patrick7032 Posted June 4, 2011 Share Posted June 4, 2011 We might be seeing the line near Chicago starting to take off. New warning is mentioning winds up to 70 mph. It has a good updraft in the volume scan. Deep echos pretty tall. Link to comment Share on other sites More sharing options...
Powerball Posted June 4, 2011 Share Posted June 4, 2011 A cell's trying to get going just NNE of Flint. We'll see how that one plays out. Maybe the start of our activity here in Michigan. CU's also starting to re-develop. Link to comment Share on other sites More sharing options...

Yes, I am watching that one. The most promising thing on DTX's radar so far today. Considering the storm motion (likely SE) I'd probably be able to intercept it if it gets going quickly. EDIT: Appears to be moving ESE. Link to comment Share on other sites More sharing options...
hm8 Posted June 4, 2011 Share Posted June 4, 2011 FWIW, DTX's avation update earlier mentioned that the best timing for thunderstorms would be between 22z and 03z....which seems to coinceide well with that little CU line along I-69 moving south.

weathergy Posted June 4, 2011 Share Posted June 4, 2011 DTX mentioned a mid-level cap on the 18z sounding inhibiting initiation, that has likely strengthened in the last couple of hours. We've been having several capping issues this season, will think we luck out and most of the action, once again staying south of the Ohio border. Nothing to see here folks, move along.

weathergy Posted June 4, 2011 Share Posted June 4, 2011 I'm not sure I follow. If you're having capping issues then it would stand to reason that they would only be worse to the south. Apparently not. AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DETROIT/PONTIAC MI 324 PM EDT SAT JUN 4 2011 .SHORT TERM... THIS EVENING AND OVERNIGHT THE 19Z SURFACE ANALYSIS SHOWS WEAK LOW PRESSURE IN THE VICINITY OF SAGINAW BAY WITH A TRAILING COLD FRONT EXTENDING INTO NORTHERN ILLINOIS. A REMNANT OUTFLOW BOUNDARY FROM THE CONVECTIVE SYSTEM THAT ROLLED ACROSS LAKE HURON THIS MORNING /REINFORCED BY THE MARINE LAYER/ ALSO EXTENDS FROM MIDLAND TO JUST SOUTH OF PORT HURON. HOT AND HUMID AIR RESIDES JUST SW OF THIS OUTFLOW BOUNDARY. THE 18Z DTX SOUNDING SHOWS SURFACE BASED CAPE UP TO 3800 J/KG. THE CONVERGENCE ALONG THE COLD FRONT AND OUTFLOW HAS LIKELY NOT BEEN DEEP OR STRONG ENOUGH TO OVERCOME THE MID LEVEL CAP THAT IS SHOWN NICELY ON THE 18Z DTX SOUNDING. MID LEVEL WARMING IN THE WAKE OF THIS MORNINGS MCS HAS LIKELY STRENGTHENED THIS CAP. THE CURRENT WATER VAPOR LOOP DOES HOWEVER SHOW A MID LEVEL SHORT WAVE OVER SOUTHERN WISCONSIN...WHICH IS FORECAST TO ROTATE ACROSS SOUTHERN MICHIGAN BETWEEN 21Z AND 00Z THIS EVENING. IT IS ANTICIPATED THAT THE MID LEVEL COOLING AND LIFT ASSOCIATED WITH THIS WAVE COMBINED WITH MODEST BOUNDARY LAYER FORCING ALONG THE COLD FRONT WILL BE ENOUGH TO BREAK THROUGH THE CAP...LEADING TO SCATTERED TO POSSIBLY NUMEROUS THUNDERSTORMS ACROSS THE AREA.
