This should work, though I didn't actually test it:

File Name: player.pl - Save this in the zone folder you want to adjust weather for

sub EVENT_ENTERZONE {

	# Set the type of weather desired here
	my $weathertype = 1;	# 0 for none, 1 for rain, 2 for snow
	
	# Check if weather is not already set to the desired type
	if ($zoneweather != $weathertype)
	{
		my $Rain = 1;
		my $Snow = 2;
		if ($weathertype == $Rain)
		{
			# Turn off snow (if it is on) and turn on rain
			quest::snow(0);
			quest::rain(1);
		}
		elsif ($weathertype == $Snow)
		{
			# Turn off rain (if it is on) and turn on snow
			quest::rain(0);
			quest::snow(1);
		}
		else
		{
			# Turn off both snow and rain
			quest::rain(0);
			quest::snow(0);
		}
	}

}
