50 degree temperatures for the first time on the Cape this winter season, were in the calendar/met Spring season which started on March 1st, but official spring begins on March 20th.  Today, Tuesday, March 9th, 2021 is the first time I recall Chatham, MA reaching 50F+ temperatures, and there was no nipping wind.  The winds are light out of the southwest, I do not feel fog will be an issue tonight as temps drop off as is during the Spring months.  Again, winter could spread its wings for a short unsustainable day or two, but nothing suggesting a three plus day period.  Honestly, I believe winter weather is gone for SNE this year until November, and our hurricane season could be quite active and violent.
