Snowstorm (Feb. 12/13)

The snowstorm that has been forecasted, but hard to pinpoint is finally arriving in the plains. Areas of South Dakota saw fairly heavy snow this morning and into the early afternoon today, with this snow continuing to move to the east/southeast into MN/IA. Also we should watch the wrap-around moisture and thus precipitation that will come into parts of Iowa and other portions of the plains tonight. This post is forecasted mainly on Iowa as there is plenty to cover with 4 different Winter Weather Advisories/Warnings out there. The northern half of Iowa should mainly be concerned with the northern wave of snow coming out of South Dakota. The southern half will see much of the wrap around moisture from the strong low pressure system located in the southern plains. The heaviest snow is likely to fall in southeastern quarter of the state where the wrap around will be heaviest, while the lightest snows will probably fall in western Iowa. Here are the latest issuances for the state:

Snow Advisory -- Northwest Iowa (West of Hwy 4 & North of Hwy 20)
Winter Weather Advisory -- Southwest Iowa (West of Hwy 71 & South of US 20)
Winter Storm Warning -- Southeast Iowa (East of I35 & South of US 30)
Snow & Blowing Snow Advisory -- (Remainder of Iowa)

My Forecasted Snow Totals:

Sioux City, IA: 3-6 Inches
Spencer, IA: 3-6 Inches
Omaha, NE: 2-5 Inches
Mason City, IA: 3-7 Inches
Ames, IA: 5-8 Inches
Des Moines, IA: 5-8 Inches
Waterloo, IA: 4-7 Inches
Cedar Rapids, IA: 4-7 Inches
Dubuque, IA: 4-7 Inches
Burlington, IA: 6-10 Inches
