Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, May 30, 3:50 AM CDT, 7 hours 20 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
350 AM CDT SUN MAY 30 2004

.DISCUSSION...SEVERE WEATHER OUTBREAK LIKELY ACROSS
CENTRAL/SOUTHEAST ILLINOIS SUNDAY AFTERNOON AND EVENING.

SPC HAS UPGRADED PORTIONS OF CENTRAL ILLINOIS INTO A DAY ONE HIGH
RISK OF SEVERE WEATHER...AT LOCATIONS MAINLY ALONG AND SOUTH OF A
QUINCY TO DECATUR TO EFFINGHAM LINE. REMAINDER OF CENTRAL/SOUTHEAST
ILLINOIS IN A MODERATE RISK. MODELS ARE IN GOOD AGREEMENT WITH THE
TIMING OF THE ASSOCIATED SURFACE FRONT...ALL SHOWING A SLIGHT
SLOWING OF TIMING FROM 24 HOURS AGO. ALL INSTABILITY/SHEAR
PARAMETERS...EXTENT OF UPPER LEVEL SUPPORT AND TIMING OF SURFACE
BOUNDARY SUPPORT THE RISK. THIS WILL BE THE SHORT-TERM FORECAST
CHALLENGE.

LATER ON...MODELS NOW IN BETTER AGREEMENT WITH AN UPPER LEVEL LOW
CUTTING OFF ACROSS THE GREAT LAKES REGION. ETA NOW MORE SIMILAR WITH
THE GFS...WHICH ALL ALONG SUPPORTED A LESS PROGRESSIVE SCENARIO WITH
THIS FEATURE. THIS UPPER LOW WILL KEEP TEMPERATURES COOLER OVER MUCH
OF THE UPCOMING WEEK...WITH PERIODIC THUNDER CHANCES WITH SPOKES OF
SHORTWAVE ENERGY/COOLER H500 TEMPS ROUNDING THE UPPER LOW. HAVE
LEANED TOWARD THE GFS GIVEN ITS BETTER CONTINUITY WITH THIS FEATURE.

SHORT TERM...TODAY AND TONIGHT...
06Z ETA MODEL INDICATES ENOUGH UPPER LEVEL DIVERGENCE ON THE EDGE OF
THE 850H THETAE AXIS TO SUPPORT ONGOING SCATTERED CONVECTION...MAINLY
ALONG AND NORTH OF A PEORIA TO MATTOON LINE. BEST LOW-LEVEL JET AXIS
REMAINS WEST OF THE MISSISSIPPI RIVER TONIGHT...HELPING TO SUPPORT
WIDESPREAD CONVECTION ACROSS IOWA/NORTHWEST MISSOURI. LACK OF
WIDESPREAD RAINS IN CENTRAL ILLINOIS EARLY ON WILL ALLOW AIRMASS TO
QUICKLY BECOME UNSTABLE THIS MORNING. ETA SHOWS SURFACE DEWPOINTS
QUICKLY RISING INTO THE LOWER 70S ACROSS CENTRAL ILLINOIS AS THE
WARM FRONT TO OUR SOUTH QUICKLY LIFTS NORTH. NEGATIVELY TILTED
LONGWAVE TROF WILL NUDGE EASTWARD...WITH THE ASSOCIATED SURFACE
FRONT EXPECTED TO MOVE THROUGH WESTERN PORTIONS OF AREA LATE
AFTERNOON/EARLY EVENING TIME FRAME. ETA SURFACE LI/S SUGGEST -6 TO
-8 WITH CAPES APPROACHING 3000 J/KG. ESPECIALLY DURING THE LATE
AFTERNOON/EARLY EVENING ACROSS THE WEST...SHEAR PROFILES ARE
IMPRESSIVE...WITH LOTS OF TURNING OF WINDS IN THE LOW LEVELS. THE
STORMS WILL LIKELY TAKE ON MORE LINEAR CHARACTERISTICS AS IT MOVES
THROUGH EASTERN ILLINOIS...AS WIND PROFILES BECOME MORE
UNIDIRECTIONAL PER BUFKIT. WILL ONLY MAKE MINOR ADJUSTMENTS TO
FINE-TUNE GRIDS FOR THIS OUTBREAK...BUT LITTLE AS FAR AS CHANGES
NEEDED. BECAUSE EXPECTED HEAVIER RAINFALL REMAINED WEST OF ILLINOIS
TONIGHT...NOT LOOKING AT FLOODING BEING A MAJOR ISSUE. WILL
CONCENTRATE ON THE SEVERE WEATHER EXPECTED. THERE SHOULD BE ENOUGH
SPEED TO THE FRONT TO DIMINISH THE CHANCES OF WIDESPREAD FLOODING
PROBLEMS.

