More Heavy Rain & Tornadoes Confirmed

***Watch WISN 12 News for the latest weather information!***

Thank you for stopping by the Weather Watch 12 blog!  The threat for more heavy rain exists heading into Saturday.  Certainly not the best news for those that were hit hard by torrential downpours on Thursday. 

A Flash Flood Watch is in effect for all of southeast Wisconsin through Saturday morning.  Rain totals of 1″-2″ are possible in spots.  This should be nothing close to what we saw on Thursday, but with the ground saturated it won’t take much rain to create more problems.  One of the most amazing pieces of flood video came from the U-Local section of  Check it out!  Not sure why one person was holding an umbrella.

One round of storms is possible early Saturday, and with a cold front pushing through during the afternoon, a final chance of storms will exist.

Below is the rainfall forecast from the 18Z GFS.  This puts the heaviest rain in northern Illinois, but as mentioned above, totals over 1″ are certainly possible for parts of our viewing area.  The lighter orange color over eastern Iowa represent possible rainfall of 3″-4″.  The light blue in much of southern Wisconsin is around 1″, with some areas closer to the Illinois border pushing 2″.  Keep in mind a slight shift north or south would lead to a huge difference in rain totals.  It could mean over 2″, or it could mean less than a quarter or half inch!

Remember, if you have a rain total please post it to the comments section of the blog.  Also, you can drop rain totals off on the WeatherWatch 12 Facebook page.

Now a quick look back to Thursday’s incredible weather across our area.  Not only were there floods, but also tornadoes in our area.  So far the National Weather Service has confirmed 4 tornadoes.  Here is a breakdown.

1)  1 mile south of Big Bend, Waukesha County.  EF-2 with winds of 115-120 mph.  Time: 7:02-7:05 p.m.

2) 6 miles SW of Fort Atkinson, Jefferson County.  EF-0 with winds of 65-70 mph. Time: 6:150-6:20 p.m.

3) 6 miles SE of Fort Atkinson, Jefferson County. EF-0 with winds of 65-70 mph. Time: 6:26-634 p.m.

4) 2.8 miles S of Whitewater, Walworth County. EF-1 with winds of 90 mph. Time: 8:32-8:40 p.m.

We will track the potential for more heavy rain on WISN 12 News.  Look for an updated blog on Saturday!

Have a great weekend!
