AN UPPER LEVEL DISTURBANCE OVER THE PACIFIC OCEAN WILL TRACK INTO
NORTHERN MEXICO TUESDAY MORNING AND THEN TURN NORTHEAST ACROSS
EASTERN OKLAHOMA TUESDAY NIGHT. A PERIOD OF SNOW IS EXPECTED WITH
THIS SYSTEM TUESDAY NIGHT AND EARLY WEDNESDAY. SNOWFALL OF 1 TO 3
INCHES IS POSSIBLE. AT THIS TIME NORTHEAST OKLAHOMA IS THE MOST
LIKELY AREA TO RECEIVE THE HIGHER AMOUNTS OF SNOW. HOWEVER THIS
SYSTEM IS OUTSIDE THE U.S. OBSERVATION NETWORK AND THIS LEADS TO
EXTRA UNCERTAINTY ABOUT THIS SYSTEM. SO CHANGES IN THE SNOW
AMOUNTS AND PLACEMENT OF THE SNOW WILL LIKELY OCCUR AS LATER
INFORMATION BECOMES AVAILABLE.
A SECOND UPPER LEVEL DISTURBANCE IS EXPECTED TO RACE ACROSS THE
AREA ON THURSDAY FROM THE NORTHWEST. THIS SYSTEM WILL ALSO BRING A
CHANCE OF SNOW TO THE AREA.
EMERGENCY MANAGEMENT PLANNING STATEMENT...
WHILE THE APPROACHING DISTURBANCES ARE NOT LIKELY TO BECOME MAJOR
STORMS...THEY COULD PRODUCE ACCUMULATING SNOWS. EMERGENCY MANAGERS
SHOULD FACTOR IN THE POSSIBILITY OF ADDITIONAL SNOW AS THEY
CONTINUE DEAL WITH THE AFTERMATH OF THE CHRISTMAS EVE STORM.
