The BBC's forecasters are currently showing London as dry with sunny intervals from Good Friday to Easter Sunday, with maximum temperatures somewhere between 12C and 23C (which, if we assume the middle of that range) means much the same as today. Their forecast doesn't yet cover Easter Monday.

The Weather Channel largely agrees but adds in some scattered showers on Easter Sunday:

Perhaps, AOL get their weather forecasts from the Daily Express, which constantly seems to be forecasting either heatwaves or snow blizzards?
Anyway, Easter Sunday has GOT to be nice this year. It's my birthday and I wanna go out somewhere!
