April 22nd, 2012 will go down in the books as the 2nd earliest date for the mercury to reach the century mark in Tucson. The only other time we have reached 100 degrees earlier in the year was April 19, 1989. On average, the first 100 degree day in Tucson occurs on May 26th and last year we didn't reach the 100 degree mark until May 27th. The latest date to climb to 100 degrees for the first time in a given year was June 22, 1905.
Along with moving into 2nd place on the all-time earliest day to reach 100 degrees, we also managed to break the record high temperature on Earth Day (Sunday). The old record high for April 22nd was 98 degrees back in 1965. The mercury soared to 101 degrees at the Tucson International Airport and that now becomes the new record high for April 22nd.
The record-breaking heat won't last long as a low pressure system from the west will bring cooler weather to the area by the middle of the week. By Thursday the high temperature is only expected to climb to the 70s with a chance of afternoon and evening thundershowers. We got a little taste of what's to come this weekend so take the 80s while you can because the 100 degree temperatures will come back soon enough.
