Hottest rain on record? Rain falls at 109F in Saudi Arabia
June 2012
Jeff Masters  -  Pilgrims to the holy city of Mekkah (Mecca), Saudi Arabia must have been astonished on Tuesday afternoon, when the weather transformed from widespread dust with a temperature of 113F (45C) to a thunderstorm with rain. Remarkably, the air temperature during the thunderstorm was a sizzling 109F (43C), and the relative humidity a scant 18%. It is exceedingly rare to get rain when the temperature rises above 100F, since those kind of temperatures usually require a high pressure system with sinking air that discourages rainfall. However, on June 4, a sea breeze formed along the shores of the Red Sea, and pushed inland 45 miles (71 km) to Mekkah by mid-afternoon. Moist air flowing eastwards from the Red Sea hit the boundary of the sea breeze and was forced upwards, creating rain-bearing thunderstorms. According to weather records researcher Maximiliano Herrera, this is the highest known temperature that rain has fallen at, anywhere in the world. He knows of one other case where rain occurred at 109F (43C): in Marrakech, Morocco on July 10, 2010. A thunderstorm that began at 5 pm local time brought rain at a remarkably low humidity of 14%, cooling the temperature down to 91F within an hour.

More like a hot shower than a cooling rain?
Thunderstorms often produce big drops of cold rain, since these raindrops form several thousand meters high in the atmosphere, where temperatures are much cooler than near the surface. Some drops even get their start as snow or ice particles, which melt on the way to the surface. Additional cooling of the drops occurs due to evaporation on the way down. However, in the case of the June 4, 2012 Mekkah storm, I think the rain was probably more like a hot shower. Large raindrops, like the kind thunderstorms produce, fall at a speed of about 10 meters per second. A balloon sounding of the upper atmosphere taken at 3 pm local time at a nearby station (Al-Midinah) found that the bottom 1000 meters of the atmosphere was 97F (36C) or warmer. Thus, the thunderstorms' raindrops would have been subjected to 100 seconds of some very hot air on the way to the surface, likely warming them above 100F by the time they hit the ground. A classic 1948 study of raindrops found that, in many cases, raindrop temperatures start off cold in the first few minutes of a rain shower, then warm up to within 1C (1.8F) of the air temperature within a few minutes. With the air temperature a sizzling 109F (43C) at the time of the June 4 thunderstorm in Mekkah, the raindrops could easily have been heated to a temperature of over 105F (41C) by the time they reached the surface!

How hot can it be and still rain?
If substantial amounts of liquid water are present on the Earth, the planet will experience rain, as long as some mechanism to lift the warm, moist air and cause condensation can be found. If the climate continues to warm as expected, we should see an increasing number of cases where it rains at temperatures well above 100F. On Saturday, June 2, the temperature in Mekkah hit 51.4C (124.5F), a new record for the city, and just 1.1F (0.6C) below the all-time hottest temperature record for Saudi Arabia (125.6F, or 52C, recorded at Jeddah on June 22, 2010.) I expect that 20 - 40 years from now, we'll begin seeing occasional cases where rain falls at a temperature above 117F (47C) in the desert regions of North Africa and the Middle East.

Saudi Arabia ice flood
Nov. 2, 2015
-  Saudi Arabia has been hit by unprecedented ice flash floods, as seasonal low pressure brings huge downpours to Iraq and Iran as well. The video shows chunks of ice the size of large ball bearings.  Extreme weather conditions have been lashing the country since October 28. Forum Index -> EARTH, Quakes, Weather
