January Thaw - fact or myth?
FROM TODAY'S PRINT EDITIONS:
Rosi McCloskey, in Stewartstown, Pa., asks: “Is the ‘January thaw’ an actual annual occurrence, or just wishful thinking?”
Maybe both. Stats for the Northeast do show a warm temperature “singularity” around Jan. 20-25. It’s about 6 degrees in Albany, N.Y. But no plausible physical mechanism has been found to explain it.
A Cornell study found the oddity to be “well within the limits of what might be expected to occur by chance alone.” There are other such singularities in the stats, warm and cool. Europeans watch for the “Ice Saints” – a cold spell May 11-14.
