AREAS AFFECTED...SERN MO...SWRN KY...SWRN IND...SRN/WRN IL

CONCERNING...SEVERE POTENTIAL...WATCH LIKELY

VALID 300008Z - 300215Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...A LINE OF TSTMS IS EXPECTED TO CONTINUE PROGRESSING
EWD...GRADUALLY INCREASING IN STRENGTH AS IT ENCOUNTERS A MORE
FAVORABLE ENVIRONMENT. PRIMARY THREAT IS DAMAGING WIND GUSTS BUT THE
STRENGTH OF THE SHEAR SUGGESTS A FEW BRIEF TORNADOES ARE POSSIBLE.

DISCUSSION...A WEAKLY FORCED LINE OF TSTMS CONTINUES TO MOVE EWD
FROM WRN IL AND SERN MO INTO CNTRL/SRN IL. SURFACE ANALYSIS SHOWS
THIS LINE OF STORMS IS WELL AHEAD OF THE COLD FRONT...WHICH IS
EXTENDS ACROSS NWRN IL SWWD ACROSS CNTRL MO AND INTO NERN AR.
DEWPOINTS OVER THE REGION ARE IN THE MID 50S WITH SURFACE
TEMPERATURES IN THE LOW 60S ACROSS W-CNTRL IL AND ERN IND AND IN THE
UPPER 60S ACROSS SERN MO...SRN IL...AND SWRN KY. DESPITE THESE
UNSEASONABLY WARM AND MOIST CONDITIONS...A WARM LAYER BETWEEN 850
AND 700 MB IS KEEPING THE OVERALL INSTABILITY VERY LOW /MLCAPE LESS
THAN 100 J PER KG/. AS A RESULT THIS ACTIVITY IS EXPECTED TO
GRADUALLY MOVE EWD WHILE MAINTAINING AT LEAST THE SAME INTENSITY AS
CURRENTLY OBSERVED. THE LOSS OF DIURNAL HEATING IS EXPECTED TO HAVE
LITTLE INFLUENCE AS STRENGTHENING LLJ COUNTERS ANY TEMPERATURE
DECREASE WITH WAA AND INCREASING LOW-LEVEL MOISTURE. GIVEN THE
CURRENT OBSERVED RADAR TRENDS AND FORECAST...ISOLATED GUSTY WINDS
ARE POSSIBLE AS THE LINE MERGES WITH CELLS DEVELOPING IN THE WAA
AHEAD OF IT. COVERAGE OF SVR WINDS IS UNCERTAIN AND A WW IS NOT
ANTICIPATED ACROSS NRN/CNTRL IL.

HOWEVER...STRENGTHENING CONVECTION ALONG OR JUST AHEAD OF THE FRONT
ACROSS NRN AR AND S-CNTRL MO IS EXPECTED TO MOVE EWD/NEWD INTO SWRN
MO...SRN IL...AND SWRN KY. THIS IS THE AREA WHERE SVR TSTMS ARE
EXPECTED TO DEVELOP DURING THE NEXT FEW HOURS. THE LLJ IS EXPECTED
TO STRENGTHEN...REACHING 70 KT AT 850 MB. 00Z LZK SOUNDING CONFIRMS
THIS WITH 70 KT REPORTED AT 850 MB AND 700 MB. RECENT RADAR TRENDS
HAVE SHOWN A STRENGTHENING TREND WITH THE DEVELOPMENT ACROSS SWRN
IL. A WW WILL LIKELY BE NEEDED AS STORMS MOVE INTO THIS AREA FROM
THE SW.

Flood Potential Outlook 04:13:02.1503018

...HEAVY RAINFALL LIKELY TO RESULT IN FLOODING AND POTENTIALLY
SIGNIFICANT FLOODING LATE TUESDAY INTO TUESDAY NIGHT...

A SLOW MOVING AND STRONG STORM SYSTEM IS FORECAST TO TRANSPORT
RECORD WARMTH AND RECORD LEVEL VALUES OF MOISTURE INTO THE REGION
ON TUESDAY. TO PUT INTO PERSPECTIVE HOW MOIST THE ATMOSPHERE IS
FORECAST TO BECOME...MOISTURE CONTENT BY TUESDAY AFTERNOON WILL BE
COMPARABLE WITH AVERAGE MOISTURE CONTENT OF A TYPICAL JULY DAY AND
MUCH ABOVE AVERAGE FOR EVEN APRIL. THIS RECORD WARM AND MOIST AIR
COMBINED WITH A SLOW MOVING AND STRONG FRONT COULD RESULT IN
WIDESPREAD HEAVY RAINFALL OVER PORTIONS OF THE REGION. AT THIS
TIME...THE GREATEST THREAT OF HEAVY RAINFALL LOOKS EXTEND FROM THE
CHICAGO AREA SOUTHWEST TO LASALLE PERU AND EAST INTO NORTHWEST
INDIANA...BUT EVEN AREAS FARTHER WEST OVER NORTH CENTRAL ILLINOIS
COULD SEE RAINFALL TOTALS OVER AN INCH THE NEXT 48 HOURS.

