AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
711 AM CDT SUN MAR 8 2009

.DISCUSSION...
507 AM CDT

HAVE MADE A LAST SECOND UPDATE TO THE FORECAST TO BOOST UP
TEMPERATURES AND DEW POINTS IN THE WARM SECTOR TODAY. WITH
TEMPERATURES CURRENTLY IN THE LOW TO MID 60S...SEE NO REASON THAT
DURING THE PEAK HEATING OF THE AFTERNOON THAT THE WARM SECTOR
WONT GET INTO THE MID TO UPPER 60S AND POSSIBLY TOP 70. ALL THIS
MEANS A GREATER RISK FOR SEVERE WEATHER IN THAT SECTOR WITH 6Z NAM
SOUNDINGS INDICATING SBCAPE VALUES OF OVER 1000 J/KG. HAVE ALSO
TAKEN THE FRONT A BIT FURTHER NORTH TO APPROXIMATELY THE SOUTHERN
RIM OF LAKE MICHIGAN WESTWARD.  UPDATE TO THE ZONES FORTHCOMING.

HALBACH

PREV DISCUSSION...
313 AM CDT

NOT MANY CHANGES MADE TO THE GOING FORECAST WITH JUST SOME MINOR
ADJUSTMENTS HERE AND THERE WITH FLOODING AND SEVERE THREAT
REMAINING A CONCERN FOR TODAY.

SWATH OF MODERATE RAIN WITH SOME EMBEDDED THUNDERSTORMS CONTINUES
TO TRAIN ALONG THE 850MB BAROCLINIC ZONE ANGLING FROM NORTHEAST
KANSAS UP ALONG THE SOUTHERN GREAT LAKES. ANY POTENTIAL FOR
MARGINALLY SEVERE STORMS APPEARS LOW THROUGH THIS MORNING WITH THE
MAIN FOCUS FOR THIS DEVELOPMENT ALONG THE SOUTHERN PERIPHERY OF
THE SWATH. UPPER LEVEL VORT MAX EVIDENT ON WATER VAPOR IMAGERY AND
PROFILER DATA OVER NEBRASKA WILL PROPAGATE EAST AND IS FORECAST TO
REACH LAKE MICHIGAN AROUND 00Z MONDAY. AT THE SFC...AN AREA OF LOW
PRESSURE WILL LIFT FROM SOUTHEAST KANSAS INTO NORTH CENTRAL
ILLINOIS AROUND MID-AFTERNOON. THIS WILL ALSO LIFT THE FRONT
NORTHWARD AND BRING THE WARM SECTOR INTO THE SOUTHEAST PORTION OF
THE CWA BRIEFLY LETTING TEMPERATURES TAP THE UPPER 50S TO LOW 60S.
FORECAST SOUNDINGS OUT OF THE WARM SECTOR INDICATE QUITE A BIT OF
SPEED SHEAR AND SOME DIRECTIONAL SHEAR ALTHOUGH INSTABILITY IS
RATHER MARGINAL WITH MUCAPE EXPECTED TO TOP OUT AROUND 500-750
J/KG. REGARDLESS...THIS AMOUNT OF WIND SHEAR SHOULD BE ABLE TO
OVERCOME ANY LACKING INSTABILITY. CURRENT THINKING IS THAT STORMS
WILL DEVELOP OUT AHEAD OF THE COLD FRONT IN THE WARM SECTOR THAT
HAVE THE POTENTIAL TO TAP INTO THE HIGH WIND SHEAR AND BECOME
SUPER CELLULAR. HAVE TRENDED CLOSER TO THE 00Z NAM/ECMWF AS THE
GFS SEEMS TO BE A BIT ON THE FAST SIDE.

FLOODING THREAT WILL CONTINUE THROUGH THIS EVENING AND WITH A MUCH
HIGHER THREAT TODAY AS OPPOSED TO YESTERDAY AS ALMOST ALL OF THE
REGION HAS RECEIVED AN INCH OF RAIN BY SATURDAY EVENING. WITH MORE
INTENSE CONVECTION POSSIBLE TODAY AS THE SFC FRONT LIFTS BACK
NORTH...HAVE THE BETTER CHANCE FOR SEEING SOME RAPID ACCUMULATION
OF RAINFALL.

