NWS STORM PREDICTION CENTER NORMAN OK0534 PM CST WED NOV 21 2007 AREAS AFFECTED...ECNTRL IA...SRN WI...EXTRM NRN IL
CONCERNING...HEAVY SNOW
SNOWFALL RATES OF 1 INCH PER HOUR AND ISOLATED AREAS OF UP TO 2
INCHES PER HOUR DURING EARLY EVENING WITH SNOWFALL RATES GRADUALLY
DIMINISHING.
EXPECT STRONG MOIST ASCENT TO CONTINUE ACROSS THIS AREA ALTHOUGH AS
THE UPPER SYSTEM LIFTS NORTHEASTWARD ACROSS THE AREA...EXPECT
SNOWFALL RATES TO GRADUALLY DIMINISH DURING THE EARLY EVENING AS
INDIVIDUAL BANDS OF SNOW END FROM WEST TO EAST.
THIS FAVORED AREA OF STRONG MOIST ASCENT IN THE DENDRITE GROWTH
REGION SHOULD PRODUCE SOME AREAS OF HEAVIER SNOWFALL...HOWEVER...
WITH THE UPPER SYSTEM ACCELERATING TO THE NORTHEAST ACROSS THIS
AREA...MOST OF THE HEAVIER SNOWFALL SHOULD BE ENDING BY MID EVENING.

what does he mean when he says that expect snowfall rates to diminish through the evening hours?
The rate at which the snow falls determines how much snow will accumulate. For instance, the band of snow now pushing through Freeport will produce 1-2" based on the snowfall rate. However once that goes through, we're done. -ES
