Very ominous looking next to the lake in Kenosha as the wall of read approaches.

Lived on the south side of Kenosha in 2010 when a horrible derecho cleared the lake front parks of their older trees. My neighborhood on Lincoln Rd near Snap on was crushed.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

This is an EXTREMELY DANGEROUS SITUATION with tornado like wind
speeds expected. Mobile homes and high profile vehicles are
especially susceptible to winds of this magnitude and may be
overturned. For your protection move to an interior room on the
lowest floor of a building. These storms have the potential to cause
serious injury and significant property damage.

Intense thunderstorm lines can produce brief tornadoes and widespread
significant wind damage. Although a tornado is not immediately
likely, it is best to move to an interior room on the lowest floor of
a building. These storms may cause serious injury and significant
property damage.

A Tornado Watch remains in effect until 1000 PM CDT for north central
and northeastern Illinois...and northwestern Indiana.

Wow pretty amazing system...

 Mesoscale Discussion 0417
   NWS Storm Prediction Center Norman OK
   0754 PM CDT Fri Mar 31 2023

   Areas affected...Northern and Eastern Illinois...Southeast
   Wisconsin...Western Indiana...Far Southwestern Lake Michigan

   Concerning...Tornado Watch 96...

   Valid 010054Z - 010300Z

   The severe weather threat for Tornado Watch 96 continues.

   SUMMARY...A threat of tornadoes, wind damage and large hail will
   continue across much of WW 96 over the next 2 to 3 hours. Parts of
   WW 96 may need to be extended in time, beyond the 03Z expiration.

   DISCUSSION...The latest radar imagery from Chicago shows a line of
   severe storms moving eastward at nearly 70 knots across northern
   Illinois. This line is located within the nose of a 500 mb jet,
   which is creating very strong large-scale ascent across central and
   northern Illinois. This combined with about 75 knots of deep-layer
   shear, evident on the Chicago WSR-88D VWP, will be very favorable
   for severe storms. In addition, RAP forecast soundings near Chicago
   increase 0-3 km storm-relative helicity into the 300-350 m2/s2 range
   by 02Z. This suggests that the tornado threat will continue early
   this evening as the line approaches the western Chicago Metro.
   Tornadoes will be most likely with supercells embedded in the line,
   and with rotating elements associated with short bowing line
   segments. As the line moves eastward into the Chicago and Milwaukee
   metro areas, wind speeds could reach as high as 80 knots along the
   leading edge of the line.

   To the south, other more discrete storms are located to the east of
   Lincoln, Illinois. This area is just to the north of an 850 mb jet.
   For this reason, a tornado threat will likely be maintained with
   these storms. A widespread wind-damage threat will also be likely
   with the stronger cells, especially if a nearly continuous line
   segment can organize.

They're not suppose to. Someone should be fired.

I emailed the fire chief here for clarification on the second warning siren sounding. First one went off around 6:15pm for the circulation(and very likely tornado) near/over Sherman. The second sounded around 6:36pm with no active warnings over the area. The closest warning was from 6:19pm for a "large and extremely dangerous tornado" near Williamsville, well out of the way of Springfield. A new warning was issued at 6:38pm for a confirmed tornado even further ENE from Springfield.

 

I can't find anything supporting my "all clear" activation. Curious to see if I get a response, but I'll swear to it, they have done it before.

Sirens are still county based so if any of the county is in the warning that's why. They never changed it when warnings went from counties to polygons.

Maybe that's it then, but I know there have been tornado warnings in Sangamon county, usually before they get to me or just after passing and the sirens in town do not sound. Maybe damage reports coming in from Sherman prompted them to sound off again.
