Flood Potential Outlook 05:54:04.2103155

...HEAVY RAINFALL POTENTIAL THIS WEEKEND...

THE REMNANTS OF TROPICAL CYCLONE ISAAC WILL MOVE NORTH INTO THE
MID MISSISSIPPI VALLEY BY LATE FRIDAY NIGHT AND SLOWLY PROGRESS
EASTWARD DURING THE WEEKEND...LIKELY ACROSS CENTRAL ILLINOIS. HIGH
AMOUNTS OF MOISTURE WILL ACCOMPANY THE SYSTEM AND PROVIDE THE
POTENTIAL FOR HEAVY RAINFALL RATES THAT OFTEN OCCUR WITH INLAND
TROPICAL SYSTEMS. THE PRECISE PATH OF THE SYSTEM REMNANTS REMAIN
HIGHLY UNCERTAIN...BUT THERE IS THE CHANCE FOR TOTAL RAINFALL
AMOUNTS BY LATE SUNDAY AT OR IN EXCESS OF TWO TO FIVE INCHES
ACROSS PARTS OF THE KANKAKEE AND VERMILION RIVER BASINS AND
SOUTHWARD. THIS INCLUDES THE IROQUOIS RIVER...AND INDIAN AND SUGAR
CREEKS.

WHILE CONDITIONS HAVE PRIMARILY BEEN DRY FOR MANY MONTHS AND MOST
STREAM FLOWS ARE BELOW NORMAL...THERE WAS RECENTLY HEAVY RAIN ON
AUGUST 26TH THAT MAY HAVE LOCALLY LOWERED THE GROUNDS WATER
CAPACITY. ALSO...IF HEAVY RAINFALL RATES WERE TO OCCUR...THESE CAN
LEAD TO FLASH FLOODING AND QUICK RISES ON SMALLER BASIN STREAMS AT
ANY TIME...EVEN WHEN EXPERIENCING PROLONGED DROUGHT.

THOSE WITH HYDROLOGIC INTERESTS SHOULD CONTINUE TO MONITOR
OUTLOOKS AND FORECAST RAINFALL AMOUNTS INTO THE HOLIDAY
WEEKEND AS THE FORECAST IS FURTHER REFINED.

UPDATED MONTHLY AROUND MID-MONTH. THESE OUTLOOKS ARE ISSUED IN
ADDITION TO THE 5 DAY RIVER FORECASTS THAT ARE ISSUED WHEN RIVER
FORECAST LOCATIONS ARE IN FLOOD OR FORECAST TO RISE ABOVE FLOOD
STAGE.

THIS LONG-RANGE PROBABILISTIC OUTLOOK CONTAINS FORECAST VALUES THAT
ARE CALCULATED USING MULTIPLE SEASON SCENARIOS FROM 30 OR MORE YEARS
OF CLIMATOLOGICAL DATA INCLUDING CURRENT CONDITIONS OF THE RIVER...
SOIL MOISTURE...AND 30 TO 90 DAY LONG-RANGE OUTLOOKS OF TEMPERATURE
AND PRECIPITATION.

BY PROVIDING THE COMPLETE RANGE OF PROBABILISTIC NUMBERS...THE LEVEL
OF RISK ASSOCIATED WITH LONG-RANGE PLANNING DECISIONS CAN BE
DETERMINED. THESE PROBABILISTIC FORECASTS ARE PART OF THE NATIONAL
WEATHER SERVICE ADVANCED HYDROLOGIC PREDICTION SERVICE.

PROBABILITY OF WATCH ISSUANCE...20 PERCENT

SUMMARY...CONVECTION IS INCREASING IN COVERAGE WITHIN BROAD/ELEVATED
WAA REGIME...FROM SRN/WRN IA TO CENTRAL WI. THIS TREND SHOULD
CONTINUE FOR ANOTHER 2-3 HOURS AS AREA OF TSTMS TRANSLATES EWD
ACROSS REMAINDER DISCUSSION AREA. SPORADIC LARGE HAIL WILL BE
PRIMARY CONCERN. ISOLATED GUSTS APCHG SVR LIMITS CANNOT BE RULED
OUT EITHER.

DISCUSSION...AT 08Z...SFC MESOANALYSIS SHOWED COLD FRONT ROUGHLY
FROM APOSTLE ISLANDS WI SWWD NEAR EAU...CCY...DSM...FNB..MHK LINE.
FRONT SHOULD CONTINUE TO MOVE ESEWD ACROSS THIS REGION 15-20 KT.
TSTMS HAVE DEVELOPED ON BOTH SIDES OF FRONT IN REGIME OF LOW-LEVEL
WAA ABOVE SFC. NARROW CORRIDOR OF PRECONVECTIVE MUCAPE NEAR COLD
FRONT WAS ESTIMATED AT AROUND 800 J/KG OVER NERN WI...INCREASING
WITH SWWD EXTENT TO 2000-2500 J/KG RANGE OVER SWRN IA IN ASSOCIATION
WITH GREATER MIDLEVEL LAPSE RATES. LLJ IS FCST TO
STRENGTHEN...RESULTING IN INCREASED MOISTURE
TRANSPORT/ADVECTION...BUT ALSO TO VEER WITH TIME. NET RESULT SHOULD
BE NEUTRAL TO SLGT DECREASING TREND IN STORM-RELATIVE INFLOW...BUT
ALSO HIGHER THETAE IN ELEVATED INFLOW LAYERS. EFFECTIVE SHEAR
MAGNITUDES 30-40 KT ARE EVIDENT OVER PARTS OF THIS AREA...WITH
VALUES STRONGLY DEPENDENT ON CHOSEN LIFTED PARCEL AND RESULTANT
DEPTH OF BUOYANT LAYER.

SFC AIR MASS ON BOTH SIDES OF FRONT WILL CONTINUE TO STABILIZE
DIABATICALLY FROM COMBINATION OF NOCTURNAL SFC COOLING AND PRECIP
INVOF TSTMS....WITH ADDITIONAL FACTOR OF CAA BEHIND FRONT. THAT
FACTOR WILL MITIGATE POTENTIAL FOR SVR GUSTS. HOWEVER...MODIFIED
RAOBS AND FCST SOUNDINGS SUGGEST LAYER OF DRYING BETWEEN SFC AND
BASE OF CAPE-BEARING LAYER AROUND 700 MB...IN SUPPORT OF DOWNDRAFT
MAINTENANCE.
