Wettest May gives way to a wet June 1st

May 2019 was the wettest May on record for Chicago, replacing May of 2018 as the wettest. A total of 21 days in May had measurable rainfall which was also a record for the month. May was also an abnormally cloudy month with 47% of the normal sunshine with the normal May sunshine being 56%.

The first day of June will begin with rain and potentially severe storms. Northeast Illinois and northwest Indiana are under a slight risk for severe weather today. The best chance for severe weather will be during the afternoon hours. West central Illinois and a large portion of Missouri and southeastern Kansas are under an enhanced risk for severe weather today.

Monday and most of Tuesday will also be dry. The last time we had three consecutive days without measurable rain was May 13th through May 15th.
