...RECORD LOW TEMPERATURE FOR JULY 25 SET AT SIOUX CITY...
                                                                                
AT 451 AM CDT...THE TEMPERATURE AT SIOUX GATEWAY AIRPORT DROPPED TO
49 DEGREES.  THIS ESTABLISHES A LOW TEMPERATURE EXTREME OF RECORD
FOR JULY 25.  THE PREVIOUS RECORD LOW TEMPERATURE WAS 50 DEGREES...
SET WAY BACK IN 1891.
                                                                                
WITH OVER AN HOUR BEFORE SUNRISE AND ESTABLISHMENT OF WEAK COOL AIR
DRAINAGE WINDS FROM THE EAST...IT IS VERY POSSIBLE THAT THE
TEMPERATURE COULD DROP ANOTHER DEGREE OR TWO LOWER.
