TAF SUMMARY:
A HIGH OVER NSW DIRECTS A NORTH TO NORTHWESTERLY AIRFLOW OVER SYDNEY
WITH A COLD FRONT TO THE WEST WHICH WILL MOVE THROUGH SYDNEY LATE
TONIGHT OR EARLY SUNDAY MORNING. SOME HIGH CLOUD AND LIGHT RAIN IS
AFFECTING THE SYDNEY AREA (AND HAS ARRIVED A LITTLE EARLIER THAN
ANTICIPATED), AND WILL MOST LIKELY CLEAR BY THE AFTERNOON. WARM,
FRESH AND GUSTY NORTHWEST WINDS WITH MODERATE TURBULENCE ARE EXPECTED
FOR MOST OF THE DAY BEFORE A WEST TO SOUTHWEST CHANGE ACCOMPANIES THE
FRONT, THE MOST PROBABLE TIME OF THE CHANGE BEING LATE TONIGHT.
THUNDERSTORM POTENTIAL:
NIL CHANCE WITHIN 20NM OF SYDNEY AIRPORT.
OTHER POSSIBILITIES:
30% CHANCE OF NW WIND GUSTS REACHING 40 KNOTS LATER THIS AFTERNOON.
THE COLD FRONT WILL MOVE THROUGH AS A WEST TO SOUTHWEST WIND CHANGE
TONIGHT/EARLY SUNDAY. IT MAY BE AS EARLY AS 0900Z - +20 KNOT
CROSS-WINDS A CHANCE WITH THIS FRONT.
ANY RAIN TODAY IS LIKELY TO BE LIGHT AND PATCHY.
SMALL CHANCE OF ISOLATED THUNDERSTORMS TODAY ON THE RANGES TO THE
WEST - MORE THAN 20NM FROM SYDNEY AIRPORT.

SUNDAY : FINE. WIND EASING. CITY MAX: 20
MONDAY : FINE. MOSTLY SUNNY. CITY MAX: 21
