In the western and central lakes, winds will shift and begin to blow from the northwest, promoting heavier snow farther south. 23. Later Wednesday night and Thursday, progressively colder air will circulate over the relatively tepid Great Lakes, setting the stage for heavier snow showers downwind of the lakes. 24. Narrow bands of heavier snow squalls will brush Cape Cod during the day. 25. Overnight, a band of heavier snow with this disturbance will expand across northern parts of Kansas and Missouri. 26. Patchy snow is expected in western parts of the northern Plains, with heavier snows in the higher elevations of the northern and central Rockies. 27. Some bursts of heavier snow are possible in the Ozark Mountains of Arkansas. 28. Unsettled weather will cover the interior West with valley showers and heavier snow in the northern and central Rockies. 29. But when Friday came, the weather was about the same with even heavier snow and persistent winds. 30. Cold temperatures had weakened the early snowpack, and heavier snow fell on top of that base, officials said. |
