Today’s focus will be on the first signs of Fall! Those signs appeared over the upper Midwest Tuesday morning. Below is a surface map from 7 a.m. Tuesday, while Milwaukee was sitting at 66 degrees, it was in the upper 30s over northern Minnesota! Even parts of northern Wisconsin saw lows in the mid 40s!
Just click on the map below to enlarge.
After a cool start to the day, temperatures will rebound into the mid to upper 70s by afternoon across much of southeast Wisconsin. If Milwaukee does stay in the 70s on Tuesday, it would be the first high in the 70s since July 31! The sunshine will be filtered both on Tuesday and Wednesday as a disturbance slides to our south. Since dew points are very dry in the low 50s around Milwaukee, that should be enough to keep any rain out of our area.
High clouds can be expected since we are on the northern edge of that disturbance. The high clouds show up well on the visible satellite, this picture was from around 8 a.m. Tuesday. I also labeled the area in Minnesota that had lows in the 30s where skies were clear overnight.
The break from the heat and humidity has been nice, but don’t get too use to it. Highs will be back in the mid 80s for Thursday, along with much higher dew points. Below is a dew point forecast from the 00Z NAM. This forecast map is valid for late Thursday. Notice that dew points could be around 70 again!
If you don’t like the heat and humidity, just remember that September is just a short 2 weeks away, and by that time our average high is 76 with an average low of 59. By the end of September those numbers fall to 67 and 49!
So are you ready for Fall? Or would you like to see the heat and humidity stick around?
Have a great day!
