===Snowfall===
The Blue Mountains has a reputation for snow in winter. However, despite the cool temperatures, there are only around five snowy days per year in the upper mountains area. It is extremely rare to see snow below [[Lawson, New South Wales|Lawson]]. It is not unusual to see white blankets of [[frost]] covering the ground in the early morning hours. In the evening, thick coverings of ice can form on car [[windscreen]]s.<ref>{{cite web |url=https://www.bluemts.com.au/info/about/climate/ |title=About the Blue Mountains Weather and Climate |work=web page |publisher=Blue Mountains Australia |access-date=20 October 2018 |archive-date=21 October 2018 |archive-url=https://web.archive.org/web/20181021111506/https://www.bluemts.com.au/info/about/climate/ |url-status=live }}</ref> 

Moreover, winters are not as snowy and rainy as those of [[Orange, New South Wales|Orange]] and [[Oberon, New South Wales|Oberon]], to the west; this is due to the fact Katoomba mostly lies on the [[leeward]] (eastern) side of the ranges, thereby experiencing a moderate [[southeast Australian foehn|foehn effect]].<ref>[https://www.willyweather.com.au/news/5291/rain+shadows.html Rain Shadows] by Don White.

Several significant snowfalls have been recorded. On 5 July 1900, [[snowdrift]]s were over {{convert|6|ft|order=flip}} deep in parts of the Blue Mountains. The snow and ice caused significant problems throughout central [[New South Wales]], with rail and road closures, damage to buildings, and disruption to [[telegraph]] services. A winter storm on 17 July 1965 also produced very heavy snow and ice in the area, with damage to buildings and major difficulties with road and rail transport. More recently, a cold snap brought heavy snow, up to {{convert|20|cm|abbr=on}}, to Katoomba and other towns in the upper Blue Mountains on 17 July 2015 which was the heaviest snowfall in many years.
