MAXIMUM Rain Rate:	0.27	25th @ 0615, but with caveat: Rain collector heater was turned on at 0607 so the higher rate was caused by the

                                it was going to stay warm enough that the heater wouldn't be needed. If temperatures are too warm... the heater
                                can cause unnecessary evaporation of lighter precipitation.
