Hard Freeze Warning in effect from midnight tonight to 9am CST Friday.

* A very cold arctic air mass has settled across the region. Temperatures will fall into the teens before daybreak across much of Northeast Texas, Southeast Oklahoma and all of Southwest Arkansas.

* Impacts:  These extremely cold temperatures will persist through the early morning hours before slowly climbing into the 20's by mid morning.  Residents should take precautions to protect water pipes, pets & plants from these very cold conditions.

A hard freeze warning means sub-freezing temps are imminent for several hours tonight.  This will place great stress on persons without adequate heat.  Check on your elderly neighbors to make sure they have heating during this extended cold.