THIS RAIN WILL FALL ON A GROUND THAT IS FROZEN TO GREAT DEPTHS
RESULTING IN VERY HIGH RUNOFF RATES...WHICH WILL RESULT IN A
FASTER THAN NORMAL RESPONSE ON AREA STREAMS AND RIVERS. THE
QUICKLY INCREASING STREAM FLOW AND RECORD WARM TEMPERATURES WILL
RESULT IN A RAPID BREAK UP OF ICE ON RIVERS AND AN ELEVATED RISK
OF ICE JAM FLOODING.

IN ADDITION TO THE USUAL UNCERTAINTIES WITH RESPECT TO THE
RAINFALL FORECAST...THERE IS ALSO SOME ADDITIONAL UNCERTAINTY IN
THE MAGNITUDE OF THE FLOOD THREAT BECAUSE STREAM FLOW ACROSS THE
AREA IS CURRENTLY BELOW TO MUCH BELOW AVERAGE. DESPITE LOWER THAN
AVERAGE STREAM FLOW...THE FORECASTED MAGNITUDE OF THE RAINFALL
SUGGESTS A HIGH POTENTIAL FOR FLOODING AND SHOULD RAINFALL AMOUNTS
END UP ON THE UPPER END OF THE POTENTIAL RANGE THEN MAJOR FLOODING
COULD OCCUR IN SOME AREAS. THE POTENTIAL FOR ICE JAMS FURTHER
INCREASES THE FLOOD THREAT. PERSONS IN FLOOD PRONE AND LOW LYING
AREAS SHOULD MONITOR LATER FORECASTS AND STATEMENTS ON THE HEAVY
RAIN AND FLOOD POTENTIAL.

A FLOOD WATCH FOR TUESDAY AFTERNOON INTO TUESDAY NIGHT WILL
LIKELY BE ISSUED FOR MUCH OF THE REGION LATER THIS AFTERNOON OR
TONIGHT.

* TIMING...FREEZING RAIN WILL CONTINUE INTO THIS EVENING. BY
EARLY EVENING AIR TEMPERATURES ARE EXPECTED TO RISE ABOVE
FREEZING...HOWEVER SOIL AND PAVEMENT TEMPERATURE MAY REMAIN
BELOW FREEZING ALLOWING PRECIPITATION TO FREEZE TO THE SURFACE.

* MAIN IMPACT...TOTAL ICE ACCUMULATIONS OF UP TO A COUPLE TENTHS
OF AN INCH ARE POSSIBLE.

* OTHER IMPACTS...PAVEMENT AND SOIL TEMPERATURES ARE BELOW
FREEZING...SO ANY LIQUID PRECIPITATION WILL LIKELY FREEZE ON
CONTACT AND RESULT IN ICY AND DANGEROUS TRAVEL CONDITIONS ON
UNTREATED ROADWAYS. WALKWAYS MAY ALSO REMAIN ICY...MAKING
WALKING DIFFICULT AND POTENTIALLY DANGEROUS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

...HEAVY RAINFALL POSSIBLE TUESDAY INTO TUESDAY NIGHT WITH
INCREASED RISK OF FLOODING...

A SLOW MOVING AND STRONG STORM SYSTEM IS FORECAST TO TRANSPORT
UNSEASONABLY WARM AND HUMID AIR NORTH INTO THE REGION ON TUESDAY.
THE TYPE OF AIR THAT IS EXPECTED TO SLIDE OVERHEAD TUESDAY IS MORE
COMMON WITH MID SPRING LIKE AIR. THIS ABNORMALLY WARM AND MOIST
AIR COMBINED WITH A SLOW MOVING AND STRONG FRONT COULD RESULT IN
WIDESPREAD HEAVY RAINFALL OVER PORTIONS OF THE REGION. AT THIS
TIME...THE GREATEST THREAT OF HEAVY RAINFALL LOOKS TO BE IN
NORTHWEST INDIANA AND SOUTHEAST OF INTERSTATE 55 IN ILLINOIS WHERE
1 TO LOCALLY OVER 2 INCHES OF RAINFALL COULD OCCUR.
ELSEWHERE...MODERATE RAINFALL TOTALS OF ONE QUARTER TO THREE
QUARTERS OF AN INCH ARE FORECAST OVER THE NEXT 48 HOURS.

