... Freeze warning in effect from midnight tonight to 7 am CDT
Friday...

The National Weather Service in Green Bay has issued a freeze
warning... which is in effect from midnight tonight to 7 am CDT
Friday.

* Low temperatures of 25 to 30 degrees are expected across most
of the area tonight. Some of the climatologically cold spots
could have temperatures drop to near 20 degrees.

* The sub-freezing temperatures will last for several hours...
resulting in a hard freeze. This will likely kill any cold-
sensitive vegetation.

* Frost will be possible Friday night even though temperatures
then will not be as cold as those expected tonight.

Precautionary/preparedness actions...

A freeze warning means sub-freezing temperatures are expected.
Cold sensitive vegetation that is left unprotected will likely be
killed. If possible... shelter any cold-sensitive plants in a
garage or shed overnight. If that is not possible... cover the
plants with a tarp or cloth.

... Record low temperatures possible Friday morning (may 24th)...

Unseasonably cold temperatures are expected Friday morning with
low temperatures in the 20s north and lower to middle 30s over
the remainder of the area.

Here is a list of record lows for Friday (may 24th).
