AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
1258 PM CDT THU MAY 2 2013

.DISCUSSION...
ISSUED 1045 AM CDT THU MAY 2 2013

A FEW MODIFICATIONS MADE TO THE FORECAST TODAY WITH THE
TEMPERATURES WITH STRONG TEMP GRADIENT FROM HIGHS NEAR 60F
FAR NW AT GALESBURG TO UPPER 70S TO NEAR 80F IN EASTERN IL.
ISOLATED SHOWERS AND THUNDERSTORMS TO BECOME MORE SCATTERED DURING
THE AFTERNOON.

COLD FRONT JUST EAST OF I-55 AT LATE MORNING WAS BEEN SLOWLY
PRESSING EASTWARD THIS MORNING. TEMPS RANGE FROM UPPER 50S NW OF
THE IL RIVER TO THE LOW TO MID 70S EAST OF I-55 AHEAD OF THE COLD
FRONT WITH DEWPOINTS IN THE UPPER 50S AND LOWER 60S. ISOLATED
SHOWERS AND THUNDERSTORMS HAD BEEN DRIFTING NORTHWARD OVER CENTRAL
AND NORTHERN IL SINCE SUNRISE AND MOST OF THESE HAVE BEEN FROM
I-57 WEST. PARTLY SUNNY SKIES OVER MUCH OF IL WITH MORE WIDESPREAD
LOWER CLOUDS OVER IA AND CENTRAL AND NW MO.

EXPECT CONVECTION TO DEVELOP MORE DURING THE AFTERNOON OVER
CENTRAL IL WITH FRONTAL BOUNDARY MOVING VERY LITTLE REST OF TODAY
AS SURFACE AND UPPER LEVEL LOW OVER THE LOWER MS VALLEY LIFTS
NORTHWARD INTO TONIGHT.

.AVIATION...
ISSUED 1255 PM CDT THU MAY 2 2013

ISOLATED SHOWERS AND THUNDERSTORMS EARLY THIS AFTERNOON WILL SEE
SHOWERS BECOME MORE WIDSPREAD DURING THIS EVENING AND CONTINUE INTO
FRIDAY. A COLD FRONT JUST EAST OF I-55 WILL REMAIN NEARLY
STATIONARY THIS AFTERNOON...THEN SLOWLY PUSH EASTWARD INTO EASTERN
IL TONIGHT. STRONG UPPER LEVEL TROF OVER THE GREAT PLAINS WILL
DEVELOP A DEEPENING CUTOFF LOW OF 557 DM AT 500 MB OVER CENTRAL KS
BY MIDNIGHT TONIGHT AND THEN 549 DM AT 500 MB NEAR TULSA IN NE OK
BY 18Z/1 PM FRI. MEANWHILE A 1012 MB SURFACE LOW DEVELOPS AND LIFT
UP ALONG THE WESTERN KY/TN BORDER BY 18Z/1 PM FRI. INCREASING LIFT
AND DEEPER GULF MOISTURE TO ADVECT INTO CENTRAL IL TONIGHT INTO
FRI AND DEVELOP MORE WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS.
NNE WINDS 5-10 KTS TO DEVELOP THOUGH LATER AT CMI WHICH CURRENLY
HAS SSE WINDS AHEAD OF COLD FRONT. WINDS TO GRADUALLY TURN ESE
DURING OVERNIGHT INTO FRIDAY MORNING AND INCREASE TO 10-15 KTS.

.PREV DISCUSSION...
ISSUED 326 AM CDT THU MAY 2 2013
DEEP UPPER LEVEL TROF OVER THE PLAINS THIS MORNING...WITH A COLD
FRONT ADVANCING INTO THE MIDWEST AHEAD OF UPPER SYSTEM. QUIET
WEATHER IN THE EARLY MORNING HOURS WILL SLOWLY CHANGE OVER TO
RAIN SHOWERS FROM WEST TO EAST...CURRENTLY APPROACHING THE MISS
RIVER VALLEY. CONCERNS THROUGH THE MED RANGE OF THE FORECAST
REVOLVE SOLELY AROUND THE UPPER TROF AND THE CLOSED LOW THAT
EVENTUALLY SEPARATES AND MOVES EWD JUST SOUTH OF THE OHIO RIVER
VALLEY. MAJOR ISSUE ASSOCIATED WITH THIS STORM WILL BE THE
POTENTIAL FOR HEAVY RAINS...OVER A PERIOD OF A COUPLE DAYS GOING
INTO THE WEEKEND. MODELS COMING TOGETHER WITH A SLOW AND MORE
SOUTHERLY PROGRESSION OF THE SYSTEM OVERALL...WITH PLENTY OF QPF
IN THE MISS AND IL RIVER VALLEYS.

