Yeah, this thing isn't suddenly going to fall apart. It's well-established and moving into an area with good instability.

Last few frames on the velocity scan suggest it may be losing some of its punch. Should pass through the metro, but this thing won't be long-tracking to WV.

Yeah, that's what I meant...it will make it through the metro at the very least.

MESOSCALE DISCUSSION 1208

   NWS STORM PREDICTION CENTER NORMAN OK

   0548 PM CDT MON JUN 24 2013

   AREAS AFFECTED...NW IL...SRN LK MI...NRN IND...SWRN LWR MI

   CONCERNING...SEVERE THUNDERSTORM WATCH 354...

   VALID 242248Z - 250015Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 354

   CONTINUES.

   SUMMARY...SVR MCS CONTINUES ACROSS NW IL WITH CONTINUED SVR

   WINDS...SOME POSSIBLY SIGNIFICANT...EXPECTED. SVR THREAT WITHIN THE

   LINE IS EXPECTED TO CONTINUE EWD ACROSS SRN LK MI AND INTO SWRN LWR

   MI/NRN IND. AS A RESULT...A DOWNSTREAM WATCH WILL BE NEEDED SHORTLY.

   DISCUSSION...SVR MCS CONTINUES EWD INTO NW IL /INCLUDING THE CHICAGO

   METRO AREA/. ESTIMATED MOTION BASED ON RADAR IS 270/49 KT. STRONG TO

   SVR WINDS HAVE BEEN MEASURED ALONG MUCH OF THE LINE DURING THE PAST

   HOURS. BASED ON RADAR IMAGERY...THE NORTHERN PORTION OF THE LINE HAS

   RECENTLY SURGED EWD...SUGGESTING THE SVR WINDS /SOME POSSIBLE

   SIGNIFICANT/ SHOULD CONTINUE. THE REAR INFLOW JET WAS SAMPLED WELL

   BY DVN VAD WITH A LARGE AREA OF FLOW GREATER THAN 50 KT BETWEEN 3

   AND 6 KM. RADAR IMAGERY HAS ALSO SHOWN WEAKENING ECHOS IN THE WAKE

   OF THE LINE...FURTHER CONFIRMING THE PRESENCE OF A WELL-DEVELOPED

   REAR INFLOW JET.

   AREA DOWNSTREAM OF THE CURRENT LINE ACROSS NRN IND/SRN LWR MI IS

   CHARACTERIZED BY TEMPERATURES IN THE MID 80S AND DEWPOINTS IN THE

   LOW TO MID 60S. CURRENT INDICATIONS FROM VISIBLE SATELLITE IMAGERY

   AND MESOANALYSIS ARE THAT THE AREA IS WEAKLY CAPPED WITH ONLY MODEST

   INSTABILITY /MLCAPE AROUND 1000 J PER KG/. HOWEVER...THE STRENGTH OF

   THE MCS AND THE PRESENCE OF GOOD LOW-LEVEL MOISTURE SHOULD FAVOR

   CONTINUED PROPAGATION INTO THIS AREA. AS SUCH...A DOWNSTREAM WATCH

   WILL BE NEEDED SOON.
