unfortunately...
the synthesized voice that "reads" those weather alerts on Weather Radio (which is also rebroadcast on spare cable channels, etc, in various local markets) probably WON'T be upgraded to something we can understand.
On the other hand, MY ELDERLY MOTHER LIKES THE ALL CAPS WEATHER REPORTS BECAUSE THAT'S HOW SHE TYPES IN EMAILS TO HER FELLOW BLUE-HAIRS, so that's nice I suppose...
