A very complex weather pattern will unfold across southeastern Wisconsin over the next 24 to 36 hours.  Temperatures will hold steady overnight and start to rise by late Thursday afternoon as a warm front arrives from the southwest.

This warm front will be the focus for showers and storms on Thursday.  The SPC has now upgraded portions of our area into a slight risk for strong to severe storms for Thursday evening.  The greatest chance for severe storms will be along the border of IL/WI where instability will be maximized.

Temperatures tomorrow will spike by the late evening with a southerly wind.  The best chance for storms will be from 7 pm through 11 pm.  Even though we won't have peak heating, there will be enough instability to pop storms with cold air aloft. 

Hail and damaging winds are the main threat; however, there's a ton of shear, so an isolated tornado can't be ruled out.  We will continue to watch the latest model runs and update folks accordingly.
