.DISCUSSION...
Elevated fire weather concerns start to filter back into the region
starting today as drier air begins to move in. The terrain-induced
dry line will propagate eastward this afternoon, leading to drier
conditions along and east of the Laramie Range, as well as dry
conditions in western portions of the region. Afternoon minimum
humidity values will drop into the 15 to 25 percent range for most
locations, with portions of the Panhandle above 35%. Luckily, winds
will be relatively light today, limiting fire weather concerns. Dry
conditions will continue through much of the week as a drier pattern
remains in place. Elevated to near-critical fire concerns return for
Wednesday afternoon as minimum humidity values drop into the 15 to 20
percent range and winds begin to pick up west of the Laramie Range.
Elevated to near critical fire conditions anticipated Wednesday onwards.
