Polls in Maryland to remain open ’til 9:30pm??

From WBAL radio.

But you’ll probably have to use a provisional ballot.
This is supposedly due to the weather.

Is the weather really so bad they have to change the rules mid-stream?
ADDENDUM- That’s Ice out there, not just rain.

Also: Brian Griffiths, Greg Kline, and Mark Newgent report they are on WAMD radio discussing the primary and other info (From Brian’s Blog)