THIS RAIN WILL FALL ON FROZEN GROUND RESULTING IN VERY HIGH RUNOFF
RATES WHICH WILL RESULT IN A FASTER THAN NORMAL RESPONSE ON AREA
STREAMS AND RIVERS. THE QUICKLY INCREASING STREAM FLOW AND RECORD
OR NEAR RECORD WARM TEMPERATURES WILL RESULT IN A RAPID BREAK UP
OF ICE ON RIVERS AND AN INCREASED RISK OF ICE JAM FLOODING ACROSS
THE ENTIRE REGION. IF CURRENT FORECASTS FOR HEAVY RAINFALL VERIFY
THEN THE GREATEST RISK OF FLOODING WILL BE OVER THE VERMILION...
IROQUOIS...AND KANKAKEE RIVER BASINS.

IN ADDITION TO THE USUAL UNCERTAINTIES WITH RESPECT TO THE
RAINFALL FORECAST...THERE ARE SOME ADDITIONAL UNCERTAINTIES
REGARDING THE FLOOD POTENTIAL. FIRST...STREAM FLOW ACROSS THE AREA
IS CURRENTLY BELOW TO MUCH BELOW AVERAGE WHICH SUGGESTS A LOWER
FLOOD THREAT THAN WOULD NORMALLY BE EXPECTED WITH RAINFALL OF THIS
MAGNITUDE IN JANUARY. TEMPERATURES ARE FORECAST TO FALL BELOW
FREEZING AGAIN WEDNESDAY...WHICH COULD SLOW OR STOP THE RUNOFF AS
STORM WATER AS IT FREEZES. DESPITE THESE UNCERTAINTIES THERE DOES
APPEAR TO BE A HEIGHTENED RISK OF FLOODING THIS WEEK...PARTICULARLY
IN AREAS THAT ARE MOST PRONE TO ICE JAMS. PERSONS IN FLOOD PRONE
AND LOW LYING AREAS SHOULD MONITOR LATER FORECASTS AND STATEMENTS
ON THE HEAVY RAIN AND FLOOD POTENTIAL.

Winter Weather Watch, Warning, Advisory 14:47:22.5270958

...FREEZING RAIN ADVISORY REMAINS IN EFFECT UNTIL 9 PM CST THIS
EVENING...

* TIMING...FREEZING RAIN...POSSIBLY MIXED WITH SLEET AT TIME WILL
CONTINUE INTO THIS EVENING. BY EARLY EVENING AIR TEMPERATURES
ARE EXPECTED TO RISE ABOVE FREEZING...HOWEVER SOIL AND PAVEMENT
TEMPERATURE MAY REMAIN BELOW FREEZING ALLOWING PRECIPITATION TO
FREEZE TO THE SURFACE.

* MAIN IMPACT...ICE ACCUMULATIONS OF UP TO A COUPLE TENTHS OF AN
INCH ARE POSSIBLE.

* OTHER IMPACTS...PAVEMENT AND SOIL TEMPERATURES ARE BELOW
FREEZING...SO ANY LIQUID PRECIPITATION WILL LIKELY FREEZE ON
CONTACT AND RESULT IN ICY AND DANGEROUS TRAVEL CONDITIONS ON
UNTREATED ROADWAYS. SIDEWAYS AND WALKWAYS COULD ALSO TURN TO
SHEETS OF ICE MAKING WALKING DIFFICULT AND POTENTIALLY
DANGEROUS.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A FREEZING RAIN ADVISORY MEANS THAT FREEZING RAIN WILL CAUSE
TRAVEL DIFFICULTIES. BE PREPARED FOR SLIPPERY ROADS AND
SIDEWALKS. SLOW DOWN AND USE CAUTION WHILE DRIVING ON ICY ROADS.

Mesoscale Discussion 11:49:15.4212945

AREAS AFFECTED...SERN MN...NERN IA...SWRN WI...NRN IL

CONCERNING...FREEZING RAIN

VALID 271748Z - 272145Z

SUMMARY...FREEZING RAIN WILL CONTINUE TO SPREAD NEWD THROUGHOUT THE
AFTERNOON ACROSS THE AREA WITH PRECIPITATION RATES OF 0.05-0.1 INCH
PER HOUR POSSIBLE /PERHAPS HIGHER IN CONVECTIVELY ENHANCED SHOWERS
AND THUNDERSTORMS/. FREEZING RAIN WILL END OR CHANGE OVER TO
PRIMARILY RAIN FROM SOUTHWEST TO NORTHEAST INTO THE EVENING HOURS.

