Brewers Posted June 23, 2013 Share Posted June 23, 2013 Plenty of instability to work with, sfc based cape around 3500j/kg. Its a shame there's absolutely no shear. Link to comment Share on other sites More sharing options...
Indystorm Posted June 23, 2013 Share Posted June 23, 2013 No shear, but there is some 200 m2/s2 low and mid level helicity east of St. Louis area between the advancing line and that swirling MCS in se IL. Wonder if that can enhance storm potential without upper level shear being present for organized storms. Link to comment Share on other sites More sharing options...
Chitown Storm Posted June 23, 2013 Share Posted June 23, 2013 Line in IL starting to fizzle, especially south of I-88. Although new storms firing around Kankakee moving northward. Wonder if an outflow might catch up to the eastward moving line to spark new development. Link to comment Share on other sites More sharing options...

Thundersnow12 Posted June 23, 2013 Share Posted June 23, 2013 They'll continue to pulse up, gust out, and repeat Too bad there wasn't a legit wave to help those things. 4000 j/kg of SBCAPE and dews 72-75 ahead of it. Link to comment Share on other sites More sharing options...
Chicago Storm Posted June 23, 2013 Author Share Posted June 23, 2013 On the annual fireworks run here in NW. IN...The former severe cell is about to hit. Getting some 30mph outflow winds right now. Link to comment Share on other sites More sharing options...
andyhb Posted June 23, 2013 Share Posted June 23, 2013 18z NAM looks pretty substantial in the western part of the region on Tuesday with that vigorous s/w passing through the area. 40-55 kt LLJ at this time of year is nothing to mess with.

Thundersnow12 Posted June 23, 2013 Share Posted June 23, 2013 Will be interesting to see how fast the boundary layer cools late Tuesday evening, watch out if it doesn't. 5000 j/kg of MLCAPE, low-mid 70 dews and 35-40kts of shear and a 40-50kt LLJ Link to comment Share on other sites More sharing options...
Stebo Posted June 23, 2013 Share Posted June 23, 2013 Tuesday and Wednesday are starting to look very interesting locally. Especially if the GFS ends up being correct with a stronger further south system. Link to comment Share on other sites More sharing options...
