...High Winds Across the Plains of Northeast Colorado Diminishing
This Evening...

.Strong westerly flow aloft across Colorado today has been 
producing strong winds from the mountains out across the plains 
this afternoon. Wind gusts have reached 55 to 70 mph at several 
locations this afternoon. The strong winds have caused rapid 
growth of fires on the plains, most notably a 10,000 acre fire in 
Logan and Phillips Counties. The strong winds are expected to 
continue through late this afternoon and then diminish after 
sunset.

Gusty winds are expected to develop again on Tuesday, especially 
over Weld, Morgan, Logan, Sedgwick and Phillips Counties. Damaging
winds will be possible in the Front Range foothills of Larimer
County.
