With daytime readings forecast to reach the mid and upper 50s, Tuesday promises to be the first day to post a temperature surplus since March 19th. Thus far, the highest temperature recorded at O’Hare airport this month was a 57-degree reading on the 18th. Tuesday’s Warm-up will be fleeting as a series of cold fronts are to make their way across the region the latter half of the week. Current forecasts suggest the period from March 30th, through April 5th will average around 10 degrees below normal. One benefit of having a chilly start to spring is that severe weather will remain absent. Unless thunderstorms develop early Tuesday, it appears that March, 2018 will be only the second month since January of 2017, that the city has not had a thunderstorm. The other was during a drought period this past September.
