Storms straddling I-80 corridor, moving east at 20 mph. These are all capable of LIGHTNING, gusts to 40 mph, & temporary heavy rain. The strongest storm is approaching southwest Cook County (Palos Heights / Orland Park) with gusts 50+ mph. Thunder roars, go indoors! #ILwx #INwx pic.twitter.com/9tg9oGACEP

T-storms will likely continue this evening, with highest coverage along the I-80 corridor. Trends are suggesting the possibility for these storms to continue over the next several hours, and quite possibly lift further north into the I-80 to I-88 corridor. pic.twitter.com/IlbJaD74DI

Storm moving into NW Will Co., just west of our office in Romeoville IL. As you can see, some "scary looking clouds", however, this storm is not severe at this time. Occasional lightning, heavy downpours & wind gusts to 40 MPH are possible in far N Will Co. pic.twitter.com/5lZoX3ZJXX

Widely scattered thunderstorms continue at this time across the area, with a diminishing trend expected over the next several hours. pic.twitter.com/amGndtRp4H

We've certainly earned a break from the heat & humidity, which will arrive behind a cold front tomorrow night and last thru the weekend. Gusty northeast winds will build waves and likely cause dangerous swimming conditions for #LakeMichigan beaches on Friday. #ilwx #inwx pic.twitter.com/qp5Pb4Yus6
— NWS Chicago (@NWSChicago) July 4, 2018
Thursday will be the last day of oppressive humidity & hot temps before a welcome reprieve Friday into the weekend. Highest heat indices are favored to be along/south of the Illinois & Kankakee rivers. #ilwx #inwx pic.twitter.com/ahWpMPWwsH
— NWS Chicago (@NWSChicago) July 4, 2018
On Thursday, one or two rounds of scattered thunderstorms are expected ahead of a cold front. Isolated strong to severe t-storms capable of strong winds are possible except for parts of far northern IL. #ilwx #inwx pic.twitter.com/UTSkS9vzIg

The Harrison-Dever Crib cam shows hazy sky over #Chicago on this #4thOfJuly AM, owing to the very muggy air mass in place. Temps already in mid-upper 70s will rise to around 90° away from IL shore today w/heat indices of 98-108°. Have a happy & safe #IndependenceDay! #ilwx #inwx pic.twitter.com/HyRnL95618
— NWS Chicago (@NWSChicago) July 4, 2018
While not as hot as last week, it is almost as humid & temperatures will still be around 90°. Throw in near calm winds & it will be very uncomfortable with potential for heat-related illness. Here's a short video brief touching on this & scattered storms. https://t.co/xO5bgWD9yc pic.twitter.com/qM5t2VLUVv
— NWS Chicago (@NWSChicago) July 4, 2018
Thursday will also be hot & humid, but that's it for the week, with a reprieve Friday into the weekend. Scattered thunderstorms are expected again Thursday before that reprieve and some storms could be gusty with locally heavy rainfall as well. #ILwx #INwx https://t.co/0Pq2b87TRE pic.twitter.com/khMvo7Vd8A
— NWS Chicago (@NWSChicago) July 4, 2018
High moisture, heat, and light winds will combine to make it uncomfortable today with potential heat-related stress. With many having outdoor plans, it is important to demonstrate heat safety, with frequent breaks and staying hydrated.
