...SOME FREEZING RAIN POSSIBLE ON SUNDAY...

A DRAMATIC CHANGE IN THE WEATHER IS EXPECTED OVER THE NEXT 24 HOURS. 
A COLD FRONT MOVING THROUGH THE REGION WILL BE DELIVERING MUCH 
COLDER AND OF EQUAL IMPORTANCE DRIER AIR TONIGHT. 

A HIGH PRESSURE SYSTEM WILL BUILD OVER NEARBY CANADA AND KEEP A 
FRESH SUPPLY OF COLDER AND DRIER AIR INTO THE REGION INTO SUNDAY 
MORNING. AT THE SAME TIME A WARM FRONT ASSOCIATED WITH A WEAK LOW 
PRESSURE SYSTEM EXITING THE ROCKIES WILL WORK ITS WAY TOWARD US 
RAPIDLY. 

THIS QUICK CHANGE AND A RAPID INCREASE IN CLOUDS TOWARD MORNING IS 
EXPECTED TO TRAP SOME OF THE FRESH COLD AND DRY AIR NEAR THE SURFACE 
SUNDAY MORNING. IF PRECIPITATION ARRIVES QUICKLY ENOUGH ON 
SUNDAY, SOME OF IT MIGHT FALL AS FREEZING RAIN.

THE RECORD BREAKING HIGH TEMPERATURES TODAY AND THE FACT THE 
PRECIPITATION WILL BE FALLING DURING THE DAYTIME SUNDAY WILL HELP 
MITIGATE SOME OF THE PROBLEMS. NEVERTHELESS, SOME ICING MIGHT FORM 
ON EXPOSED SURFACES AND ON BRIDGES AND OVERPASSES WHICH ARE NOT IN 
CONTACT WITH THE WARMER GROUND.

TEMPERATURES ARE EXPECTED TO RISE ABOVE FREEZING BY AFTERNOON AND 
END THE THREAT OF FREEZING RAIN. DEEPER COLD AIR AND A MORE 
PROTRACTED FREEZING RAIN PROBLEM IS EXPECTED FARTHER TO THE NORTH IN 
PENNSYLVANIA AND NEW YORK ON SUNDAY.

PERSONS WITH TRAVELING PLANS ON SUNDAY ARE ADVISED TO LISTEN FOR 
FURTHER STATEMENTS OR ADVISORIES. PLEASE BE WARY FOR CHANGING ROAD 
CONDITIONS AND ESPECIALLY WHEN TRAVELING ON BRIDGES AND OVERPASSES.

AN ACTIVE WEATHER PATTERN MIGHT CAUSE A COUPLE OF OTHER MIXED 
PRECIPITATION EVENTS TO OCCUR.
