There's a storm coming, which may bring some mix of rain, snow, sleet, freezing rain, and ice pellets to Ann Arbor. The worst of it will be on Wednesday, March 23 2011, the date of the Roman festival of Tubilustrium. This event was held in honor of Vulcan, the god of fire and metal working.
Some charts, graphs, maps etc.
The Weatherspark forecast has a nice spark-line style chart interface; this is an excerpt from the full page. The graphic is used under the generous licensing terms from Weatherspark, which reads "Please don't abuse the service."
The 48 hour forecast ice accumulation composite show the chance of ice accumulations more than 0.25 inches; this from the Hydrometeorological Prediction Center.
The three-day cumulative precipitation forecast makes it pretty clear we're going to get some kind of weather, but if you squint you can make the difficulty of a precise forecast clear. Depending on a few degrees change in temperature, Ann Arbor and the area could get mostly rain, mostly snow, some nasty ice or the dreaded "wintry mix".
Your recipes are welcome for the "wintry mix" portion of this forecast.
