wisconsinwx Posted August 2, 2011 Share Posted August 2, 2011 Are we talking severe weather here? We haven't even barely made it into August yet... Well, Bow looks like he's given up on summer rains and thunderstorms. I'm not sure myself. No question there's still some summer left, but going by meteorological summer we have four weeks left.

cyclone77 Posted August 2, 2011 Share Posted August 2, 2011 Damaging wind threat is about to increase with the line in far SE. Wisconsin and NE. Illinois. Good luck. You guys are sitting pretty over there. Link to comment Share on other sites More sharing options...

No question there's still some summer left, but going by meteorological summer we have four weeks left. May I remind you that your state's biggest ever single day tornado outbreak occurred on August 18th? Anyway, rotation seems to be increasing on that cell in southern WI/northern IL.

Thundersnow12 Posted August 2, 2011 Share Posted August 2, 2011 two little waa wing type cells just went up in last few scans right on the IL/WI border just ahead of the line. Link to comment Share on other sites More sharing options...

wisconsinwx Posted August 2, 2011 Share Posted August 2, 2011 Lol, we were in the severe thunderstorm watch for all of 30 minutes. I wondered why we were in there to start with. Is the cold front marked by that line of showers just west of MKE, or is it further west? Link to comment Share on other sites More sharing options...

There isn't a single cumulus cloud in the sky here as the boundary approaches. Just mid-level clouds. I guess it's not too surprising given the 27C+ 850mb temps down this way. Think you still have a pretty good shot since you still have plenty of time before the boundary passes. Those storms to the north may dig a little further south once the cool pool really gets going.

Chicago Storm Posted August 2, 2011 Share Posted August 2, 2011 616 PM CDT EXPLOSIVE SEVERE THUNDERSTORM DEVELOPMENT HAS TAKEN PLACE ACROSS SOUTHEAST WISCONSIN AND FAR NE IL. STORMS ARE TAKING ADVANTAGE OF THE 4000+ J/KG OF MLCAPE PRESENT WITH TOPS OCCASIONALLY POPPING UP OVER 60KFT. SEEING INDICATIONS ON WSR-88D OF STORMS BEGINNING TO EVOLVE INTO A BOW ECHO WITH IMPRESSIVE VELOCITY SIGNATURE OVER OVER NE MCHENRY AND NW LAKE COUNTY ILLINOIS. GIVEN THE ENVIRONMENT UPSTREAM WOULD EXPECT THAT THIS LINE WILL BOW ACROSS THE NORTHERN SUBURBS THE NEXT HOUR OR TWO WITH THE POTENTIAL FOR WIDESPREAD AND POTENTIAL LOCALLY SIGNIFICANT WIND DAMAGE. CANNOT RULE OUT A QLCS-TYPE TORNADO ALONG THE LEADING EDGE OF THE LINE GIVEN THE INSTABILITY AND ADEQUATE LOW LEVEL SHEAR...HOWEVER THE PRIMARY HAZARD BY FAR WILL CONTINUE TO BE SIGNIFICANT WIND DAMAGE. FATHER WEST CAP APPEARS TO BE HOLDING FOR NOW ACROSS NORTHWEST ILLINOIS AND EASTERN IOWA...AND CONVECTION MAY HAVE A HARD TIME BACK-BUILDING TOO FAR WEST AS AXIS OF THE SHORTWAVE TROUGH APPEARS TO BE MOVING EAST OF THIS AREA ALREADY.

cyclone77 Posted August 2, 2011 Share Posted August 2, 2011 Latest 1km vis shows a very narrow line of agitated looking cumulus trailing west-southwest from northwest Illinois back into the nose of Iowa. This lines up pretty well with where the boundary lays. Hoping we see some development with this over the next hour or so, but who knows lol.

OceanStWx Posted August 2, 2011 Share Posted August 2, 2011 They need to come up with some different descriptors. You're not supposed to laugh when you read this. AT 521 PM CDT...NATIONAL WEATHER SERVICE DOPPLER RADAR INDICATED A SEVERE THUNDERSTORM CAPABLE OF PRODUCING DESTRUCTIVE HAIL UP TO HEN EGG SIZE...AND DAMAGING WINDS IN EXCESS OF 60 MPH. THIS STORM WAS LOCATED 8 MILES EAST OF DOWNTOWN JANESVILLE...MOVING EAST AT 20 MPH. Hen egg is one of my favorites to use! You're right that it could probably use a better descriptor, but it is actually really difficult to come up with a ball or coin that is exactly 2 " in diameter.

Thin line of agitated cumulus along the above mentioned line looks like it's continuing to build. Some of the towers casting shadows visible on 1km vis now. Could be something reading to pop from Savanna down to northwest of DVN. Link to comment Share on other sites More sharing options...

I think one of the hi-res runs today (maybe the 12z 4km wrf) had a line from SE Wisconsin and a line from Western Illinois merging and exploding over the Chicago area.
