.DISCUSSION...A slow warmup to above normal temperatures is 
forecast through the weekend. Overall critical fire weather
concerns are low but there could be some localized areas on 
Friday across northwest Colorado as winds increase behind
a passing system. The southern mountains of Colorado will
see the best chance of wetting precipitation with this late
week system before mainly dry conditions return.
