.PREV DISCUSSION… /ISSUED 0107 AM CST Tue Feb 23 2021/

…Synopsis…
Broad cyclonic flow aloft will prevail across much of the CONUS
today, with an embedded mid-level trough pivoting around the
cyclonic flow and traversing the western CONUS while amplifying.
Surface cyclone development is expected to occur during the
afternoon across portions of the southern High Plains in response to
the approaching mid-level trough. Gradient winds and downslope flow
along the lee of the Rockies will contribute to dry and breezy
conditions across the southern High Plains. Widespread 10-20% RH
will likely overlap 20-25 mph sustained westerly surface winds for
multiple hours during the afternoon across much of eastern New
Mexico into western Texas, eastern Colorado and western Kansas.
While these surface meteorological conditions would typically
warrant widespread Elevated to Critical conditions, fuel
receptiveness to fire spread is not particularly robust, especially
across portions of the southern High Plains. As such, fire weather
highlights for widespread significant wildfire-spread potential have
not been delineated, though potential may exist for localized
grass-fire potential with patchy areas of drier fine fuels.
