Hazardous Weather Outlook

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...TONIGHT.

WEATHER HAZARDS EXPECTED:

THUNDERSTORMS...THE STRONGEST STORMS MAY PRODUCE:

GUSTY WINDS TO 40 MPH.
BRIEF DOWNPOURS.
FREQUENT LIGHTNING.

AREAS AFFECTED AND TIMING:

SCATTERED THUNDERSTORMS MAY DEVELOP ACROSS THE ENTIRE FORECAST
AREA THROUGH EARLY THIS EVENING.

DISCUSSION:

DISSIPATION OF CONVECTIVE DEBRIS ACROSS THE REGION WILL CONTINUE
TO ALLOW FOR MODEST DESTABILIZATION THROUGH EARLY THIS EVENING.
THIS...IN COMBINATION WITH AN APPROACHING COLD FRONT...WILL BRING
A THREAT OF THUNDERSTORM DEVELOPMENT DURING THE LATE AFTERNOON
AND EARLY EVENING HOURS.

LOW LEVEL FORCING HAS BEEN DISRUPTED BY LAST NIGHTS
CONVECTION...AND PROFILER WINDS SUGGEST BETTER MOISTURE
CONVERGENCE WILL BE FOCUSED FROM NORTHEAST OF THE KANSAS CITY
AREA...INTO CENTRAL AND NORTHEAST INDIANA. IN ADDITION...STRONGER
MID LEVEL DYNAMIC FORCING FOR ORGANIZED STORMS WILL LIFT NORTHEAST
ACROSS THE UPPER GREAT LAKES REGION IN ASSOCIATION WITH A
VIGOROUS SHORT WAVE MOVING ACROSS SOUTHERN ONTARIO.

IN SUMMARY...THOUGH THE OUTLOOK AREA IS NOT OUT OF THE WOODS IN
TERMS OF THUNDERSTORM DEVELOPMENT...CONDITIONS APPEAR UNFAVORABLE
FOR ORGANIZED...SEVERE STORMS.

PORTIONS OF THE UPPER ILLINOIS RIVER WILL REMAIN NEAR BANK FULL.
PERIOD OF HEAVY RAIN TODAY COULD LEAD TO RENEWED RISES ON AREA
STREAMS AND RIVERS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.

PORTIONS OF THE UPPER ILLINOIS RIVER WILL REMAIN NEAR BANK-FULL
THROUGH SUNDAY EVENING.

HIGH TEMPERATURES ARE EXPECTED TO REACH WELL INTO THE 90S ON
FRIDAY...IN COMBINATION WITH DEW POINTS IN THE LOWER 70S. THIS
WILL PRODUCE HEAT INDEX VALUES BETWEEN 100 AND 105 FRIDAY
AFTERNOON.

THERE IS A CHANCE OF THUNDERSTORMS FRIDAY NIGHT AND SATURDAY.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION IS NOT EXPECTED THROUGH TONIGHT.

WEATHER HAZARDS EXPECTED:

THUNDERSTORMS...THE STRONGEST STORMS MAY PRODUCE:

GUSTY WINDS TO 50 MPH.
BRIEF DOWNPOURS.
FREQUENT LIGHTNING.

AREAS AFFECTED AND TIMING:

SCATTERED THUNDERSTORMS MAY DEVELOP ACROSS THE ENTIRE FORECAST
AREA DURING THE MID TO LATE AFTERNOON HOURS AND CONTINUE INTO
EARLY THIS EVENING.

DISCUSSION:

DECAYING THUNDERSTORM COMPLEX OVER SOUTHERN ILLINOIS...AND
A MID LEVEL...THUNDERSTORM INDUCED CIRCULATION EXITING THE AREA
TOWARD SOUTHWEST LOWER MICHIGAN HAVE ACTED TO GREATLY STABILIZE
THE AIR OVER NORTH AND CENTRAL ILLINOIS AND NORTHWEST INDIANA.

CONVECTIVE DEBRIS ACROSS THE REGION WILL CONTINUE TO DISSIPATE
QUICKLY HEADING INTO EARLY THIS AFTERNOON AND INCREASED SUNSHINE
WILL ALLOW FOR MODEST DESTABILIZATION TO THE POINT THAT THERE WILL
BE A THREAT OF RENEWED THUNDERSTORM DEVELOPMENT DURING THE MID TO
LATE AFTERNOON HOURS.

