Winter Storm and Winter Weather in Illinois, February 1, 2008

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE PADUCAH KY
846 PM CST THU JAN 31 2008

.UPDATE...
UPDATED FOR LATEST TRENDS WITH THE WINTER STORM TONIGHT AND FRIDAY.

&&

.DISCUSSION...
MAIN PROBLEM FOR THE FORECAST TONIGHT IS THE TRACK OF THE SURFACE
LOW AND ITS IMPACT ON NEAR SURFACE TEMPERATURES. AS OF 02Z THE
SURFACE LOW WAS NEAR DYERSBURG TENNESSEE...AND THE FREEZING LINE
RAN FROM POPLAR BLUFF MISSOURI TO MARION AND MT CARMEL ILLINOIS.
MOST LOCATIONS WERE REPORTING RAIN OR FREEZING RAIN...BUT NOT MUCH
IMPACT AS FAR AS ICING HAS BEEN REPORTED SO FAR THIS EVENING...EXCEPT
FOR THE NORTHERN PORTIONS OF SOUTHERN ILLINOIS AND THE HIGHER
TERRAIN OF SOUTHEAST MISSOURI.

THE 00Z NAM LOOKS REALLY GOOD IN ITS INITIAL SURFACE LOW POSITION
JUST NORTH OF MEMPHIS AT 00Z. IT LIFTS IT NORTHWARD TO NEAR
PADUCAH BY 06Z...AND THEN NORTHEAST UP THE WABASH RIVER VALLEY AND
WELL INTO SOUTHERN INDIANA BY 12Z FRIDAY. THIS IS BY FAR THE MOST
WESTERLY SURFACE LOW PATH SEEN IN THE MODELS TODAY...AND
CERTAINLY IS BOLSTERED BY THE CURRENT OBSERVATIONS. EVEN THE 21Z
SREF ENSEMBLE MEAN IS HINTING AT THIS POSSIBILITY. THIS IS FURTHER
WEST THAN CURRENTLY FORECAST IN THE GRIDS...AND CONTINUES THE
OVERALL TREND TOWARD A WARMER SOLUTION WITH THIS SYSTEM.

THE 00Z NAM SOUNDING DATA INDICATES THAT THE PRECIPITATION SHOULD
BEGIN TO CHANGE OVER TO ALL SNOW LATER THIS EVENING FROM WEST TO
EAST...AS THE UPPER LOW...CURRENTLY LOCATED OVER SOUTHWEST
MISSOURI/NORTHWEST ARKANSAS...PIVOTS EAST AND TAKES ON MORE OF A
NEGATIVE TILT TOWARD SOUTHEAST MISSOURI BETWEEN 03Z AND 06Z. THIS
CHANGE OVER SHOULD CONTINUE EASTWARD INTO THE EARLY MORNING HOURS
IN THE SOUTHERN ILLINOIS PORTION OF THE HEAVY SNOW WARNING. MODEL
QPF SUPPORTS 2-4 INCHES OF ADDITIONAL SNOWFALL...SO THE WARNING
SHOULD BE FINE...AND LITTLE CHANGE IS ANTICIPATED WITH THE EVENING
UPDATE.

THE PROBLEMS ARE OVER THE REMAINDER OF THE REGION...WHERE THE WARM
NEAR SURFACE AIR WILL KEEP THE PRECIPITATION AS A COLD RAIN FOR
MUCH OF THE NIGHT. OF COURSE...AS THE SURFACE LOW LIFTS NORTHEAST
AFTER 06Z...SUB-FREEZING TEMPERATURES WILL FINALLY WRAP EASTWARD
THROUGH THE AREA...EVENTUALLY ALLOWING SNOW TO FALL OVER THE
ENTIRE AREA TOWARD 12Z. WITH THE POSSIBILITY OF SUB-FREEZING AIR
ARRIVING AT THE SURFACE IN THE WINTER STORM WARNING AREA...SOME
FREEZING RAIN...AND A BRIEF PERIOD OF SLEET MAY OCCUR BEFORE THE
SNOW ARRIVES. DUE TO THE LATER CHANGE OVER...AND DIMISHING MODEL
QPF...FINAL SNOW AMOUNTS MAY ONLY TOTAL 1-2 INCHES IN THIS AREA.
HOWEVER...WITH THE POTENTIAL FOR SOME FREEZING RAIN OR SLEET
BEFORE THE FINAL CHANGE OVER TO SNOW...THE WINTER STORM HEADLINE
LOOKS FINE AND WILL NOT CHANGE THIS EVENING.

