...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.
