When it comes to summer time weather, most outdoor activities are better without rain, unless you garden, then most of the time its for enough rain so you don’t have to water. However, just like the winter time, the forecast is a bit problematic. While we aren’t trying to accumulate something on the ground so that activities can take place, we are hoping that the rain won’t happen on your stretch of ground. The unfortunate part of the summer is that unless there is a strong cold front that will have showers and thunderstorms up and down it, the probability of getting rain is less, and one person who doesn’t see anything, a few others do. Well, that is how things are shaping up for the weekend.

Friday will be dry as the cold front that is expecting to go through today (Thursday) will be well south of the region and high pressure will be building into the region.

Then Saturday, the low coming out of Canada with a warm front and cold front approaches, for now the day looks dry, but then Saturday night through Sunday, we have the chance of rain.

This system is moving slowly, so it will linger into Monday.

Now let’s look at the numbers…

The chance for precipitation (that is the probability that 0.01″ of rain will fall so sprinkles don’t count) for the weekend for most of northern lower and eastern upper Michigan is about 40%. This means that at any point you have a 40 chance of measurable rain or a 60% chance that you don’t. This can also mean areal coverage, which means that 40% of the area will receive measurable rain. With the very small scales that we are dealing with, that’s about the best that meteorologists can forecast for with the technology that they have. The technology has come along way, but it has a ways to go so that we can pinpoint the information.

So the weekend won’t be a total wash, just watch closely and see what is happening.