FINALLY OVER THE FAR SOUTH AND EAST...THE ADVISORY AREA SIMILARLY
LOOKS GOOD. THE CHANGE OVER TO SNOW WILL LIKELY OCCUR JUST BEFORE
12Z IN THIS AREA...WITH LITTLE ACCUMULATION EXPECTED BEFORE DAY
BREAK. HOWEVER...THE POTENTIAL FOR SOME MINOR ICING AND AN INCH OR
LESS OF SNOWFALL CERTAINLY WARRANT THE ADVISORY.

WILL MAKE SOME TWEAKS AND UPDATE PRODUCTS BY 04Z.

&&

.AVIATION...
MULTIPLE PCPN TYPES...INCLUDING FREEZING RAIN...WILL BE
POSSIBLE AT THE TAF SITES THROUGH THE EVENING...FOLLOWED BY A
GRADUAL TRANSITION TO SNOW OVERNIGHT FROM WEST TO EAST. LOW END MVFR
TO IFR CONDITIONS WILL DEVELOP/CONTINUE WITH RESPECT TO CLOUDS AND
OCCASIONALLY VSBYS. THE ERLY COMPONENT WITH SURFACE WINDS WILL
BECOME WEST/NORTHWEST OVERNIGHT AND GUSTY AT TIMES AS A LOW PRESSURE
AREA MOVES NE ACROSS THE REGION. CONDITIONS WILL IMPROVE
DRAMATICALLY AFTER 18Z ESPECIALLY IN SERN MO.

&&

.PREV DISCUSSION... /ISSUED 157 PM CST THU JAN 31 2008/

DISCUSSION...
WIDESPREAD PRECIPITATION OF MULTIPLE FORMS WITH LARGE SHIELD
MOVING ACROSS THE AREA EARLY THIS AFTERNOON. MOSTLY SNOW FROM
SE MISSOURI INTO SW ILLINOIS WITH SOME SLEET MIXED IN. FREEZING
RAIN...RAIN AND SLEET...WITH A MIX OF SNOW NOTED EAST OVER THE
REST OF THE AREA.

MAIN CONCERN EARLY ON...IS PRECIP COVERAGE. NOTABLE DRY SLOT
WAS ACROSS ARKANSAS. HOWEVER...THE PARENT UPPER LOW WAS SEEN
ON WVAPOR MOVG EAST ACROSS OKLAHOMA...AND SHOULD REACH WEST
ARKANSAS BY 00Z. SNOW WAS PREVALENT ALONG AND NORTH OF THE
TRACK. ALSO...NEW RETURNS SHOWING UP ACROSS THE KLZK CWFA.
THEREFORE AM LEADING TOWARD THE NAM MODEL IN SHOWING ADDITIONAL
FORMATION WILL BE POSSIBLE DESPITE THE PRESENCE OF THE DRY
SLOT...AS THE UPPER LOW HEADS EAST...REACHING SOUTHERN IL BY 12Z
FRIDAY. THEREFORE WILL KEEP OUR WARNINGS AND ADVISORIES AS THEY
ARE. LOOKING AT 4-6 INCHES WITH ISOLD 8 IN THE HEAVY SNOW WARNING
AREA...1-4 IN THE WINTER STORM WARNING AREA WITH SOME ICE AND
SLEET ALSO POSSIBLE BEFORE TRANSITIONING TO SNOW. MAINLY LIQUID IN
THE ADVISORY AREA TO START WITH A BRIEF MIX...FOLLOWED BY A
TRANSITION TO A WINTRY MIX OVERNIGHT AS WELL. THE SNOW SHOULD
GRADUALLY TAPER OFF FROM SW TO NE ON FRIDAY. WILL KEEP THE
EXPIRATION TIMES AS THEY ARE (NOON CST) TO AVOID FLIP FLOP. THINK
PART OF THE AREA WILL BE THROUGH WITH THE STORM WELL BEFORE THEN
THOUGH. THEY CAN BE CANCELED ACCORDINGLY. TEMPS AND DEW POINTS
WERE A BLEND OF THE NAM12 AND RUC13 2M TEMPS EARLY ON AND A BLEND
OF MAV/MET FOR LOWS.

