Dense Fog Advisory for Lakeshore counties until 10am. Some visibilities under 1/4 mile. May be a little delayed for morning commute and make sure you call ahead if you have a flight tomorrow morning.
Thank you for stopping by the Weather Watch 12 blog. Thursday started off foggy across southeast Wisconsin. Visibilities were under a quarter mile in spots. Fog is essentially a stratus cloud on the ground.
The low clouds and fog showed up very well on the visible satellite Thursday morning. Below is the visisble satellite from 8am Thursday, the white represents the clouds and fog. Any dark color is land or water.
Using visible satellite imagery can show many things from fog and clouds, to snow on the ground in winter. But remember, the visible uses the light from the sun, so when its dark an infrared satellite must be used.
By the weekend the focus will shift to a big warm-up and also a chance of showers and t-storms. Sunday still looks like the warmest day of the weekend, with highs around or above 80 possible in our area.
If winds turn southwest and sunshine is around, even in Milwaukee highs could get that warm.
This is the fourth time this part of the weather pattern has occurred in our cycling weather pattern. As the cold front slides east, and the surface low moves into the Great Lakes, the forecast surface map for Monday is shown below.
This part of the pattern has occurred before. All between 47-52 days apart. Back on November 14 low pressure moved into the Great Lakes as a cold front had just pushed through Wisconsin.
48 days later, the set-up was the same. Low pressure moved into the Great Lakes, and a strong cold front dropped temperatures to ring in 2011.
This storm system has brought with it a big warm-up, a strong cold front, and precipitation each time through the pattern. As the storm arrives this weekend there will be two main chances for showers and thunderstorms. The timing looks to be Saturday night, and then late Sunday or Sunday night.
Depending when any possible storms clear Sunday morning, and when winds pick up out of the southwest will determine how quickly temperatures warm.
The latest data points to highs around 80 on Sunday. Below is the 12Z NAM temperature forecast.
It appears that we are going to jump right into summer for a day or two! For updates on the weekend and the timing of thunderstorms and possible severe weather, please watch WISN 12 News.
