Weekend Snowstorm (Final Report)

This will begin the ‘LIVE’ updates on snowfall over the area, currently I’m in northwest Iowa (Terril) and the snow began just over an hour ago. Accumulations have been fairly light, although a 1/2 inch of snow in the past hour with mainly flurries is kind of impressive. Snow Advisories have been posted for all of the Sioux Falls CWA, while areas within the Des Moines CWA have been posted under a Snow & Blowing Snow Advisory. Both of those last this afternoon through the early morning hours or tomorrow when winds will begin to pick up after the snow has stopped.

So, as of 2 PM:

16 degrees
Light snow
Winds: Light to 5 mph
Total Accumulations: 1/2 Inch (1/2 Past Hour)

————————————————————————————–

3:30 PM Update:

Winter Storm Warning Issued for portions of Northern Iowa. Details Here

Light Snow
16 Degrees
Northerly Wind 0-8 mph
Visibility: 1/2 Mile
Total Accumulations: 1 3/4 Inches (3/4 Inch an Hour Average)

————————————————————————————–

4:30 PM Update:

Light Snow
15 Degrees
Northerly Winds 0-10 mph
Visibility: 1 Mile
Total Accumulations: 2 Inches

Dry pocket of air seemingly is decreasing some of the snowfall in portions of the area, looks as though light snow if that over the next hour or so here. More snow is beginning to fill in over NE and expect this to continue into the night where most of the snow will fall later tonight… Next update will likely not be until 8 PM or so as I’m heading out away from computer.

FINAL UPDATE:

Areas across northwest Iowa varied in snow totals dependent on the location of the snowbands that setup across much of the state giving localized higher amounts in some areas. 6 Inches of snow is the final measurement that was made on Monday morning and will be the storm total amount in Terril, Iowa. The winds did not increase as much as anticipated and thus the blowing snow wasn’t as bad as forecasted. Still roadways were somewhat of a hassle to travel on early on Monday and even into the day on Tuesday some roads were snowpacked and slippery in the cities. This system still left the area with a good snow that finally has stuck around for a while, this also gave some areas of Iowa their first significant snow of the season.
Behind this snow came the arctic air however, with lows on Tuesday morning dropping well below zero across Iowa, Nebraska and several other states. The lowest report in Iowa was -24 degree in LeMars, with several other areas in northwest Iowa in the high teens below zero to other 20-some degree marks in the red. Temperature are slowly warming in response to south winds, however even in the south temperatures are near or below freezing and thus no major warmup is expected.
