WEATHER DISCUSSION: The weekend began on a warm and quiet note. Temperatures ranged in the upper 70’s to upper 80’s today, with lows dipping down into the upper 40’s and lower 50’s. The wind also played nice and remained on the lighter side at 5 to 10 mph. High pressure and upper-level ridging will keep those temperatures warmer for the rest of the weekend and through Monday, but as the upper-level ridge begins to break down, the winds will begin to pick up.

Starting Sunday, expect the winds to be on the breezier side with gusts up to 20 to 40 mph at times, especially along the Hi-line and the Rocky Mountain Front. With the combination of the high winds and relative humidity down into the teens, Fire Weather Watches and Red Flag Warnings are in effect. Any existing or new fires that develop will likely spread rapidly and be difficult to contain. It is recommended that there is no outdoor burning at this time. In the graphic below, the pink indicates the Red Flag Warning, and the peach indicates the Fire Weather watch.
