Valid 111200Z - 171200Z

A deepening upper-level trough will translate eastward across the
eastern U.S. through the weekend bringing widespread precipitation
to the Appalachians, the Carolinas and Mid Atlantic regions
mitigating fire weather concerns. Farther west, fire weather threat
increases for the weekend across much of the Desert Southwest
portions of the southern High Plains as an upper-level trough
traverses the Northern Rockies into the Dakotas. Another pronounced
trough and attendant cold front progresses into the eastern U.S. for
day 6/Monday and day 7/Tuesday while above normal temperatures build
across the West.

...Day 4/Saturday - Day 5/Sunday: Desert Southwest and adjacent High
Plains...
A broad area of increasing mid-level westerly flow south of an
upper-level trough moving through the Northern Rockies and Northern
Plains is expected across the Desert Southwest and portions of the
southern High Plains over the weekend (day 4/5). Daytime mixing
within a very dry boundary layer Saturday and Sunday will translate
to stronger west-southwest surface winds combined with widespread
relative humidity of 10 percent or less across the lower elevations
of the Desert Southwest. Near record heat across the region over the
weekend will aid in drying fuels preceding the synoptic wind event.
In addition, strong westerly flow aloft could also promote enhanced
downslope flow along the Colorado Front Range for day 5/Sunday.
Thus, 40 percent Critical probabilities continue for these regions.
