No idea what you mean when you say "think Walmart TV", but maybe this could do something like what you seem to require (without the need for batch files):

use strict;
use warnings;

use LWP::Simple;

my $url = 'http://weather.noaa.gov/pub/data/forecasts/zone/pa/paz049.t
+xt';

my @content = grep s/^\.//, split "\n", get $url
  or die "Couldn't get it!\n";

print join "\n", @content;
