Austin weather records

Austins record low was -2 degrees in Fahrenheit and that was in January of 1949 since then we have not hit lower but get a little bit more recent of a record but for the highs in 2000 we hit 112F in September? To say the least we have a weird weather schedule. In general the temperature is low 40s to 70s and the highs from 60s to 90s and the month with the most rain is most of the time in May around four inches of water. Lately its been much colder than previous times staying in the low 30s sometimes getting ice and then the next day jumping back up to the 80s.
