.SHORT TERM...
312 PM CDT
THROUGH FRIDAY...
AN AREA OF SHOWERS WITH SOME EMBEDDED THUNDERSTORMS CONTINUES TO
SHIFT TO THE EAST-SOUTHEAST ACROSS THE AREA. THE THREAT FOR ANY
STRONGER STORMS...LOOKS TO REMAIN ACROSS MY FAR SOUTHERN COUNTIES
FOR OVER THE NEXT COUPLE HOURS. OTHERWISE...THIS AREA OF SHOWERS
WILL GRADUALLY SHIFT OUT OF MUCH OF NORTHERN ILLINOIS...WITH ONLY A
FEW LINGERING SHOWERS OVER EAST CENTRAL IOWA EXPECTED TO IMPACT
NORTH CENTRAL ILLINOIS LATER THIS AFTERNOON.
THE UPPER TROUGH OVER THE UPPER GREAT LAKES AND UPPER MID-WESTERN
REGIONS WILL CONTINUE TO AMPLIFY OVER THE CENTRAL CONUS TONIGHT. AS
THIS OCCURS...ANOTHER MID-LEVEL DISTURBANCE AND ASSOCIATED SPEED
MAX...CURRENTLY DIVING SOUTHEASTWARD OVER THE DAKOTAS AND
MINNESOTA...WILL SHIFT OVER THE LOWER GREAT LAKES REGION BY EARLY
FRIDAY MORNING. THIS...ALONG WITH A LOWER LEVEL STRENGTHENING
FRONTOGENETIC CIRCULATION SHOULD RESULT IN ADDITIONAL PERIODS OF
SHOWERS TONIGHT. ESPECIALLY ALONG AND EAST OF THE INTERSTATE 55
CORRIDOR. BECAUSE OF THIS...I HAVE FOCUSED LIKELY POPS IN THE REGION
WITH CHANCE POPS FARTHER WEST.
ADDITIONAL SCATTERED SHOWERS ARE LIKELY ACROSS MUCH OF THE AREA
AGAIN ON FRIDAY AS THE THE UPPER TROUGH AND COLD UPPER LEVEL AIRMASS
MOVES OVERHEAD. THE COMBINATION OF FAVORABLE THERMODYNAMIC
CONDITIONS OVER THE LAKE WITH THIS COLDER AIRMASS...ALONG WITH THE
FAVORABLE FETCH OF NORTH-NORTHEASTERLY WINDS SHOULD HELP DRIVE THIS
ACTIVITY. WE ALSO CANT RULE OUT ANOTHER THUNDERSTORM OR TWO FRIDAY
AFTERNOON AS -20 C 500 MB TEMPERATURES ARE PROGGED TO SHIFT OVER THE
AREA HELPING TO PRODUCE SOME STEEP LAPSE RATES.
STRONG NORTHERLY FLOW DOWN LAKE MICHIGAN WILL LIKELY BUILD SOME
DECENT WAVES BY FRIDAY AFTERNOON...WHICH WILL CRASH ON THE ILLINOIS
AND INDIANA NEAR SHORES WATERS. HOWEVER...THE WINDS MAY NOT BE QUITE
AS STRONG AS PREVIOUSLY THOUGHT...WHICH WOULD RESULT IN WAVES
POSSIBLY REMAINING JUST UNDER 9 FT. THEREFORE...IT WOULD APPEAR
THAT ASIDE FROM HIGHLY VENERABLE SITES ALONG THE LAKE SHORES...THE
THREAT FOR SIGNIFICANT LAKE SHORE FLOODING LOOKS TO REMAIN LOW IN
SPITE OF THE HIGHER WATER LEVELS. HOWEVER...THE SWIM RISK WILL STILL
BE HIGH ON FRIDAY...LIKELY RESULTING IN A RIP CURRENT STATEMENT.

FRIDAY NIGHT THROUGH THURSDAY...
MAIN FORECAST CONCERN IS WITH LAKE EFFECT RAIN SHOWERS AND
POSSIBLY EVEN SOME THUNDER FRIDAY NIGHT INTO SATURDAY DUE TO AN
UNSEASONABLY COLD AIR MASS OVER THE REGION. ADDITIONAL CONCERN
INCLUDES UNSEASONABLY CHILLY LOW TEMPERATURES FOR PARTS OF THE
AREA FRIDAY NIGHT AND SATURDAY NIGHT.
