FORT WORTH (CBSDFW.COM) – Temperatures will drop below freezing again for North Texas as clear skies and light winds will make for good radiational cooling.  That is when the heat from the day easily radiates away from the ground toward space.  This makes for a cold night.

There is a FREEZE WARNING in effect again for parts of North Texas.  Let me explain why.  The Freeze Warning is in effect for Ellis, Kaufman, Hill County and counties south and east of them.  These areas did not see a freeze this morning.  Dallas and Tarrant County which will see temperatures drop below freezing tonight as well, are not included in the freeze warning.

The reason Dallas and Tarrant County are not included is because this morning temperatures did drop below freezing.  The policy of the National Weather Service is that a freeze warning will only be issued for the first freeze of the season.  After the first freeze is recorded no more freeze warnings will be issued for additional sub-freezing nights.  This leads to the problem we face today with half of our counties under a freeze warning, yet all areas will be below freezing.

Sunny skies on Saturday with temperatures a little warmer with highs in the low 60s.  An area of low pressure will strengthen on Sunday in Colorado.  This will increase the winds here out of the south.  It will be windy with partly sunny skies on Sunday with a high temperature of 66.

Scattered showers will arrive Sunday night ahead of another strong cold front.  The front will pass thru on Monday and scattered showers and storms will be possible.  Temperatures will crash once again behind the front Monday night.  Tuesday and Wednesday morning we will see temperatures near or below freezing with highs in the 50s.
