...CRITICAL FIRE WEATHER CONDITIONS EXPECTED THROUGH MONDAY...

.Warm, dry and very windy conditions during the afternoon and early evening hours today ahead of and behind a strong cold front will again produce critical wildfire conditions. The critical conditions will encompass most of the plains as well as the southern foothills so the Red Flag Warning has been expanded. Southwest winds ahead of the front will shift to the west/northwest and increase with gusts to around 45 mph as the front sweeps across the plains late in the afternoon. The shifting winds may produce erratic fire behavior and growth of any existing fires.

Strong and gusty northwest winds and low relative humidity on Monday may again produce high fire danger on the plains on Monday. As a result, a Fire Weather Watch has been expanded to include all of northeast Colorado.
