>  ...POTENTIAL WINTER STORM TO AFFECT NORTHEAST IOWA LATE
>  SATURDAY INTO SUNDAY...
>
>  A VIGOROUS UPPER LEVEL STORM SYSTEM MOVING THROUGH THE NORTHERN
>  ROCKIES...WILL DIVE SOUTHEAST ACROSS THE MIDDLE
>  MISSISSIPPI VALLEY LATE SATURDAY. ALTHOUGH DEEP MOISTURE WILL BE
>  LACKING WITH THIS SYSTEM...STRONG DYNAMICS AND MARGINAL
>  MOISTURE WILL BE MORE THAN SUFFICIENT TO GENERATE PRECIPITATION
>  OVER THE REGION. THE PRECIPITATION IS EXPECTED TO
>  DEVELOP LATE SATURDAY AFTERNOON AND CONTINUE INTO SUNDAY BEFORE
>  ENDING FROM WEST TO EAST. WARM AIR BEING BROUGHT NORTHWARD AHEAD OF
>  THE STORM SYSTEM...WILL ENSURE THAT ANY PRECIPITATION LATE SATURDAY
>  AFTERNOON WILL FALL AS RAIN. HOWEVER...AS THE STORM SYSTEM NEARS...
>  AND EVENTUALLY PASSES JUST TO OUR SOUTH...THE RAIN WILL EVENTUALLY
>  MIX WITH AND CHANGE OVER TO SNOW FROM NORTHWEST TO SOUTHEAST. THIS
>  CHANGE OVER WILL BEGIN AROUND MIDNIGHT...ALONG AND NORTHWEST OF A
>  LINE FROM WILLIAMSBURG...TO CEDAR RAPIDS AND DUBUQUE. THE CHANGE OVER
>  WILL THEN PROGRESS EASTWARD OVER THE REST OF THE REGION
>  DURING THE EARLY MORNING ON SUNDAY. AT THIS TIME...IT APPEARS THE
>  BEST POTENTIAL FOR SIGNIFICANT SNOW ACCUMULATIONS WILL BE ALONG
>  AND NORTHWEST OF A CEDAR RAPIDS...TO DUBUQUE LINE WHERE THE CHANGE
>  OVER WILL BE EARLIEST TO OCCUR. IN THESE AREAS...SNOWFALL
>  ACCUMULATIONS OF 2 TO 5 INCHES...WITH LOCALLY HIGHER AMOUNTS WILL BE
>  POSSIBLE...BEFORE DIMINISHING EARLY SUNDAY. SNOWFALL ACCUMULATIONS
>  ELSEWHERE...WILL BE LIGHTER...AND GENERALLY AROUND AN INCH
>  OR TWO ALONG AND NORTHWEST OF A KEOSAUQUA...TO PRINCETON LINE.
>
>  A STRONG PRESSURE GRADIENT WILL BE DEVELOPING LATE SATURDAY NIGHT
>  AND SUNDAY. THIS WILL RESULT IN STRONG NORTHWEST WINDS...WITH
>  GUSTS OF NEAR 40 MPH POSSIBLE. THIS WILL CAUSE CONSIDERABLE BLOWING
>  AND DRIFTING OF THE FRESHLY FALLEN SNOW...CREATING
>  HAZARDOUS TRAVEL CONDITIONS. THE POTENTIAL EXISTS FOR NEAR BLIZZARD
>  CONDITIONS ALONG AND NORTHWEST OF A CEDAR RAPIDS...TO DUBUQUE LINE.
>  THUS...A WINTER STORM WATCH HAS BEEN ISSUED FOR THESE AREAS
>  SATURDAY NIGHT THROUGH EARLY SUNDAY.
