...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF EASTERN CO...NORTHEAST
NM...EXTREME WESTERN PARTS OF THE TX AND OK PANHANDLES...
In the mid levels, a trough will amplify over the Western States,
which will be accompanied by a belt of strong flow spreading across
parts of the Southwest to the central and southern Plains. As the
stronger flow and associated large-scale ascent emerge over parts of
the central and southern Rockies, a surface trough will deepen
across parts of the adjacent High Plains.
...Front range of the CO/NM Rockies eastward across portions of the
central/southern High Plains...
Enhanced downslope winds extending off portions of the Rockies will
support warming/drying over the adjacent High Plains. Westerly to
west-southwesterly winds of 15-25 mph with higher gusts are forecast
to combine with RH of 10-20 percent in support of elevated to
critical fire-weather conditions.
Present indications are that overlap of critically strong winds
(speeds of 20-25 mph) and low RH (10-15 percent) will be most likely
across portions of eastern CO, northeast NM, and extreme western
parts of the TX and OK Panhandles. A Critical area is in effect for
Across the surrounding Elevated area, elevated to
borderline-critical fire-weather conditions will be possible.
However, critically strong winds are not forecast to combine with
critically low RH on any more than a brief/spotty basis.
