EVENT...JET, UPPER LEVEL SHORT WAVES...DEEP MOISTURE CLASH WITH COLD/DRY
AIR...ALL THE MAKINGS OF SIGNIFICANT SNOWS CENTERED ON CENTRAL MO THROUGH
CENTRAL ILLINOIS INTO N HALF OF INDIANA...
.
SATELLITE ANALYSIS AND TRENDS...BIG PICTURE STARTING TO DRIVE THE SMALLER
SCALE AS WELL DEFINED SW TO NE ORIENTED MOISTURE PLUME OR CONCENTRATION
OF HIGHEST MOISTURE WAS CENTERED FROM THE TX-MEXICO GULF OF MEXICO
COAST TO THE TEXAS-LOUISIANA BORDER TO EASTERN ARKANSAS INTO WESTERN
TN AND KENTUCKY. DRY/LOW PWAT AIR NOT TOO FAR AWAY AND SHIFTING SLOWLY
EAST AND SE ACROSS IOWA AND NORTHERN/WESTERN MO. SO THAT IS THE FIRST
CLASH THAT IS CREATING A SHARP INSTABILITY GRADIENT THAT CAN CERTAINLY
HELP PRECIPITATION GENERATION AND IN THE COLD AIR SNOW PRODUCTION.
WELL DEFINED JET FROM MANITOBA-ALBERTA BORDER SOUTH THROUGH WESTERN
WYOMING AND COLORADO AND N/C NEW MEXICO WAS HOOKING UP WITH SUBTROPICAL
JET ACROSS S NEW MEXICO...NORTHERN TEXAS AND ACROSS C ARKANSAS INTO
WESTERN KY AND SOUTHERN ILLINOIS. MAIN UPPER LEVEL FORCING FEATURE THAT
CAME OUT OF COLORADO LATER YESTERDAY AND NOW MOVING ACROSS C KANSAS
HAD VARIOUS SUBTLE SHORT WAVE IMPULSES OUT AHEAD ACROSS MISSOURI AND
ILLINOIS THAT WAS HELPING TO INTERACT WITH JET TO THE SOUTH AND SLIGHT
DIFFLUENCE CENTERED ON MISSOURI AND DEEP MOISTURE E TX TO MISSOURI TO
PRODUCE STEADY LIGHT TO MODERATE/OCCLY HVY RAIN SOUTH..IE MOST OF ARKANSAS
AND SOUTHERN ILLINOIS AND SE MISSOURI AND LIGHT TO MODERATE/OCCLY HVY
SNOW NORTH...IE MOSTLY CENTRAL MISSOURI...C ILLINOIS INTO C INDIANA.
WITH CORE OF HEAVIEST SNOW FOLLOWING CLOSE TO THE PATH OF THE 850MB
LOW NEAR S CENTRAL/C MISSOURI INTO C ILLINOIS. NESDIS SNOWFALL PRODUCT
EARLIER WERE GIVING MAX SNOW-WATER EQUIVALENT (SWE) RATES OF 0.04"/HR
CENTERED ON NE AND S CENTRAL MISSOURI EARLIER THIS MORNING AROUND 1030Z
AND IR TRENDS WOULD SUGGEST A SLIGHT INCR IN SWE SINCE THAT TIME WHICH
COULD TRANSLATE INTO GENERAL 0.5"-1.0"/HR SNOW RATES AND OCCL 1.5"/HR
RECENTLY CENTERED E CENTRAL MISSOURI THROUGH CENTRAL ILLINOIS AND ACROSS
PORTIONS OF CENTRAL INDIANA WITH INCREASED INTERACTION OF FORCING AND
COLD/DRY VS MILD/MOIST CLASH.
.
AN ANNOTATED SATELLITE GRAPHIC SHOWING THE HEAVY PRECIPITATION
THREAT AREA SHOULD BE AVAILABLE ON THE INTERNET ADDRESS LISTED
BELOW IN APPROXIMATELY 10-15 MINUTES.
.
SHORT TERM OUTLOOK VALID 1415-1800Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...BAROCLINIC SATELLITE WINTER STORM SIGNATURE
LOOKING BETTER PAST FEW HRS AND USUALLY HIGHEST PRECIP FALLS ON SOUTHERN
EDGE OF ENHANCED COOLER CLOUD TOPS WITH HEAVIEST SNOW FALLING ALONG PATH
OF 850MB LOW AND CLOSE TO THE -5C 850MB TEMP AND THAT SHOULD CONTINUE TO
BE E CENTRAL MO THROUGH CENTRAL WORKING INTO INTERIOR NORTHERN ILLINOIS
AND INDIANA WITH SNOW RATES UP TO 1"/HR WITH OCCASIONAL HIGHER RATES OF
1.5"-2.0"/HR CENTERED NEAR STL LOUIS...C ILLINOIS (SOUTH OF CHICAGO)
INTO C INDIANA CLOSE TO OR JUST NORTH OF INDIANAPOLIS. FOR REFERENCE.
IMPRESSED WITH ANOMALOUS NATURE OF HIGH MOISTURE COMING IN FROM E TX/LA
AND ARKANSAS AND CLASHING WITH LOW TO MODERATE MOISTURE ILLINOIS AND
UPPER MIDWEST, SO THAT THERE COULD BE SNOW RATES OCCLY INCREASING TO
MORE THAN 2"/HR AS THIS PERIOD GOES ON IN SNOW AREA OUTLINED JUST ABOVE.
