New Cloud Types Defined by WMO. The UK Met Office has details: "The cloud species Volutus has been officially named as a new species of cloud in the World Meteorological Organization’s Cloud Atlas. The new cloud species name will now be used by meteorologists operationally around the world. As well as a new species, several new ‘special clouds’ and supplementary features of existing cloud types have been officially recognised in the atlas which is the official publication of cloud types. It is used as a reference document by operational meteorologists around the world and is also an important training tool for meteorologists, as well as for those working in aviation and at sea. Special clouds named in the new edition include: Flammagenitus, which are clouds formed as a result of forest fires; and Homogenitus, which denotes man-made or anthropogenic clouds such as those which form over power station cooling towers. An example of a new supplementary feature is Asperitas, which are well defined wave-like structures in the underside of clouds..."

Speaking of clouds, here's the visible satellite from Saturday, which showed mostly cloudy conditions across much of the state. Note that the only place that really had any sun was across parts of northwestern and far northeastern MN, while the rest of us stared at another slate-gray sky. Unfortunately, it doesn't look like we will see much sun this weekend as another cloudy day is on tap Sunday with a few spotty showers.

Weather Outlook For Sunday
Sunday will be another cool day across the region with highs warming into the 30s and 40s across the state. However, some spots across the Red River Valley will be near 50F by the afternoon.
Weather Outlook For Sunday
Winds on Sunday will be fairly light across the region, but with a little breeze out of the north, it'll feel a little cooler than the actual temperature.
The same storm system that brought parts of the region a few showers earlier this week, will bring us another round of light rain showers on Sunday. Here's the weather potential around midday Sunday, which shows a few showers skirting the eastern part of Minnesota with mostly cloudy skies across the rest of the region.
