Question

How hard rain we can expect on Sunday Apr.20 in Woodstock,Ontario?

Answer 1

The first link below says the whole month of April gets an average of 65.9 mm. Divide that by 30, and you get an average of 2.2 mm per day.

The second link (probably more reliable) says April gets 75.2 mm, averaging 2.5 mm a day. Same source says Woodstock's had a max of 85.6 mm in one April day -- majorly wet! But only 11.6 days in April get rain, so odds are pretty good you'll get none at all.

The final link (probably most reliable) says this April 20 has a 70% chance of rain, though. So I'd divide the 75.2 above by the days with rain (11.6) and say you have a 70% chance of getting 6.5 mm.
