There is a terrifying storm organizing in the southeast, prepared to move up the eastern Seaboard. We will discuss it throughout the next couple of days in the forum, so stop in for updates. Our forecast today takes us to a much more hospitable location. What do the next two days hold?
At 1053AM, CT, Ames was reporting a temperature of 17 degrees with mostly sunny skies. The area saw snow overnight and into the morning, and the band was still seen on radar, from Marshalltown to Des Moines and points southeastward, but safely out of Ames for the day.
Ames is within a sharp upper level trough, and at its base lies the crippling winter storm rising out of the Gulf of Mexico. Flow through the western leg of the trough is fairly weak, but a laminar jet leading into the trough is strong, giving rise to another clipper emerging out of the Canadian Rockies. It will sweep through the Upper Midwest overnight tonight sending a quick burst of cold air into Iowa, with the boundary stalling just south of town. This shouldn’t generate much if any snow in Ames, as most Gulf moisture is still being drawn towards the tremendous coastal winter storm, and temperatures are going to be near freezing. As noted, however, the boundary will stall in southern Iowa. As the more impressive system lifts northeast, the Gulf will open up, and the chances for snow will increase again over Iowa, however by this point, heavy precipitation is very unlikely.

I don’t think it will be too bad in Ames. The warm up is leading to model projections of a little bit of ice mixing in, but that is clearly not the common opinion among forecasters. Here is the radar showing snow skipping out of town.
