Graphics for tomorrow: 80% chance of rain. Forecast immed below: tomorrow 20%. Happens all the time. Why???

I get very confused when my emailed and up-to-date forecasts from Wunderground say (like today) 40% chance of rain, but the underground.com web page says “1%”…
Same source, same weather station I presume, same forecasting models — but a huge difference. WTF? Do I put up my convertible top or not?
This happens in my area too. I always see 80% chance of rain or storms but it rarely coincides with other forcasts and rarely comes to fruition so I assume it is a mistake.... maybe it is supposed to say 30%????? This is a big problem. I really like this site but if the forcast is always full of error then it is useless.

Also love when late in the day the forecasted high in the graphics jumps up nearly 10 degrees over what the high actually was.
