Hoosier Posted June 7, 2015 Share Posted June 7, 2015 text on why the enhanced area was added ..PRIMARY CHANGES TO THE DAY-1 CONVECTIVE OUTLOOK /1/ PORTIONS OF NRN IL INTO NWRN INDIANA HAVE BEEN UPGRADED TO THE ENHANCED CATEGORY. AN OUTFLOW BOUNDARY FROM EARLIER CONVECTION CONTINUES ADVANCING NWD ACROSS NRN IL...IN ADVANCE OF A COLD FRONT APPROACHING THE MS RIVER. THE AIR MASS S OF THE BOUNDARY CONTINUES TO DESTABILIZE. MODIFICATIONS TO THE 18Z ILX RAOB FOR TEMPERATURES IN THE UPPER 80S TO AROUND 90F WITH DEWPOINTS OF 68-71F INDICATE MLCAPE AROUND 2500 J/KG AND LITTLE CINH. CONFIDENCE HAS INCREASED IN A FOCUSED AREA OF CONVECTIVE GENERATION INVOF THE OUTFLOW BOUNDARY...ESPECIALLY NEAR THE SYNOPTIC FRONT. GIVEN THE STRONG INSTABILITY IN PLACE...AND H7-H5 LAPSE RATES MEASURED AROUND 6.8 C/KM...INTENSE UPDRAFTS WILL LIKELY ENSUE AS CONVECTION BECOMES SCATTERED TO NUMEROUS IN THE NEXT FEW HOURS. WITH THE ILX AND LOT VWPS INDICATING 1-2-KM-AGL FLOW HOLDING AROUND 30-40 KT AND 35-45 KT OF DEEP SHEAR...CONFIDENCE IS FURTHER BOLSTERED IN STRONG BOWING ELEMENTS CAPABLE OF DMGG WIND GUSTS AS CONVECTION ORGANIZES INTO A QUASI-LINEAR SEGMENT ORIENTED ALONG MEAN CLOUD-LAYER WSWLY FLOW.

OceanStWx Posted June 7, 2015 Share Posted June 7, 2015 Some stuff firing N of QC also Environment is pretty ripe still around Highway 30, but the best combination of instability and OFB is definitely south of I-80 right now. Cell entering Peoria County has a nice 65 dBZ core over 25 kft. Link to comment Share on other sites More sharing options...
OceanStWx Posted June 7, 2015 Share Posted June 7, 2015 DVN probably drops the next warning for the cell up in southern Bureau Co. Link to comment Share on other sites More sharing options...
King James Posted June 7, 2015 Share Posted June 7, 2015 Caught the northern edge of that cell south of Joliet. Heavy downpour and wind with the sun out. Getting soupy feeling around here. Link to comment Share on other sites More sharing options...

Hoosier Posted June 7, 2015 Share Posted June 7, 2015 Looks to be trying to develop a RFD from KLOT. Low level winds are backed right in that area around IKK as well, so certainly one to watch. Link to comment Share on other sites More sharing options...

Hoosier Posted June 7, 2015 Share Posted June 7, 2015 Notice the altered flow around IKK and over into northwest IN. Temps are a bit on the cool side in that area right now, relatively speaking. Link to comment Share on other sites More sharing options...
Chambana Posted June 7, 2015 Share Posted June 7, 2015 88/69 here, clouds with peaks of sun every now and then. Shouldn't be to long before show time. That storm moving just north of Peoria, looks healthy. Link to comment Share on other sites More sharing options...

I wouldn't sleep on the cold front itself, those trailing boundaries can have a few surprises from time to time. Link to comment Share on other sites More sharing options...
Powerball Posted June 7, 2015 Share Posted June 7, 2015 Everything broke up before it made it here to Detroit. Mostly cloudy but with a few peeks of sun, 81 with a 65 dew. Some garden variety stuff has developed just to the WSW. Maybe we can still at least get some cracks of thunder and lightning. I was outside earlier this afternoon and you could really feel the inflow of warm air/moisture. Link to comment Share on other sites More sharing options...
andyhb Posted June 7, 2015 Share Posted June 7, 2015 Looks to be some rotation NW of PIA. I'd watch that storm going up near Odell too, more isolated and will be entering that area of high low level shear. Link to comment Share on other sites More sharing options...
