AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
656 AM CDT THU OCT 18 2007

.DISCUSSION...
345 AM CDT

FORECAST FOCUS CONTINUES TO CENTER ON POTENTIAL OF SEVERE WEATHER
TODAY AND WINDS. MOST OF THE FORECAST AREA REMAINS UNDER A MODERATE
RISK OF SEVERE THUNDERSTORMS TODAY.

UPPER FORCING HAS BEEN STEADILY ON THE INCREASE OVERNIGHT WITH
INCREASING UPPER DIFFLUENCE DOWNSTREAM OF UPPER LOW CENTERED ACROSS
EASTERN NEBRASKA. LOW PRESSURE CONTINUES TO DEEPEN AS IT TRACKS INTO
EASTERN NEBRASKA THIS MORNING...WITH BROAD AREA OF STRONG SFC
PRESSURE FALLS CENTERED ACROSS WESTERN WISCONSIN IN AREA OF MAX LOW
LEVEL WARM ADVECTION. TIGHTENING SURFACE PRESSURE GRADIENT IN
COMBINATION WITH THESE PRESSURE FALLS TO THE NORTHWEST AS ALLOWED
FOR SOME STRONG WINDS GUSTING TO 25 TO 30 KNOTS OVERNIGHT. FIRST
LARGE AREA OF RAIN/ISOLATED THUNDER CONTINUES TO LIFT ACROSS FAR
NORTHERN ILLINOIS INTO MUCH OF NORTHWEST INDIANA. ANOTHER AREA OF
SHOWERS AND THUNDERSTORMS IS TRACKING THROUGH WEST CENTRAL ILLINOIS
AND HAS REACHED A KEWANEE TO PEORIA TO CHARLESTON LINE AT APPROX 08Z
THIS MORNING. THIS PRECIPITATION IS IN ASSOCIATION WITH A FAIRLY
STRONG UPPER LEVEL VORT MAX MOVING THROUGH CENTRAL MISSOURI. AMBIENT
WINDS QUITE STRONG RESULTING IN CELL MOVEMENTS OF 50 KNOTS OR SO
WITH THE SHOWERS IN WEST CENTRAL ILLINOIS AND EXPECTING THESE
SHOWERS/SCT TSTROMS TO MOVE THROUGH NORTHERN ILLINOIS THROUGH THE
13Z TIME FRAME.

BY MID MORNING...IT STILL APPEARS AS THOUGH A MID LEVEL DRY SLOT
WILL BEGIN TO PUNCH INTO THE FORECAST AREA WITH FAIRLY STRONG
FORCING FOR DESCENT LATER THIS MORNING INTO EARLY THIS AFTERNOON.
THE SHOWERS MOVING THROUGH THIS MORNING MAY POSE A LOWER COVERAGE
MARGINAL WIND THREAT...BUT MAIN SEVERE THREAT AT THIS TIME APPEARS
TO BE FOR LATER THIS AFTERNOON AS ANOTHER VORT MAX/UPPER LEVEL JET
STREAK ROUNDS THE BASE OF THE UPPER TROUGH AND NOSES INTO THE
SOUTHERN GREAT LAKES REGION. SOME SUBTLE DIFFERENCES STILL EXIST
BETWEEN NAM/GFS SOLUTIONS REGARDING TIMING OF COLD FRONT ACROSS THE
AREA BUT OVERALL MODELS ARE IN FAIRLY GOOD AGREEMENT TAKING COLD
FRONT INTO FAR NORTHEAST ILLINOIS BY LATE THIS AFTERNOON. HAVE TRIED
TO INDICATE DIMINISHING TREND IN PRECIP THIS MORNING...AND THEN
THUNDERSTORMS BECOMING LIKELY AGAIN LATER THIS AFTERNOON (ESPECIALLY
AFTER 20-21Z AS UPPER JET STREAK NOSES INTO CENTRAL
ILLINOIS/NORTHWEST INDIANA. SEVERE PARAMETERS STILL LOOKING QUITE
IMPRESSIVE. MLCAPES ON THE ORDER OF 1200 J/KG STILL BEING INDICATED
IN WRF FORECAST SOUNDINGS WITH DEEP LAYER SHEAR MAGS ON THE ORDER OF
70 KNOTS AND LOW LEVEL 0 TO 1 KM SHEAR AROUND 30 KNOTS THIS
AFTERNOON. PRESENCE OF MID LEVEL DRY SLOT ATOP UNSEASONABLY MOIST
LOW LEVEL AIR MAY ALSO ENHANCE LOW AND MID LEVEL LAPSE
RATES/INSTABILITY VIA DIFFERENTIAL LAYER COOLING ONCE SYNOPTIC
FORCING BECOMES MORE PRONOUNCED THIS AFTERNOON. LCLS APPEAR TO BE
RATHER LOW THIS AFTERNOON GIVEN DEW PTS IN THE LOWER 60S AND SFC
TEMPS IN THE 70S. MAY BE SOME DISCRETE CELLS DEVELOPMENT BRIEFLY
LATER THIS AFTERNOON WITH POTENTIAL FOR THESE TO RAPIDLY BECOME
SUPERCELLULAR GIVEN THE ABOVE FAVORABLE PARAMETERS...ALTHOUGH
EXPECTING CONVECTION TO TRANSITION TO A LINEAR MODE LATE THIS
AFTERNOON/EARLY EVENING INTO NORTHWEST INDIANA WITH EMBEDDED
SUPERCELLULAR STRUCTURE. IN ADDITION TO LARGE HAIL AND DAMAGING
WINDS...ISOLATED TORNADO THREAT WILL EXIST ESPECIALLY LATE AFTERNOON
WHEN MORE DISCRETE DEVELOPMENT IS POSSIBLE. SPC HAS SHIFTED MODERATE
RISK OF SEVERE SLIGHTLY EASTWARD...GENERALLY EAST OF A BELVIDERE TO
OTTAWA TO PONTIAC LINE. THIS SEEMS REASONABLE GIVEN EXPECTED FRONTAL
TIMING AND PROXMITY OF BEST UPPER FORCING THIS AFTERNOON ACROSS
EASTERN PORTIONS OF THE CWA.

