...SEVERE THUNDERSTORMS LIKELY TONIGHT...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL INDIANA.

.DAY ONE...TODAY AND TONIGHT.

OUTLOOK: HOT AND HUMID TODAY. WIDESPREAD THUNDERSTORMS THIS
EVENING AND OVERNIGHT.

HAZARDS: HEAT TODAY. TONIGHT...DAMAGING WIND...LIGHTNING...LARGE
HAIL AND LOCALIZED FLASH FLOODING.

TIMING: BEGINNING NEAR LAFAYETTE BEFORE SUNDOWN THEN RAPIDLY
SPREADING SOUTHEAST TO INDIANAPOLIS AND MUNCIE BEFORE MIDNIGHT.

DISCUSSION: THE STORM PREDICTION CENTER CONTINUES A MODERATE RISK
FOR SEVERE WEATHER ACROSS THE AREA. A MESOSCALE CONVECTIVE SYSTEM
WILL DEVELOP IN NORTHERN ILLINOIS...POSSIBLY BECOMING A DERECHO
AS IT MOVES THROUGH AND BEYOND INDIANA TONIGHT. STRONG WIND SHEAR
ALONG WITH HOT AND HUMID AIR WILL FEED THE STORMS AS A SURFACE
AND UPPER TROUGH HELP MAINTAIN ORGANIZATION.

CONFIDENCE IS HIGH FOR DAMAGING STRAIGHT LINE WINDS IN MANY AREAS.
LARGE HAIL IS ALSO LIKELY BUT SOMEWHAT LESS OF A THREAT. ISOLATED
TORNADOES AND LOCALIZED FLOODING CANNOT BE RULED OUT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH WEDNESDAY.

OUTLOOK: THUNDERSTORMS ARE EXPECTED AGAIN SATURDAY INTO MONDAY
WITH THE GREATEST THREAT OCCURRING SUNDAY. IT IS TOO EARLY TO
DETERMINE IF THESE STORMS WILL BE SEVERE BUT LIGHTNING IS A HAZARD
IN ALL THUNDERSTORMS.

DISCUSSION: LOW PRESSURE WILL TRACK EAST THROUGH THE GREAT LAKES
THIS WEEKEND AND EARLY NEXT WEEK WITH A FRONTAL BOUNDARY IN THE
AREA. THIS SHOULD HELP TRIGGER MULTIPLE ROUNDS OF THUNDERSTORMS.

.SPOTTER INFORMATION STATEMENT...

SPOTTERS WILL BE NEEDED TONIGHT...AND POSSIBLY AS EARLY AS LATE
AFTERNOON.
