LJ updates in Russian are here - from user lipski:

A rally's taking place on the steps outside the Trade Unions Palace. Milinkevich is speaking, but what he's saying isn't audible. There're no sound amplifiers and they're using megaphones. People stand and actively support the speakers, but further plans can be neither heard, nor understood. Kazulin and Lebedko are also there.

Kalyakin reports that, according to independent exit polls, less than 50% have given their votes for Lukashenko.

People in the crowd are joking about the heavy snow: that's snow cannons :-))
