Understanding wrap-around low precipitation

When we talk about wrap around precipitation on the backside of low pressure system, those can be a little bit different from typical frontal events. What you can typically expect with these systems is going to be focused on the western side of a cold front. Cooler air with this rain, will bring those lighter, annoying rain showers that aren't too heavy. The possibility of a little bit of snow and wintry mix on the back side of that system also remains possible. These events typically don't last too long as the low pressure system looks to push off to a new area.

So in a typical set up here in Mid-Missouri, we'll see a little bit of a low level jet stream, pulling moisture from the Gulf of Mexico into Mid-Missouri. That's gonna be ahead of some showers and storms that could drive into the region. But what happens is low pressure system is spinning counterclockwise. So all that air that's being pulled in is going to be draped up and over and back off to the west. And that could lead to some of those colder rainfall areas as it gets into this blue sector like that shown on the map above, and that's what we call our cold pool. It could cause just a little bit of light rainfall, but enough to keep you annoyed. And if you get wet enough, it's going to be feeling pretty cold. Now, sometime on these systems, if it gets cold enough on the northern side of this area, we could see that rainfall on the backside turn into snow and could cause some issues depending on what time of the year it is and the actual temperatures.

By next week we could see some cooler wrap-around precipitation after Monday. We'll continue to keep a close eye on it, but it will be leaving us with some cooler temperatures as we head off to the second half of next week
