***Watch WISN 12 News for Milwaukee’s most accurate forecast!***
Thank you for stopping by the Weather Watch 12 blog! If you are looking for relief from the heat and humidity, it is on the way! A cold front will clear southeast Wisconsin early Wednesday afternoon brining with it a drop in humidity and temperatures.
Let’s start out by discussing the rain, or lack of Wednesday morning. As we discussed in yesterday’s blog, we expected the rain to weaken as it arrived across southeast Wisconsin to start the day. In order for thunderstorms to grow you need ample moisture, lift, and instability. With 1-2 ingredients missing, what was a strong line of storms began to diminish just before arriving in our area. Most of the metro did not even see rain early Wednesday.
As the front pushes through around midday, it is possible for a few showers or an isolated t-storm to redevelop. No severe weather or widespread heavy rain is anticipated with any of the showers/t-storms. Rain chances should exit Racine and Kenosha counties by 3 p.m.
The focus will then be on the arrival of cooler and less humid air. The humidity will drop overnight and we should wake up to a great Thursday! Sunshine and highs around 80 are expected! Below is a forecast surface map for 7 a.m. Thursday. The area of high pressure to our west is a welcome site. Just click on the map to enlarge.
The lower dew points will be in full force on Thursday. Below is the dew point forecast from the NAM(North American Model). The colors over our area correspond to dew points in the upper 50s to low 60s.
Finally, I saw this picture a couple of days ago and was amazed. On July 23 a severe thunderstorm produced huge hail around Vivian, SD. One piece of hail had just over an 18″ circumfrence!
Back in 2008 I was caught in baseball size hail near Salina, KS, which was scary. I can’t image what it was like to be in this hailstorm! What is the largest hail you’ve ever seen? Just let me know in the comments section of the blog.
Have a great day!
