.DISCUSSION...

The first of two weather systems this week will begin to impact
the region today, initially with increased southwest winds of
15-25 mph and gusts to 40 mph this afternoon. Winds will likely be
strongest near the International border from Santa Cruz through
Cochise counties. With dry relative humidity values in the 8 to 14
percent range, near critical fire weather conditions are likely.
Critical fire weather conditions will be more limited as coverage
of strongest winds looks inconsistent, outside of a couple hours
of critical conditions in southern areas of Fire Weather zones 151
and 152. Then an area of rain showers and mountain snow will move
through southeast Arizona tonight. A second system is expected to
impact the region beginning Thursday, bringing stronger southwest
wind and then widespread chances for rain and mountain snow.
Minimum relative humidities are expected to be high enough
Thursday to prevent greater fire weather concerns.
