4/10 - 4/11 Winter Storm (Update #4)

Snow continues over the state into the early afternoon hours, although some areas of eastern Iowa and southwestern Iowa may still be seeing rainfall at this time. Advisories/Warnings remain the same over the state, although total accumulations have been backed down some. The accumulations aren't taking place quite as quick as they thought, seemingly the soil temperatures have stayed just warm enough to keep snow from accumulating rapidly. Northern portions of the state will still be looking at 4-8 inches, however the central third may only be looking at 1-4 inches instead of the previously forecasted 3-6. The snow is expected to weaken by tonight, with western Iowa seeing the snow end by 10 PM, central Iowa by 1 am and by sunrise tomorrow the snow should be out of eastern Iowa as well.

Latest reports include Mason City with 5 inches, Forest City with 4 inches. Out of the FSD forecast area, areas including in the heavy snow warning report 6-7 inches this morning. Just north of the border, Jackson, MN reported 8 inches of snowfall. These amounts will likely increase this afternoon adding on a few more inches before snow ends.

Once this storm departs the area, we finish off the week with temperatures in the 30s and 40s for highs, 20s and 30s for lows. The previous mentioned system that might affect the area on Friday has trended well south and doesn't look to be much of a concern at the moment now. Once that system is completely out of the plains by Sunday, the warm air surges northward and our highs look to increase dramatically by next week. A better look ahead once this system has ended and moved on...
