This must be the Equinoctial Storm.

Did not go out this evening, the walking was too bad, and I felt too dull and sleepy.

According to the American Meteorological Society website an equinoctial storm (also known as a line storm or line gale) are “severe storms in the United Kingdom and North America that are popularly believed to accompany the vernal and autumnal equinox.”  While there is no statistical evidence to support this belief, it may have come about by sailors associating hurricanes in the West Indies with the autumnal equinox and then by extension, people believed severe storms occurred at the vernal equinox as well.
