UPDATE TO COME OUT SHORTLY TO REDUCE SNOW AMOUNTS A LITTLE...BUT
WILL BE LEAVING ADVISORY IN PLACE.  THIS SYSTEM IS A RELATIVELY
VIGOROUS...BUT HAVE CONCERNS ABOUT THE AMOUNT OF DRY AIR BEING
ENTRAINED INTO THE WARM SECTOR OF THIS SYSTEM...AND HOW FAR SOUTH
THE 850 LOW IS SWINGING.  ALSO...LOW LEVEL FLOW OVER THE CWA IS FROM
THE NORTHEAST...WHICH IS CHARACTERISTICALLY VERY DRY AND REALLY
KNOCKS DOWN SNOW AMOUNTS.  HOWEVER...HAVE JUST GOTTEN SOME RELIABLE
REPORTS OF SNOW ALONG THE IA/MO BORDER...WITH AS MUCH AS 1 INCH ON
THE GROUND.  SNOW ACCUMULATIONS UNDER THE MAIN SNOW BAND ALONG THE
IA MO BORDER AS IT EXTENDS BACK TO THE WEST ARE BETWEEN 4 AND 5
INCHES...AND WITH THE SYSTEM LOSING STRENGTH THAT SHOULD BE THE MOST
WE COULD EXPECT ACROSS THE SOUTHERN PARTS OF OUR CWA.

OTHERWISE...NOT MUCH MORE THAN SOME COSMETIC TWEAKS.
