07:28 – Thanks to Lynn McGuire for the link to the following image.

As usual, xkcd gets the science right. The purple stain in the first panel is Hucker’s crystal violet, the primary stain used in Gram staining, and all of the presents are stained purple. The pink stain in the second panel is safranin O, used as the Gram counterstain. All of the presents have had the purple stain washed away, and are pink, indicating that these are Gram Negative presents.

09:20 – It appears that we won’t get much in the way of severe weather. As of yesterday morning, the forecasters were calling for heavy thunderstorms and possible tornadoes around here today, but now they’ve downgraded that to heavy rain and stiff winds. It’s about 39F and raining now, with wind gusts to around 25 MPH, but it seems likely that’s the worst we’ll get.
