Halloween features spooky showers and wailing winds with a terrifying temp drop

 

The warm weather from the start of the week is done. We ended up hitting two records for Tuesday and Wednesday with the high of 81 degrees on Tuesday and a low that only dropped to 69 degrees Wednesday shattering the old record of 59 degrees. With thick clouds Wednesday the high only reached 77 so we failed to get to the record of 78.

The big temp drop for Halloween Thursday will be the big story as morning temps bounce around in the upper 50s and 60s then we drop into the 50s come the afternoon and eventually into the 40s for the evening. The wind will also increase during the day with sustained wind from 15-30 mph and the strongest wind arriving during the late afternoon and evening.

Expect the strongest wind gusts to happen during Halloween trick-or-treating with gusts to 50 mph possible. That wind will stay strong through most of Thursday night but by Friday morning lightens up quickly to 5-10 mph and a light wind will continue into Saturday.

Because of the potential for wind gusts to reach 40, 45 or even 50 mph, a wind advisory has been issued for all of southeast Wisconsin from 10 am Thursday to 10 pm. This wind will be stronger than it has the last two days. 

The afternoon temp drop and increase in wind speed will all come shortly after the arrival of the cold front. As of 8:30 AM, that front is currently just moving over the WI border from Iowa with Dubuque, IA reporting a wind gust over 50 mph. While thunder and lightning is not expected with these showers, we have the potential for gusty showers with wind gusts over 50 mph at times. Those showers likely arrival locally between 10 am and Noon.
