Modify the sockclose area like a so:
Line 302: Remove the or !forecast5 from the if statement. This will keep it from spitting out the long info.

 Before
  if (%wu_command == !forecast) || (%wu_command == !forecast5) {
After
if (%wu_command == !forecast)  { 

Lines 324 thru 330. Change the bot from messaging the %wu_nick, to message the channel %wu_chan

  if (%wu_command == !forecast5) {
