...CRITICAL FIRE WEATHER AREA FOR EASTERN AZ...FAR SOUTHEAST
UT/SOUTHWEST CO...MUCH OF NM...AND FAR WEST TX....

...Synopsis...
A shortwave trough will likely be moving through the base of an
upper trough extending from the upper Great Lakes to FL.
Northeastward track of this shortwave trough through the
mid-Atlantic and off the eastern seaboard will induce a more
eastward/northeastward progression of its parent upper trough.
Surface low associated with this system will begin the period over
the OH Valley before shifting northeastward into the Northeast.
Farther west, stacked low centered over southern Saskatchewan will
drift slowly eastward with an attendant moving southeastward across
the northern and central Plains. Lee trough is expected across the
High Plains, with eventual cyclogenesis anticipated across eastern
CO.

...Southwest...
Another dry and windy day is expected across much of the Southwest.
Deep boundary-layer mixing combined with a tightened surface
pressure gradient (resulting from a deepening lee trough) and
increased flow aloft (associated with the southward expansion of the
Canadian prairie upper low) will support sustained westerly surface
winds around 30-35 mph amidst single-digit RH values. Multiple
preceding dry and breezy days will likely have dried fuels enough to
support critical fire weather conditions across much of the region
and a critical fire weather area was delineated from eastern AZ
eastward across much of NM and into far west TX.
