...Synopsis...
An upper-level anticyclone will persist across the central and
southern U.S. while an upper low meanders along the West Coast
today. Strong mid-level flow will pivot around the periphery of the
upper-level anticyclone and overspread a dry boundary layer across
the Great Basin into the central Rockies and northern High Plains.
As such, dry or windy conditions should develop by mid to late
afternoon across much of the Intermountain West into portions of the
Plains states. However, Wyoming seems to be the best location where
longer term dry and windy conditions will overlap with receptive
fine fuels (i.e. grasses), warranting Elevated highlights.