VERY ACTIVE PATTERN WILL CONTINUE INTO THE LONG TERM. ANOTHER POTENT
500 MB SHORTWAVE WILL EJECT NORTHEAST FROM THE SOUTHERN PLAINS EARLY
IN THE WEEK. THE ASSOCIATED SURFACE LOW WILL TRACK NORTHEAST ACROSS
THE MID/UPPER MISSISSIPPI VALLEY INTO THE GREAT LAKES REGION. THE
TRAILING COLD FRONT WILL CROSS THE FORECAST AREA TUESDAY BASED ON
00Z ECMWF AND HPC GUIDANCE. 00Z GFS GUIDANCE APPEARS TOO SLOW.

A STRONG SOUTHERLY LOW LEVEL JET WILL DEVELOP AHEAD OF THE FRONT
MONDAY...WITH ACCOMPANYING SURGE OF LOW LEVEL MOISTURE. AS WITH MOST
WINTER CONVECTIVE POTENTIAL...ONLY MARGINAL INSTABILITY WOULD BE
NECESSARY FOR SIGNIFICANT CONVECTIVE POTENTIAL GIVEN EXTREME SHEAR
VALUES. MOS GUIDANCE UNDERESTIMATED SURFACE WARMTH AND MOISTURE
RETURN WITH THE LAST EVENT /TUESDAY/. FORECAST TEMPS AND DEW POINTS
WILL BE SHADED ABOVE MOS GUIDANCE IN THE WARM SECTOR MONDAY AND
TUESDAY. THUNDER CHANCES WILL BE FORECAST MONDAY INTO TUESDAY.

OUTSIDE OF THE MONDAY/TUESDAY SYSTEM...FORECAST IS GENERALLY DRY.
TEMPS FRIDAY NIGHT THROUGH SATURDAY NIGHT WILL BE STRONGLY AFFECTED
BY ANY SNOW COVER LEFT BY THE CURRENT SYSTEM. AN UNUSUALLY STRONG
TEMP GRADIENT WILL BE FORECAST FRIDAY NIGHT THROUGH SATURDAY NIGHT
BASED ON THE IDEA SNOW COVER WILL COOL NORTHERN AND WESTERN
COUNTIES. PRECIP CHANCES WILL GRADUALLY INCREASE LATE SUNDAY INTO
SUNDAY NIGHT AS LOW LEVEL WARM ADVECTION DEVELOPS UNDER MOIST
WEST/SOUTHWEST UPPER FLOW.

FINAL TWO DAYS OF THE LONG TERM /WEDNESDAY AND THURSDAY/ ARE
EXPECTED TO BE DRY AND SEASONABLY COLD IN THE WAKE OF THE DEPARTING
STORM SYSTEM.

AVIATION...
MULTIPLE PRECIPITATION TYPES WILL BE POSSIBLE AT THE TAF SITES
THROUGH EARLY EVENING...FOLLOWED BY A GRADUAL TRANSITION TO SNOW
OVERNIGHT. LOW END MVFR TO IFR CONDITIONS WILL CONTINUE WITH
RESPECT TO CLOUDS AND OCCASIONALLY VSBYS. THE EASTERLY COMPONENT
WITH SURFACE WINDS WILL BECOME WEST/NORTHWEST OVERNIGHT AND GUSTY
AT TIMES.
