AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
645 AM CDT THU APR 10 2008

.DISCUSSION...

335 AM CDT

HEAVY RAIN AND SEVERE WEATHER POTENTIAL WILL CONTINUE TO BE THE
FOCUS OF THIS FORECAST. WILL NOT BE MAKING ANY CHANGES TONIGHT TO
GOING FLASH FLOOD WATCH HEADLINES FOR TODAY/TONIGHT.

STRONG LOW LEVEL THETA-E ADVECTION WILL CONTINUE TO SUPPORT THE
NORTHWARD EXPANSION OF RAIN ACROSS CENTRAL ILLINOIS INTO THE
FORECAST AREA EARLY THIS MORNING. INSTABILITY PROGS NOT OVERLY
IMPRESSIVE AND ANY CAPE IS QUITE ELEVATED TODAY THROUGH MID
AFTERNOON WITH SURFACE WARM FRONT ACROSS THE SOUTHERN PLAINS. SHORT
TERM NAM/RUC PROGS SEEM TO BE SUPPORTING CURRENT SITUATION WITH TWO
DISTINCT ENHANCED LOW LEVEL THETA-E GRADIENTS...THE FIRST ASSOCIATED
WITH INCREASING LOW LEVEL FLOW EARLY THIS MORNING ADVECTING MOISTURE
NORTHWARD INTO AN INITIALLY DRY AIR MASS...WITH ANOTHER LOW LEVEL
THETA-E GRADIENT FURTHER SOUTH ACROSS CENTRAL/SOUTHERN MISSOURI
ASSOCIATED WITH ELEVATED WARM FRONT. WHILE PRECIPITATION WILL BECOME
WIDESPREAD THIS MORNING...EXPECTING HEAVIER PRECIP TO OCCUR THIS
AFTERNOON ASSOCIATED WITH APPROACH OF THIS ELEVATED WARM FRONT. BY
THIS AFTERNOON MODEL FCST SOUNDINGS DO INDICATE SOME ELEVATED
INSTABILITY ON THE ORDER OF 200-400 J/KG WITH PRIMARY ELEVATED
INSTABILITY AXIS SETTING UP ACROSS WESTERN PORTIONS OF THE CWA.
SEVERE POTENTIAL DOES APPEAR TO BE LIMITED THROUGH MOST OF THE
AFTERNOON. HIGH TEMPERATURES THIS AFTERNOON WILL BE LIMITED BY
EXTENSIVE CLOUDS/PRECIP AND STIFF EASTERLY SURFACE FLOW NORTH OF THE
SURFACE WARM FRONT SHOULD KEEP TEMPS IN LOWER TO MID 40S ACROSS FAR
NORTHEAST ILLINOIS. DID GO AHEAD AND ALSO TRIM A FEW DEGREES OFF
HIGHS IN THE FAR SOUTH...WITH GENERALLY MID 50S EXPECTED.

