STRONG COLD FRONT ROUGHLY ALONG A MIAMI/TULSA/OILTON LINE THIS MORNING.  
SHOWERS WITH SCATTERED THUNDERSTORMS HAVE INCREASED SOME IN AREAL  
COVERAGE ACROSS NE OK THIS MORNING JUST AHEAD AND BEHIND THE BOUNDARY.  
AREAL COVERAGE OF SHOWERS AND STORMS WILL TRANSLATE EAST AND SOUTHEAST  
WITH THE FRONT AS IT MOVES THROUGH THE REMAINDER OF THE AREA THIS  
MORNING. SHARPLY COLDER AIR WILL FILTER IN THROUGHOUT THE DAY,  
WITH SOME TEMPERATURE RECOVERY EXPECTED THIS AFTERNOON AS ACTIVITY  
ASSOCIATED WITH THE FRONT WILL BE SOUTHEAST OF THE AREA. COOL BUT  
DRY WEATHER EXPECTED SATURDAY AS HIGH PRESSURE BEGINS TO SLIDE  
EAST. SOUTH-SOUTHEAST WINDS RETURN SUNDAY AHEAD THE NEXT FRONT  
WHICH WILL BRING A SHOT OF EVEN COLDER AIR TO START THE NEXT WORK  
WEEK. THIS FRONT WILL MOVE THROUGH LATE SUNDAY AND SUNDAY NIGHT  
AND WILL BRING CHANCES FOR RAIN AND ISOLATED TO SCATTERED  
THUNDERSTORMS. MAGNITUDE OF THE COLD AIR IS STILL IN QUESTION,  
WITH THE GFS STILL THE COLDEST OF THE LONG RANGE MODELS. HAVE  
OPTED TO SIDE WITH THE WARMER SOLUTIONS, BUT TEMPERATURES ARE COLD  
ENOUGH ACROSS PARTS OF FAR NE OK TO WARRANT A MENTION OF SLEET AND  
FREEZING RAIN FOR EARLY NEXT WORK WEEK. AIRMASS LOOKS TO MODIFY  
TOWARDS THE MIDDLE OF THE WEEK AS PRECIP CHANCES WILL INCREASE AS  
A CLOSED UPPER LOW MOVES BEGINS LIFTING OUT OF THE DESERT  
SOUTHWEST TOWARDS THE THE PLAINS.
