AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
512 AM CDT THU MAY 26 2011

.DISCUSSION...
332 AM CDT

TODAY...
POTENT UPPER LEVEL SHORTWAVE CENTERED EARLY THIS MORNING OVER
CENTRAL ILLINOIS CONTINUES TO DRIFT EAST. ACROSS THE NORTHERN
PERIPHERY OF THIS SHORTWAVE AN AREA OF DEFORMATION
PRECIPITATION...STRETCHING ACROSS WEST CENTRAL ILLINOIS NORTHEAST
THROUGH SOUTHERN LAKE MICHIGAN. ANTI-CYCLONIC FLOW CENTERED OVER
MANITOBA/WESTERN ONTARIO...WAS BEGINNING TO BUILD INTO THE UPPER
MIDWEST PROVIDING MUCH DRIER/COOLER AIR. THE COMBINATION OF THE
ANTI-CYCLONIC FLOW TO THE NORTH AND POTENT UPPER LEVEL SHORTWAVE TO
THE SOUTH...HAS ALLOWED A TIGHT PRESSURE GRADIENT TO OCCUR OVER
NORTHERN IL/SOUTHERN WI...WITH BREEZY CONDITIONS AT THE SURFACE FROM
THE NORTHEAST.

PRECIPITATION WILL STEADILY COME TO AN END LATER TODAY...HOWEVER
DURING THE FIRST HALF OF THE MORNING NORTHERN IL WILL CONTINUE TO BE
UNDER THE INFLUENCE OF A DEPARTING DEFORMATION ZONE. THUS EXPECT
SHOWERS TO PERSIST...RAPIDLY DECLINING WITH BETTER MIXING AND
MID-LVL SUBSIDENCE ARRIVING IN THE AFTERNOON HOURS.

MUCH COOLER AIR IS SLIDING SOUTHWEST ACROSS THE STRAITS OF
MACKINAW...ACROSS LAKE MICHIGAN TOWARDS NORTHERN IL. THIS COMBINED
WITH CONSIDERABLE SOLAR SHIELDING THROUGH MIDDAY WILL LIMIT SURFACE
HEATING...THUS EXPECT TEMPS TO REMAIN WELL BELOW NORMAL WITH HIGHS
MAINLY IN THE LOW/MID 50S. CLOSER TO LAKE MICHIGAN TEMPERATURES WILL
BE UNDER THE COOLER MARINE ENVIRONMENT...AND MAY HOLD TEMPERATURES
TO AROUND 50 DEGREES. A FEW LOCATIONS MAY STRUGGLE TO WARM ABOVE THE
UPPER 40S.

TONIGHT THROUGH FRIDAY...
500MB TROUGH CONTINUES TO PIVOT EAST WITH DIFLUENT FLOW ALOFT AND
GOOD MIXING IN THE LATE AFTERNOON/EVENING HOURS...EXPECT SKY COVER
TO THIN. THERMAL TROUGH AT 850MB BASED ON NAM/LOCAL WRF INDICATE
TEMPS AT 850MB OF 3 TO 5 DEG C ACROSS THE NORTHWEST PORTIONS OF THE
CWFA...SLIGHTLY WARMER FURTHER SOUTHEAST. ALTHOUGH IT APPEARS DRY
WEATHER WILL DEVELOP FOR TONIGHT...THE PRESENCE OF ANTI-CYCLONIC
FLOW AND MINIMAL PRESSURE GRADIENT SHOULD KEEP WINDS MINIMAL.
ALTHOUGH IT DOES NOT APPEAR WINDS GO COMPLETELY CALM...THEY DO
DECOUPLE TO LESS THAN 10KT. THUS EXPECT RADIATIONAL COOLING TO BE
MAXIMIZED...AND ALLOW TEMPS TO BOTTOM OUT EARLY FRI IN THE UPR 30S
NORTH OF I-88 AND WEST OF LAKE MICHIGAN. THIS ARE COULD SEE SOME
PATCHY FROST DEVELOP AFTER MIDNIGHT. ELSEWHERE TEMPERATURES WILL
COOL INTO THE LOW/MID 40S.