DISCUSSION...STRONG LOW-LEVEL WARM ADVECTION ASSOCIATED WITH A
MIDLEVEL SHORTWAVE TROUGH MOVING ACROSS THE REGION IS LEADING TO A
BROAD AREA OF CLOUDS AND PRECIPITATION...INCLUDING FREEZING RAIN
ACROSS ERN IA/SRN MN/WRN IL. FARTHER EAST ACROSS NRN IL AND SRN
WI...THE COLUMN HAS CONTINUED TO MOISTEN THROUGH ADVECTIVE AND
EVAPORATIVE PROCESSES. AS PRECIPITATION BEGINS TO REACH THE
SURFACE...IT WILL PRIMARILY BE IN THE FORM OF FREEZING RAIN WITH A
SHALLOW SUB-FREEZING LAYER AT THE SURFACE BELOW A PRONOUNCED WARM
NOSE CENTERED NEAR 850 MB. RECENT LIGHTNING OCCURRENCE OVER SERN
IA/NERN MO SUGGESTS THAT CONVECTIVE PROCESSES MAY AID IN LOCALLY
ENHANCED PRECIPITATION RATES.

AREAS AFFECTED...NWRN INDIANA...NRN/CNTRL/W-CNTRL IL...PARTS OF
E-CNTRL/SERN/S-CNTRL MO

CONCERNING...WINTER MIXED PRECIPITATION

VALID 130017Z - 130615Z

SUMMARY...WINTER MIXED PRECIPITATION WILL INCREASE IN COVERAGE AND
INTENSITY THIS EVENING. THIS WILL INCLUDE THE THREAT FOR FREEZING
RAIN WITH RATES OF 0.05 TO 0.10 IN/HR...WITH LOCALLY HIGHER RATES
ALSO POSSIBLE. FREEZING RAIN WILL BECOME INCREASINGLY LIKELY IN THE
CHICAGO AND ST. LOUIS AREAS AFTER 04Z.

DISCUSSION...A LARGE SHIELD OF CONVECTIVE-DEBRIS-RELATED
PRECIPITATION WITHIN A WARM CONVEYOR BELT WILL CONTINUE TO
OVERSPREAD THE AREA THIS EVENING. THIS ACTIVITY SHOULD PERSIST THE
OVERNIGHT HOURS AS ELEVATED WARM ADVECTION OCCURS THROUGH THE
NIGHT...WITH A TENDENCY FOR HIGHER PRECIPITATION RATES TO SHIFT NEWD
IN TANDEM WITH THE STRONGER ASCENT.

AS SUBFREEZING SFC-LAYER TEMPERATURES UNDERCUT THE ELEVATED WARM
ADVECTION...THE LEADING EDGE OF WINTER MIXED PRECIPITATION WILL
ADVANCE ESEWD ACROSS THE REGION. IMMEDIATELY BEHIND THIS LEADING
EDGE...A 40-70-MILE WIDE CORRIDOR OF POTENTIAL FREEZING RAIN WILL BE
ASSOCIATED WITH LIQUID-EQUIVALENT RATES OF 0.05-0.10 IN/HR. LOCALLY
HIGHER RATES MAY OCCUR OWING TO A MODEST CONVECTIVE ENHANCEMENT
ASSOCIATED WITH NARROW ELEVATED CAPE PROFILES. THE FREEZING-RAIN
CORRIDOR WILL LIKELY MOVE INTO NWRN INDIANA BY 07Z.

SENSIBLE HEAT FLUXES ASSOCIATED WITH PREVIOUSLY FALLEN LIQUID MAY
INITIALLY DELAY THE ONSET OF ICING ON MANY SURFACES...ASIDE FROM
ELEVATED/METAL SURFACES. REGARDLESS...OBSERVATIONS UPSTREAM ACROSS
CNTRL MO INTO NERN OK INDICATE PERSISTENT FREEZING RAIN
OCCURRING...AND SFC ICING WILL BE LIKELY.

TO THE WNW OF THE FREEZING-RAIN CORRIDOR...DEEPER COLD AIR WILL
LIMIT/PRECLUDE MELTING OF DESCENDING HYDROMETERS AND SUPPORT SLEET
AND LIGHT TO OCCASIONALLY MODERATE SNOW. REMAINING PRECIPITATION
WILL PROGRESSIVELY TRANSITION TO SLEET/SNOW FROM WNW TO ESE DURING
THE OVERNIGHT HOURS...ESPECIALLY ACROSS NRN IL. PRECIPITATION RATES
ARE EXPECTED TO DECREASE AREA-WIDE BY 09Z AS STRONGER FORCING FOR
ASCENT SHIFTS NE OF THE AREA.

PLEASE REFERENCE MCD 16 FOR ADDITIONAL DETAILS REGARDING ONGOING
WINTER MIXED PRECIPITATION ACROSS NERN OK...SERN KS...CNTRL MO...AND
W-CNTRL IL.
