AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LINCOLN IL
548 AM CST SUN FEB 27 2011

.DISCUSSION...
ISSUED 314 AM CST SUN FEB 27 2011

MAIN CONCERN WITH THIS FORECAST PACKAGE WILL BE SEVERE/HEAVY RAIN
POTENTIAL TONIGHT...AS VIGOROUS STORM SYSTEM TRACKS THROUGH THE AREA.

08Z SURFACE CHART SHOWS LOW PRESSURE DEVELOPING OVER EASTERN
COLORADO...WHILE A WELL-DEFINED BAROCLINIC ZONE EXTENDS E/SE FROM
THE LOW ACROSS THE SOUTHERN PLAINS INTO THE TENNESSEE RIVER VALLEY.
IMPRESSIVE TEMPERATURE GRADIENT NOTED ACROSS THIS BOUNDARY...WITH
50S/60S TO THE SOUTH ACROSS THE SOUTHERN PLAINS AND TEENS/20S TO THE
NORTH. ALOFT...CLOSED LOW IS BEGINNING TO EJECT EASTWARD ACROSS
SOUTHERN CALIFORNIA.

SHORT TERM...TODAY THROUGH TUESDAY

AS UPPER LOW TRACKS EASTWARD TODAY...SURFACE LOW WILL DEEPEN AND
BEGIN LIFTING E/NE TOWARD ILLINOIS. INCREASING SOUTHERLY FLOW
AHEAD OF THE SYSTEM WILL PUSH STRONG FRONTAL BOUNDARY
NORTHWARD...EVENTUALLY REACHING CENTRAL ILLINOIS BY THIS
AFTERNOON. MODELS CONTINUE TO INDICATE AN AREA OF STRONG FORCING
DEVELOPING ALONG THE ADVANCING FRONT LATER THIS MORNING...RESULTING
IN A RAPID DEVELOPMENT OF SHOWERS/ISOLATED THUNDER ACROSS CENTRAL
MISSOURI. SHOWERS WILL TRACK NORTHEASTWARD INTO WEST-CENTRAL
ILLINOIS TOWARD MIDDAY...THEN WILL SPREAD FURTHER E/NE DURING THE
AFTERNOON. WITH BEST LIFT/MOISTURE REMAINING TO THE W/SW EARLY IN
THE DAY...WILL GO WITH A DRY FORECAST ACROSS THE BOARD THIS
MORNING...FOLLOWED BY INCREASING POPS DURING THE AFTERNOON. BASED ON
EXPECTED CONVECTIVE DEVELOPMENT ACROSS CENTRAL MISSOURI AS NOTED
ON THE NAM-WRF AND 4KM WRF-NMM...HAVE HIT POPS HARDEST ALONG AND
NORTHWEST OF THE I-55 CORRIDOR. WITH WARM FRONT LIFTING NORTHWARD
INTO THE AREA...A TIGHT THERMAL GRADIENT WILL BE SEEN ACROSS THE
KILX CWA TODAY. HIGH TEMPS WILL HOVER IN THE UPPER 30S NORTHWEST
OF THE ILLINOIS RIVER AROUND GALESBURG...BUT WILL SOAR TO AROUND
60 DEGREES SOUTH OF I-70.

HIGHLY DYNAMIC SYSTEM WILL SWING THROUGH THE MIDWEST
TONIGHT...BRINGING A ROUND OF POTENTIALLY SEVERE THUNDERSTORMS TO
PARTS OF THE REGION. COUPLED JET STRUCTURE WILL AID IN SYNOPTIC
LIFT...AS CENTRAL ILLINOIS WILL BE POSITIONED IN THE RIGHT
ENTRANCE REGION OF A 300MB JET STREAK ACROSS THE EASTERN GREAT
LAKES AND THE LEFT EXIT REGION OF A JET RACING ACROSS THE SOUTHERN
PLAINS. AT LOWER-LEVELS...A STRONG 60KT 850MB JET STREAK WILL
DEVELOP FROM THE LOWER MISSISSIPPI RIVER VALLEY N/NE INTO EAST-CENTRAL
ILLINOIS. END RESULT WILL BE A HIGHLY SHEARED ENVIRONMENT...WITH
0-3KM STORM RELATIVE HELICITY VALUES IN THE 500 TO 700 RANGE.
SURFACE LOW TRACK WILL BISECT THE KILX CWA TONIGHT...PLACING
EAST-CENTRAL AND SOUTHEAST ILLINOIS IN THE WARM SECTOR OF THE
SYSTEM. GIVEN HEALTHY SURFACE-BASED INSTABILITY PARAMETERS AND
VERY HIGH SHEAR...THINK STRONG TO SEVERE THUNDERSTORMS WILL BE A
GOOD BET EAST OF I-55 BETWEEN 7 PM AND 3 AM. HAVE THEREFORE INCLUDED
MENTION OF POSSIBLE SEVERE ACROSS THE E/SE ZONES TONIGHT. FURTHER
NORTHWEST INTO THE COLDER AIR...SEVERE CHANCES DECREASE
SUBSTANTIALLY ACROSS THE ILLINOIS RIVER VALLEY.

