The official hottest temp. ever recorded is 134 in Death Valley, California, but this record is not considered reliable by many meteorologists. Somewhere around 54C (or 129.2) is more likely, and we may have reached or passed it today in Kuwait and Iraq. More about this from Jason Samenow at Capital Weather Gang, and also from Jeff Masters at Weather Underground.
Below is global model data forecast of temps. for the region Friday. Notice it the forecast temps. are at the top of the chart! (NOAA Experimental FIM model)
