We had some interesting weather in the St. Louis area today. As the sun heated the surface under very cold air aloft, convection occurred. While driving in the St. Louis area today, I encountered several bursts of frozen precipitation mixed with rain. Hard to categorize it - kind of a mix of wet snow and sleet or soft hail. Probably graupel would be the best catch-all term for it. Judging from short term forecasts issued by NWS offices, weather of this type occurred over much of Illinois and eastern Missouri today - even a few lightning strikes in the Chicago area, northwest Indiana, and southeast of St. Louis.
Kind of early for frozen precipitation in this area (other than hail from summer thunderstorms, but this was different from that).
