The Elevated fire weather area over the southern High Plains has
been extended eastward into most of Northwest Texas, as the latest
guidance suggests westerly/southwesterly sustained surface winds of
15-20 mph amidst RH values near 20%. Otherwise, only minor changes
were needed, with some contraction to the Elevated area over eastern
New Mexico where surface temperatures of less than 50F should temper
the large-scale fire weather threat. See previous discussion below
for more information.

An upper-level trough over the West will weaken on Tuesday as a
midlevel speed max ejects downstream across the Upper Mississippi
Valley. At the surface, a low pressure system will lift northeast
toward the Great Lakes with an associated cold front slowly
advancing southeastward over the plains.

Although the wind speeds aloft will be weakening compared to
previous days, sufficient flow will likely yield sustained afternoon
surface wind speeds approaching 20 mph through boundary layer mixing
processes. Downslope westerly flow will also support warming/drying
at the surface, resulting in afternoon RH values below 20% despite
relatively cool temperatures across the region (generally at or
below 60F). Overall, these meteorological conditions support
elevated fire weather conditions given the dry fuels across the
