IF YOU have turned to your woollies earlier in the year than expected, do not be alarmed as it turns out all of New South Wales is feeling the pinch of the overnight chill.

Winter has arrived in an overstated fashion with the overnight temperatures reduced to less than five degrees, and according to the Bureau of Meteorology it really feels a lot worse.

"The temperatures that are recorded are not what we actually feel," bureau forecaster Mohammed Nabi said. "If there is a little bit of wind about it creates a wind chill factor which moves the cold air over people quicker. This works to cool people down even more than the temperature recorded."

Mr Nabi said that the current cold snap in the Valley was the result of weather happenstance.

"What sometimes happens is we get these cold blasts, or as I like to call them 'Antarctic blasts'," Mr Nabi said. "They are large hypersystems drawing up colder air from the Antarctic systems and pulling them up to NSW.

"With a hypersystem sitting above us there is less cloud at night; clouds act as a blanket, so take the clouds away and you get more cold air around us."
