The next 24 hours in Chicago bring multiple chances for severe weather that could see heavy rain, hail and the possibility for more tornadoes just days after several struck the region.
But what exactly you'll see and when could shift if and when each system develops - and much uncertainty still remains.
The threat comes after severe weather tore through the Chicago area Friday, bringing wind gusts in excess of 80 miles per hour and at least a dozen tornadoes to the region.
Here's a look at what to expect:
Tuesday Morning and Early Afternoon
Much of the Chicago area was placed under a severe thunderstorm watch Tuesday morning as the first of multiple waves of storms moved in.
The watch remains in effect until 3 p.m.
Counties included under the watch were Cook, DeKalb, DuPage, Grundy, Kane, Kankakee, Kendall, LaSalle and Will in Illinois as well as Lake County in northwest Indiana. Lake and McHenry counties in Illinois were later added to that alert.
A severe thunderstorm warning was also issued for LaSalle County initially as a dangerous storm system had started moving in, prompting forecasters to urge residents to "take cover." Warnings were issued for western Kendall, northern LaSalle and southern DeKalb counties until 1 p.m. and for northern DeKalb, northwestern Kane and southwestern McHenry counties until 1:30 p.m.

Another warning for northern Kendall, central DeKalb and Kane County was in effect until 1:15 p.m.; for Lake, northeastern Kane, McHenry and northern Cook counties until 2:30 p.m.; and northeastern Kendall, northwestern Will, southeastern Kane, DuPage and Cook counties until 2:45 p.m. (Track storms with live radar below)
The alerts warn of "destructive hail" up to the size of a baseball and damaging wind gusts in excess of 70 mph with the storms.
"If you receive a warning, take cover away from windows," the NWS tweeted. "These are dangerous storms!"
According the National Weather Service, storms are possible during the late morning and afternoon hours, particularly north of Interstate 88.

Late Tuesday Afternoon and Evening
The second round of severe weather comes during the late afternoon and throughout the evening hours Tuesday.
Though "there remains considerable uncertainty" surrounding whether or not this round will in fact develop, if it does, "all modes of severe weather would be possible," particularly in northern and western portions of the Chicago area.
The biggest risk with this wave comes between 4 and 10 p.m., according to the NBC 5 Storm Team.
With so much uncertainty surrounding this wave, answers likely won't come until that window, however.
According to the NWS, a "cap" of warm air could protect the Chicago area from seeing severe storms in this wave, but if that cap weakens enough to allow storms to develop, things "will quickly become severe." As of Tuesday morning, NWS reported a 40% chance of storms developing and a 60% chance few or even no storms develop.
Just like Friday’s storms, the main threats with a potential outbreak Tuesday would be damaging hail and wind gusts, along with a chance of isolated tornadoes.
Those storms could then be capable of producing "destructive hail" and possibly more tornadoes, with the potential for "extensive damage."
Wednesday Morning
Storms will again be possible Wednesday morning, some of which could become severe as a cold front pushes into the region.
The NWS said Tuesday that the potential for severe conditions Wednesday "has increased."
"Main threats are from damaging winds, tornadoes, and hail. A relatively higher potential exists along and east of I-55. Severe threat will end in the early aftn," the agency tweeted.
The biggest threat for strong to potentially severe conditions will likely be between 6 a.m. and noon, according to the NBC 5 Storm Team.
As the storms move across the area, temperatures will quickly fall.
