Cleaning up the backyard now that temperatures have soared into the upper 50s F/15 C, and I noticed that the snow cover evidently protected these volunteer (invasive) motherwort plants (Leonurus cardiaca) from the bitter cold of -7 F/-22 C of just one week ago.

The #ArcticBlast over #NorthAmerica is truly extreme. At the 850-hPa level, we are in the range of the 0.5% percentile of the climate mean, if you look at the GFS analysis. At the 2m #Temperature, the IFS forecasts a -6 to -10 degree deviation from 1% (!) percentile for today (12Z). These are anomalies we never see in Europe and which I have rarely seen for North America.

This was a very thundery day today in the area of the western #Mediterranean. A prominent line of #thunderstorms formed off the #BalearicIslands from the morning hours, which moved southeastward over the archipelago during the day. Per hour up to 5,000 #lightning #strikes and a total of more than 25,000 lightning strikes were registered throughout the day.
The #storms brought heavy rain and gale-force winds.