OTHER CONCERN FOR TODAY IS WINDS...STEEP LOW LEVEL LAPSE RATES THIS
AFTERNOON SHOULD PROMOTE GUSTS TO NEAR ADVISORY LEVEL CRITERIA THIS
AFTERNOON. HAVE OPTED AT THIS TIME TO BRING WINDS TO NEAR ADVISORY
CRITERIA BUT WILL HOLD OFF ANY WIND HEADLINES AT THIS TIME.
OTHERWISE...UNSEASONABLY WARM TEMPS TODAY IN THE MID TO UPPER
70S...WITH SOME LOWER 80S EVEN POSSIBLE ACROSS THE FAR SOUTH. BY
TONIGHT...SECONDARY TROUGH MOVING THROUGH THE AREA MAY ALLOW FOR
SOME SCT SHOWERS TO LINGER THROUGH THE EVENING...AND WILL HAVE TO
MAINTAIN CHANCE POPS FOR SHOWERS INTO FRIDAY AS UPPER LOW IS SLOW TO
MOVE THROUGH THE GREAT LAKES REGION. ANOTHER QUITE WINDY DAY IN
STORE FOR FRIDAY WITH TEMPS BACK CLOSER TO SEASONABLE NORMALS AND
CLOUDY SKIES.

NO SIGNIFICANT CHANGES WERE MADE TO THE REMAINDER OF THE FORECAST
WITH SKIES CLEARING OUT FRIDAY EVENING...AND THEN A WARMING TREND
FOR THE WEEKEND AS BROAD UPPER RIDGING MOVES INTO THE REGION IN
ADVANCE OF NEXT AMPLIFIED TROUGH WHICH WILL BRING NEXT CHANCE OF
SHOWERS EARLY NEXT WEEK.

.AVIATION...

