Winter Storm: Feb. 7/8 Update #4

A quick update with a look at a surface chart with contoured and color-filled gradient of surface temperatures, as well as 10-meter wind speeds overlayed.  Can you tell me where the upper-low, cold front, and occlusion is occurring?  A pretty impressive surface map with temperatures dropping like a rock across parts of northwest Iowa and adjacent areas, Spencer recorded a temperatures of -19 back at 8PM.  These temperatures will slowly rise through the night as the low pressure overhead moves eastward and northwest winds actually advects warmer air into the area!

I'll post an additional update later on tonight or early tomorrow with some of the snow totals, currently it would look as if parts of eastern Iowa and Minnesota won the snow battle with 6-10" in that area. Portions of Missouri and Kansas were able to get into the 3-6" range with a few isolated higher amounts in southern Kansas. Parts of northern Arkansas also won the snow big with a few reports over 6" being received as well. This snow will continue over parts of eastern Iowa, Minnesota, Missouri and other adjacent areas. More details on snow totals later...  For now enjoy the fancy image below:
