HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE OMAHA/VALLEY NE	       
1200 PM CDT THU JUL 3 2003
 
THIS HAZARDOUS WEATHER OUTLOOK IS FOR PARTS OF EASTERN NEBRASKA
AND SOUTHWEST IOWA.

.DAY ONE...THIS AFTERNOON AND TONIGHT

SEVERE THUNDERSTORMS WILL BE POSSIBLE THIS EVENING OVER EXTREME 
NORTHEAST NEBRASKA...MAINLY NORTHWEST OF A LINE FROM ONAWA TO 
COLUMBUS.  DAMAGING WINDS AND LARGE HAIL APPEAR TO BE THE MAIN 
HAZARDS.  INTENSE DAYTIME HEATING COMBINED WITH MOIST SOUTHERLY FLOW 
WILL MAINTAIN VERY UNSTABLE CONDITIONS OVER MUCH OF THE CENTRAL 
PLAINS THIS AFTERNOON. THUNDERSTORMS ARE EXPECTED TO DEVELOP ALONG A 
COLD FRONT OVER DAKOTAS THIS AFTERNOON AND MOVE SOUTHEAST TOWARD THE 
NORTHERN SECTIONS OF THE OUTLOOK AREA TONIGHT. OTHERWISE...WARM MID 
LEVEL TEMPERATURES SHOULD SUPPRESS THUNDERSTORM ACTIVITY OVER 
SOUTHEAST NEBRASKA AND SOUTHWEST IOWA THROUGH TONIGHT.

HOT AND HUMID CONDITIONS CAN ALSO BE EXPECTED THIS AFTERNOON.
HIGHS WILL REACH 95 TO 100 WITH HEAT INDICES FORECAST TO
CLIMB TO AROUND 105 DEGREES BETWEEN 2 AND 5 PM OVER ALL BUT FAR
NORTHEAST NEBRASKA.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY

SEVERE THUNDERSTORMS ARE POSSIBLE OVER MUCH OF OUTLOOK AREA
FRIDAY INTO FRIDAY NIGHT AS A COLD FRONT SETTLES SOUTH OVER THE
REGION.  THE FRONT WILL INTERACT WITH A HIGHLY UNSTABLE
ATMOSPHERE AND MODERATE WIND SHEAR TO PRODUCE SOME SUPERCELL
THUNDERSTORMS CONTAINING LARGE HAIL AND DAMAGING WINDS. EVEN
THOUGH TORNADOES ARE ALSO POSSIBLE...RELATIVELY WEAK LOW LEVEL
WINDS WILL LIMIT THE TORNADIC POTENTIAL. WARM MID LEVEL 
TEMPERATURES MAY AGAIN TEND TO SUPPRESS THE COVERAGE AND 
INTENSITY OF ANY THUNDERSTORM ACTIVITY.
 
HEAT INDICES COULD AGAIN APPROACH 105 DEGREES FRIDAY AFTERNOON
OVER PARTS OF SOUTHEAST NEBRASKA AND SOUTHWEST IOWA AS HIGH
HUMIDITIES COMBINE WITH HIGHS IN THE 90S.

A RISK OF THUNDERSTORMS CONTINUES ACROSS MUCH OF THE AREA
SATURDAY THROUGH TUESDAY.  COVERAGE AND INTENSITY OF THESE
THUNDERSTORMS WILL BE ASSESSED IN FUTURE HAZARDOUS WEATHER
OUTLOOKS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MAY BE NEEDED THIS EVENING OVER THE NORTHEAST
CORNER OF NEBRASKA AND ACROSS OTHER PARTS OF NORTHEAST NEBRASKA AND 
WEST CENTRAL IOWA LATER TONIGHT.
