All-Time Heat Record in Tasmania


An intense summer heatwave with temperatures in excess of 45°C in mainland Australia has spilled over to Tasmania, where Hobart has reported its all-time record hottest day in 132 years of climate data on January 4 (Australian time). Weather Channel Australia reports:
Hobart recorded it’s hottest day in 132 years of records just before 2pm today, with 41.3˚C. This broke the previous record of 40.8˚C recorded on January 4, 1976.

Overnight the temperature in Hobart remained above 25˚C, 13˚C above average and the warmest part of the state. The official low will be recorded as 23.6˚C from 9am yesterday, Hobart's highest January minimum on record.

The extreme heat is due to a northerly airstream from the mainland. The northerlies will strengthen today, causing severe to extreme fire dangers through eastern, central and northern Tasmania.

Record Warmest Year in Midwest


The National Weather Service has reported that 2012 was the record or near-record warmest year at many major climate locations across all of the Midwest. Most of these include periods of record dating back at least a century:
Illinois:
THE AVERAGE TEMEPRATURE FOR 2012 FOR CHICAGO WAS 54.5   
DEGREES...MAKING THIS THE WARMEST YEAR ON RECORD. THE PREVIOUS

RECORD WAS 52.8 DEGREES IN 1931.   
  
RECORDS FOR ROCKFORD DATE BACK TO 1906.

2012 RANKED AS THE SECOND WARMEST YEAR ON RECORD FOR BOTH PEORIA AND  
SPRINGFIELD.  AN UNUSUALLY WARM JANUARY THROUGH JULY PERIOD...INCLUDING 
UNPRECEDENTED MARCH  TEMPERATURES...CONTRIBUTED TO THE OVERALL WARMTH THIS
