'll get a few rain and snow showers very early Saturday with more wind in the afternoon. A third small storm will arrive next Monday, and it will likely bring our best chance for rain and mountain snow. Highs will cool beginning Monday, but they'll stay warmer than average for early February.
