Thanks for the quick work, Doug. Apparently $w_type is only defined on 
line 385 when the command line specifies w-<weatherunderground id>:

# wx_condition.sh KPHX $NODE1 v
/usr/local/sbin/wx_condition.sh: line 407: [: ==: unary operator expected

Weather for Station ID - KPHX
...

# cat -n /usr/local/sbin/wx_condition.sh | grep w_type
    385          w_type="wunder"
    407          if [ $w_type == "wunder" ]
    472          if [[ "$w_type" == "wunder" ]]
    685      if [[ $w_type == "wunder" ]]