ON FRIDAY EVENING...ANY LINGERING INSTABILITY SHOWERS OVER
NORTHEAST IL AND NW IN WILL TRANSITION TO MORE OF A PURE LAKE
EFFECT SETUP. HEART OF THE COLD AIRMASS FROM THE DEEP COLD UPPER
LOW OVER THE WESTERN GREAT LAKES/MID MS VALLEY WILL BE OVER THE
AREA LATE FRIDAY NIGHT INTO SATURDAY MORNING. 850 MB TEMPS WILL
PLUNGE INTO THE LOW-MID SINGLE DIGITS CELSIUS OVER LAND AREAS AND
SINGLE DIGITS OVER THE LAKE. THIS AND DEVELOPING LAKE EFFECT
CONVERGENCE BAND WILL SET UP IMPRESSIVE LAKE EFFECT PARAMETERS
BASED OFF LATEST LAKE SFC TEMPS. LAKE INDUCED CAPE OF AT OR JUST
ABOVE 1000 J/KG AND EQUILIBRIUM LEVELS APPROACHING 30KFT AGL WILL
RESULT IN A BAND OF LAKE EFFECT RAIN SHOWERS AND POSSIBLY EVEN
ISOLATED THUNDER GIVEN IMPRESSIVE PARAMETERS.
GUIDANCE VARIES SOME ON PLACEMENT AND INLAND EXTENT OF LAKE
EFFECT...BUT FOCUS APPEARS TO BE EASTERN COOK...WILL AND KANKAKEE
COUNTIES INTO NORTHWEST INDIANA MAINLY OVERNIGHT INTO SATURDAY
MORNING. THESE SAME PARAMETERS WILL ALSO BE FAVORABLE FOR
WATERSPOUTS OVER THE LAKE...SO HAVE SOME CONCERN DUE TO NORTHERLY
FLOW FOR A SMALL CHANCE OF A WATERSPOUT MAKING LANDFALL. HAVE
MAINTAINED HIGH LIKELY POPS IN HEART OF LAKE BAND...SURROUNDED BY
CHANCE POPS...BUT MAY BE ABLE TO BUMP TO CATEGORICAL PENDING
TRENDS. THEN ON SATURDAY...EQUILBRIUM LEVELS/INVERSION HEIGHTS
WILL START TO COME DOWN DURING THE AFTERNOON AND CONVERGENCE WILL
DIMINISH. ALSO STILL HIGH SUN ANGLE WILL LIKELY INTERRUPT LAKE
EFFECT BAND...SO GRADUALLY DIMINISHING INTENSITY DURING THE
AFTERNOON AND FOCUS OF POPS SHIFTED EAST A BIT.
REGARDING TEMPERATURES...LAKE INFLUENCE WILL KEEP SHORE AREAS IN
LOW TO MID 50S FRIDAY NIGHT WHILE REST OF AREA DIPS TO THE LOWER
TO UPPER 40S...COLDEST IN NORTH CENTRAL IL. HIGHS SATURDAY WILL
ONLY REACH THE LOWER TO MID 60S EVEN WHERE FULL SUN DEVELOPS OVER
NORTH CENTRAL IL...THEN CLEAR SKIES AND LIGHT WINDS AREA WIDE WILL
SUPPORT SOLIDLY LOW-MID 40S EXCEPT FOR CHICAGO HEAT ISLAND
SATURDAY NIGHT.
THE DEEP UPPER LOW WILL QUICKLY EXIT LATER IN THE WEEKEND WITH
RETURN SOUTHWEST FLOW DEVELOPING AS HIGH PRESSURE SLIDES
SOUTHEAST. HIGHS SHOULD REACH THE UPPER 60S TO AROUND 70 ON SUNDAY
UNDER MOSTLY SUNNY SKIES. CONTINUED SOUTH-SOUTHWEST FLOW MONDAY
THROUGH WEDNESDAY AND RISING HEIGHTS WILL ENABLE A CONTINUED
WARMING TREND...REACHING AROUND 80 TUESDAY/POSSIBLY A BIT WARMER
IN SPOTS/AND LOWER-MID 80S WEDNESDAY. A COLD FRONT LOOKS TO
APPROACH WEDNESDAY NIGHT THROUGH THURSDAY...BRINGING THE NEXT
CHANCE FOR SHOWERS AND THUNDERSTORMS. THE PATTERN COULD REMAIN
MILD AND FAIRLY ACTIVE BEYOND DAY 7 AS ADDITIONAL WEST-SOUTHWEST
MID/UPPER FLOW DISTURBANCES COULD AFFECT THE AREA.
