Scientists believe that weekdays actually tend to be wetter than weekends, because there is more heat and pollution generated by human activity, like traffic. The extra heat tends to increase precipitation by driving convection, while particulates give rain droplets a centre upon which to form.
Research has discovered that Tuesday is regularly the rainiest day of the week. Data has revealed that rainfall has increased by more than 10 per cent over the last 110 years.
Your question comes up occasionally, but the answer is that precipitation (rain or snow) does not fall more frequently on Saturday or Sunday than on other days of the week. The atmosphere does not operate on the "workweek" cycle, even though most of us do.
A 100% chance of rain could mean buckets of rain all day or just a light sprinkle in the afternoon. All you can tell is you are likely to see some sort of precipitation. Likewise, 20% chance of rain means you're unlikely to see any rain at all today, or 20% of the area is going to be drenched.
His conclusion is that June is, overall, most frequently the wettest month in the U.S. with 2,053 of the 8,535 sites reporting such.

Wrong. It also doesn't mean it will rain 30% of the day. The percent chance of rain (or snow or thunderstorms) is called the “Probability of Precipitation,” or PoP. The figure refers to the chance that the forecast area will see at least 0.01 inches of rain, according to the National Weather Service.

Example 1: I am 100% confident that rain will form, but only 50% of the area will be affected. Plug these numbers into the equation. PoP = 1.0 x 0.5 = 0.5 = 50% Probability of Precipitation. Example 2: I am 50% confident that rain will form, but if it does, I am 100% confident that the entire area will be affected.
An “80% chance of rain” means that there is an 80% chance that rain will fall somewhere within the forecasted area. Rain refers to 0.01 inch or more.

What does it mean when it says 90% rain?
When we say there's a "30% chance of rain," what does it really mean? When we give a percent chance of rain, we as meteorologists know that it will rain at some point that day. The percent is the amount of area coverage or people that will see rain for sure.
IT DOES NOT MEAN...
A 50 percent chance of rain means there is a 50 percent chance for any one spot in the forecast area to get wet during the forecast period.
When the temperatures at the top and middle of the atmosphere are warm but it's below 32° at the surface you get freezing rain which falls as rain until it hits a hard surface and freezes. Sleet is formed by warm air at the top of the atmosphere and cold air in the middle and lower levels of the atmosphere.
Let's look at an example of what the probability does mean. If a forecast for a given county says that there is a 40% chance of rain this afternoon, then there is a 40% chance of rain at any point in the county from noon to 6 p.m. local time.
