The highest temperature I recall seeing for Mars was about 80 F, but according to Extreme Planet Takes Its Toll (12 June 2007) the temperature extremes measured by the Spirit Rover go from a low of about -130 F to +95 F, which is warmer than I expected. Those temperatures are measured at the rover, on the surface. Since the atmosphere is very thin, the temperature falls off fast with altitude. So it will not be warm enough even in the lower atmosphere for water to do the rain thing.
