Just a few hours to go until meteor shower http://en.wikipedia.org/wiki/Leonids peak. Estimates of the peak time and associated meteor flux vary a lot, but peak flux is estimated to take place about 20h40m to 22h UT.

Predicting meteor showers and their meteor flux is notoriously difficult. According to some models tonight's meteor flux is estimated to peak at tens to hundreds meteors per hour, some even hint at possible meteor storm with 1000-1500 meteors per hour. So there's a small chance for a show of the lifetime!

Sadly it's 100% cloudy here in Helsinki, Finland.

Tip: deckchair, plenty of warm clothing, no optical aid needed apart from the Mark I eyeball, human for the use of. space.com piece on Leonids 2009: http://www.space.com/spacewatch/091113-2009-leonid-meteor-shower.html

Just don't expect a storm, unless it happens. One or two a minute is a respectable rate.
