.DISCUSSION...
With a strong trough and cold front expected to move into the area
this weekend, cooler temperatures and multiple precipitation chances
are likely. With the trough gradually making its way into the
Rockies, Friday and Saturday will feature widespread precipitation
chances, keeping fire weather conditions at bay. Cooler temperatures
also arrive Saturday and Sunday, which will limit fire weather
concerns.
