AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
300 PM CDT THU OCT 20 2011

.DISCUSSION...
1209 PM CDT

PRELIMINARY SHORT TERM DISCUSSION FOR THIS AFTERNOON THROUGH SAT
NIGHT...

THE UPPER LOW CENTER OF CIRCULATION WAS OVER LAKE ERIE AT MIDDAY AND
LIFTING TO THE NNE. SHORT RANGE MODEL OUTPUT HAS A GOOD HANDLE ON
THIS MOVEMENT AND CONTINUE TO LIFT THE UPPER LOW NNE-NE TO CENTRAL
QUEBEC BY 12Z FRI. WITH THE SYSTEM MOVING OFF TO THE NNE AND NE THE
REST OF TODAY AND THROUGH THE NIGHT THE BACK EDGE OF THE RAIN THAT
HAS BEEN SLOWLY ERODING/BREAKING UP OVER EASTERN WI AND NE IL AS
DRIER MID LEVEL AIR PER 12Z RAOBS...700HPA DEW POINT DEPRESSION OF
7C AT KMPX AND 12C AT KINL...GETS ENTRAINED INTO THE WEST SECTOR OF
THE GREAT LAKES SYSTEM.

THIS TREND WILL CONTINUE THE REST OF THE DAY AND BY THIS EVENING THE
WEST EDGE OF ANY SIGNIFICANT THREAT OF RAIN WILL HAVE SHIFTED OUT
OVER LAKE MI.  ONLY EXCEPTION WILL BE PORTER COUNTY OF FAR NW IN
WHERE FORECAST THERMAL PROFILE STILL SUPPORTIVE OF LAKE EFFECT RAIN
BUT CLOUD BEARING LAYER FLOW FROM THE NNW-NW KEEPS MOST OF THE
REMAINING LAKE EFFECT MORE TOWARD N CENTRAL IN AND SW LOWER MI.

WITH THE WEAKENING OF THE LOW LEVEL PRESSURE GRADIENT CONTINUING
THIS AFTERNOON WINDS WILL CORRESPONDINGLY GRADUALLY DIMINISH
THOUGH REMAIN BREEZY.

MODELS SHOW THE SHORT WAVE TROUGH OVER GRB AT MIDDAY DROPPING S-SSE
AND CROSSING SE WI...NW IL AND NW IN OVERNIGHT. WHILE CONTINUED
DRYING OF LOWER AND MID WILL BE OCCURRING...THE SHORT WAVE TROUGH
WILL BRING SOME HIGH CLOUDINESS ACROSS THE LOCAL FORECAST AREA. HIGH
CLOUDS WILL CLEAR DURING OVERNIGHT BEFORE SUNRISE ALLOWING FOR
RADIATIONAL COOLING THUS THREAT OF FROST FOR EARLY MORNING FRI
REMAINS ACROSS THE WESTERN PORTIONS OF THE FORECAST AREA WHERE
COLDER TEMPERATURES AND LIGHTER WINDS WILL BE.

WITH THE UPPER LOW CONTINUING TO MOVE EVEN FARTHER AWAY FRI RIDGING
BUILDS FROM THE MID MO AND UPPER MS VALLEYS OVER THE UPPER MIDWEST
AND WESTERN GREAT LAKES. THIS WILL RESULT IN CLEAR SKIES AND A BIT
OF MODERATION IN TEMPERATURES FRI.

A SHORT WAVE IS PROGGED TO MOVE ESE FROM TO NORTHERN PLAINS TO THE
UPPER MIDWEST FRI NIGHT AND SAT. THIS SYSTEM WILL BE MOISTURE
STARVED WITH ONLY AN INCREASE IN HIGH AND SOME MID LEVEL CLOUDINESS.
THE SHORT WAVE DOES EVENTUALLY PUSH A COLD FRONT ACROSS INTO THE
LOCAL AREA SAT NIGHT WITH MODERATELY STRONG LOW LEVEL WARM AIR
ADVECTION OCCURRING AHEAD OF THE FRONT DURING SAT AS THE FLOW BACKS
TO SOUTHWESTERLY AHEAD OF THE APPROACHING SHORT WAVE TROUGH AND
ASSOCIATED COLD FRONT. THIS WARMING COMBINED WITH MAINLY SUNNY SKIES
AT LEAST FOR THE FIRST HALF OF THE DAY SHOULD ALLOW AFTERNOON
TEMPERATURES TO REACH FROM THE UPPER 50S TO THE MID 60S ACROSS THE
AREA.

