...Synopsis...
In the wake of the upper-level cyclone departing to the east,
transient ridging aloft will give way to increasingly strong
southwest flow over the southern Rockies. An embedded perturbation
passing overhead will aid in deepening a lee trough over parts of
the southern High Plains Friday. Downslope surface winds are
forecast to increase through afternoon over part of eastern NM and
southeastern CO. Dry southerly return flow is also possible across
parts of the TX Rio Grande Valley. The gusty winds and low humidity
will likely support elevated to locally critical fire-weather
conditions.

...Northeast New Mexico and southern Colorado...
As flow aloft begins to strengthen ahead of the approaching
shortwave trough, a deepening lee trough will bolster westerly
surface flow over northeastern NM and southern CO. Dry downslope
trajectories and daytime heating should support widespread minimum
RH values of 10-15%. Overlapping with sustained surface winds of
15-25 mph, and dry fuels devoid of recent rainfall, several hours of
elevated to locally critical fire-weather conditions are likely over
parts of NM and southern CO.

...Texas Rio Grande Valley...
To the east of the deepening lee trough, southerly winds are forest
to increase through much of the day with the approach of the
upper-level shortwave trough. With limited surface moisture in place
behind the previous frontal passage, dry return flow is expected
over parts of South TX and the central Rio Grande Valley. Periodic
surface wind gusts of 15-20 mph and diurnal RH minimums of 15-20%
may support a few hours of elevated fire-weather conditions.
