AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
341 PM CDT MON SEP 6 2010
.DISCUSSION...
328 PM CDT
WINDY CONDITIONS WILL OCCUR TUESDAY.
TONIGHT...WE WILL FORECAST A SLIGHT CHANCE OF THUNDERSTORMS BETWEEN
MIDNIGHT AND EARLY TUESDAY MORNING. A STRONG FRONT WILL MOVE
THROUGH NORTHERN ILLINOIS AND NORTHWEST INDIANA. THE AIR IS
DRY...AS SEEN ON THE SOUNDINGS THIS MORNING AT ILX AND DVN. THE
FORECAST SOUNDINGS FROM THE NAM AND LOCAL WRF MODEL SHOW MOSTLY
DRY SOUNDINGS OVERNIGHT. THE FRONT WILL HAVE ENOUGH DYNAMICS AND
SURFACE CONVERGENCE THAT AN ISOLATED THUNDERSTORM MAY OCCUR. WE
USED THE FORECAST TEMPERATURES FROM A CONSOLIDATION OF MOS OUTPUT
FROM THE VARIOUS MODELS. THE MEAN ABSOLUTE ERRORS WERE THE LOWEST.
WE USED THE LOCAL WRF MODEL AND NAM FOR THE MOVEMENT OF THE FRONT
BECAUSE OF THOSE MODELS FORECAST OF UPPER AIR WIND SPEEDS.
TUESDAY...WE WILL ISSUE A WIND ADVISORY FOR THE NORTHERN TWO THIRDS
OF OUR COUNTIES IN NORTH CENTRAL ILLINOIS...NORTHEAST ILLINOIS
AND NORTHWEST INDIANA. A STRONG WIND OF 30 MPH WITH GUSTS TO 45
MPH IS EXPECTED TUESDAY AFTERNOON. THERE WILL BE A LOT OF MIXING
FROM 800 MB TO THE SURFACE. THE WIND BETWEEN 700 MB AND 800 MB IS
FORECAST TO BE AS HIGH AS 55 KNOTS. A LOT OF MOMENTUM CAN BE MIXED
DOWN TO THE SURFACE. THE SURFACE LOW IS FORECAST TO MOVE FROM
SOUTHWEST MINNESOTA TO SOUTHERN QUEBEC BY TUESDAY. THE PRESSURE
WILL FALL AND THE PRESSURE GRADIENT IS EXPECTED TO INCREASE FROM
ONTARIO TO ILLINOIS. WE USED THE ECMWF MODEL AND LOCAL WRF MODEL
FOR THE FORECAST. WE EXPECT DRY WEATHER AND SOME LOWER
TEMPERATURES FOR TUESDAY.
WEDNESDAY THROUGH THURSDAY....THERE WILL BE DRY WEATHER WEDNESDAY.
WE WILL FORECAST A CHANCE OF SHOWERS AND THUNDERSTORMS FOR
THURSDAY AND THURSDAY NIGHT. A 500 MB SHORT WAVE TROUGH WILL MOVE
INTO CENTRAL ILLINOIS AS WARM AIR RETURNS TO NORTHERN ILLINOIS AND
NORTHWEST INDIANA.
FRIDAY THROUGH SUNDAY...ANOTHER 500 MB TROUGH WILL MOVE MOVE ACROSS
THE GREAT PLAINS FRIDAY NIGHT AND SATURDAY. THE 500 MB TROUGH
IS FORECAST TO BE OVER WISCONSIN BY MIDNIGHT SUNDAY MORNING. WE
WILL FORECAST COOLER WEATHER AND A CHANCE OF THUNDERSTORMS
SATURDAY AND SATURDAY NIGHT.
&&
.FIRE WEATHER...
330 AM CDT
THE WIND HAS INCREASED TODAY. CLOUDS AND SOME LIGHT SHOWERS MAY
HAVE KEPT THE HUMIDITY ABOVE 25 PERCENT. HOWEVER...WE WILL MONITOR
FIRE WEATHER CONDITIONS TODAY AND TUESDAY. THE WIND SPEED WILL BE
HIGHER TUESDAY AND WITH FEWER CLOUDS THERE MAY BE MORE
EVAPORATION AND LOWER RELATIVE HUMIDITY. THAT WILL INCREASE THE
FIRE WEATHER DANGER SIGNIFICANTLY.
