.DISCUSSION...Overall quiet weather expected. Temperatures
continue to run a few degrees above normal with afternoon RHs
falling into the single digits. SW winds are expected to develop
by the afternoon, with gusts 10-20 mph. Some clouds are expected
to develop this afternoon and evening, with isolated virga
showers along the Mogollon Rim: confidence is very low on if any
of these would impact the RX site today. Main impacts would be
gusty, erratic winds.

Tonight, expect winds to become light with drainage winds down
toward Black River. Overnight RH recoveries remain poor, only
getting into the upper teens to low 20s.

Saturday will once again see lots of sun and warm temperatures.
Winds will increase slightly compared to today with SW winds in
the afternoon gusting 15-30 mph.