HOWEVER...THE REGION SOUTH AND WEST OF THE OUTLOOK AREA IS
EXPECTED TO BECOME MUCH MORE UNSTABLE...WITH MID LEVEL LAPSE RATES
RATHER STEEP OVER SOUTHWEST MISSOURI AND OVER WESTERN IOWA. LOW
LEVEL FORCING HAS BEEN DISRUPTED BY LAST NIGHTS CONVECTION...AND
PROFILER WINDS SUGGEST BETTER MOISTURE CONVERGENCE WILL BE
FOCUSED ALONG BOUNDARY FROM NORTHEAST OF KANSAS CITY AREA...INTO
THE LOWER OHIO VALLEY. IN ADDITION...STRONGER MID LEVEL DYNAMIC
FORCING FOR ORGANIZED STORMS WILL LIFT NORTHEAST ACROSS THE UPPER
MISSISSIPPI VALLEY THIS AFTERNOON IN ASSOCIATION WITH A VIGOROUS
SHORT WAVE MOVING ACROSS THE UPPER GREAT LAKES REGION.

IN SUMMARY...THOUGH THE OUTLOOK AREA IS NOT OUT OF THE WOODS IN
TERMS OF SEVERE THUNDERSTORM DEVELOPMENT...CONDITIONS APPEAR
UNFAVORABLE FOR ORGANIZED...WIDESPREAD SEVERE STORMS.

PORTIONS OF THE UPPER ILLINOIS RIVER WILL REMAIN NEAR BANK FULL.
PERIOD OF HEAVY RAIN TODAY COULD LEAD TO RENEWED RISES ON AREA
STREAMS AND RIVERS.

Hazardous Weather Outlook

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...TODAY AND TONIGHT.

WEATHER HAZARDS EXPECTED:

THUNDERSTORMS...THE STRONGEST STORMS MAY PRODUCE:

WINDS IN EXCESS OF 60 MPH.
HEAVY DOWNPOURS.
FREQUENT LIGHTNING.
HAIL TO THE SIZE OF QUARTERS.
ISOLATED TORNADOES.

AREAS AFFECTED AND TIMING:

A STRONG LINE OF THUNDERSTORMS IS MOVING INTO THE SOUTHERN TIER OF
COUNTIES THIS MORNING...AND MAY BE CAPABLE OF PRODUCING SEVERE
WINDS. SHOWERS WILL OVERSPREAD THE FORECAST AREA THIS
MORNING...WITH A FEW EMBEDDED NON-SEVERE THUNDERSTORMS POSSIBLE.
SEVERE THUNDERSTORMS ARE POSSIBLE AGAIN THIS AFTERNOON AND EVENING
AHEAD OF A COLD FRONT.

DISCUSSION:

ONGOING THUNDERSTORMS THIS MORNING ARE EXPECTED TO WEAKEN AS THEY
MOVE EAST INTO MORE STABLE AIR. A WARM FRONT WILL WORK NORTH
ACROSS THE FORECAST AREA TODAY USHERING IN WARM AND MOIST AIR
BEHIND. THUNDERSTORMS ARE EXPECTED TO REDEVELOP THIS AFTERNOON AND
EVENING AHEAD OF A COLD FRONT...AND SOME MAY BE SEVERE. THERE IS
SOME POTENTIAL FOR SUPERCELLS AND TORNADOES SHORTLY AFTER
THUNDERSTORMS INITIALIZE...HOWEVER THUNDERSTORMS ARE EXPECTED TO
QUICKLY CONGEAL INTO A LINE WITH DAMAGING WINDS AND LARGE HAIL
BECOMING THE PRIMARY THREATS.

PORTIONS OF THE UPPER ILLINOIS RIVER WILL REMAIN NEAR BANK FULL.
PERIOD OF HEAVY RAIN TODAY COULD LEAD TO RENEWED RISES ON AREA
STREAMS AND RIVERS.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.

PORTIONS OF THE UPPER ILLINOIS RIVER WILL REMAIN NEAR BANK-FULL

AREAS AFFECTED AND TIMING:

THERE IS A CHANCE OF THUNDERSTORMS...GENERALLY ACROSS NORTHERN
ILLINOIS LATE TONIGHT.

DISCUSSION:

AN INFLUX OF WARM HUMID AIR IS EXPECTED TO REACH NORTHERN
ILLINOIS AND NORTHWEST INDIANA OVERNIGHT. THIS MAY ALLOW MORE
WIDESPREAD THUNDERSTORM ACTIVITY OVER IOWA AND MISSOURI THIS
EVENING...TO DEVELOP EASTWARD INTO THE FORECAST AREA...ESPECIALLY
ACROSS WESTERN AND SOUTHERN PORTIONS OF THE OUTLOOK AREA. THESE
STORMS MAY REACH AREAS WEST OF INTERSTATE 39 ABOUT MIDNIGHT OR

MOVES ACROSS THE FORECAST AREA. SOME STORMS MAY BECOME SEVERE
MONDAY AFTERNOON AND EVENING.

