FORECAST FOCUS ON THUNDERSTORM CHANCES TONIGHT.

BIGGEST QUESTION THIS EVENING IS WHEN AND WHERE THE CAP WILL BREAK.
CONVECTION OVER OUR CWA COULD HAPPEN TWO WAYS. ONE WAY WOULD TO
HAVE SURFACE BASED CONVECTION THIS EVENING WITH HELP FROM THE
SURFACE BOUNDARY CLEARLY VISIBLE ON SATELLITE AND RADAR OVER THE
EAST OVERCOMING THE CAP. THE OTHER WAY CONVECTION COULD HAPPEN IS
WITH AN MCS OVERNIGHT FORMING IN MINNESOTA AND TRACKING THROUGH
WISCONSIN THROUGH THE EARLY MORNING HOURS ON WEDNESDAY OUT IN THE
EAST. THE LATTER SCENARIO LOOKS MORE LIKELY BUT WILL KEEP THINGS
OPEN ENDED IN CASE THE FORMER MATERIALIZES.

SPC HAS US IN A SLIGHT RISK TONIGHT AND WITH GOOD REASON. IF
CONVECTION BREAKS IT WILL HAVE 2500-3500 J/KG CAPES...150-250
HELICITY...AND -7 TO -8 LIFTED INDEX TO WORK WITH. MAIN THREAT
TONIGHT WILL BE FROM HIGH WINDS AND LARGE HAIL. WILL NOT MENTION
SEVERE TONIGHT DUE TO THE CAP OF ABOUT 50 J/KG.

MODELS PROGGING A BREAK IN THE ACTION FOR MOST OF WEDNESDAY AND
WEDNESDAY NIGHT WITH A BRIEF WEAK RIDGE OVER THE AREA.

THE NEXT CHANCE FOR PRECIPITATION IS ON THURSDAY WITH ANOTHER COLD
FRONT MOVING THROUGH THE STATE. AVN PRODUCING TWO DISTINCT LOWS
WITH THIS SYSTEM...ONE OVER NORTHERN CANADA AND THE OTHER OVER
CENTRAL ILLINOIS. ETA PRODUCES ONE LONG FRONT HOWEVER IT HANDLES
THE SITUATION SIMILAR IN THAT THERE ARE TWO DISTINCT PRECIPITATION
MAXIMUMS...ONE OVER SOUTHERN CANADA AND THE OTHER OVER NORTHERN
ILLINOIS WITH MOST OF THE CWA IN BETWEEN. FOR THIS REASON WILL KEEP
PRECIPITATION CHANCES RELATIVELY LOW FOR THIS PERIOD.

.MKX^...NONE.
