AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
545 AM CDT SUN MAR 29 2009

.DISCUSSION...
/412 AM CDT SUN MAR 29 2009/
THE SECOND DEFORMATION ZONE DEVELOPED PRETTY MUCH ON SCHEDULE LATE
YESTERDAY EVENING ACROSS ERN MO AND WEST CENTRAL IL AS THE
MID/UPPER LOW MOVED INTO SE MO AND THE TROF STARTED TO TAKE ON A
NEGATIVE TILT. STRONG DYNAMIC COOLING ALONG WITH MELTING HELPED
COOL THE LOW LEVELS BETWEEN AROUND 03-06Z...WITH A CHANGE TO A
RAIN/SLEET MIX AND THEN OVER TO SNOW. AFTER THE FINAL CHANGEOVER
THE SNOW CAME FAST AND FURIOUS WITH HIGH RATES AND BIG FLAKES...RAPID
COOLING THE GROUND ALLOWING FOR QUICK ACCUMULATIONS. DUE TO THIS
AND THE WET NATURE OF THE SNOW...AREA ROADS BECAME SLICK RATHER
QUICKLY. HIGHEST ACCUMS ACRS ERN MO THUS FAR HAVE GENERALLY BEEN
AROUND 3 INCHES GIVE OR TAKE A LITTLE...AND WHERE SNOW HAS ENDED
THERE IS ALREADY MELTING AND SETTLING OCCURING.

THE AXIS OF HEAVIEST SNOW WITHIN THE NORTH/SOUTH ORIENTED BAND
HAS MOVED INTO IL IN CONCERT WITH THE EJECTING MID/UPPER LOW NOW
MOVING INTO SRN INDIANA. WILL KEEP THE ADVSRY GOING IN SW IL THRU
12Z WITH AN ADDITIONAL 1-3 INCHES OF SNOW BY 12Z. LOW CLOUDS
EXTENDED BACK INTO CENTRAL MO AND THESE SHOULD CLEAR EWD PRETTY
QUICKLY WITH THE BACK EDGE IN SOUTHWEST ILLINOIS BY EARLY
AFTERNOON. THINK THE SNOW WILL BE GONE BY EVENING WITH THE HIGH
MARCH SUN ANGLE. WOULDNT BE SURPRISED IF THE WARMER MAV TEMPS
TURNED OUT OK...BUT SHAVED A FEW DEGS IN THE SNOW AREAS.

WEAK RIDGING WILL MOVE ACROSS TONIGHT WITH SELY SFC WINDS DEVELOPING
DURING THE OVERNIGHT HOURS.  HAVE ADDED SOME PATCHY FOG DUE TO THE
RAIN AND SNOW OVER THE LAST 24+ HRS.  BEST CHANCE WILL BE FROM ERN
MO INTO SRN IL WHERE THE WIND WILL BE LIGHTEST.

THE TROF CURRENTLY MOVING THRU THE PAC NW WILL AMPLIFY GREATLY OVER
THE NEXT 36H AS IT MOVES THRU THE GREAT BASIN AND ROCKIES. THIS NEXT
SYSTEM WILL BEGIN IMPACTING THE AREA MONDAY NIGHT. A NICE SWLY LLJ
RAMPS UP ADVECTING SOME DECENT MOISTURE INTO THE AREA. THIS IN
CONCERT WITH MODEST MID LEVEL LAPSE RATES RESULTS IN AN AXIS OF
ELEVATED INSTABILITY. THESE FACTORS COMBINED WITH GOOD LARGE SCALE
ASCENT ASSOCIATED WITH THE SHRTWV TROF SHOULD RESULT IN A BAND OF
SHOWERS AND SOME THUNDERSTORMS SPANNING THE FRONTAL ZONE MONDAY
NIGHT INTO TUESDAY MORNING.  NEWER MODEL GUIDANCE IS A BIT SLOWER
THAN THE PREVIOUS RUNS THUS HAVE BOOSTED THE POPS ON TUESDAY MORNING
ACROSS ERN MO INTO IL TO ACCOUNT FOR THIS.

THE ACTIVE PATTERN PERSISTS WITH YET ANOTHER SYSTEM LATE WED NIGHT
INTO THURS.