PORTIONS OF THE UPPER ILLINOIS RIVER WILL REMAIN NEAR BANK-FULL
THROUGH SUNDAY EVENING. PERIODS OF HEAVY RAINFALL MONDAY AND
MONDAY EVENING MAY CAUSE ADDITIONAL RISES ON AREA STREAMS AND
RIVERS.

HIGH TEMPERATURES ARE EXPECTED TO REACH WELL INTO THE 90S ON

THE AFTERNOON...WITH SOME OF THE STORMS POSSIBLY BECOMING
SEVERE. THE STRONGEST STORMS WILL PRODUCE BRIEF HEAVY

FURTHER UPDATES.

Short Term Weather

.NOW...
SCATTERED SHOWERS AND THUNDERSTORMS WERE MOVING ACROSS PARTS
OF NORTH CENTRAL AND NORTHEAST ILLINOIS THIS AFTERNOON.
AT 1215 PM CDT...THE PRECIPITATION WAS MAINLY DEVELOPING WEST OF
INTERSTATE 39. WHILE THE VAST MAJORITY OF THE AREA IS DRY...
EXPECT SHOWERS AND THUNDERSTORMS TO BECOME MORE WIDESPREAD
THROUGH THE AFTERNOON. THE STRONGEST STORMS WILL BE CAPABLE OF
PRODUCING HEAVY DOWNPOURS AND SMALL HAIL.

Hazardous Weather Outlook

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

.DAY ONE...THIS AFTERNOON AND TONIGHT.

WEATHER HAZARDS EXPECTED:

SCATTERED THUNDERSTORMS...SOME A FEW OF THE STRONGER STORMS MAY
PRODUCE:

DAMAGING WINDS...LARGE HAIL...FREQUENT LIGHTNING...HEAVY
DOWNPOURS.

AREAS AFFECTED AND TIMING:

THUNDERSTORMS WILL CONTINUE TO DEVELOP IN NORTHWEST AND WEST
CENTRAL ILLINOIS DURING THE LATE MORNING AND BECOME MORE NUMEROUS
AS THEY SPREAD INTO NORTH CENTRAL AND NORTHEAST ILLINOIS EARLY TO
MID AFTERNOON...AND NORTHWEST INDIANA DURING MID TO LATE
AFTERNOON. THUNDERSTORMS ARE EXPECTED TO CONTINUE THROUGH TONIGHT
ACROSS THE AREA...MAINLY DURING THE EVENING HOURS.

DISCUSSION:

ISOLATED WERE THUNDERSTORMS DEVELOPING UPSTREAM OF THE LOCAL AREA
DURING THE LATE MORNING. THEY WILL CONTINUE TO INCREASE IN NUMBER
AND STRENGTH THIS AFTERNOON AS THEY MOVE INTO THE OUTLOOK AREA AS
DAY-TIME HEATING COMBINED WITH MID LEVEL COOLING ASSOCIATED WITH
AN APPROACHING SHORT WAVE TROUGH RESULT IN A CONTINUED
DESTABILIZATION OF THE ATMOSPHERE OVER THE AREA. THE DISTURBANCE
APPROACHING FROM MISSOURI WILL ALSO PROVIDE ORGANIZED LIFT ACROSS
THE AREA THIS AFTERNOON INTO THIS EVENING. MODELS SHOW THAT THE
THUNDERSTORMS WILL BE MOVING AT A RATHER QUICK SPEED SO WHILE
BRIEF HEAVY DOWNPOURS MAY OCCUR ONLY LOCALIZED FLOODING OF POOR
DRAINAGE AND LOW-LYING AREA CAN BE EXPECTED.

PORTIONS OF THE KANKAKEE AND ILLINOIS RIVERS WILL REMAIN IN
FLOOD.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.

THERE WILL BE PERIODIC CHANCES FOR THUNDERSTORMS FOR THE ENTIRE
OUTLOOK AREA WEDNESDAY AND AGAIN LATE IN THE WEEKEND.

PORTIONS OF THE KANKAKEE AND ILLINOIS RIVERS WILL REMAIN IN
FLOOD.
