BUTTE — We had a nice beginning to this first full work week of summer on Monday in southwest Montana with more sunshine than cloud cover and close to seasonable highs. Tonight we'll lose most of the clouds of the day, so it will be a little cooler Tuesday morning, but still comfortable. Lows will range from the lower 30s to the lower 40s. Tuesday will be a mostly sunny, pleasant and warmer day with light to moderate breezes. Highs will rise above average, ranging from the mid 70s to the lower 80s.