  AFTERNOON/EVENING.

KJB

//DISCUSSION...UPDATED 18Z...

LOW PRESSURE ACROSS THE EASTERN GREAT LAKES WILL CONTINUE TO LOSS
ITS GRIP ON NORTHERN ILLINOIS AND NORTHWEST INDIANA AS IT MOVES
NORTHEAST THROUGH QUEBEC TONIGHT. HOWEVER...GUSTY NORTHWEST WINDS UP
TO 25 KT WILL CONTINUE THOROUGH MUCH OF THE AFTERNOON...BEFORE THE
WINDS ABATE THIS EVENING. CIGS SHOULD ALSO BE IMPROVING TO LOW END
VFR LATER THIS AFTERNOON AND SKIES SHOULD BECOME MOSTLY CLEAR
OVERNIGHT. A SURFACE RIDGE OF HIGH PRESSURE WILL BUILD IN ACROSS THE
AREA FOR FRIDAY. THIS SHOULD PRODUCE LIGHT WESTERLY FLOW ACROSS THE
TERMINALS.

.MARINE...
155 PM CDT

WINDS WILL CONTINUE TO GRADUALLY DIMINISH ACROSS LAKE MICHIGAN
THROUGH TONIGHT...AS DEEP LOW PRESSURE LIFTS TO THE NORTHEAST ALONG
THE EAST SHORE OF LAKE HURON AND INTO EASTERN ONTARIO.

EARLY AFTERNOON OBSERVATIONS AROUND THE LAKE INDICATE WINDS HAVE
EASED INTO THE 35-40 KT RANGE FOR THE MOST PART...THOUGH STILL A FEW
GUSTS INTO THE MID 40S AROUND SOUTH HAVEN MICHIGAN. BASED ON THIS...
AND THE EXPECTED TREND OF GRADUALLY DIMINISHING WINDS...WILL GO
AHEAD AND LET THE STORM WARNING END FOR THE OPEN WATERS AND INDIANA
NEAR SHORE ZONES...REPLACING THESE HEADLINES WITH A GALE WARNING
WHICH WILL CONTINUE THROUGH 06Z/1 AM CDT. WINDS MAY FALL BELOW GALE
A BIT EARLIER...BUT PREFER TO HAVE TO CANCEL EARLY RATHER THAN
EXTEND GALE HEADLINES LATER THIS EVENING. WINDS WILL CONTINUE TO
SLACKEN ON FRIDAY...AS THE LOW PULLS AWAY AND FILLS AND WEAK HIGH
PRESSURE RIDGING MOVES INTO THE WESTERN LAKES.

FOR THE ILLINOIS NEARSHORE AREAS...WILL MAINTAIN GALE WARNING
THROUGH 00Z/7 PM CDT WHICH WILL THEN ALLOW DOWNGRADE TO A SMALL
CRAFT ADVISORY AT THAT TIME.

LATER IN THE FORECAST PERIOD...A COUPLE OF TRANSIENT LOW PRESSURE
SYSTEMS WILL AFFECT THE REGION. ONE WEAKER LOW IS EXPECTED TO PASS
ACROSS THE NORTHERN LAKES ON SUNDAY...AND IS PROGGED TO DEEPEN
SLIGHTLY AS IT MOVES OFF TO THE EAST MONDAY. THIS WILL LIKELY
PRODUCE A RELATIVELY SHORT PERIOD OF GUSTY WEST WINDS AROUND 25 KTS.
A SECOND LOW PRESSURE SYSTEM IS EXPECTED TO DEVELOP LATE TUESDAY AND
WEDNESDAY ACROSS REGION. MODEL FORECASTS EXHIBIT QUITE A BIT OF
SPREAD IN LOCATION/STRENGTH AT THIS TIME...SO HAVE STAYED WITH
BLENDED GUIDANCE SOLUTION WHICH MAY ULTIMATELY END UP BEING TOO LOW
WITH WIND SPEEDS. THIS WILL BE MONITORED FOR MORE DETAIL AS FURTHER
MODEL RUNS GET A BETTER HANDLE ON THIS SYSTEM FOR THE MIDDLE OF NEXT
WEEK.
