RCNYILWX Posted May 21, 2014 Share Posted May 21, 2014 Round two incoming shortly. I'm worried about my area not getting missed relatively speaking by this one. Core looks like it's headed right my way. And I don't have a garage. Link to comment Share on other sites More sharing options...

cyclone77 Posted May 21, 2014 Share Posted May 21, 2014 Sup east of CR starting to look a bit frisky. Showing some broad rotation in the lower tilts. Seems to be following an old outflow boundary. Something to keep an eye on. Link to comment Share on other sites More sharing options...

SouthernNJ Posted May 21, 2014 Share Posted May 21, 2014 In addition to the large hail, would expect to see some wind damage reports between Naperville and Lemont. The radars showed very strong gusts in that corridor. Link to comment Share on other sites More sharing options...

Jayhawkers Posted May 21, 2014 Share Posted May 21, 2014 That south suburban Chicago cell is making me very nervous. Hook taking shape, rotation increasing, and turning right. rotation still appears pretty weak... Nonetheless, if it strengthens further, will probably see a TOR warning for the south Chicago metro.

Gilbertfly Posted May 21, 2014 Share Posted May 21, 2014 NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 832 PM CDT TUE MAY 20 2014 .MESOSCALE DISCUSSION... 830 PM CDT ONE LARGE HP SUPERCELL CONTINUES TO MOVE EAST-SOUTHEAST ACROSS FAR NORTHERN WILL AND INTO CENTRAL/SOUTHERN COOK COUNTY AT 820 PM CDT. RADAR SHOWS A STRONG BUT BROAD CIRCULATION WITH AN IMPRESSIVE WIND MAX ON THE LOWEST SCANS. LOOP OF MDW TDWR SHOWS MULTIPLE OCCLUSIONS OF THE RFD WHILE MESO NET SITES SHOW THAT THE OUTFLOW IS RATHER COOL WHICH COMBINED WITH THE BROAD CIRCULATION SUPPORTS A LOW BUT NOT NECESSARILY ZERO TORNADO THREAT. THIS LOW THREAT WILL TRANSLATE DOWNSTREAM ACROSS SOUTHERN COOK COUNTY IN THE NEAR TERM...WITH LAKE COUNTY INDIANA CERTAINLY IN THE THREAT AREA DEPENDING ON EVOLUTION ACROSS COOK. DAMAGING STRAIGHT LINE WINDS AND LARGE HAIL ARE STILL THE MAIN THREAT. OTHERWISE MOIST MID LEVEL WAA CONTINUES TO STREAM NORTHEASTWARD INTO THE FORECAST AREA WHICH WILL LIKELY RESULT IN AT LEAST CONTINUED SCATTERED CONVECTIVE DEVELOPMENT ACROSS NORTHEAST IL...WHILE THE BIGGER SUPERCELL AND ANY ASSOCIATED NEW DEVELOPMENT TRACK INTO NORTHWEST INDIANA. BEYOND THAT THE SYNOPTIC BOUNDARY REMAINS STRETCHED ACROSS CENTRAL IOWA WITH SEVERAL OTHER SUPERCELLS LINED UP ALONG IT. TRAJECTORY OF THESE WOULD TAKE THEM INTO THE NORTHERN CWA WITH THE NEAREST CELL NEARING LEE/OGLE COUNTY. EARLIER STORMS ALONG THE SAME TRACK MANAGED TO WEAKEN AS THEY MOVED EAST THANKS TO WORKED OVER AIR SO THIS MAY BE THE TREND. SEVERAL ADDITIONAL WAVES OF CONVECTION ARE POSSIBLE INTO THE OVERNIGHT HOURS AS WHAT APPEARS TO BE A MID LEVEL WAVE ACROSS CENTRAL IOWA TRACKS EASTWARD.

Powerball Posted May 21, 2014 Share Posted May 21, 2014 00z NAM and RAP actually look somewhat encouraging for tomorrow, even if we miss out on tonight's activity. It tracks the MCS tonight far enough south to allow for some clearing in its wake by sunrise and the air to rapidly destabilize (2000-3000 J/KG) before the cold front passage. That instability holds right through 21z - 00z too... Link to comment Share on other sites More sharing options...