&&
.AVIATION...
//ORD AND MDW CONCERNS...UPDATED 20Z...
PRIMARY CONCERN WILL BE WINDS. EXPECT MAX GUSTS CLOSE TO 25-30KT
THIS AFTERNOON. STRONGER WINDS LIKELY TOMORROW.
SMALL CHANCE OF ISOLD LIGHT SHRA/SPRINKLES. WETTING RAIN VERY
UNLIKELY.
KREIN
//DISCUSSION...UPDATED 18Z...
THE MAIN ISSUE FOR THE NEXT 24-36 HOURS WILL BE WINDS. WITH
DEEPENING LOW PRESSURE TRACKING NEWD THROUGH THE UPPER MISSOURI
VALLEY AND HIGH PRESSURE PARKED OVER THE EAST COAST...A TIGHTENING
PRESSURE GRADIENT IS TRANSLATING TO STRONG SOUTHERLY WINDS OVER
THE UPPER MIDWEST. LATEST OBS SHOW WINDS ALREADY GUSTING INTO THE
LOW 20S KTS AND EXPECTED CLEARING SKIES WILL ALLOW FURTHER DEEP
LAYER MIXING SO EXPECT GUSTS TO PEAK CLOSE TO 30KT DURG THE LATE
AFTERNOON HOURS. WINDS SHOULD DECREASE SOME WITH SUNSET...BUT THE
STRONG GRADIENT WILL KEEP CONDITIONS QUITE BREEZY OVERNIGHT. AS
THE LOW TRACKS THROUGH THE UPPER GREAT LAKES TOMORROW...IT WILL
DRAG A COLD FRONT ACROSS THE AREA...TURNING WINDS MORE WLY BY LATE
MORNING TOMORROW. EXPECT WINDS TO BE EVEN STRONGER TOMORROW...AND
WITH SKIES EXPECTED TO BE MOSTLY CLEAR...AMPLE SUNSHINE WILL ALLOW
MIXING DOWN OF WINDS CLOSE TO 40KT.
FOR PCPN...THE THUNDER POTENTIAL HAS ENDED WITH THE INITIAL PATCH
OF PCPN MOVING OFF TO THE EAST. ANOTHER AREA OF SHOWERS IS MOVING
THROUGH NRN IL...BUT AS THE PCPN MOVES EWD...IT IS MOVING INTO
MORE STABLE AIR...AND WHILE A FEW ISOLD SPRINKLES ARE NOT OUT OF
THE QUESTION...PARTICULARLY AT RFD/DPA...DO NOT EXPECT ANY WETTING
RAIN TO OCCUR AT THE TERMINALS.
KREIN
//ORD AND MDW CONFIDENCE...UPDATED 20Z...
HIGH CONFIDENCE IN ALL FORECAST ELEMENTS.
KREIN
//OUTLOOK FOR ORD/MDW FOR 06Z WEDNESDAY-12Z MONDAY...UPDATED 18Z...

TUESDAY MORNING AND LASTING THROUGH TUESDAY EVENING.
LOW PRESSURE OVER WESTERN IA WILL LIFT NORTH TO LAKE SUPERIOR BY
TUESDAY AFTERNOON. IN ADDITION TO THE TIGHT PRESSURE GRADIENT WITH
THIS SYSTEM...MUCH COLDER AIR ALOFT WILL SPREAD ACROSS THE GREAT
LAKES. AS IT DOES...THE LOW LEVELS WILL BECOME VERY WELL MIXED AND
STRONG WINDS ALOFT WILL MIX TO THE SURFACE. CURRENT FORECAST/GRIDS
HAVE OVERALL TIMING OF GALES HANDLED WELL BUT GIVEN THE STRENGTH OF
THE WINDS ALOFT...HAVE BUMPED SPEEDS UP TO 45 KTS. THE LOW WILL
CONTINUE INTO QUEBEC WEDNESDAY AS IT WEAKENS. THE GRADIENT WILL
BEGIN TO RELAX FROM SOUTH TO NORTH ACROSS LAKE MICHIGAN TUESDAY
NIGHT AS A RIDGE OF HIGH PRESSURE SLOWLY BUILDS EAST ACROSS THE
WESTERN LAKES. CMS
