OMAHA, Neb. (WOWT) -

FINAL UPDATE: Now that the snow and wintry mix have moved out of the area, here’s a sampling of snowfall totals! The cleanup begins.

2 PM Update: Snow is already beginning to taper off from west to east across the Omaha Metro. Heavy snow will continue for the next few hours in SW and Central Iowa. Freezing rain and sleet are likely causing slick roads and power outages in far southeastern Nebraska and northwest Missouri.

When will the snow wrap up today? Mallory Schnell WOWT is here with a First Alert update!

1 PM Snowfall Amounts:

Noon Update: Snowfall reports of 4 to 6 inches are widespread across the Omaha Metro as of Noon Tuesday. Just in the last hour, an additional 1 to 1.5 inches have fallen! Roads are partially to completely covered all across Nebraska and southwest Iowa. Dry air is moving in to places like Norfolk and Columbus, but we are also watching more moisture streaming in from the southwest. Along with the additional moisture, however, we’re getting more warmth as well! This warm layer is allowing freezing rain and sleet to mix in just south of Lincoln.

9:45AM Update: Snowfall reports in the metro are in the 3-4″ range and climbing. Heavier snow rates are likely to move in from the southwest the rest of the morning. 1.5″/hr are possible into early afternoon at times. Heavier sleet totals near 1″ are possible near the Kansas border in SE Nebraska into NW Missouri. Road conditions are incredibly poor all over the area as of now as well. They’ll likely worsen into the afteronon.

8AM Update: Several reports of 2-3 inches of snow around the metro with some 3-4″ reports west of town in Saunders and Platte county. Winter storm warnings have been expanded to include more of the area as the snow really has piled up quickly this morning. Road conditions around the Omaha metro went downhill quickly from 5am to 7am. Several crashes have causes traffic problems along I-80, I-680, and I-480 during the morning commute.

Tuesday is a FIRST ALERT DAY due to the significant snow accumulation expected and the possibility of icing to the south of the metro. Winter Storm Warnings and Winter Weather Advisories are in place today. There are several aspects to this system that I’ll break down here.

Snow that overspreads the area this morning will stick with us through the afternoon. The heaviest snow rates will likely be in the 10am to 2pm range over most of the area. We’ll gradually build toward that as the morning goes along though. When it is all said and done, 4 to 7 inches of accumulation is likely in the metro and much of the area. High amounts of 7 inches or more are likely in parts of Western Iowa. There may be another area of 7 inches or more of snow near Norfolk and west as well. I do expect the snow to wrap up as we approach 6pm and it moves east quickly.

Some icing is likely in the southern parts of our viewing area as well. Up to a quarter of an inch of ice is possible in the Falls City area and into NW Missouri. This could easily lead to power outages when combined with the lighter snow amounts that we area expecting there.

Southeast wind gusts are likely to reach 30 mph at times as well so we could see some blowing and drifting snow as the day goes along.
