In addition to the present storms near Louisville the 20z HRRR now shows a line of storms forming around 00z on the IN/IL line and moving east across the state and into MI.  Don't know how much faith to put in this, but it hasn't been as trigger happy as the 3 km NAM in this scenario so it might be something to watch.  And radar now shows some returns from cells starting to form in Iroquois County IL on the IN line.

That clearing over S IL I mentioned this morning did indeed move Into IND with temps in the mid-upper 70's and dews 68-70

winds backed along front'

VAD out of IND showing good turning with height

cells developing on IL/IND border on a wind shift line (SW winds hitting SE)

60 kt mid level jet max  jet max moving into region deep layer shear 50-60 kts

these warm front sets up can be surprises sometimes

a meso...but very conservative...I think its a mistake


MESOSCALE DISCUSSION 0804  
NWS STORM PREDICTION CENTER NORMAN OK  
0607 PM CDT SAT MAY 20 2017  
  
AREAS AFFECTED...NORTH-CENTRAL INDIANA  
  
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY   
  
VALID 202307Z - 210130Z  
  
PROBABILITY OF WATCH ISSUANCE...20 PERCENT  
  
SUMMARY...AN ISOLATED SEVERE THREAT WILL BE POSSIBLE EARLY THIS  
EVENING ACROSS PARTS OF NORTH-CENTRAL INDIANA. STRONG WIND GUSTS,  
HAIL AND PERHAPS A BRIEF TORNADO WILL BE POSSIBLE. DUE TO THE  
ISOLATED NATURE OF THE THREAT, WEATHER WATCH ISSUANCE IS NOT  
EXPECTED.  
  
DISCUSSION...THE LATEST SURFACE ANALYSIS SHOWS A FRONTAL BOUNDARY  
EXTENDING FROM NORTHERN ILLINOIS SOUTHEASTWARD INTO CENTRAL INDIANA.  
A MOIST AND UNSTABLE AIRMASS IS LOCATED TO THE SOUTH OF THE BOUNDARY  
WHERE SURFACE DEWPOINTS ARE GENERALLY IN THE UPPER 60S TO LOWER 70S  
F. THIS IS CONTRIBUTING TO A POCKET OF MODERATE INSTABILITY WITH  
MLCAPE ESTIMATED TO BE BETWEEN 500 AND 1500 J/KG. IN ADDITION, THE  
INDIANAPOLIS WSR-88D VWP SHOWS 0-6 KM SHEAR AROUND 45 KT WITH SOME  
GRADUAL VEERING OF THE WINDS WITH HEIGHT IN THE LOWEST 2 KM AGL.  
THIS SHOULD BE ENOUGH FOR STORM ROTATION AND HAIL WITH THE STRONGER  
CELLS. AS THUNDERSTORMS MOVE NORTHEASTWARD ACROSS THE WARM FRONT, A  
BRIEF TORNADO WILL BE POSSIBLE. STRONG WIND GUSTS WILL ALSO BE  
POSSIBLE. THE SEVERE THREAT IS EXPECTED TO BE SHORT-LIVED DUE TO THE  
RELATIVELY STABLE AIRMASS LOCATED TO THE NORTH OF THE FRONT.

Was seriously considering a quick chase down there, but I would have to book it and the daylight window wouldn't be lasting much longer by the time I get in place.

Don't need to post every warning statement.

Not that big a deal at this point (not like we have a million warnings), but anything from precautionary/preparedness actions on down isn't really necessary.