IN ADDITION TO THE SEVERE WEATHER POTENTIAL...HEAVY RAINFALL WILL
BE A THREAT AS WELL. RAINFALL AMOUNTS WILL GENERALLY RANGE FROM 1
TO 1.50 INCHES ACROSS THE AREA...BUT COULD BE LOCALLY HIGHER
WITHIN THUNDERSTORMS. FLASH FLOOD GUIDANCE IS AOA 2 INCHES...SO
WIDESPREAD FLOODING IS NOT ANTICIPATED. HOWEVER...GIVEN HIGH
RAINFALL RATES AND SATURATED SOIL...WOULD NOT BE SURPRISED TO SEE
A FEW REPORTS OF FLASH-FLOODING...PARTICULARLY IN URBAN AREAS
WHERE STORM DRAINS MAY BE CLOGGED WITH LEAVES AND DEBRIS. HAVE
ISSUED A HYDROLOGIC OUTLOOK TO HIGHLIGHT THREAT...AND WILL ALLOW
DAY SHIFT TO MAKE THE FINAL ASSESSMENT ON WHETHER A FLOOD WATCH IS
NEEDED.

AFTER SOME LINGERING SHOWERS MONDAY MORNING...COLDER/DRIER WEATHER
WILL ARRIVE BY AFTERNOON AS STORM SYSTEM QUICKLY PULLS AWAY FROM
THE AREA. HIGH PRESSURE WILL ENSURE ANOTHER DRY DAY ON
TUESDAY...WITH MODERATING TEMPS.

LONG TERM...WEDNESDAY THROUGH SATURDAY

QUIET WEATHER WILL BE THE RULE WEDNESDAY AND THURSDAY...BEFORE
THE NEXT SIGNIFICANT SYSTEM ARRIVES BY THURSDAY NIGHT INTO FRIDAY.
GFS/ECMWF/CANADIAN ALL IN GOOD AGREEMENT WITH THE TIMING OF THE
SYSTEM AND WITH THERMAL PROFILES SUPPORTING ALL RAIN. CURRENT
FORECAST HANDLES THE LATE WEEK SITUATION QUITE WELL...SO MADE NO
CHANGES BEYOND THURSDAY.

.AVIATION...
ISSUED 548 AM CST SUN FEB 27 2011

PREDOMINANTLY IFR CONDITIONS ANTICIPATED THROUGH THE 12Z TAF VALID
TIME...THOUGH MVFR CONDITIONS ARE POSSIBLE FOR A FEW HOURS THIS
MORNING. PLENTY OF LOW LEVEL MOISTURE REMAINS OVER THE REGION TO
START TODAY. SOUTHEASTERLY WINDS WILL DEVELOP AS A STORM SYSTEM
APPROACHES...WITH A STRONG LOW LEVEL INVERSION ACTING TO TRAP THE
MOISTURE MORE STRONGLY THAN IT IS AT THE MOMENT. THE LOW
ASSOCIATED WITH THE STORM SYSTEM IS FORECAST TO TRACK THROUGH
CENTRAL ILLINOIS TONIGHT...WHICH SHOULD RESULT IN CONSIDERABLE
WIND DIRECTION CHANGES. THE APPROACH OF THE SYSTEM WILL ALSO
RESULT IN SHOWERS AND SCATTERED THUNDERSTORMS BREAKING OUT AS
EARLY AS LATE AFTERNOON. ONCE THE PRECIPITATION SPREADS INTO THE
REGION...IT SHOULD PREVAIL THROUGH THE BALANCE OF THE TAF VALID
TIME. WHILE THUNDERSTORMS WILL BE AROUND...HAVE ONLY GONE WITH A
VCTS MENTION IN THE TERMINALS DUE TO THE CONSIDERABLE UNCERTAINTY
IN SPECIFIC TIMING AND LOCATION OF THE STORMS.
