SATELLITE ANALYSIS AND TRENDS...WV LOOP SHOWS DISTINCT QUICK MVG LOBE
OF VORTICITY HAS BEEN STRETCHING SW TO NE ACROSS THE CENTRAL MS VALLEY
CONTINUING TO DEEPEN THE TRIPLE POINT.  CONSEQUENTLY MAIN VORT CENTER OVER
C IL HAS REMAINED RELATIVELY STATIONARY WITH NE DRIFT AND  WITH INFLUENCE
OF NWLY FLOW FROM CANADA IS LEADING TO STRETCHING TOWARD THE S PORTION OF
LK MI.  CONVEYOR BELT IS WELL DEFINED IN VIS/IR LOOP WITH FLOW WRAPPING
BACK WEST THEN SW INTO THE CENTER INCREASING MOISTURE AVAILABILITY FOR
SNOW GROWTH.  VIS SHOWS CONVECTIVE ELEMENTS ALONG THE BELT ACROSS NE IL
THOUGH LOW LEVEL PROFILES ARE STILL QUITE DRY AND NEED TO MODIFY WITH
WITH EVAPORATIVE COOLING THAT THESE MIDLEVEL ELEMENTS WILL PROVIDE.
NEAR THE CENTER THE ENVIRONMENT NEAR SFC IS ALREADY SUPPORTIVE AND HAS
DONE WELL TO PROVIDE TOTALS OF 2-4" SO FAR WITH CONTINUED 1-1.5"/HR
RATES...HOWEVER RECENT VIS LOOP SHOWS SOME CONVECTIVE FEATURES WITHIN
THE STRATUS DECK EXTENDING ALONG AN APPARENT TROF THAT EXTENDS FROM
THE CENTER WNW TO THE RIVER INTO DES MOINES COUNTY IA.  THESE CURRENTLY
ARE ISOLATED THOUGH EXPANDING AND WILL LEAD TO VERY LOCALIZED BANDS OF
SLIGHTLY HEAVIER SNOW RATES ACROSS SW WARREN, E DES MOINES, AND CENTRAL
FULTON COUNTIES.  PLEASE SEE GRAPHIC WITH VIS IMAGE AT WEB ADDRESS BELOW.
