Why the Frost Free countdown changed

As I myself was watching the days tick down in eager anticipation, I noticed the last few days that my usual goto site for dead basic weather information was noting frost advisories.  Then today, they vanished.

I just went back to the site to try to figure out what happened, and this notice is what I found:

…FROST/FREEZE HEADLINES DELAYED UNTIL APRIL 25TH…

The median date for the last spring freeze across coastal and southeast Massachusetts, Rhode Island and northern Connecticut is April 21st. This is typically when our office would begin to issue Frost Advisories and Freeze Warnings for these areas.

Based upon the abnormal cold in April, as well as coordination with our partners, we have decided to delay the issuance of Frost Advisories and Freeze Warnings until April 25th.

We currently expect overnight temperatures to threaten sensitive outdoor vegetation with a frost, or even a freeze, through at least this weekend.

So that is why I changed the countdown to the 25th.

Note: If you can’t figure out where the frost countdown box is, that’s because I changed the countdown to a garden project after the extended frost date had passed.
