A cold front moved through last night around 9pm and thank goodness! While it won't deliver any appreciable moisture to Northern Colorado, the wind shift, cooler temperatures, increased humidity, and even some light drizzle all will help make today an altogether different day for fire fighting along the Front Range than what we saw with Saturday's explosive fire growth. Temperatures dropped into the 20s and 30s across Northeast Colorado Sunday morning, with relative humidity values from 90 to

A couple of notes in today's update, both related.

Still, instead of temperatures in the mid 80s or so, we'll see highs drop into the mid 70s for

We haven't had many cool days and we've obviously have lacked rain and snow this early season as well. That will change for many of us by late in the weekend and early next week. This system will be a trough scooting through Sunday and Monday which will drag a cold front strong enough to drop temperatures some 20 to 30 degrees from where they are this week.
