...CRITICAL FIRE WEATHER AREA FOR NORTHEAST NEW MEXICO AND ADJACENT
PORTIONS OF SOUTH-CENTRAL COLORADO...

...Synopsis...
A short-wave trough moving northward to the east of a closed low
across the Great Basin will increase tropospheric flow across much
of the southern and central Rocky Mountains and the adjacent High
Plains. Although the bulk of the flow will be oriented parallel to
the mountains, enough of a downslope component will exist to
establish a lee trough in the High Plains.

Coincident with the weak lee trough, a low-level thermal ridge will
develop from the central Texas Panhandle northwest toward the Palmer
Divide. To the west of this thermal ridge axis, hot, dry conditions
will combine with the increasing tropospheric flow to result in
surface winds in excess of 20 mph, with higher gusts. Additionally,
afternoon relative humidity should fall into the single digits to
low teens. The result will be critical fire-weather conditions from
northeast New Mexico into south-central Colorado. Surrounding the
critical area, and extending south-southeast toward southeast
Arizona, sustained winds should be in the 15-20 mph range, albeit
rather gusty. As such, elevated fire-weather conditions are likely
here.

Valid 281200Z - 291200Z

...CRITICAL FIRE WEATHER AREA FOR NORTHEAST NEW MEXICO...SOUTHEAST
COLORADO...FAR WESTERN OKLAHOMA PANHANDLE...AND NORTHWEST TEXAS
PANHANDLE...

...Synopsis...
Closed low over the Great Basin will weaken, open up, and begin to
move east on Monday. To the southeast of the main low/trough,
persistent south-southwest mid-level flow will maintain lee
troughing across the central and southern High Plains, albeit
slightly farther east than previous days. The result will once again
be the overlap of strong, gusty surface winds in excess of 20 mph
and minimum relative humidity in the low teens. As such another day
of critical fire-weather conditions across northeast New Mexico,
southeast Colorado, and the Texas and Oklahoma Panhandles will
occur. Surrounding the critical, elevated fire-weather concerns will
persist, with the duration of winds in excess of 20 mph being the
mitigating factor for higher-end fire-weather concerns.
