SPECIAL WEATHER STATEMENT...CORRECTION

...WINTRY PRECIPITATION POSSIBLE IN PARTS OF EASTERN OKLAHOMA
   THIS EARLY MORNING...

RAIN WAS SPREADING BACK TOWARD NORTHEAST OKLAHOMA THIS MORNING
AHEAD OF AN UPPER-LEVEL DISTURBANCE MOVING NORTH OUT OF MEXICO.
AT THE SAME TIME COLDER AIR WAS MOVING INTO NORTHEAST OKLAHOMA
FROM THE WEST.  THIS RAISES THE POSSIBILITY THAT FREEZING RAIN
MAY DEVELOP IN PARTS OF THE AREA THIS MORNING.

NO ADVISORIES ARE BEING ISSUED AT THIS TIME BECAUSE DRIER AIR IS
ALSO MOVING INTO NORTHEAST OKLAHOMA WITH THE COLD AIR AND THIS
MAY KEEP ANY SIGNIFICANT PRECIPITATION FROM REACHING THE BELOW
FREEZING AIR.  IF THE RAIN DOES DEVELOP IN THE COLDER AIR THEN
ADVISORIES WILL BE NEEDED.
RADAR SUMMARIES AND LOCAL CONDITIONS BROADCAST HOURLY ON NOAA
WEATHER RADIO...ON 162.55 MHZ IN THE TULSA AREA...WILL DETAIL THE
LATEST INFORMATION.

PERSONS PLANNING TRAVEL IN NORTHEAST OKLAHOMA SHOULD LISTEN FOR
FURTHER STATEMENTS FROM THE NATIONAL WEATHER SERVICE.