HEAVY RAIN POTENTIAL WILL CONTINUE LATE THIS AFTERNOON INTO THIS
EVENING AS UPPER LEVEL FORCING BEGINS TO INCREASE IN RESPONSE TO
EASTWARD PROGRESSION OF STRONG UPPER LEVEL SYSTEM CURRENTLY ACROSS
THE CENTRAL ROCKIES. DISTINCT SHORT WAVE AND ASSOCIATED DRY
MID/UPPER PUNCH IS SHOWING UP NICELY ON WATER VAPOR EARLY THIS
MORNING ACROSS NORTH CENTRAL TEXAS AND THIS STRONG VORT MAX WILL BE
THE MAIN FEATURE TO MONITOR AS IT MOVES INTO THE MID MS VALLEY THIS
EVENING. IT STILL APPEARS AS THOUGH SURFACE WARM FRONT WILL REACH
FAR SOUTHERN PORTIONS OF THE CWA LATE THIS AFTERNOON TOWARD EVENING
AND REACHING INTO THE INTERSTATE 88 CORRIDOR TOWARD MIDNIGHT.
EXPECTING AN AXIS OF MODERATE INSTABILITY TO BE ASSOCIATED WITH THE
ADVANCING WARM FRONT WITH NAM/WRF MUCAPES MAXIMIZING INTO THE
1000-1500 J/KG RANGE ACROSS SOUTHEAST PORTIONS OF THE CWA THIS
EVENING AS INSTABILITY BECOMES PROGRESSIVELY MORE NEAR SFC BASED
ACROSS THE FAR SOUTH. GIVEN ABUNDANT AMOUNTS OF DEEP LAYER SHEAR AND
MODERATE INSTABILITY WILL HAVE TO MONITOR FOR POSSIBILITY OF
SUPERCELL DEVELOPMENT SOUTH OF THE WARM FRONT THIS EVENING...BUT
STILL EXPECTING PRIMARY MODE TO TRANSITION TO BOWING LINE SEGMENTS
LATE THIS EVENING AS STRONG SOUTHERN PLAINS VORT MAX LIFTS NORTHEAST
WITH STRONG AMBIENT WIND FIELD. GIVEN BEST INSTABILITY EXPECTED
MAINLY ACROSS SOUTHERN HALF OF CWA...SEVERE THREAT APPEARS TO BE
MAXIMIZED ACROSS THESE LOCATIONS. HOWEVER...ACROSS FAR NORTHERN
ILLINOIS WRF/NAM SUGGESTS SOME LOW LEVEL DEW POINT POOLING
ASSOCIATED WITH THE WARM FRONT AND INCREASING UPPER
DIFFLUENCE/DIVERGENCE. GIVEN SLIGHTLY LOWER FREEZING LEVELS ACROSS
THE NORTH AND STRONGER FORCING...PRIMARY SEVERE THREAT ACROSS THE
FAR NORTH MAY BE HAIL. PERHAPS OF GREATEST CONCERN TODAY WILL BE ON
THE POTENTIAL FOR HEAVY RAIN AND SIGNIFICANT FLOODING. WILL CONTINUE
TO FORECAST TOTAL RAINFALL AMOUNTS IN THE 1 TO 3 INCH
RANGE...ALTHOUGH LOCALIZED HIGHER AMOUNTS WILL BE POSSIBLE. IF THE
HIGHER END OF THIS FORECASTED RANGE DOES OCCUR...MODERATE/MAJOR
FLOODING WILL LIKELY OCCUR ACROSS MANY AREA RIVERS.

BY LATE TONIGHT...MAIN UPPER LEVEL SHORT WAVE IS EXPECTED TO EXIT
INTO NORTHWEST INDIANA WITH MID LEVEL DRY PUNCH SPREADING ACROSS THE
AREA. LATEST MODEL GUIDANCE CONTINUES TO SUGGEST THIS SHORT WAVE/DRY
PUNCH OUTRUNNING SFC COLD FRONT WITH THIS OCCLUDING SYSTEM...AND
MODEL
FORECAST SOUNDINGS SUGGESTS PERHAPS GREATEST INSTABILITY IN THE
09Z-15Z TIME FRAME JUST IN ADVANCE OF THE COLD FRONT. ONLY PROBLEM
WITH CONTINUED CONVECTIVE CHANCES INTO FRIDAY MORNING IS THAT
SYNOPTIC FORCING WILL BE QUITE A BIT WEAKER. HOWEVER...DID MAINTAIN
A CHANCE OF THUNDER EARLY FRIDAY MORNING ACROSS MAINLY NORTHWEST
INDIANA UNTIL FRONT CLEARS THE AREA. TEMPS WILL HAVE A NON DIURNAL
NATURE THROUGH TONIGHT...WITH RISING TEMPS TONIGHT WITH THE WARM
FRONT...AND THEN FALLING TEMPS FRIDAY AFTERNOON BEHIND THE COLD
FRONT.

UPPER LEVEL LOW WILL BE SLOW TO EXIT THE GREAT LAKES REGION INTO THE
WEEKEND WITH A CONTINUED CHANCE OF RAIN SHOWERS THROUGH SATURDAY.
PERHAPS BEST CHANCE OF PRECIP WILL BE LATER SATURDAY AS SECONDARY
TROUGH/REINFORCING COLD SHOT DROPS INTO THE AREA. WOULD NOT EVEN
COMPLETELY BE SURPRISED TO SOME LAKE EFFECT SNOW SHOWERS SATURDAY
NIGHT WITH MARGINAL THERMODYNAMIC SUPPORT. HOWEVER...EXPECTING
GENERALLY LITTLE OR NO ACCUMS AT THIS TIME. LATEST 00Z MODELS
SUGGEST PERHAPS A SLOWING TO MODERATING TREND EARLY NEXT WEEK DUE TO
PHASING OF EASTERN CANADIAN AND WESTERN GREAT LAKES UPPER LOW...BUT
BY WEDNESDAY TEMPS MAY REACH BACK WELL INTO THE 60S AS AMPLIFIED
UPPER RIDGE AXIS APPROACHES THE AREA.

IT WILL BEGIN TO WEAKEN...EVENTUALLY REACHING NEW ENGLAND
SATURDAY AND SATURDAY NIGHT.

TIGHTENING OF THE SURFACE PRESSURE GRADIENT AS THIS LOW APPROACHES
