Freeze Watch Issued For Friday Night
BOSTON (CBS) - As expected, the National Weather Service has issued a freeze watch for just about all the suburbs away from and along the coast Friday night into Saturday morning. The watch does not include Cape Cod.
Temperatures are expected to drop below 32 degrees just after midnight on Friday night and stay below freezing until a few hours after dawn Saturday.
This will kill many crops and sensitive vegetation but also help to kill many of the mosquitoes and ease concerns over EEE and West Nile Virus.

So if you have any potted plants outdoors, you should absolutely bring them inside for the night.
Many have asked the question what the difference is between a frost and a freeze.
A frost advisory is issued when temperatures are expected to drop near the 32 degrees mark and there is significant moisture in the air to form dew which then turns to ice crystals.
A freeze warning is issued during the growing season when surface temperatures are expected to drop below freezing over a large area for an extended period of time (several hours), regardless if frost develops or not.
This is much more damaging than a frost because the ice that forms on vegetation during a frost will work to actually protect the plant from falling to even lower temperatures.
Without the icy coating, during a freeze, vegetation is exposed to much lower temperatures, typically causing much more widespread damage.