656 AM CDT

WATER VAPOR IMAGERY AND PROFLIER DATA INDICATE NEGATIVE TILT SHORT
WAVE TROUGH LIFTING NORTHEAST ACROSS IOWA/ILLINOIS. IMPRESSIVE DRY
SLOT PUNCHING IN BEHIND TROUGH AXIS...WITH TIMING OFF RADAR/SAT
LOOPS INDICATING TRAILING EDGE OF SHOWERS TO LIFT THROUGH TERMINALS
SHORTLY SO WILL JUST HAVE ABOUT 1 HOUR TEMPO FOR SOME LIGHT SHOWERS
AND SCATTERED LOWER CLOUDS...THEN PERIOD OF VFR CONDITIONS AS DRY
SLOT ADVANCES NORTHEAST ACROSS THE FORECAST AREA THROUGH MID
MORNING. LOW LEVELS FAIRLY MOIST WITH SFC DEW POINTS IN THE 60S SO
EXPECT WILL SEE SOME CU DEVELOPMENT BENEATH MID LEVEL DRY SLOT BY
LATE MORNING. ATTENTION THEN TURNS TO POTENTIAL REDEVELOPMENT OF
CONVECTION THIS AFTERNOON. SHORT TERM PROGS FROM VARIOUS MODEL
GUIDANCE REMAIN IN DECENT AGREEMENT WITH DEEP SURFACE LOW MOVING
FROM EASTERN NEBRASKA TO NORTHWEST WISCONSIN BY EVENING. SURFACE
COLD FRONT/OCCLUSION EXTENDING SOUTHEAST FROM THIS LOW FORECAST TO
PUSH ACROSS FORECAST AREA DURING AFTERNOON HOURS...WITH MOIST LOW
LEVEL BOUNDARY LAYER CONTRIBUTING TO MLCAPE VALUES IN 1500-2000 J/KG
RANGE BY 20Z OR SO PER WRF FORECAST SOUNDINGS. APPEARS THERE WILL BE
SHORT WINDOW OF TIME THIS AFTERNOON BEFORE FRONT PUSHES THROUGH FOR
DEVELOPMENT OF CONVECTION AND HAVE GONE WITH TEMPO MID AFTN BEFORE
CONVECTION THEN MOVES RAPIDLY OFF TO EAST/NORTHEAST. SECONDARY SHORT
WAVE THEN MOVES THROUGH OVERNIGHT WITH SFC TROUGH AND ADDITIONAL
SHOWER CHANCES WITH MVFR CIGS EXPECTED.

WINDS ALSO SIGNIFICANT ISSUE TODAY. STRONG SOUTHEAST WINDS GUSTING
NEAR 30 KNOTS EARLY THIS MORNING SHOULD EASE A BIT THIS MORNING AS
STRONG PRESSURE FALLS PROPAGATE NORTH AHEAD OF MORNING SHORT WAVE.
GRADIENT WILL REMAIN TIGHT HOWEVER WITH DEEP LOW OFF TO THE
WEST/NORTHWEST WITH SOUTH WINDS EXPECTED TO BE GUSTING NEAR 30 KNOTS
AGAIN BY AFTERNOON AS NEXT SPEED MAX/WAVE APPROACH. GRADUAL SHIFT TO
SOUTHWEST WITH GUSTS FALLING BACK INTO 20-25 KNOT RANGE THIS
EVENING...THEN MORE WSW AFTER MIDNIGHT.

RATZER

.MARINE...

345 AM CDT

INTENSE LOW PRESSURE OVER EASTERN NEBRASKA WILL CONTINUE TO LIFT
NORTHEAST TOWARD WESTERN LAKE SUPERIOR THROUGH TODAY. STRONG
PRESSURE FALLS AND TIGHTENING OF SURFACE PRESSURE GRADIENT WILL
RESULT IN SOUTHEAST/SOUTH WINDS OF GALE FORCE TODAY. AS THE LOW
LIFTS THROUGH NORTHERN LAKES TONIGHT...WINDS EXPECTED TO EASE BELOW
GALE FORCE...BUT PRESSURE GRADIENT OF LOW WILL CONTINUE TO AFFECT
WESTERN LAKES NEXT 48 HOURS. SECONDARY TROUGH PUSHING ACROSS LAKE
MICHIGAN EARLY FRIDAY WILL SHIFT WINDS TO MORE WEST/SOUTHWEST WITH
LOW LEVEL COLD ADVECTION HELPING TO MAXIMIZE WIND SPEEDS AROUND 30
KNOTS WITH SOME GALE FORCE GUSTS NOT OUT OF THE QUESTION.

LOW FINALLY PULLS AWAY ACROSS HUDSON BAY FRIDAY NIGHT/SATURDAY
ALLOWING WINDS TO SLACKEN...AS WEAK HIGH PRESSURE RIDGE MOVES INTO
WESTERN LAKES. NEXT TROUGH ALREADY EXPECTED TO DEVELOP ACROSS PLAINS
HOWEVER...WITH SOUTHWEST WINDS ON BACK SIDE OF WEAK RIDGE
STRENGTHENING SATURDAY NIGHT/SUNDAY.