GET A BRIEF SHOT OF COLD AIR ON THE BACKSIDE OF THE SYSTEM SUNDAY
NIGHT WHICH MAY CHANGE THE PRECIP OVER TO SNOW SHOWERS...BUT IT
CURRENTLY LOOKS LIKE THE PRECIP WILL HAVE ENDED BEFORE THE COLD
AIR GETS IN.

MONDAY IS STILL EXPECTED TO BE A QUIET DAY INTO THE AFTERNOON AS
HIGH PRESSURE PROPAGATES THROUGH THE REGION. TEMPS SHOULD REBOUND
DECENTLY TO AROUND 50 AS WARMER AIR QUICKLY ADVECTS BACK INTO THE
REGION ON THE BACKSIDE OF THE RIDGE...ALTHOUGH WITH SOUTHEASTERLY
WINDS OFF THE LAKE...FAR NORTHEAST ILLINOIS WILL LIKELY STAY COOLER.

NEXT FORECAST CHALLENGE COMES IN WITH THE DYNAMIC SYSTEM ON
TUESDAY. INITIAL SHORTWAVE TROF APPEARS TO COME THROUGH MONDAY
NIGHT INTO TUESDAY TO PROVIDE THE FIRST SHOT AT PRECIPITATION.
KEPT SOME ISOLATED THUNDER IN THE FORECAST ALTHOUGH LAPSE RATES
LOOK SOMEWHAT MEAGER AT THIS POINT. STILL LOOKS LIKE THE
NEGATIVELY TILTING UPPER LOW WILL LEAD TO A RAPIDLY DEEPENING
SFC LOW THAT WILL TRACK THROUGH TO THE NORTH AND WEST OF THE CWA.
STRONG WARM AIR ADVECTION OUT AHEAD OF THE SYSTEM WILL LEAD TO
TEMPERATURES LIKELY GETTING INTO THE 60S. SOME QUESTION REMAINS
ABOUT THE POTENTIAL SEVERE THREAT AS THE LATEST RUNS OF THE MODELS
HAVE BEEN HINTING AT CONVECTION INITIATING WELL TO THE SOUTH WHICH
MAY CHOKE OFF ANY DEVELOPMENT FURTHER NORTH. STILL...WITH THE
STRONG DYNAMICS IN PLACE...LOOKS LIKE A DECENT SHOT AT SOME SEVERE
WEATHER.

AFTER THIS...MAJOR COOL DOWN COMES IN WITH TEMPERATURES STRUGGLING
TO GET ABOVE FREEZING WEDNESDAY AND THURSDAY AS A BROAD RIDGE OF
HIGH PRESSURE MOVES IN ACROSS THE MIDWEST.

HALBACH

.AVIATION...

1200 UTC TAFS...ANOTHER ROUGH DAY FOR AVIATION TODAY WITH LOW CIGS
AND THUNDERSTORMS THIS MORNING...FOLLOWED BY A PERIOD OF STRONG
WINDS THIS AFTERNOON. STILL ANTICIPATE A RETURN TO VFR CONDITIONS
AND LIGHTER WINDS LATER TONIGHT.

FIRST THINGS FIRST...WAVES OF MODERATE RAIN WITH SOME EMBEDDED TS
WILL CONTINUE TO PROPAGATE ACROSS THE TERMINALS THIS MORNING TO
THE NORTH OF THE WARM FRONT. NORTH OF THE WARM FRONT EXPECT
GENERALLY LIFR/VLIFR CIGS TO PERSIST THOUGH STILL PLAUSIBLE THAT
THE LOWER STRATUS COULD BRIEFLY SCATTER OUT FROM TIME TO TIME.
COVERAGE OF RA/ISO TS SHOULD BEGIN TO WANE OVER OUR TERMINALS BY
LATE MORNING/EARLY AFTERNOON AS WARM FRONT LIFTS NORTHWARD. LATEST
SURFACE ANALYSIS HAS SURFACE LOW JUST SE OF MKC WITH STRONGEST
PRESSURE FALLS OVER IA JUSTIFYING THE RECENT SLIGHT NORTHWARD
ADJUSTMENT TO THE TRACK IN THE 06Z MODELS...WHICH GIVEN CURRENT
SFC OBS I WOULDNT BE SURPRISED TO SEE THE LOW TRACK EVEN FARTHER
NORTH THAN WHAT THOSE MODELS ARE SHOWING.

