AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL
305 PM CST SUN NOV 4 2007

.DISCUSSION...
305 PM CST

CHANGES ARE ON THE WAY FOR TOMORROW WITH MUCH COLDER TEMPERATURES
AND WINDY CONDITIONS.

STRONG PRESSURE FALLS ARE ALREADY UNDERWAY ACROSS THE NORTHERN
PLAINS IN ADVANCE OF A 110 KNOT UPPER JET STREAK MOVING THROUGH
EASTERN MONTANA AND THE WESTERN DAKOTAS. MAIN UPPER LEVEL CYCLONIC
CIRCULATION IS STILL LOCATED ACROSS NORTHERN SASKATCHEWAN AND
NORTHWEST MANITOBA. A STRONGER UPPER JET ACROSS SOUTHWEST CANADA
WILL DIVE INTO NORTHERN PLAINS TONIGHT...AND THEN INTO THE SOUTHERN
GREAT LAKES ON MONDAY. THIS WILL ALLOW THE UPPER LOW ACROSS SOUTHERN
CANADA TO TRACK SOUTHEAST INTO THE NORTHERN GREAT LAKES TOMORROW
AFTERNOON WITH COLD FRONT PASSAGE ACROSS THE FORECAST AREA MONDAY
MORNING INTO EARLY AFTERNOON. MOISTURE IS RATHER LIMITED IN ADVANCE
OF THE LOW LEVEL FRONT ALTHOUGH THERE MAY BE ENOUGH LOW AND MID
LEVEL MOISTENING TO ALLOW FOR FEW SHOWERS TO DEVELOP OVERNIGHT.
COVERAGE SHOULD BE LIMITED WITH ANY SHOWERS THAT DO DEVELOP AND WILL
ONLY MENTION ISOLATED POPS IN THE FORECAST FOR OVERNIGHT. OVERNIGHT
MINS MAY OCCUR LATER THIS EVENING GIVEN INCREASING MID CLOUD AND
INCREASING SOUTHWEST WINDS IN ADVANCE OF THE FRONT...ALTHOUGH MAY
END UP BEING MORE OF A STEADY TEMPERATURE TREND IN THE LOWER TO MID
40S OVERNIGHT.

COLD FRONT STILL APPEARS TO BE ON TRACK FOR MONDAY MORNING AND MAIN
CONCERN WILL BE ON POTENTIAL FOR STRONG WINDS BEHIND THE FRONT.
FORECAST SOUNDINGS INDICATE MIXING UP TO 850 HPA TOMORROW AFTERNOON
BEHIND THE COLD FRONT WITH 40 KNOT 850 HPA WINDS. POTENTIAL FOR
GREATEST GUSTS ARE EXPECTED DURING THE AFTERNOON WHEN MIXED LAYER IS
THE DEEPEST...BUT MAY NUDGE UP AGAINST WIND ADVISORY CRITERIA DURING
THE MORNING HOURS IN ASSOCIATION WITH STRONG PRESSURE RISES
ACCOMPANYING THE FRONTAL PASSAGE. WIND SPEEDS ARE EXPECTED IN THE 25
TO 35 MPH RANGE WITH GUSTS UP TO AROUND 45 MPH DURING THE AFTERNOON.
WILL BE ISSUING A WIND ADVISORY FOR THE ENTIRE FORECAST AREA ON
MONDAY RUNNING FROM 14Z TO 02Z. NON DIURNAL TEMPERATURE TREND
TOMORROW STILL APPEARS TO BE REASONABLE WITH FALLING TEMPERATURES
TOMORROW AFTERNOON THROUGH THE 40S ALTHOUGH STRONG WINDS WILL MAKE
IT FEEL COLDER. OUTSIDE OF A CHANCE OF PRE FRONTAL RAIN SHOWERS
ACROSS FAR NORTHWEST INDIANA EARLY MONDAY MORNING...ONLY PRECIP ON
MONDAY SHOULD BE IN THE FORM OF A FEW SPRINKLES ASSOCIATED WITH THE
STRONG COLD ADVECTION MONDAY MORNING.

ON TUESDAY...SECONDARY SFC TROUGH IS EXPECTED TO ROTATE SOUTHWARD
INTO NORTHERN ILLINOIS DURING THE MORNING WHICH SHOULD ALLOW FOR
CONTINUED WINDY CONDITIONS ON TUESDAY...BUT NOT LIKELY TO ADVISORY
LEVELS. DID ALSO MAINTAIN MENTION OF POSSIBLE FLURRIES DURING THE
MORNING WITH THIS SECONDARY TROUGH. SKIES SHOULD CLEAR OFF TUESDAY
EVENING AS UPPER HEIGHTS BUILD ACROSS THE UPPER MIDWEST AND UPPER
LOW TRACKS ACROSS SOUTHERN QUEBEC. ANOTHER SMALLER SCALE UPPER LEVEL
SHORT WAVE TROUGH WILL TRACK ACROSS SOUTHERN ONTARIO WEDNESDAY NIGHT
SETTING UP ANOTHER WEAK SFC TROUGH PASSAGE ACROSS THE WESTERN GREAT
LAKES ON THURSDAY. PRECIP WITH THIS SYSTEM SHOULD BE CONFINED TO THE
NORTHERN GREAT LAKES HOWEVER. TEMPS ON WED/THU WILL MODERATE
SLIGHTLY BACK INTO THE MID 40S...WITH COLDEST TEMPS LIKELY TUESDAY
NIGHT AS SURFACE HIGH BUILDS WITH CLEARING SKIES.

FURTHER MODERATION IN TEMPERATURES STILL APPEARS LIKELY FOR THE END
OF THE WEEK AS UPPER FLOW BECOMES LESS AMPLIFIED. CONFIDENCE
DWINDLES TOWARD NEXT WEEKEND WITH LATEST GFS INDICATING ANOTHER
AMPLIFIED UPPER TROUGH MOVING INTO THE UPPER MIDWEST/GREAT LAKES.
THERE IS SOME AGREEMENT BETWEEN LATEST GFS AND ECMWF ALTHOUGH RUN TO
RUN CONSISTENCY HAS BEEN SOMEWHAT POOR OF LATE DURING THIS PERIOD SO
HAVE MADE FEW CHANGES TO SATURDAY/SUNDAY AT THIS TIME AND WILL KEEP
DRY FOR NOW.
