Thank you stopping by the Weather Watch 12 blog! I hope you are enjoying the weekend so far. The good news is dry weather should stick around right through Sunday!
I was hoping for more sunshine across the region on Saturday, but I’m not shocked that a good deal of high cloudiness streamed in. In this blog we’ll discuss why the clouds rushed in so quickly, and what our prospects are for sun on Sunday. Finally, we’ll look over the next rain chance which moves our way in less than 48 hours.
Let’s start discussing the clouds and where they came from. While Wisconsin is enjoying a dry weekend, parts of the Midwest are completely cloudy with rain showers. The area of rain as of Saturday afternoon was located from Indianapolis west to Kansas City. The radar image below is from shortly after 2 p.m.
While southeast Wisconsin is in no danger of rain this weekend, the area of clouds to the south has been advecting into our region. Here is why. The upper level winds are out of a southwest direction. This is pushing moisture in the middle and upper levels of the atmosphere into our area. This has translated to a lot of alto stratus and cirrostratus clouds.
Below is the wind direction and speed on Saturday afternoon of the upper level winds. Notice, the winds were blowing the clouds from the rain area to the south right into southeast Wisconsin.
The question is will this trend continue. Right now I say yes. More clouds will stream in on Sunday…mainly mid and high clouds off the rain area to the south. Below is a forecast product that measures moisture and type in the atmosphere. This can then be translated into a cloud cover forecast. Our area is shaded in the ice and snow. High clouds are made up of ice and snow since they reside in the upper levels of the atmosphere where temperatures are the coldest. As I mentioned above, this will probably translate into more alto stratus and cirrostratus clouds on Sunday.
Just click on the images to enlarge. And of course, ask as many questions as you would like in the comments section of the blog. I will be more than happy to explain what we are discussing.
So dry on Sunday with filtered sunshine at times. Temperatures coolest near the lake, likely in the upper 50s for highs. That will be mainly due to the northeast winds off the chilly water. Inland areas should make the low to mid 60s. By Sunday night the moisture to the south flows north.
A few spotty rain showers are possible on Monday. But the trend has been for this storm to track farther south. Overall, rain chances for Monday stand at about 30% in Milwaukee, slightly higher near the WI/IL border. Rain amounts will vary from nothing to possibly around a 0.25″ well to the south. Here is our in-house computer model forecast for Monday. Again, for the most updated forecast make sure to watch WISN 12 News!
That is a lot of rain over the Midwest and into the Ohio Valley! We will watch this closely, because a slight shift to the north and Monday could turn into a rainy day, while another 50-70 mile shift south and our viewing area stays dry!
Have a great weekend and I’ll see you on WISN 12 News!
