SATELLITE ANALYSIS AND TRENDS...MAIN UPPER LEVEL SEMI-CIRCULATION CENTER
AS PER LATEST GOES WATER VAPOR AND SATELLITE WINDS WAS CONTINUE TO DIG
SOUTH TOWARD THE IA-MO BORDER IN RESPONSE  TO GIANT BROAD FLAT RIDGE
ACROSS BRITISH COLUMBIA.    IMPORTANT FEATURES FOR SNOW WAS DEFORMATION
SLOWLY DRIFTING SOUTH OR RE-EVOLVING FURTHER SOUTH ACROSS E CENTRAL/SE
IOWA INTO NW ILLINOIS AND EXPANDING EAST AND SE.  WHAT THIS DIGGING AND
DEEPENING TROUGH WAS DOING WAS TAPPING MAX PRECIPITABLE WATER MOISTURE
CENTERED
SOUTHERN  MISSOURI AND ILLINOIS AND CONVEYOR BELTING IT INTO THE
DEFORMATION FOR MAX SNOW PRODUCTION EFFICIENCY WITH CURRENT BORDERLINE
SURFACE TEMPS AND ALOFT TO 850MB.    SO THERE IS A CONSTANT BATTLING
OUT BETWEEN THE DEEP MOISTURE BEING THROWN INTO THE COLDER AIR OF THE
DEFORMATION AT THE SAME TIME DRIER AIR FROM MINNESOTA...WISCONSIN AND
TO A LESSER EXTENT NW IOWA SETTLE SOUTH AND SE.
.
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 1530-1830Z...MEDIUM CONFIDENCE FACTOR
IN SHORT TERM OUTLOOK...SNOW WILL CONTINUE TO EVOLVE WITH BEST
DEFORMATION AND INTO ENOUGH COLD AIR AND FORCED MOISTURE TRANSPORT.
BELIEVE STEADIEST AND HEAVIEST SNOW WILL SHIFT ESE AND SE FROM CURRENT
E CENTRAL TO INTERIOR SE IOWA AND NW ILLINOIS. BUT IT WILL ALSO BE AN
INCREASING CLASH OF COLDER AND DRIER AIR NORTH WITH WARMER AND MORE MOIST
AIR TO THE SE WHICH WILL MAKE IT DIFFICULT TO JUDGE TIMING OF RAIN CHANGE
OVER TO SNOW AND EXACT AREA OF HEAVIEST ACCUMULATING SNOW THIS PERIOD.
SEE GRAPHIC THAT WILL  BE SENT TO HOME PAGE SHORTLY.  SEE LATEST WPC
SNOW DISCUSSION AND GRAPHIC FOR ADDITIONAL DETAILS.