SHORT TERM...TODAY AND TOMORROW...
COLD FRONT APPROACHING THE REGION AND PRECIP ALONG AND BEHIND IT
EXPECTED TO CONTINUE AS MOISTURE STREAMS INTO THE ERN HALF OF THE
US IN CONJUNCTION TO DEVELOPING LOW PRESSURE SYSTEM OVER CENTRAL
MO FOR THE NEXT COUPLE OF DAYS. PRECIP CHANCES CONTINUE THROUGH
TODAY AND TOMORROW ALONG THE BOUNDARY AND AT THE DEVELOPING
CENTER. DEEP LAYER MOISTURE PUSHING INTO THE REGION WITH AN
ASSIST FROM THE LOW CENTERED OVER THE MISS DELTA THIS
MORNING...RESULTING IN A NEARLY SATURATED COLUMN BY THIS
EVENING. WITH THE INCREASING AVAILABLE MOISTURE AND THE LIFT
BECOMING MORE ENHANCED BY DEVELOPING LOW CENTER OVER THE SWRN
BORDER OF THE STATE INTO TOMORROW...THE HEAVIEST QPF OF THE PD
EXPECTED ALONG THE MISS RIVER VALLEY TOMORROW MORNING AND
EVENING...INTO SATURDAY MORNING.

LONG TERM...SATURDAY THROUGH WEDNESDAY...
CUT OFF UPPER LOW OVER SRN MO/NRN AR RESULTING IN A NEARLY
STATIONARY SFC LOW...IF NOT MILDLY RETROGRADING. LACK OF SIGNIF
FLOW ALOFT KEEPS MIDWEST IN CLOUDS AND RAIN THROUGH THE WEEKEND.
PRETTY WET SATURDAY EXPECTED AS OPEN MOISTURE CONTINUES TO STREAM
INTO THE MIDDLE OF THE CONUS FROM THE GULF COAST. SOME
DISCREPANCIES IN THE FORECAST MODELS ON THE OTHER SIDE OF SATURDAY
WITH REGARDS TO THE LOCATION/INTENSITY OF ANY POSSIBLE DRY SLOT
FEATURE...THE TIMING OF THE EXISTING SHOWERS...AND THE EVENTUAL
EXIT OF THE SYSTEM IN A SIGNIFICANT LACK OF FLOW ALOFT. MAJOR
CONCERN FOR EXTENDED PD OF RAINFALL OVER VERY SATURATED GROUND IN
WESTERN IL ALONG THE MISS RIVER VALLEY AND THE ILLINOIS RIVER
VALLEY. FAR ENOUGH OUT IN TIME...AND ENOUGH UNCERTAINTY WITH
EXACT LOCATION OF THE HIGHEST QPF...WILLING TO MAINTAIN ESF AND
FOREGO FLOOD WATCHES AT THIS TIME. A CLOSER LOOK WILL NEED TO BE
MADE WITH QPF AND FFG HOWEVER... PARTICULARLY ONCE RAIN ON
THURSDAY PRIMES THE AREA FOR THE HEAVIEST RAINFALL ON FRIDAY AND
INTO SATURDAY.  DEEP LOW MOVING INTO THE PAC COAST ON SUN NIGHT
PROVIDING A KICKER. APPROACHING LOW IS VERY BROAD AND RELATIVELY
WEAK. CONCERN THAT EXIT OF LOW MAY STILL BE A BIT QUICK...THOUGH
MODELS ARE HAVING A VERY HARD TIME FINESSING THE ATMOSPHERE IN ITS
WAKE. AS A RESULT...FORECAST A BIT ON THE WET SIDE WITH CHANCE
POPS. BY TUES/WED...FORECAST DRIES OUT ENOUGH TO BRING TEMPS BACK
AROUND TO THE LOWER 70S FOR HIGHS.

...FUNNEL CLOUDS SIGHTED OVER CHAMPAIGN COUNTY ILLINOIS EARLY THIS
AFTERNOON...

A FEW FUNNEL CLOUDS WERE OBSERVED AROUND 1 PM ALONG I-74 BETWEEN
MAHOMET AND CHAMPAIGN.

ATMOSPHERIC CONDITIONS EXIST THIS AFTERNOON ACROSS PARTS OF EAST
CENTRAL ILLINOIS THAT FAVOR THE POSSIBLE FORMATION OF WEAK
CIRCULATIONS ON A PRE-EXISTING BOUNDARY. SOME OF THESE
CIRCULATIONS ARE OCCURRING UNDERNEATH DEVELOPING SHOWERS AND
THUNDERSTORMS...WHERE A FUNNEL CLOUD MAY DEVELOP. ONCE THE RAIN
BEGINS...THE FUNNEL CLOUD DISSIPATES. THE BEST CHANCE OF FUNNEL CLOUDS
INTO MID AFTERNOON WILL BE EAST OF HIGHWAY 51 AND AS FAR EAST AS
I-57.

LOW HANGING CLOUDS CAN ALSO APPEAR TO DIP UP AND DOWN AT TIMES...BUT
THEY WILL NOT SHOW SIGNS OF ANY RAPID ROTATION. AN ACTUAL FUNNEL
CLOUD WILL EXHIBIT SPINNING IN A COUNTER-CLOCKWISE DIRECTION.

IN RARE INSTANCES THESE FUNNELS MAY BRIEFLY TOUCHDOWN. STAY ALERT
AND BE PREPARED TO MOVE TO A SAFE SHELTER IF A FUNNEL CLOUD APPROACHES
THE GROUND.
