...FREEZE WARNING IN EFFECT FROM 1 AM TO 10 AM CDT FRIDAY...

* WHAT...Sub-freezing temperatures as low as around 30 degrees 
  expected.

* WHERE...Nance, Howard, Merrick and Polk Counties.

* WHEN...From 1 AM to 10 AM CDT Friday.

* IMPACTS...Frost and freezing conditions could kill crops, other
  sensitive vegetation and possibly damage unprotected outdoor 
  plumbing.

* ADDITIONAL DETAILS...Although slightly sub-freezing temperatures
  are expected, a hard, killing freeze of 28 degrees or colder is
  fairly unlikely. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Take steps now to protect tender plants from the cold. To prevent
freezing and possible bursting of outdoor water pipes they should
be wrapped, drained, or allowed to drip slowly. Those that have
in-ground sprinkler systems should drain them and cover above-
ground pipes to protect them from freezing.

...FROST ADVISORY REMAINS IN EFFECT UNTIL 9 AM CDT THIS MORNING...
...FROST ADVISORY IN EFFECT FROM 1 AM TO 10 AM CDT FRIDAY...

* WHAT...For the Frost Advisory this morning, temperatures as low
  as mainly 32 to 36 degrees could result in areas of frost. For
  the second Frost Advisory for Friday morning, similar
  temperatures as low as mainly 32 to 36 degrees will likely
  promote areas of frost.

* WHERE...Portions of north central Kansas and south central 
  Nebraska.

* WHEN...For the first Frost Advisory, until 9 AM CDT this 
  morning. For the second Frost Advisory, from 1 AM to 10 AM CDT 
  Friday.

* IMPACTS...Frost could kill sensitive outdoor vegetation if 
  left uncovered.

* ADDITIONAL DETAILS...For the first Frost Advisory this morning,
  frost may not occur across the entire Advisory area. This is due
  to the combination of an area of low clouds drifting over parts
  of area, along with breezes holding up around 10 MPH in some
  places. For the second Frost Advisory for Friday morning,
  Although near-freezing temperatures are possible, a hard, 
  killing freeze of 28 degrees or colder is unlikely.
 
PRECAUTIONARY/PREPAREDNESS ACTIONS...

Take steps now to protect tender plants from the cold.