THE MORE NORTHWESTERLY TRACK OF THE SURFACE LOW WILL ALLOW MOST OF
THE TERMINALS TO BREAK INTO THE WARM SECTOR BRIEFLY THIS
AFTERNOON. THAT SHOULD RESULT IN WINDS VEERING TO A MORE SOUTHERLY
DIRECTION AND BECOMING QUITE GUSTY AS BOUNDARY LAYER BECOMES MORE
MIXED. THE ARRIVAL OF THE WARM SECTOR SHOULD ALLOW FOR CIGS TO
LIFT TO AT LEAST MVFR WITH BREAKS IN THE CLOUD COVER AND POSSIBLY
EVEN SCATTERING OUT. IN ADDITION...THE WARM SECTOR WILL ALSO OPEN
UP THE DOOR TO THE POSSIBILITY OF SOME REDEVELOPING THUNDERSTORMS
THIS AFTERNOON ALONG THE COLD FRONT...SOME OF WHICH COULD BE
STRONG/SEVERE.

IN THE WAKE OF THE COLD FRONT/LOW PASSAGE WE SHOULD SEE A PERIOD
OF VERY STRONG WINDS AS VERY STRONG PRESSURE OCCUR IN THE WAKE OF
THE RAPIDLY MOVING LOW PRESSURE. HAVE BUMPED UP GUSTS TO 35KT IN
THE TAFS...BUT EVEN THAT MAY BE A BIT CONSERVATIVE. THE WINDOW OF
TIME FOR THE STRONG WINDS WILL BE SHORT WITH WINDS RAPIDLY
DIMINISHING DURING THE EVENING HOURS.

IZZI

&&

.MARINE...
711 AM CDT

COUPLE ROUGH DAYS AHEAD ON THE LAKE AS A COUPLE OF STORM SYSTEMS
MOVE ACROSS THE AREA. FIRST STORM WILL MOVE RAPIDLY ACROSS THE
SOUTHERN PORTIONS OF THE LAKE TOWARD EVENING. WHILE LOW IS NOT
OVERLY DEEP AND COLD AIR ADVECTION BEHIND THE LOW WILL NOT BE ALL
THAT STRONG...THE LOW WILL BE MOVING VERY RAPIDLY AND BEGIN TO
FILL AFTER CROSS THE LAKE. THIS WILL RESULT IN A VERY STRONG
ISALLOBARIC RESPONSE TO THE WINDS WITH GUSTS WELL INTO GALE FORCE
RANGE FOR A FEW HOURS THIS EVENING. WINDS WILL VERY RAPIDLY
SUBSIDE IN THE WAKE OF THE LOW OVERNIGHT WITH WINDS LIKELY
DROPPING BELOW GALE FORCE BY 06Z OR SHORTLY AFTER.

NEXT CONCERN WILL BE WITH THE INTENSE STORM TRACKING WEST OF THE
LAKE TUESDAY NIGHT INTO WEDNESDAY. EXPLOSIVE DEEPENING AT THE RATE
OF 1MB PER HOUR IS FORECAST FOR AN 18-24 HOURS PERIOD FROM TUESDAY
AFTERNOON INTO WEDNESDAY. THE RAPID DEEPENING...VERY QUICK
MOVEMENT OF THE LOW...INTENSE COLD AIR ADVECTION IN ITS WAKE...AND
STRONG HIGH MOVING IN ALL POINT TO THE POSSIBILITY FOR STORM FORCE
WINDS OVER THE LAKE. FOR NOW HAVE BUMPED UP WINDS TO STORM FORCE
OVER NORTHERN PORTIONS OF THE LAKE WHERE CHANCES APPEAR TO BE THE
GREATEST...THOUGH CHANCE REALLY DOES EXIST EVEN OVER SOUTHERN
PORTIONS OF THE LAKE. STILL TOO EARLY FOR A STORM WATCH BUT HAVE
HIGHLIGHTED THE THREAT IN THE HWO.
