Lebanon and the eastern Mediterranean basin stand at the heart of a contradictory climate equation that combines exceptional and rising warmth with thunderous autumn fluctuations on the horizon. A stable, warm air mass dominates, pushing temperatures to levels above their usual seasonal levels, paving the way for spring-like weather that will last until Sunday afternoon, before the weather system suddenly breaks, giving way to a volatile depression accompanied by thunder, scattered rain, and active winds.