LONG TERM...MEMORIAL DAY (MONDAY) THROUGH SATURDAY...
AS STATED EARLIER...UPPER LOW IS EXPECTED TO DEVLOP ACROSS GREAT
LAKES REGION AND DROP THROUGH UPPER MIDWEST. THIS FEATURE AND ITS
ASSOCIATED COLD TEMPERATURES ALOFT...TO BRING MAINLY DIURNAL STORM
CHANCES TO THE AREA INTO WEDNESDAY. GFS HAS BEEN FAIRLY CONSISTANT
WITH THIS SCENARIO. DIFFICULT TO TIME EXACT TIMING ON RAIN CHANCES
WITH THE APPROACHING WAVES...GFS CURRENTLY SUGGEST THE MOST
AMPLIFIED WAVE TO MOVE THROUGH CENTRAL ILLINOIS MORNING-MIDDAY
WEDNESDAY. THEREAFTER...UPPER LEVEL RIDGING TO BUILD INTO THE
AREA...ALLOWING FOR A WARMING TREND INTO NEXT WEEKEND.

...THERE IS A HIGH RISK OF A SEVERE WEATHER OUTBREAK THIS AFTERNOON
INTO THIS EVENING WITH THE POTENTIAL FOR SIGNIFICANT LONG-TRACKED
TORNADOES...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR CENTRAL AND SOUTHEAST ILLINOIS.

.DAY ONE...TODAY AND TONIGHT

AFTER SCATTERED THUNDERSTORMS DEPART THE AREA THIS MORNING...MORE
THUNDERSTORMS WILL DEVELOP BY MID-AFTERNOON AND LAST INTO THE
EVENING HOURS. MANY OF THESE STORMS WILL BE SEVERE...PRODUCING VERY
LARGE HAIL AND DAMAGING WINDS. THE POTENTIAL ALSO EXISTS FOR
TORNADOES...A FEW OF WHICH MAY BE LARGE AND PRODUCE LONG DAMAGE
TRACKS. THE TIME FRAME FOR THE MOST INTENSE THUNDERSTORMS WILL BE
FROM AROUND 2 PM UNTIL 8 PM. AFTER THAT...THE STORMS ARE EXPECTED TO
EVOLVE INTO A SEVERE SQUALL LINE OVER THE EASTERN HALF OF THE
AREA...PRODUCING MAINLY DAMAGING WINDS. MOST OF THE SEVERE WEATHER
SHOULD MOVE EAST INTO INDIANA BY MIDNIGHT.

TORRENTIAL RAINFALL WILL ACCOMPANY SOME OF THE STORMS. SINCE THE
GROUND IS STILL SATURATED FROM PREVIOUS RAINFALL OVER SOUTHEASTERN
ILLINOIS...FLASH FLOOD CONDITIONS MAY RETURN TO THAT PORTION OF THE
AREA IN ADDITION TO THE SEVERE THUNDERSTORMS.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

A DISTURBANCE IN THE UPPER ATMOSPHERE WILL LINGER OVER THE GREAT
LAKES MONDAY THROUGH WEDNESDAY...LEADING TO A CHANCE FOR AFTERNOON
AND EVENING SHOWERS AND THUNDERSTORMS.

.SPOTTER ACTIVATION STATEMENT...

SPOTTER ACTIVATION WILL LIKELY BE REQUIRED THIS AFTERNOON AND
TONIGHT FROM AROUND 2 PM UNTIL MIDNIGHT.