MID-LVL HEIGHTS INCREASE THROUGHOUT FRI AFTN/EVE...WITH DRY AIR IN
THE BOUNDARY LAYER. IT APPEARS A LULL IN THE WEATHER SYSTEMS WILL
CONTINUE THROUGH MUCH OF THE DAY FRI...AS A UPPER LEVEL VORT PUSHES
INTO THE NORTHERN PLAINS. THIS FEATURE HAS UNDERGONE SUBSTANTIAL
ADJUSTMENTS WITH RESPECT TO THE PLACEMENT OF THE UPPER LEVEL
FEATURE. IT NOW APPEARS GUIDANCE BRINGS THIS FEATURE INTO THE UPPER
PLAINS. ONE OF THE DRIVERS FOR THE FURTHER NORTH PATH IS THE
DOWNSTREAM RIDGE THAT CONTINUES TO BE OVER THE CANADIAN
MARITIME...SLOWING THE PROGRESSIVE NATURE OF WEATHER SYSTEMS IN THE
MID-LATITUDES.

THIS DOWNSTREAM RIDGE WILL BE A KEY COMPONENT TO THE ANTICIPATED
WARM-UP AND STRONG SUB-TROPICAL RIDGE FOR THE EASTERN THIRD OF THE
COUNTRY OVER THE SECOND HALF OF THE WEEKEND THROUGH MEMORIAL DAY.

TEMPERATURES FRIDAY WILL WARM INTO THE 60S FOR MANY PORTIONS OF THE
NORTHERN IL/NORTHWEST IN...THE EXCEPTION WILL BE LOCATIONS ADJACENT
TO LAKE MICHIGAN WHERE TEMPS MAY STRUGGLE TO REACH 60 DEGREES.

FLOW THEN TURNS SOUTHEASTERLY IN ADVANCE OF THE APPROACHING UPPER
LEVEL SYSTEM EXPECTED TO REMAIN OVER THE UPPER MIDWEST LATER THIS
WEEK.

SATURDAY THROUGH WEDNESDAY...
MAIN CHALLENGE FOR THE EXTENDED FORECAST RESIDES WITH TEMPERATURES
AND PLACEMENT OF YET ANOTHER UPPER LEVEL SYSTEM OVER THE UPPER
MIDWEST FOR THE HOLIDAY WEEKEND.

LATE IN THE WEEK THE DOWNSTREAM RIDGE ACROSS THE CANADIAN MARITIME
WILL GRADUALLY STRETCH AND BE ORIENTED FROM THE GULF OF MEXICO
NORTHEAST THROUGH NEW ENGLAND. WITH AN ANOMALOUSLY STRONG TROUGH
OVER THE EASTERN CARIBBEAN...THIS WILL ALLOW FURTHER RIDGING TO TAKE
PLACE ACROSS THE GULF AND EVENTUALLY OVERSPREAD THE OHIO VALLEY AND
PORTIONS OF THE GREAT LAKES AS A SUBTROPICAL RIDGE DEVELOPS.

THIS RIDGE IS EXPECTED TO PROVIDE CONSIDERABLE WARMTH TO OUR CWFA
SUN/MON (MEMORIAL DAY)...AS A POTENT 850MB THERMAL RIDGE OF 23 TO 25
DEG C PUSHES OVERHEAD. GUIDANCE CONTINUES TO SUGGEST TEMPS BOTH
SUN/MON WILL WARM WELL INTO THE 80S. WITH THE RIDGE AXIS LOCATED
SOUTHEAST OF OUR REGION...A STEADY SOUTHWEST FLOW OF WARM AIR IS
EXPECTED TO ADVECT OVER ILLINOIS. GIVEN THIS ANTICIPATED
SCENARIO...AFTN TEMPS WILL UNDERGO FURTHER MODIFICATION CLOSER TO
DOWNTOWN CHICAGO.

THE LARGER CHALLENGE WILL BE THE PROXIMITY OF A RING-OF-FIRE SETTING
UP ACROSS THE CENTRAL PLAINS AND SLIDING ALONG THE NORTHERN
PERIPHERY OF THE RIDGE. THIS PATTERN IS CONDUCIVE OF PRODUCING A
SERIES OF MCS...WITH ABUNDANT LLVL MOISTURE BEING ADVECTED INTO THE
CENTRAL PLAINS.

THIS SYSTEM TAKES ON A SIMILAR CHARACTERISTICS TO THE SERIES OF
COMPLEXES OF THUNDERSTORMS THAT WERE NOTED IN JULY OF 2010...WHICH PRODUCED
FLOODING OVER PORTIONS OF IOWA/WISCONSIN/ILLINOIS. PRIOR TO THIS
MUCH OF THE U.S. EAST OF THE MISSISSIPPI RIVER WAS IN THE MIDST OF
WIDESPREAD HEAT AND HUMIDITY. WHILE THERE ARE DIFFERENCES...THE
OVERALL PATTERN SUGGESTED BY THE ANOMALIES OF PWAT/MFLUX THAT AN
ACTIVE MON/TUE MAY BE EXPECTED FOR PORTIONS OF THE MIDWEST
POSSIBLY GREAT LAKES REGIONS. THE CHALLENGE IS THE PRECISE
PLACEMENT OF THIS. IT SHOULD BE NOTED THAT GEFS MEMBERS WITHIN THE
LATEST CYCLE ARE WEAKENING THE RIDGE EARLIER AND PLACEMENT IS
FURTHER SOUTH.

