Hot weather now presages a hard Winter.

[Silver Tabby]

"Signs of Hot Weather - many bats flying abroad sooner than ordinary; A white mist arising out of moors or waters, either before Sun rising or after Sun setting. Birds flying high in the air. Crows and Ravens gaping against the Sun. Store of flies playing in the Sun shining towards night."
Almanack 1633

No global warming in those days.