//DISCUSSION...UPDATED 06Z...

AS THE UPPER LOW HAS BEEN GRADUALLY MOVING EAST ACROSS CENTRAL MO
WED EVENING ALL THE THUNDERSTORMS HAVE MOVED WELL TO THE EAST OF
THE LOCAL AREA. HOWEVER...RAINS HAS BEEN SLOWLY EXPANDING IN
COVERAGE FROM NORTHEASTERN O AND FAR SOUTHWESTERN IA ACROSS NORTH
CENTRAL AND NORTHEAST IL IN THE DEFORMATION ZONE TO THE NORTH AND
NORTHEAST OF THE UPPER LOW CENTER. CONTINUED EASTWARD TRACK OF THE
UPPER LOW TO EAST CENTRAL IL BY MIDDAY THU AND TO WEST CENTRAL IN
BY EARLY EVENING WILL RESULT IN THE DEFORMATION ZONE ALSO SHIFTING
FURTHER EAST PULLING THE BACK EDGE OF THE RAIN AREA EAST AND
SOUTHEAST OF THE CHI TERMINALS THUS HAVE RAIN ENDING AT 18Z.

CURRENTLY A RATHER LARGE AREA OF IFR CEILINGS IS CENTERED OVER THE
NORTHEAST IL WHERE PERSISTENT RAINFALL COUNTERS THE INFLUX OF
DRIER LOW LEVEL AIR OF MODERATELY STRONG NORTHEAST TO NORTH-
NORTHEAST LOW LEVEL FLOW. THIS IS KEEPING THE LOW LEVELS SATURATED
WHILE THE MIXING AT THE SURFACE DUE TO THE WINDS APPEARS TO BE
KEEPING THE STRATUS OFF THE DECK AS NO SIGNIFICANT RESTRICTIONS
DUE TO FOG NOTED ANYWHERE IN THE AREA.

AS STATED ABOVE THE GRADUAL EASTWARD PROGRESSION OF THE MID MS
VALLEY STORM SYSTEM WILL BRING AN END TO THE RAIN LOCALLY
MIDDAY...AND ALSO ALLOW DRIER AIR CURRENTLY OVER THE NORTHERN
GREAT LAKES SOUTH TO SOUTHERN LOWER MI FAR NORTHERN IL AND EASTERN
IA TO DRY THE LOW LEVELS. EXPECT CLOUDS TO LIFT MVFR AS A RESULT
BY LATER MORNING AND EVENTUALLY TO VFR BY MID TO LATE AFTERNOON.

250 AM CDT

LOW PRESSURE IS MOVING ACROSS EASTERN MISSOURI INTO ILLINOIS THIS
MORNING AND WILL CONTINUE TO SLOWLY TRACK EAST ACROSS INDIANA TODAY.
OVER LAKE MICHIGAN...MODERATE NORTHEAST TO NORTH FLOW IS EXPECTED TO
CONTINUE THROUGH TODAY AND OVERNIGHT AS A TIGHT PRESSURE GRADIENT
PERSISTS BETWEEN THE LOW AND HIGH PRESSURE OVER MANITOBA. THIS RIDGE
WILL BEGIN TO MOVE OVER THE LAKE ON FRIDAY ALLOWING WINDS AND
EVENTUALLY WAVES TO DIMINISH. UNTIL THEN...A SMALL CRAFT ADVISORY
WILL BE IN PLACE OVER THE INDIANA AND ILLINOIS NEARSHORE WATERS
WITH WINDS UP TO 30 KTS EXPECTED. ANOTHER WEAK LOW PRESSURE SYSTEM
WILL MOVE ACROSS THE REGION THIS WEEKEND...BUT WINDS ARE NOT
EXPECTED TO BE AS STRONG WITH A WEAKER GRADIENT IN PLACE. THE NEXT
PERIOD OF CONCERN FOR STRONGER WINDS WILL BE NEXT TUESDAY AS LOW
PRESSURE IS EXPECTED TO MOVE NORTH ACROSS THE WESTERN GREAT LAKES
AND SOUTHERLY FLOW RAMPS UP AHEAD OF A COLD FRONT.
